I’m pleased to announce that Microsoft is joining the Open Invention Network (“OIN”), a community dedicated to protecting Linux and other open source software programs from patent risk.

We know Microsoft’s decision to join OIN may be viewed as surprising to some; it is no secret that there has been friction in the past between Microsoft and the open source community over the issue of patents. For others who have followed our evolution, we hope this announcement will be viewed as the next logical step for a company that is listening to customers and developers and is firmly committed to Linux and other open source programs.

Since its founding in 2005, OIN has been at the forefront of helping companies manage patent risks. In the years before the founding of OIN, many open source licenses explicitly covered only copyright interests and were silent about patents. OIN was designed to address this concern by creating a voluntary system of patent cross-licenses between member companies covering Linux System technologies. OIN has also been active in acquiring patents at times to help defend the community and to provide education and advice about the intersection of open source and intellectual property. Today, through the stewardship of its CEO Keith Bergelt and its Board of Directors, the organization provides a license platform for roughly 2,650 companies globally. The licensees range from individual developers and startups to some of the biggest technology companies and patent holders on the planet.

Joining OIN reflects Microsoft’s patent practice evolving in lock-step with the company’s views on Linux and open source more generally. We began this journey over two years ago through programs like Azure IP Advantage, which extended Microsoft’s indemnification pledge to open source software powering Azure services. We doubled down on this new approach when we stood with Red Hat and others to apply GPL v. 3 “cure” principles to GPL v. 2 code, and when we recently joined the LOT Network, an organization dedicated to addressing patent abuse by companies in the business of assertion.

At Microsoft, we take it as a given that developers do not want a binary choice between Windows vs. Linux, or .NET vs Java – they want cloud platforms to support all technologies. They want to deploy technologies at the edge – on any device - that meet customer needs. We also learned that collaborative development through the open source process can accelerate innovation. Following over a decade of work to make the company more open (did you know we open sourced parts of ASP.NET back in 2008?), Microsoft has become one of the largest contributors to open source in the world. Our employees contribute to over 2000 projects, we provide first-class support for all major Linux distributions on Azure, and we have open sourced major projects such as .NET Core, TypeScript, VS Code and Powershell.

Now, as we join OIN, we believe Microsoft will be able to do more than ever to help protect Linux and other important open source workloads from patent assertions. We bring a valuable and deep portfolio of over 60,000 issued patents to OIN. We also hope that our decision to join will attract many other companies to OIN, making the license network even stronger for the benefit of the open source community.

We look forward to making our contributions to OIN and its members, and to working with the community to help open source developers and users protect the Linux ecosystem and encourage innovation with open source software.
