Barnes & Noble has done the world a tremendous favor, by pulling aside the curtain and revealing Microsoft's patent campaign tactics against Android in lurid detail. It reveals the assertion of "trivial" and "invalid" patents against Barnes & Noble and some shocking details about an "oppressive" license agreement that would have controlled hardware and software design features that Microsoft presented, thus limiting to what degree Barnes & Noble could offer upgrades and improved features to its customers if it had signed it, features it says none of Microsoft's patents cover. Microsoft worked so hard to keep it all secret, and I think you'll see why. It's ugly behind that curtain. We saw the letter to the ITC from Barnes & Noble, and the slide presentation to the US Department of Justice, attached as Exhibit C to the letter to the ITC, and both have been covered widely in the media. But now I'll show you the other exhibits, Exhibits A, B, D, E and F, so you can get the full picture of what Barnes & Noble is accusing Microsoft of doing. Take a look especially at Exhibit D, where there is a long detailing of the incredibly insignificant patents Microsoft has the nerve to use against Android, claiming control of the entire operating system with what is pretty much a handful of stupid patents no one really needs or which are so trivial that the fees it claims become outrageous. At least that is Barnes & Noble's position. It made my blood boil to read it. As always, if you shouldn't look at patents, don't click to read the rest of the article.

Bresnahan The patents, we read, "cover only arbitrary, outmoded and non-essential design features" and yet Microsoft is demanding "prohibitively expensive licensing fees", in effect asserting "veto power" over Android's features. One aspect of the license, Barnes & Noble tells us, was a demand to control design elements, requiring designers to adhere to specific hardware and software specifications in order to obtain a license. That, Barnes & Noble says, is "oppressive and anticompetitive". I think it's accurate to say that the company believes it is illegal. Barnes & Noble asserts that Microsoft is attempting "to use patents to drive open source software out of the market," saying it, in essence, is acting like a patent troll, threatening companies using Android with a destructive and anticompetitive choice: pay Microsoft exorbitant rates for patents, some trivial and others ridiculously invalid or clearly not infringed, or spend a fortune on litigation. A large company like Amazon might be able to pay, but Barnes & Noble can't afford to pay such rates, which in any case it believes are ridiculous, given the quality of the patents, or lack thereof: In addition to the oppressive restrictions and prohibitions in Microsoft's proposed licensing agreement, Microsoft is also demanding exorbitant licensing fees for the use of Android. Indeed, shortly after Microsoft sent Barnes & Noble a proposed licensing agreement on or about January 6, 2011, Microsoft confirmed to Barnes & Noble that it was demanding licensing fees [redacted] for each NookTM and [redacted] for each Nook ColorTM. It is Barnes & Noble's understanding that these licensing fees that Microsoft demands for the use of the Android are the same, or higher, than the licensing fees that Microsoft charges for its own Windows Phone 7 -- despite the fact that Microsoft only claims ownership of only trivial and non-essential design elements in Android-based devices, as opposed to an entire operating system. Why is Microsoft doing this? Why, I can't help but wonder also, does it think it can do it and suffer no legal consequences? In one letter to the US Department of Justice, asking it to initiate an investigation, Barnes & Noble put it succinctly: Simply put, Microsoft is attempting to monopolize the mobile operating systems market and suppress competition by Android and other open source operating systems by, inter alia, demanding oppressive licensing terms directed to the entirety of Android, asserting this dominant position over Android on the basis of patents covering only trivial design choices and entering into a horizontal offensive patent agreement with Nokia.... Instead of focusing on innovation and the development of new products for consumers, Microsoft has decided to invest its efforts into driving open source developers from the mobile operating systems market. Through the use of offensive licensing agreements and the demand for unreasonable licensing fees, Microsoft is hindering creativity in the mobile operating systems market.... Through the use of oppressive licensing terms that amount to a veto power over a wide variety of innovative features in Android devices of all kinds, as well as its prohibitively expensive licensing fees, Microsoft is attempting to push open source software developers out of the market altogether. In discussions with Microsoft, Barnes & Noble says, Microsoft itself was unable to fully explain how the Nook or Nook Color infringed one of the patents asserted. Would you like to know the details? Here's how it went down, according to Barnes & Noble: In July 2010, Microsoft first met with Barnes & Noble to discuss "patent issues" related to Barnes & Noble's eReader. Microsoft specifically alleged that Barnes & Noble's NookTM was infringing six patents purportedly owned by Microsoft. When Barnes and Noble asked Microsoft for more detailed information related to these patents, Microsoft refused, claiming that the information was confidential and could not be shared unless Barnes & Noble first executed a non-disclosure agreement ("NDA"). Because both the patents and Barnes & Noble's NookTM product are public -- meaning there was no need for an NDA -- Barnes & Noble refused to sign one. In December 2010, Microsoft and Barnes & Noble then met to discuss Microsoft's assertions of patent infringement. In this meeting, Microsoft claimed that its patents were sufficient to entirely dominate and control the use of the Android by the NookTM or Nook ColorTM, but Microsoft again refused to provide the basis for these claims unless Barnes & Noble entered into an NDA. To move the process forward, Barnes & Noble agreed to a very narrow NDA -- one limited in scope to discussions relating to Microsoft's claim charts at this single meeting. In January of 2011, Microsoft then sent a proposed patent license agreement to Barnes & Noble. Although, as noted, the NDA executed in December was narrow and applied only to discussions of claim charts, Microsoft asserted that its proposed license agreement was confidential and subject to this NDA (which it is not). This proposed licensing agreement covered Barnes & Noble's use of Android on its existing eReader devices but is structured in such as way as to presume that Microsoft's portfolio of patents dominate, and thereby control, the entire Android operating system and any devices that use Android. Indeed, the proposed license would have severely limited and, in some cases, entirely eliminated Barnes & Noble's ability to upgrade or improve the NookTM or Nook ColorTM, even though Microsoft's asserted patents have nothing to do with such improvements. It is bullying, Barnes & Noble seems to be saying, in that Microsoft is asking for rates comparable to what it would charge for an entire operating system, claiming credit for Android, but when you look at the patents, they are for things that are utterly trivial or, in some cases -- a patent that only comes into play on dial-up connections, which obviously the Nook doesn't need -- for functionality Barnes & Noble products don't use or need. Even when it might need it in peripheral scenarios, the patents are so utterly in the insignificant category, it's overreaching to try to charge what Microsoft is asking for them, or to block from the market, the entire Android operating system, which Microsoft didn't invent. As for the proposed licensing agreement, here's what Barnes & Noble says about it: Microsoft's assertion of confidentiality is simply a means to cloak its oppressive and anticompetitive licensing proposal and is another element in Microsoft's larger scheme to restrict competition in the mobile operating systems market. The patents that Microsoft is asserting against Barnes & Noble do not even purport to cover hardware elements or basic software functions for mobile devices, and Microsoft thus has no right to require designers to adhere to any particular hardware or software specifications in order to obtain a license for those patents. Yet Microsoft is doing just that -- abusing and seeking to expand the scope of its patents to control design elements over which Microsoft has no legitimate claim. This conduct is plainly anticompetitive and threatens Barnes & Noble's ability to modify and offer improved products to consumers. Have others signed such agreements? If so, why would we want to buy their hobbled products? Why are they not instead doing what Barnes & Noble is doing? Seriously, Amazon et al. Why? In footnote 4 in Exhibit B, Barnes & Noble says it signed, along with HTC, to avoid the costs of litigation. It reminded me of the US Supreme Court Justice who asked recently in one oral argument session if the USPTO had really issued a lot of invalid patents? Was it really a problem? I hope if that question arises again, someone shows them the Barnes & Noble exhibits. They demonstrate, to me, anyway, that there is a major problem, one so serious it is possible for a cynical player to use stupid patents that should never have issued and figure they can get away with it. Wait til you see these patents and what Barnes & Noble says about each one. He might also want to take a look at The Private and Social Costs of Patent Trolls, by James Bessen, Jennifer Ford, and Michael J. Meurer: Abstract In the past, non-practicing entities (NPEs)  firms that license patents without producing goods  have facilitated technology markets and increased rents for small inventors. Is this also true for todays NPEs? Or are they patent trolls who opportunistically litigate over software patents with unpredictable boundaries? Using stock market event studies around patent lawsuit filings, we find that NPE lawsuits are associated with half a trillion dollars of lost wealth to defendants from 1990 through 2010, mostly from technology companies. Moreover, very little of this loss represents a transfer to small inventors. Instead, it implies reduced innovation incentives. What stands out to me also, in perusing the exhibits, is how long this has been going on, as Exhibit A is a Barnes & Noble letter to the US Department of Justice dated March 28, 2011. It turns out that Barnes & Noble also wrote in that letter to complain about the then-proposed sale of Novell patents to CPTN in that letter, and the letter reveals that the Commerce One patents Novell purchased in 2005, beating out Intellectual Ventures, and then donated as the foundation patents to create OIN's patent sharing safety zone, were patents that Barnes & Noble worried might end up in Microsoft's hands if it was allowed to buy Novell's patents. So now we know what all that was about. As you know, the complaints about the sale bore some fruit, so let's start with that exhibit and follow the story as it unfolded. This is what I love about the law, one of many things -- that you find out what *really* happened behind the closed doors by means of legal filings. So, let's start with Exhibit A, back when it was Barnes & Noble's General Counsel writing to Christine Varney, then Assistant Attorney General, Antitrust Division, at the DOJ. Varney now works at Cravath, which as I pointed out in an update to our earlier article means she can't appear before the DOJ on any matter that she was involved in while at the DOJ. Here's the letter, as text: EXHIBIT A [Barnes & Noble Letterhead] March 28, 2011 The Honorable Christine Varney

Assistant Attorney General

Antitrust Division

United States Department of Justice

[address] Dear Assistant Attorney General Varney, Barnes & Noble submits this letter: (1) to object to the anticompetitive effects of Novell's sale of 882 patents to CPTN Holdings LLC, a consortium of companies led by Microsoft, and (2) to request that the DOJ initiate an independent investigation regarding Microsoft's anti-competitive behavior surrounding its actions to suppress Android operating system competition, and (3) to seek DOJ to petition the International Trade Commission ("ITC") to dismiss Microsoft's anti-competitive Android related patent action against Barnes & Noble. In our opinion as a competitor that uses the Android operating system and as a victim of Microsoft's attempts to use patents to drive open source software out of the market, we believe that the sale of Novell's patents is another element of Microsoft's attempts to monopolize the operating system markets. Microsoft has shown in the past year that it will use any patents it owns to bully smaller companies out of the market with threats of litigation and forced licenses, as it attempted to claim ownership of the Android operating system used in Barnes & Noble's NookTM e-Reader, as well as Android smartphones, the Kindle e-Reader, and many other popular consumer devices. In the context of Microsoft's behavior regarding the Android operating system and similar behavior regarding Google's open source VP8 video codec, its acquisition of Novell's patents can only be seen as part of an attempt to claim ownership of any free operating system that might compete with Microsoft. Microsoft's business practices, and the acquisition of yet more patents that could be used to suppress competition from open source software, would certainly have the effect of substantially lessening competition, or tending to create a monopoly. As you are well aware, members of the open-source community have expressed apprehension with regard to Novell's potential sale to Microsoft. The reason for this apprehension in part stems from Novell's acquisition of patents in 2005, which may be part of the current transaction between Novell and Microsoft. Novell is a member of the Open Invention Network (OIN) which claims to enable and protect certain open source software. In 2005 Novell, as a subsidiary of OIN, acquired a set of patents from Commerce One focusing on XML and e-commerce, for which OIN subsequently offered royalty free nonexclusive licenses. Although the details of the March 28, 2011

Page 2 882 patents Microsoft is attempting to purchase are not public, there is a concern that this deal will result in Microsoft's ownership and enforcement of patents, including the Commerce One patents and others that may read on the underpinnings of open source computing, which could cripple open source computing. Microsoft's acquisition in 2005, along with its attempted purchase of Novell's patents and numerous other actions, show a pattern of attempts to dominate and either drive out or reduce competition from open source software. This pattern of behavior most recently came to the fore on Monday, March 21, 2011, when Microsoft filed complaints for patent infringement against us in the Western District of Washington and before the International Trade Commission, alleging that Barnes & Noble's NookTM eReaders, which use the Android operating system, infringe Microsoft's patents. It is clear from Microsoft's actions and statements that its issue is not with Barnes & Noble, but instead is with the Android operating system developed by Google, which has achieved in a short period what Microsoft, with all its resources, has failed to do over the past years. Namely, to develop a mobile operating system that would be embraced by both mobile smart device manufacturers and by the public, and for Microsoft to eliminate competition. Instead of directly addressing this issue with Google, Microsoft has decided to target Barnes & Noble, who merely incorporates the Android operating system into its eReaders. The filing of the actions also included a press release by Microsoft and blog entries by Horacio Guitierrez, Microsoft's Deputy General Counsel, suggesting that it is a foregone conclusion that Barnes & Noble and other Android operating system users must take a license from Microsoft and pay it royalties is disputed by Barnes & Noble, just as other handheld device manufacturers have disputed this assertion. There is no legitimate basis for Microsoft's assertion of dominance over the Android free-source operating system which was not invented at or by Microsoft, but instead was developed in large part by Google. The suit and ITC actions filed by Microsoft against Barnes & Noble and its suppliers is more akin to the conduct of what has come to be known as a "Patent Troll" than to the actions of an innovative R&D-based high-tech company. Microsoft in apparently seeking to dominate the operating system marketplace, serves no public interest, and will instead serve only to stifle innovation and competition. Over the past year, Microsoft has aggressively worked to force companies manufacturing products that use the Android operating system to take a prohibitively expensive license to Microsoft's patents. As Microsoft is in the market for smartphones and tablets, these licenses raise competitors' costs and reduce their ability to compete with Microsoft's products, such as smartphones using Microsoft's Windows Phone 7 operating system. Barnes & Noble, a small player in the eReader market, could not agree to Microsoft's extortionate license (and also does not believe the infringement claims to be valid), and when we refused to pay, Microsoft filed its lawsuit. March 28, 2011

Page 3 Microsoft's press release regarding its lawsuit against Barnes & Noble states that the Android platform generally infringes Microsoft's patents, and that all Android device manufacturers must license Microsoft's patents.1 Microsoft's corporate vice president stated that it would be forced to assert its patents against any company whose products run the Android operating system; such companies would either have to take an expensive license from Microsoft or fight a protracted and costly battle in federal court.2 These statements show an intent to force any user of the Android operating system to pay an expensive license or get out of the market. That behavior reduces competition and innovation, as Google, in a public statement, said: "Sweeping software claims like Microsoft's threaten innovation." The patents Microsoft is asserting against Barnes & Noble relate to features that add absolutely trivial, if any, value to handheld devices such as the NookTM eReader. Microsoft's lawsuit against Barnes & Noble is therefore not a legitimate attempt to protect actual invention, but a misuse of acquired patents to bully a competitor into taking an unaffordable license. It is also a tactic that would become available in even more market areas Microsoft wishes to dominate should the purchase of Novell's patents be allowed. Microsoft has shown its intent to drive out other open source software using overaggressive patent enforcement. The Microsoft dominated MPEG-LA consortium recently sent out a request for patents that would cover Google's VP8 video codec, and one company has already filed a private antitrust complaint against MPEG-LA for this behavior.3 MPEG-LA is a patent pool organized to collect and license patents on the H.264/MPEG video codec, a method of digitally encoding video files and decoding them for playback. Google is attempting to introduce its own codec, the VP8 codec, to compete with the MPEG codec. Once again, by seeking non-essential patents to assert offensively rather than defensively, Microsoft intends to drive out competition from open source developers. Microsoft had already tried and failed in 2007 to overpower open source software subject to the GNU Public License (GPL), in a scheme conducted in concert with Novell. Given Microsoft's history, it must be assumed that it intends to use any patents it acquires to dominate the open source software market. Microsoft's patent acquisition and litigation practices lessen competition in multiple ways. Microsoft's willingness to bully small players with expensive litigation raises a substantial barrier to entry in any market in which it claims dominance. Microsoft's exorbitant licenses for its patents entrench the dominant players in the relevant markets because those players can afford to take a license, while small players cannot -- for example, in the eReader market, dominant Amazon could afford Microsoft's fees, which the small competitor Barnes & Noble could not. Similarly, very small players such as independent developers not only cannot afford Microsoft's _____

Microsoft's license fees are set at a high enough level that it also reduces competitor's abilities to compete with Microsoft's own products, such as smartphones using the Windows Phone 7 operating system. In addition to harming competitors, this behavior directly harms consumers, who often prefer systems using open source operating systems such as Android and Linux to Microsoft's operating systems, and who will never realize the benefit from independent developers that Microsoft drives out of the software industry. Sincerely, [signature]

Eugene V. DeFelice

Vice President, General Counsel & Secretary Here's Exhibit B, the April 2011 letter to the DOJ, asking them to initiate "an investigation of Microsoft's anticompetitive conduct in the mobile operating systems market", as text: EXHIBIT B [Barnes & Noble letterhead] VIA FEDERAL EXPRESS April 25, 2011 James J. Tierney

Chief, Networks and Technology Enforcement Section

Antitrust Division

United States Department of Justice

[address] Dear Mr. Tierney: On March 28, 2011, Barnes & Noble submitted a letter (a copy of which is attached) to the Antitrust Division objecting to the proposed acquisition of close to 900 Novell patents by CPTN Holdings, LLC ("CPTN"), a consortium of companies led by Microsoft. As described in that letter, Barnes & Noble objected to the acquisition as part of Microsoft's larger scheme to drive open source software -- including the Android Operating System ("Android") -- out of the mobile operating systems market. Although we understand Microsoft subsequently agreed to modify the CPTN-Novell deal in order to try to address antitrust concerns -- and that, in light of these modifications, the Department decided not to challenge the transaction1 -- Barnes & Noble continues to be deeply concerned with Microsoft's anticompetitive behavior in the market for mobile operating systems. This anticompetitive behavior extends well beyond the CPTN transaction and continues unabated. Simply put, Microsoft is attempting to monopolize the mobile operating systems market and suppress competition by Android and other open source operating systems by, inter alia, demanding oppressive licensing terms directed to the entirety of Android, asserting this dominant position over Android on the basis of patents covering only trivial design choices and entering into a horizontal offensive patent agreement with Nokia. _____________

Page 2 of 6 All of these actions by Microsoft pose serious anticompetitive concerns. Indeed, the Department of Justice's prior concern that the CPTN-Novell transaction would "jeopardize the ability of open source software, such as Linux, to continue to innovate and compete in the development and distribution of server, desktop, and mobile operating systems, middleware, and virtualization products", remains equally valid with respect to Microsoft's other anticompetitive behavior. I. Microsoft's Demand for Oppressive Licensing Terms and Exorbitant

Licensing Fees. Instead of focusing on innovation and the development of new products for consumers, Microsoft has decided to invest its efforts into driving open source developers from the mobile operating systems market. Through the use of offensive licensing agreements and the demand for unreasonable licensing fees, Microsoft is hindering creativity in the mobile operating systems market. In July 2010, Microsoft first met with Barnes & Noble to discuss "patent issues" related to Barnes & Noble's eReader. Microsoft specifically alleged that Barnes & Noble's NookTM was infringing six patents purportedly owned by Microsoft. When Barnes and Noble asked Microsoft for more detailed information related to these patents, Microsoft refused, claiming that the information was confidential and could not be shared unless Barnes & Noble first executed a non-disclosure agreement ("NDA"). Because both the patents and Barnes & Noble's NookTM product are public -- meaning there was no need for an NDA -- Barnes & Noble refused to sign one. In December 2010, Microsoft and Barnes & Noble then met to discuss Microsoft's assertions of patent infringement. In this meeting, Microsoft claimed that its patents were sufficient to entirely dominate and control the use of the Android by the NookTM or Nook ColorTM, but Microsoft again refused to provide the basis for these claims unless Barnes & Noble entered into an NDA. To move the process forward, Barnes & Noble agreed to a very narrow NDA -- one limited in scope to discussions relating to Microsoft's claim charts at this single meeting. In January of 2011, Microsoft then sent a proposed patent license agreement to Barnes & Noble. Although, as noted, the NDA executed in December was narrow and applied only to discussions of claim charts, Microsoft asserted that its proposed license agreement was confidential and subject to this NDA (which it is not). This proposed licensing agreement covered Barnes & Noble's use of Android on its existing eReader devices but is structured in such as way as to presume that Microsoft's portfolio of patents dominate, and thereby control, the entire Android operating system and any devices that use Android. Indeed, the proposed license would have severely limited and, in some cases, entirely eliminated Barnes & Noble's ability to upgrade or improve the NookTM or Nook ColorTM, even though Microsoft's asserted patents have nothing to do with such improvements. At the risk of inciting even more baseless litigation by Microsoft, Barnes & Noble does not feel comfortable sharing all of the details of the proposed license agreement in light of Microsoft's baseless assertion that it is confidential and covered by an NDA. Nevertheless, Barnes & Noble urges the CONFIDENTIAL INFORMATION REDACTED April 25, 2011

Page 3 of 6 Department of Justice to use its subpoena power to demand a copy of the proposed licensing agreement, and any other relevant documents, from Microsoft. Microsoft's assertion of confidentiality is simply a means to cloak its oppressive and anticompetitive licensing proposal and is another element in Microsoft's larger scheme to restrict competition in the mobile operating systems market. The patents that Microsoft is asserting against Barnes & Noble do not even purport to cover hardware elements or basic software functions for mobile devices, and Microsoft thus has no right to require designers to adhere to any particular hardware or software specifications in order to obtain a license for those patents. Yet Microsoft is doing just that -- abusing and seeking to expand the scope of its patents to control design elements over which Microsoft has no legitimate claim. This conduct is plainly anticompetitive and threatens Barnes & Noble's ability to modify and offer improved products to consumers.

Indeed, shortly after Microsoft sent Barnes & Noble a proposed licensing agreement on or about January 6, 2011, Microsoft confirmed to Barnes & Noble that it was demanding licensing fees [redacted] for each NookTM and [redacted] for each Nook ColorTM. It is Barnes & Noble's understanding that these licensing fees that Microsoft demands for the use of the Android are the same, or higher, than the licensing fees that Microsoft charges for its own Windows Phone 7 -- despite the fact that Microsoft only claims ownership of only trivial and non-essential design elements in Android-based devices, as opposed to an entire operating system. Through the use of oppressive licensing terms that amount to a veto power over a wide variety of innovative features in Android devices of all kinds, as well as its prohibitively expensive licensing fees, Microsoft is attempting to push open source software developers out of the market altogether. II. Microsoft's Assertion of Trivial and Non-Essential Patents. In seeking to extract its restrictive licensing terms and prohibitively expensive licensing fees, Microsoft is asserting patents that cover only arbitrary, outmoded and non-essential design features. As noted in Barnes & Noble's March 28, 2011 letter, Microsoft filed complaints in the U.S. District Court for the Western District of Washington and before the International Trade Commission alleging that Barnes & Noble's eReaders -- i.e. , the NookTM and the Nook ColorTM -- infringe five of these non-essential patents.2 Notably, in the discussions that preceded Microsoft's lawsuits, ________

2 Google, which has not been sued by Microsoft, issued a statement in response to Microsoft's litigation tactics in which it stated that "sweeping software-patent claims like Microsoft's threaten innovation. While we are not a party to this lawsuit [against Barnes & Noble], we stand behind the Android platform and the partners who have helped us to develop it". See "Microsoft takes aim at Google's Android again", available at

Page 4 of 6 Microsoft asserted that Barnes & Noble's NookTM products infringed six specific patents. However, when Microsoft sued, it did not even mention five of these patents, making claims based on only one of these patents plus four other patents that had never previously been discussed. All of these patents that Microsoft is seeking to use as means to suppress open source software in the mobile operating systems market cover trivial design elements such as the compatibility of file names between new and old operating systems or the placement of a loading status icon in the content viewing area of a browser. Indeed, Horacio Gutierrez, Microsoft' Corporate Vice President and Deputy General Counsel, has publicly stated that the five patents on which Microsoft has sued cover only (1) the "display of a webpage's content before the background image is received, allowing users to interact with the page faster"; (2) "easy ways to navigate through information provided by . . . device apps via a separate control window with tabs"; (3) "the select[ion] [of] text in a document and adjust[ment] [of] that selection"; (4) "the ability to annotate text without changing the underlying document"; and (5) permitting "apps to superimpose download status on top of the downloading content".3 None of these features drive consumer demand for Barnes & Noble's, or its competitors', products. And these trivial features do not give Microsoft lawful control over the market. Microsoft did not invent, research, develop or make available to the public mobile devices using the Android or other open source operating systems. Nonetheless, Microsoft has commenced a campaign to assert control over the open source Android by requiring Android users to either pay exorbitant licensing fees to Microsoft -- thereby, in essence, agreeing that Microsoft's trivial and non-essential patents in effect give it control of Android -- or face the costs of a protracted patent infringement lawsuit. And of course Barnes & Noble is not alone in being subjected to Microsoft's patent litigation campaign.4 By Microsoft's own count, twenty-five of its _________

3 Id. 4 In order to avoid the protracted costs of litigation, both HTC Corp., a large electronics manufacturer, and Amazon, which sells the Kindle eReader, have entered into license agreements with Microsoft. See "Microsoft and Amazon.com Sign Patent Agreement", available at http://www.microsoft.com/presspass/press/2010/feb10/02-22msamazonpr.mspx; "Microsoft Announces Patent Agreement with HTC", available at http://www.microsoft.com/presspass/press/2010/apr10/04-27mshtcpr.mspx. In contrast, because Motorola could not agree with Microsoft on a licensing agreement, Microsoft filed a lawsuit against Motorola for patent infringement.

Page 5 of 6 patents are now "in litigation for infringement by Android smartphones, tablets and other devices".5 III. Microsoft's Anticompetitive Agreement with Nokia Microsoft's anticompetitive conduct and intent to drive open source developers out of the market is further evidenced by its recent horizontal offensive patent agreement with Nokia. On February 11, 2011, Microsoft announced plans to form a strategic partnership with Nokia. As part of those plans, Microsoft is paying Nokia $1 billion and Nokia is committing to replace its Symbian operating system with Microsoft's Windows Phone 7 operating system as "its principal smart phone strategy".6 Microsoft is thus paying to drive one competitive operating system out of the market and to substantially increase Microsoft's footprint in the mobile operating systems market. In the fourth quarter of 2010, Nokia was the second largest smartphone provider, with a global market share of 30.6 percent, and Microsoft had a global market share of 3.1 percent (Microsoft has about a 10 percent share in the U.S. market). The only larger provider of smartphone operating systems besides Nokia is Google, with a global market share of 32.0 percent. Indeed, Microsoft and Nokia have identified Google's Android as their fiercest competition. As Nokia's CEO, Stephen Elop, stated to the press shortly after the Microsoft-Nokia partnership was announced, "This Windows phone ecosystem, more than anything else, must compete effectively with Android. . . ." and our "[n]umber one priority is to compete with Android".7 As part of Microsoft's and Nokia's strategy to "compete" with Android, Microsoft and Nokia have apparently agreed upon a strategy of coordinated use of their patents to drive out competitors -- that is, a horizontal offensive patent agreement. As Mr. Elop stated: It is the case, and it was absolutely a topic of discussion with Microsoft, that Microsoft plus Nokia has a remarkably strong intellectual property portfolio. That is something that we will use appropriately within the context of our ecosystem, which means both defending the ecosystem from outside attacks as well as appropriately ensuring that the value that _______________

Page 6 of 6 we have created through our patents are properly collected from other people who may choose to take advantage of that technology.8 Thus, instead of actually competing with the open source Android, Microsoft and Nokia have agreed to a coordinated offensive to assert patents in order to remove open source software from the market altogther. Microsoft's partnership with Nokia, coupled with Microsoft's demand for licensing fees for the use of Android, has created a great risk that Microsoft will garner substantial market power in the upstream market for operating systems. After Microsoft's CEO Steve Ballmer initially labeled the Android nothing more than a "press release" and contrasted Android with Microsoft's "many millions of customers, great software, many hardware devices" while "welcom[ing]" the Android to "[Microsoft's] world",9 Microsoft has now determined that Android is only welcome to the extent Microsoft controls the open source operating system through either exorbitant licensing fees or lengthy courtroom battles. By establishing "an industry-wide patent licensing program for Android device manufacturers",10 coupled with its partnership with Nokia, Microsoft has continued its campaign to control the mobile operating systems market -- i.e. , "[Microsoft's] world". * * * For the reasons outlined in this letter as well as those in Barnes & Noble's March 28, 2011 letter to the Department of Justice, Barnes & Noble respectfully submits that the Department of Justice should initiate an investigation of Microsoft's anticompetitive conduct in the mobile operating systems market. Please feel free to contact me if you have any questions about either of Barnes & Noble's letters. Sincerely [signature] Eugene V. DeFelice

http://www.pcworld.com/businesscenter/article/139421/google_android_just_a_press_release_says_ballmer.html. 10 Horacio Gutierrez, Corporate Vice President and Deputy General Counsel, "Android Patent Infringement: Licensing is the Solution", supra at note 2. [Ed: the remaining pages of this exhibit are the letter dated March 28, 2011 to the DOJ, which you can read as Exhibit A, above.] Later, in July of 2011, following a meeting with the DOJ, Barnes & Noble sent another letter, Exhibit D, from its outside law firm Kenyon & Kenyon, to a group of lawyers at the DOJ's Antitrust Division, specifically about the trivialness of the patents Microsoft is asserting. It's 32 pages, so here are the highlights, until we can do it as text in full: EXHIBIT D .... Microsoft has told Barnes & Noble that it has over 60,000 patents. Of the patents in its portfolio, Microsoft asserted only five patents against Barnes & Noble in the litigations (the same patents were asserted in both litigations). Prior to filing the actions, Microsoft has threatened Barnes & Noble with infringement claims in connection with six patents, only one of which was asserted in the litigations. All ten of the patents from its portfolio that Microsoft has identified to and asserted against Barnes & Noble are trivial in terms of both their commercial significance and patentability. [Lists the patents.]... These Microsoft patents can be divided into several basic categories: (1) the '372 and '780 patents relate to web browsers; (2) the '551 and '233 patents relate to electronic document annotation and highlighting; (3) the '522 patent relates to resources provided by operating systems; (4) the '517 and '352 patents deal with compatibility with file names once employed by old, unused, and outmoded operating systems; (5) the '536 and '853 patents relate to simulating mouse inputs using non-mouse devices; and (6) the '913 patent relates to storing input/output access factors in a shared data structure. Importantly, while Microsoft's infringement allegations appear to be centered on the Nook's and Nook Color's use of the Android operating system ("Android"), none of these patents are specific to or describe the novel technical features of Android. Microsoft cannot argue that it invented Android which, in fact, was the result of the exemplary effort of many talented programmers, including programmers in the open source community. Rather, as this letter highlights, the patents that Microsoft has asserted against Barnes & Noble -- patents that are part of the same portfolio that Microsoft has publicly alleged allows it to dominate the entire cell phone, tablet, e-reader, and other mobile device operating system market -- are nothing more than trivial implementations of known, non-essential features of an operating system. These trivial features, long present in the prior art, including highlighting documents, displaying the foreground of an electronic document before downloading background content, and locating a loading status icon over a content area rather than in a tool bar area. Moreover, and as one would expect in view of the triviality of the Microsoft patents, Barnes & Noble has formidable invalidity and non-infringement defenses in connection with the patent claims asserted by Microsoft in the litigations. Several (but certainly not all) of these defenses are summarized in this letter. Simply stated, the very nature of the patents asserted by Microsoft belies their public assertion of total dominance over the Android mobile operating system. The following includes a detailed discussion of the triviality of the asserted Microsoft patents in light of their commercial insignificance and legal weakness in terms of invalidity and non-infringement, namely for each of the five patents in the ITC and District Court actions, and a summary of the other patents Microsoft had identified to Barnes & Noble prior to filing the suits. I. '372 Patent (Web Browser Background Image Loading) The '372 patent was filed April 18, 1996. Very generally, the patent relates to an outmoded system for retrieving an electronic document like a webpage that includes an embedded background image, which may have a bearing on very old web browsers connected to the Internet via slow, dial-up connections, but has little application in the context of improved, modern Internet connections.... A. Invalidity As an example of its many invalidity defenses, the prior art web browser Netscape Navigator 2.0b3 and documents describing this browser, provide Barnes & Noble with a substantial defense that both asserted claims 1 and 5 of the '372 patent are invalid as anticipated. Netscape Navigator 2.0b3 is a particularly apt prior art reference because the '372 patent itself discusses and points out supposed shortcomings of an even earlier version of Netscape Navigator.... The '372 patent explains that this earlier version of Navigator would otherwise meet all of the limitations of the patent's claims, except that it "requests the background image and waits for the background image to arrive before displaying the HTML document. Once the background image is received, the Navigator then draws an initial display of the HTML document....Release notes and other documentation relating to Netscape Navigator 2.0b3, which again was available five months before the '372 patent was filed, state that this version of Navigator "no longer waits for the background image to completely arrive before displaying any text and images on the page. When the background image has been decoded the page is redrawn to include the background." This is the precise functionality that lies at the heart of claims 1 and 5 of the '372 patent. Among other reasons for invalidity, Barnes & Noble also has a substantial argument that asserted claims 1 and 5 of the '372 patent are invalid under 35 U.S.C. Section 112 for failing to provide an adequate written description of, or enable one skilled in the art to use, the subject matter embraced by those claims. While the specification notes the desired functionality of the claimed web browser, it provides no software code, points to no exemplary web browsers, and provides no other technical details explaining how a browser should actually go about producing an initial display without a background image, and then redraw that display with a background image.... This dearth of disclosure calls into question whether Microsoft even created a browser that fell within the scope of the claims of the '372 patent prior to its filing date. Further, if Microsoft did create such a browser, its failure to include technical details regarding that browser in the specification of the '372 patent violated Section 112's mandate that the specification set forth "the best mode contemplated by the inventor of carrying out [the] invention." In sum, Barnes & Noble maintains that the '372 patent inadequately describes a technique for downloading and displaying an electronic document having an embedded background image, and is anticipated and unpatentable in any event because the very functionality it purports to claim was already provided by a prior art Netscape browser before Microsoft filed its patent application. Moreover, as explained in further detail below, the very purpose of the '372 patent was to deal with the long wait times users were subjected to in the 1996 time frame (due to the use of slow, dial-up modems) when downloading and displaying complex electronic documents like webpages with embedded background images. Since Barnes & Noble's Nook and Nook Color products employ modern, high speed Internet connectivity and other related technology, the purported reduction in the perception of delay provided by the browser set forth in the '372 patent, and the prior art Netscape browser is irrelevant to and simply has no bearing on those products.... II. '522 Patent (Operating System Provided Tabs) The '522 patents was filed December 13, 1994. The patent relates to a single, simple tool provided by an operating system (such as Windows) that allows applications running on that operating system to have a common look and feel. Since operating systems provide many such tools, the patent amounts to nothing more than a trivial design choice. In particular, and despite the fact that this concept is in the prior art, the '522 patent's method allows for the creation of tabs. The tabs are analogous to dividers like those found in a notebook or to labels found in a file cabinet, and allow the user of an application to navigate between multiple pages of information in the same window by clicking on the tabs.... A. Invalidity A programming guide published by IBM in connection with its OS/2 2.0 operating system, entitled IBM OS/2 2.0 Programming Guide Volume II ("the Guide"), provides Barnes & Noble with one of many substantial defenses that asserted claims 1,2, and 12 of the '522 patent are invalid as anticipated. The Guide was published in 1992, and is thus prior art to the '522 patent pursuant to 35 U.S. C Section 102(b).... III. '551 Patent (Electronic Selection with "Handles") On its face, the '551 patent purports to claim priority back to a November 10, 2000 filing date. Generally, the '551 patent relates to another simple and trivial feature that is not only disclosed by numerous prior art references, but is certainly not central to an operating system like Android -- selecting or highlighting text or graphics within an electronic document. The patent provides that a user selects a word or phrase, for example, by tapping on a touch screen display or clicking with a mouse. Such a selection may be shown by highlighting the selected word or phrase. The user is presented with "selection handles" on one or both ends of the selected areas. These "selection handles" can be moved by the user to highlight more or less text or graphics.... A. Invalidity Among numerous other references, U.S. Patent No. 6,151,426 to Lee et al. ("the '426 Lee patent"), which issued November 21, 2000 and was filed October 1, 1998 (more than two years before the '551 patent) and is prior art Section 102(e), and U.S. Patent No. 6,683,631 to Carroll ("the '631 Carroll patent"), which issued January 27, 2004 and was filed December 31, 1998 (one year and nine months before the '551 patent) and is also Section 102(e) prior art, provide Barnes & Noble with a substantial argument that the asserted claims of the '551 patent are invalid as anticipated.... Barnes & Noble also has a substantial argument that asserted claims of the '551 patent's specification only describes the desired functionality, but does not provide code or other technical detail regarding how one of skill in the art would be able to accomplish the claimed selection methods.... IV. '233 Patent (Annotation of Electronic Documents) The '233 patent was filed December 7, 1999. Like the other Microsoft patents, the '233 patent relates only to one small feature that has long been present in the prior art and is not central to Android or any other operating system. More specifically, the patent generally relates to a method for capturing annotations made in an electronic document (like an electronic book), without changing the electronic document itself.... A. Invalidity While several other prior art references also apply to the '233 patent's claims, a document entitled Re: Mark Markup and Review for Adobe Acrobat Software User's Guide ("the Re:Mark Guide") anticipates claims 21 and 22 of the '522 patent. The Re:Mark Guide was published July 10, 1997.... V. '780 Patent (Web Browser Loading Status Icons) The '780 patent was not filed until May 6, 1997, long after the first web browser came to market. In addition to being late to the game, the patent is directed to a very simple and obvious feature -- a temporary graphic element or status icon that is displayed to indicate that a hypermedia browser (such as a web browser) is loading content. When a browser is intended for use with a portable computer system with a limited display size, the '780 patent notes that it is desirable to maximize the browser's content display area (the portion of the browser that actually displays a website, not the menus, toolbars, or buttons). Thus, the patent makes a trivial design choice and provides that the graphic element or loading status icon is to be temporarily displayed in the content display area of the browser as opposed to a separate space such as the browser's menu bar, tool bar, or a separate status bar.... A. Invalidity All the asserted claims of the '780 patent are obvious in view of a number of prior art references. While providing a complete listing of these references is beyond the scope of this letter, examples include the following: U.S. Patent No. 5,301,348 to Jaaskelainen ("the '348 Jaaskelainen patent"), which issued April 5, 1995.... [lists 3 others] It cannot reasonably be disputed that web browsers included loading status indicators when the '780 patent was filed.... Either alone or together, the references make clear that the concept of moving a loading status icon from a web browser's status bar to a location over the content viewing area (the sole feature that distinguishes the '780 patent from the prior art) was known, contemplated, and obvious to one of skill in the art.... VI. Other Patents Identified by Microsoft Prior to Filing Its Suits As noted above, in attempt to support its claim of dominance over Android, in addition to the '780 patent described above (the only overlapping patent that was asserted in the litigations as well as during discussions prior to the filing of the suits), Microsoft also identified five other patents to Barnes & Noble that are not at issue in the International Trade Commission and District Court actions. These include the '517, '913, '352, '536, and '853 patents. Like the patents asserted by Microsoft in the litigations, these other patents are also trivial and do not warrant dominance over an entire operating system. Indeed, the fact that Microsoft did not assert five of the six patents identified prior to the filings of its suit points to its own belief that the patents are trivial and do not cover an entire operating system. As Barnes & Noble highlighted in its Response it filed with the International Trade Commission, the '517 and '352 patents deal with nothing more than the compatibility between file names employed by operating systems used and sold today, and more primitive file names employed by old, unused, and outmoded operating systems. This is of no importance to either the Nook or Nook Color, which are more modern products. Neither product infringes any valid, enforceable claims of the '517 or '352 patent. The '536 and '853 patents relate to another minor feature, namely simulating mouse inputs using non-mouse devices. The '853 patent misrepresented the state of the art at the time the patent was filed by stating that "a need exists for permitting a user to perform all operations of a mouse-type device using a stylus." This, however is demonstrably incorrect. The '536 and '853 patents were filed in November 2000. Long before that time, numerous systems had been developed that enabled computer users to simulate mouse behavior with touch input devices. For example, U.S. Patent No. 5,327,161 to Logan et al., entitled "System and Method for Emulating a Mouse Input Device with a Touchpad Input Device" (the "'161 patent"), was issued in 1994, years before the '536 and '853 patents were even filed. The '161 patent discloses a touchpad input device or touch-sensitive device that "can be used to replace the mouse cursor locator/input device in mouse-driven personal computers." (Col. 1, 11.18-20.) The touchpad in the '161 patent performs functions of a mouse. Further evincing the lack of inventiveness of the subject matter set forth in the '536 and '853 patents, the '161 patent noted that touchpad technology had been disclosed in patents that issued as early as 1978.... The '913 patent relates to storing input/output access factors in a shared data structure, and which clearly could not preclude the use of an entire operating system. The '913 patent specification is deficient with respect to a written description of the alleged invention and failes to provide sufficient detail for a person of skill in the art to make the subject matter of the claims. This deficiency renders the patent invalid, and in any event the claims do not cover the Nook and Nook Color devices to the extent the subject matter can be understood in light of the deficiencies. Tellingly, Microsoft was never able to fully explain how anything in the Nook and Nook Color related in any manner to the concepts set forth in the '913 patent. Neither product infringes the '913 patent. The above overview provides only a sampling of the triviality of the ten patents either mentioned in discussions by Microsoft prior to the filing of its lawsuits or asserted against Barnes & Noble in the litigations. This letter also has only provided examples of Barnes & Noble's many invalidity and non-infringement defenses to the patents asserted by Microsoft. All of these details throughout this letter point to the triviality of Microsoft's patents, with respect to both patentability and commercial applicability, particularly as these patents relate to the Android operating system. Please let me know if you would like further details in this regard. Very truly yours, [signature] Richard L. DeLucia Cc: Peter T. Barbur, Esq.

[address] Here's Exhibit E, an October 17, 2011 letter from Cravath's Peter Barbur to "Dear Gene", Gene Kimmelman, Chief Counsel for Competition Policy and Intergovernmental Relations at the US DOJ's Antitrust Division, and I note it's Cravath that points out that Stephen Elop was formerly a Microsoft executive while discussing the Microsoft/Nokia patent alliance made even more unholy by the MOSAID connection: EXHIBIT E [Cravath, Swaine & Moore letterhead] October 17, 2011 Microsoft/Nokia/MOSAID Dear Gene: Following up on our telephone call on Thursday, this letter provides some background concerning the recently announced horizontal agreement among Microsoft, Nokia, and MOSAID Technologies to license Nokia's wireless patents and split the proceeds. This is the latest in a series of tactics designed by Microsoft to raise its rivals' costs and prevent Android-based devices from taking away sales of Microsoft's Windows operating system. This description is based solely on publicly available information, and we suspect that nonpublic information relating to this agreement would be even more revealing. On September 1, 2011, MOSAID announced that it had reached an agreement to acquire Core Wireless Licensing S.a.r.l., a patent holding company that held 2,000 Nokia patents related to wireless communications standards and implementation. MOSAID stated that it made "no upfront payments" for the patents,1 and MOSAID reportedly received the patents for free.2 MOSAID then announced that it had also reached an arrangement with Microsoft and Nokia regarding the licensing of those patents. Specifically, MOSAID will be responsible for asserting the patents against manufacturers of mobile devices such as cell phones, and MOSAID will hand over to Microsoft and Nokia 2/3 of any licensing revenue it obtains.3 Thus Microsoft will share in the profits even though Microsoft does not appear to have contributed anything of value to the arrangement. ____________ 1 Press Release, "MOSAID Updates Shareholders On Special Committee Process, Addresses Wi-LAN Mischaracterizations", Sept. 12, 2011, http://www.mosaid.com/corporate/news-events/releases-2011/110912.php 2 Chris Velazco, "Mosaid Acquires 2,000+ Nokia Patents, Will Handle Licensing & Litigation For A Cut", Techcrunch, Sept. 1, 2011, http://techcrunch.com/2011/09/01/mosaid-acquires-2000-nokia-patents-will-handle-licensing-litigation-for-a-cut/ 3 Id. The parties are not shy about the power they think is afforded to them under the deal. In MOSAID's words, "the force of this [patent portfolio] is overwhelming",4 and 3G and 4G wireless telecommunications standards" practice the patents.5 MOSAID believes that "four of the top five global cell phone vendors" will soon require a license, and MOSAID is targeting "over a trillion dollars of unlicensed revenues" of mobile devices.6 MOSAID boasts that it is an aggressive licensor of its patents, noting that it achieved "complete saturation" of the DRAM market and "licensed all the DRAMs on the planet at one point".7 Because MOSAID is a "non-practicing entity" -- the euphemism for a patent troll -- the usual threat of counterlitigation for patent infringement will have no deterrent effect on its aggressive licensing plans. The deal is presumably related to Microsoft's horizontal agreement with Nokia, announced earlier this year, to coordinate their use of patents to drive out competitors. In February 2011, Microsoft and Nokia announced that Nokia would soon drop its Symbian operating system and instead adopt Microsoft's Windows Phone 7 as the operating system for its devices. The target of the agreement between Microsoft and Nokia is clear. As Nokia CEO (and former Microsoft executive) Stephen Elop stated shortly after announcing the deal, the "[n]umber one priority is to compete with Android."8 The new deal with MOSAID -- the negotiations for which began around the time the Microsoft-Nokia partnership was announced -- appears to be the mechanism by which Microsoft and Nokia will use Nokia's patents to attack Android devices. The MOSAID deal is further evidence of Microsoft's broader plan to shield itself from patent lawsuits while also eliminating competition from Android. Obviously, since Microsoft and Nokia are parties to and beneficiaries of the agreement governing MOSAID's patent assertion activities, MOSAID will not be going after Nokia phones or other products using Microsoft's mobile operating systems. Instead, as Microsoft and Nokia have made clear, the primary target is Android. MOSAID, as guided by Microsoft, will now be able to assert the Nokia wireless patents against Android devices that threaten Microsoft's business. ____________ 4 Interview, "John Lindgren, CEO of MOSAID talks magnitude of Nokia/Microsoft deal", Sept. 13, 2011,

Microsoft's attempts to direct how others enforce their patents are part of Microsoft's strategy of attempting to maintain its monopoly in PC operating systems by controlling and dominating the Android operating system. Android, which Google gives away for free, threatens Microsoft's traditional business model of licensing its proprietary operating system because OEMs no longer need to pay for a high-quality operating system. In addition, the open source Android operating system is superior to Microsoft's proprietary products. For those reasons, Android threatens Microsoft's core business. Application-rich Android devices such as tablets and smartphones now perform many of the functions once reserved for PCs, a trend that will reduce demand for PCs and PC operating systems, where Microsoft's Windows enjoys a powerful monopoly. Moreover, as operating systems such as Android become more popular, Android will become a viable candidate for adaptation to PCs, putting Android (and its companion, Chrome) into direct competition with Windows. Moreover, Microsoft has announced plans to run its flagship Windows operating system on tablets, and the popularity of Android-based tablets threatens the dominance of Windows. In response to these competitive threats, Microsoft is embarking on a campaign of asserting trivial and outmoded patents against manufacturers of Android devices. Microsoft demands exorbitant licensing fees (similar to the fee for the entire Windows Phone 7 operating system) and imposes licensing conditions that restrict manufacturers' abilities to upgrade and improve their products with features consumers want. Microsoft is attempting to raise its rivals' costs in order to drive out competition and to deter innovation in mobile devices. Microsoft's arrangement with MOSAID and Nokia, in conjunction with its improper use of its own patents, is causing and will continue to cause serious harm to competition. Microsoft's conduct will raise costs to consumers, reduce the quality of popular goods, and impede innovation in a technology-rich market. Microsoft's conduct poses serious antitrust concerns and warrants further exploration by the Department of Justice. Very truly yours, [signature] Peter T. Barbur Gene I. Kimmelman, Esq.

[address] VIA ELECTRONIC MAIL AND FIRST-CLASS MAIL If any of you could help me with text of Exhibit F, I'd appreciate it a lot, because otherwise, it's all hand typing on my part, and I'm tuckered out. I think it's important to present everything, and I'll definitely do it if no one else is in a position to help out. Personally, I view this as one of the most intriguing developments in a long time. I've long been writing that I thought there ought to be an antitrust case to be made, but I'm no expert in that area of law by any means, and yet here it is. Cravath, Swaine and Moore *are* experts in antitrust, and the fact that they are representing Barnes & Noble now, along with other outside firms like Kenyon & Kenyon, is significant to me. Update: We have now finished one-half of Exhibit F, the report by an expert, Timothy J. Bresnahan, who says that Microsoft has been unable to compete in the mobile space, and so as an alternative made the deal with the devil Nokia apparently to attack competitors with trivial and outmoded patents. You will likely take it as proof that there is a God that he uses a FOSSPatents' article as evidence against Microsoft, in footnote 28: EXHIBIT F White Paper of Timothy J. Bresnahan I. Introduction and Overview of Conclusions. I have been asked by Barnes & Noble, Inc. ("Barnes & Noble") to provide an opinion as to Microsoft's current conduct with respect to mobile operating systems. I have based my analysis on publicly available evidence and representations made to me by Barnes & Noble. Further, I have relied on my prior knowledge about competition in operating systems, mobile devices and personal computers from over twenty years of studying the industry and, particularly, my study of and familiarity with Microsoft's pattern of anticompetitive conduct. Based on my extensive policy and academic experience in applying economics to antitrust analysis under both U.S. and EU law, including my prior work analyzing Microsoft's conduct in connection with its PC operating systems monopoly, this white paper offers the following conclusions: Mobile operating systems, including those used for smartphones, e-readers and tablets, pose a competitive threat to Microsoft's monopoly in PC operating systems.

Microsoft's current conduct in asserting against Barnes & Noble patents that I am informed are trivial and outmoded is anticompetitive and appears to be part of a larger Microsoft campaign against the open-source Android mobile operating system.

Microsoft's current conduct with respect to mobile operating systems, particularly its anticompetitive conduct against Android, parallels its prior anticompetitive response to threats from competing operating systems (e. g., DR-DOS) and Internet technologies (e. g., Java and Netscape). II. Qualifications. My opinion is based on my extensive policy and academic experience in applying economics to antitrust analysis under the U.S. and EU laws. In particular, from 1999 to 2000, I was Deputy Assistant Attorney General and Chief Economist, Antitrust Division, U. S. Department of Justice. I am currently the Landau Professor in Technology and the Economy and Professor of Economics at Stanford University, and a Senior Fellow at the Stanford Institute for Economic Policy Research (SIEPR). At SIEPR, I have served as the Director of the Center for Employment and Economic Growth, the Director of the Technology and Economic Growth Program, and the Gordon and Betty Moore Senior Fellow. I was one of the founders of, and later the leader of, the Stanford Computer Industry Project. I am also a Senior Fellow at the National Bureau of Economic Research and participate in the Productivity and Industrial Organization Programs that study technical progress and competition. I have been elected as a Fellow of the American Academy of Arts and Sciences, as a Fellow of the Econometric Society and as a Vice President of the American Economics Association. My areas of specialization include Industrial Economics, particularly the economics of high technology industries. I have had particular specializations in the uses of computer systems in large organizations, in the commercialization of computer systems, and in the analysis of competition and of competition policy. I have written books, book chapters, and peer-reviewed articles on the economics of technological change and competition in high technology industries. A number of these publications examine Microsoft's competitive conduct.1 III. Microsoft Has Failed to Compete Effectively in Mobile Operating Systems. Microsoft has failed to compete effectively in mobile operating systems. As I explain below, it has failed to deliver a competitive product to consumers and has not been a leader in the innovation process for mobile operating systems. As a result, it has missed a profitable business opportunity and now faces a potentially serious threat to its monopoly in PC operating systems. A. Overview of Mobile Operating Systems. Mobile operating systems are used on a variety of devices, including smartphones, e-readers and tablets. Smartphones are high-end mobile phones with computing capability. Operating systems for these devices are supplied primarily by Microsoft, Apple, Google, Palm and Nokia. An e-reader is a portable electronic device designed primarily for reading digital books and periodicals, and is similar in form to a tablet computer. Examples include the Amazon Kindle and the Barnes & Noble Nook products. E-readers use operating system software supplied by Google, Microsoft, and providers of the open-source Linux operating __________

A selected list of my publications related to Microsoft and competition is attached hereto as Appendix A. 2 system. Tablets are mobile devices that offer display screens of 7 to 12 inches and run a mobile or desktop operating system. Examples include the Apple iPad, Motorola Xoom, Blackberry Playbook, Dell Streak, and Samsung Galaxy.2 Tablets use operating systems supplied by Apple, Google, Research in Motion, Nokia, and others. The direct customers for iOS, Android, Windows Phone 7 and other mobile devices are the mobile device manufacturers ("original equipment manufacturers" or "OEMs") that decide which operating systems to use for the devices they sell. All of these mobile operating systems also compete for adoption by end-users who choose which mobile device to purchase based in part on the operating system. The structure of the mobile operating system marketplace is somewhat unusual. The leading company, Apple, is vertically integrated into hardware. This does not mean it is not a meaningful competitor for end-users of mobile systems. It means only that it does not rely on independent OEMs to put its software together with hardware and distribute the resulting product to end-users. Another leading supplier of mobile operating systems, Google, gives away its Android product to OEMs. The very attractive price at which Android is available to OEMs is one reason it has been so widely adopted. Microsoft's primary business model has been to sell its mobile operating systems to OEMs, the same business model it has used in selling its PC operating system. Although these OS suppliers have pursued different business models, they have nonetheless been the leading competitors in mobile operating systems. Google and Apple have been successful competitors. Microsoft, in contrast, has not. B. Microsoft Has Failed as an Innovator in Mobile Operating Systems. To date, Microsoft has not been an important innovator in mobile operating systems. It has lagged behind Apple and Google in smartphones and has been strikingly uncompetitive in the tablet and e-reader segments. ________________

Given the recent emergence of tablet devices, industry analysts offer conflicting definitions, and some distinguish between media tablets such as the iPad and tablet PCs that run a full desktop operating system. See IDC press release, "IDC forecasts 7.6 Million Media Tablets to be Shipped Worldwide in 2010," May 20, 2010, http://www.idc.com/getdoc.jsp?containerId=prUS22345010.

Microsoft Has Failed to Compete Effectively in Smartphone

Operating Systems. Microsoft has a weak position in smartphone operating systems because it has not delivered a compelling product that can compete effectively with the operating systems offered by Apple and Google, among others. Both hardware (the handset) and the operating system affect the quality of the phone as experienced by the user. Apple has extended its business model used in PCs and iPods of combining striking hardware and a user-engaging operating system to create the very successful iPhone it introduced in 2007. Using this model, Apple had gained a 25% share of the U.S. smartphone installed base by December 2009,3 and had become the world's largest smartphone vendor by revenue in the first quarter of 20114 Sales of smartphones based on the Android operating system, introduced a year later than the iPhone, were propelled by a different, but also successful business model. Google has organized the supply of its mobile operating system to function as a public good. It offers its operating system free of charge on an open-source basis to OEMs, imposes no restrictions on the use of the operating system, and requires that users who improve the product make those improvements available to others. This approach has been attractive to OEMs. In 2008-2009, Android-based smartphones were launched by HTC, Samsung, Motorola and LG, among others.5 Despite entering the market more than a year after the iPhone, sales of Android-based smartphones surpassed sales of Apple's iPhone in the second quarter of 2010 in the United States.6 In the spring of 2011, industry experts were predicting that Android devices would account for nearly 50% of worldwide smartphone unit sales by 2012.7 ___________________

Much of the share gain came from sales to the rapidly expanding consumer base of smartphone users and some came by winning enterprise sales from RIM's Blackberry product line.

Unit sales of smartphone operating systems have grown by 34%.8 Sales of smartphones with the Apple or Google operating system account for most of this growth. Indeed, smartphones running iOS or Android grew from virtually nothing in 2007 to 35% of unit sales of smartphone operating systems in 2010.9 Despite the rapid growth in smartphone sales, sales of phones based on operating systems supplied by Microsoft have languished. Microsoft's primary business model in smartphone operating systems has been based on selling its OS to handset makers, and it has been successful in attracting OEMs. In 2008-2009, OEMs that offered Android-based phones generally offered handsets based on Windows as well. For example, HTC, LG, Samsung, Toshiba, and ZTE all offered phones running the Windows Mobile operating system.10 Nonetheless, the worldwide market share held by Windows-based smartphones declined from 12% in 2007 to 4.2% in 2010, and 2010 worldwide unit sales were below unit sales in 2007.11 Consumers have clearly preferred to purchase phones based on the Android platform when given a choice between the Android and Microsoft operating systems from the same handset manufacturer. Microsoft has failed to compete effectively because it has failed to offer a product that can compete with the offerings of Apple and Google. In February 2007, the year the iPhone was released, Microsoft released a new version of its smartphone operating system, Windows Mobile 6.12 The product contained a number of serious deficiencies, including weak support for touchscreens, applications that required use of a stylus rather than a finger, and a poor mobile ____________________

In the interim, handset manufacturers reduced or dropped support for Windows Mobile and turned to other operating systems, primarily to Android.15 Microsoft's record of failures in mobile operating systems extends to its "social phone" handset product, the Kin, which Microsoft introduced in April 2010.16 Targeting heavy users of social networks, the Kin relied on technology acquired from Danger, producer of the popular Sidekick phone. "Microsoft invested nearly two years in developing the Kin, but pulled it from the market a mere 48 days after the product launch after selling fewer than 10,000 units. Industry analysts described the product as "an absolute failure" and "a mistake from the get-go.18 Microsoft CEO Steve Ballmer has acknowledged Microsoft's costly missteps in mobile operating systems. He admitted in 2009 that Microsoft had "screwed up with Windows Mobile," and wished that Windows Phone 7 had already been launched.19 He characterized an interim 2009 release of Windows Mobile 6 as "an unwanted stopgap."20 And he stated in a 2010 Wall _________________

Phones running Symbian fell from 63.5% of worldwide unit sales in 2007 to 37.6% in 2010, 23 and market observers recently predicted that Symbian would yield its market-share lead to Android in 2012. 24 Under the terms of the deal, Microsoft paid Nokia more than $1 billion to launch the partnership. Nokia in turn will pay Microsoft a per-handset fee for the use of Windows Phone 7. 25 The Nokia alliance may allow Microsoft to compete more effectively with Apple and Google. Analysts now predict that Microsoft Phone will be the second-largest mobile operating system by 2015. 26 Microsoft has also recently announced agreements with ZTE, Acer, and Fujitsu under which their handsets will run the Windows Phone mobile operating system. 27 Whether consumers will choose to buy smartphones with a Microsoft operating system because the handset is offered by Nokia or these other OEMs remains an open question. __________________

The companies have announced that they intend to use their patents in a joint offensive effort against "infringing" users,28 suggesting that the deal was motivated by a strategy of forming an offensive patent pool. There are pro-competitive reasons for forming a patent pool. Often, however, a patent pool can have anticompetitive effects. Sorting the pro-competitive from the anticompetitive requires a careful investigation of why the patents would be more valuable used together than they would be used independently. Because Microsoft and Nokia have made public statements that they intend to use their patents offensively, and because Microsoft has targeted Android, which it deems its primary competitor, this arrangement raises antitrust concerns that warrant investigation.29 2. Microsoft Has Failed to Compete Effectively in Tablets. Microsoft is currently even less competitive in tablets despite more than a decade of investment in operating system software for tablet computers. Just as with smartphones, the fact that Microsoft is not an important player in tablet computing can be traced to its failure to provide innovative, compelling products to consumers. The tablet computer is not a new idea. Indeed, Microsoft, imitating earlier tablet offerings by GO and others that built on the tablet concept suggested by Alan Kay in 1968, first proposed development of a tablet PC in 2000.30 Microsoft's efforts, however, have failed to make it a player in this segment. Tablet PC products based on the Windows operating system have had little marketplace success outside specific, narrow niches such as transportation and healthcare.31 One industry analyst observed in 2010 that Microsoft's efforts to deliver a tablet _______________

The iPad is ideal for browsing the web, playing music, looking at photos and videos, playing games, and reading e-mail, all through a finger-based touchscreen user interface. Apple has not attempted to replicate a mouse-and-keyboard, desktop-based user interface in a smaller form factor - a failed strategy that Microsoft attempted with its Tablet PC and UMPC. The iPad does not run the Mac software Apple uses on its PCs nor does it perform the business-oriented tasks traditionally associated with PC computing. It is, in short, not just a small computer, as Steve Jobs insisted in a recent public appearance.38 Apple sold 14.7 million units in 2010, and 9.3 million units in the ___________________

Gartner Group estimates sales of 47.9 million iPads in 2011.39 Rival device manufacturers are scrambling to manufacture competing tablet devices. By one count, more than 60 different manufacturers will introduce competing products in 2011.40 A variety of hardware manufacturers, including Acer, Asus, Dell, HTC, LG, Motorola, Samsung, and Toshiba, have adopted Google's Android operating system as the platform for competing media tablets they plan to ship in 2011.41 Gartner Group estimates that by 2012, Android-based tablets will capture 25% of media tablet sales, while other mobile operating systems, including QNX (Research in Motion), WebOS (Hewlett-Packard), and MeeGo (Nokia), will claim approximately 12% of sales. Notably, Microsoft is not mentioned in Gartner's tablet sales forecast. Microsoft is reportedly planning to release a new operating system dedicated to media tablets in the fall of 2012, but has not formally announced its plans to do so.42 A fall 2012 release would put Microsoft two years behind Apple. Microsoft has announced that Windows 8 will run on the low-power ARM chips found in many media tablets and smartphones available today.43 In addition to general-purpose media tablets such as the iPad and Samsung's Galaxy, more specialized devices that substantially overlap with tablet functionality have been a commercial success in the marketplace for some years. Amazon's Kindle e-reader was introduced in November 2007, and was quickly followed by a number of e-reader products from other vendors, including Barnes & Noble. These devices run on Android, Linux, and Microsoft __________________

When introduced, these devices were narrowly targeted as readers for electronic books, but manufacturers are adding a wider set of capabilities to follow-on products. For example, an updated version of Barnes & Noble's Nook Color released in April 2011 includes e-mail, support for Adobe Flash, and downloadable Nook apps and has been described as an iPad competitor and a "tablet in e-reader clothing."45 These changes make the e-reader a closer substitute for tablet computers. C. Mobile Devices Present a Nascent Threat to Microsoft's Monopoly in PC

Operating Systems. Mobile devices represent a clear, if nascent, competitive threat to Microsoft's Windows PC monopoly. This threat is currently particularly significant for individual users. Consumers who use their PCs primarily for email, Internet access and media now have increasingly good substitutes that do not rely on Microsoft operating systems. Tablets, for example, are attractive compared to PCs because they deliver "a richer experience around content consumption," and offer desirable characteristics for users engaged in social networking. For users who particularly value mobility, tablets and smartphones offer reduced power consumption, all-day battery life, and lighter weight. Tablet computers are the mobile device most similar to PCs, but the extent to which users rely on smartphones for search, email access and other "PC-like" functions implies that these devices also have the potential to reduce demand for PCs. Mobile devices are unlikely to replace the personal computer in the short run, but analysts note that tablets are already serve as a substitute for some PC users. A Nielsen survey of tablet owners found that 32-35% of tablet owners who also own a PC reduced their PC use after purchasing a tablet. Further, 77% of tablet owners used tablets for tasks they would have previously performed with a laptop or desktop computer. ___________________

Within the PC segment, mobile PCs for consumers have led PC sales growth over the past five years,46 but growth in this segment fell during the first quarter of 2011 while tablet sales surged.47 Acer, the industry's leading supplier of netbook computers -the "nearest neighbor" among PCs to tablet computers - has been particularly hard hit. Its U.S. unit shipments fell 42% in the U.S. and 16% globally in the first quarter of 2011, and Acer's management has publicly identified tablets as the cause.48 Microsoft's failure to innovate successfully in mobile operating systems has meant that it has been unable to take advantage of a growth opportunity. With its failure to compete effectively in mobile operating systems, Microsoft has not only missed a profitable business opportunity but has given rivals and new entrants an opportunity to challenge its Windows PC monopoly. IV. Microsoft's Current Conduct in Asserting Patents Against Barnes & Noble Appears

to be Anticompetitive and Part of a Larger Campaign Against the Open-Source

Android Operating System. Unable to compete in mobile operating systems and observing the success of competing systems that have the potential to undercut its monopoly in PC operating systems, Microsoft is apparently now engaging in an "industry-wide" patent offensive against the Android operating system. I understand that Microsoft contacted Barnes & Noble in early 2010 to discuss "patent issues" relating to Barnes & Noble's Nook products. Microsoft alleged that Barnes & Noble Nook and Nook Color e-readers infringed certain Microsoft's patents. During that discussion and in subsequent discussions between Microsoft and Barnes & Noble, I am informed that Microsoft claimed that its patents allow it to control the entire Android operating system. In addition, Microsoft insisted that Barnes & Noble sign a non-disclosure agreement ("NDA") to ______________

Further, based on representations from Barnes & Noble, the licensing agreement that Microsoft proposed to Barnes & Noble limited, restricted or entirely eliminated Barnes & Noble's ability to upgrade or improve its Nook products. Indeed, Barnes & Noble describes the proposed licensing agreement as prohibiting it from incorporating innovative features into its Nook products, features unrelated to the patents at issue, without negotiating a new license fee with
