Why Do We Assume Patents Are Valid When Patent Office's Own Numbers Show They Get Things Wrong All The Time?

Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community. Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis. While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

One of the bizarre things about the patent system is the "presumption of validity," in which a patent officially has to be presumed valid . Conceptually, this makes very little sense. Patents grant a pretty broad monopoly on "inventions" for an extended period of time... based entirely on approximately 18 hours that a patent examiner has to spend looking over the thing. Do we really think that a patent examiner gets things right most of the time? It seems that even the US Patent Office'sshows that's simply not true. A friend pointed me to the USPTO's recently released data concerning re-exams (pdf and embedded below), which demonstrates in great detail why patents shouldn't be presumed valid. Basically, the data suggests that an awful lot of patents were handled poorly.The document notes that 92% of re-exam requests are granted -- meaning that nearly all re-examination requests lead to a re-examination by the Patent Office. So, if most patents were well constructed in the first place, you would imagine that most of them would come through the re-examination process unscathed with no changes, right? Only if patent examiners were really bad at their jobs would a large percentage of patents need to be changed or rejected completely on re-exam. Given the "presumption of validity" that grants a monopoly, and the massive dollar amounts that patents sell for and are able to extract in settlements, you'd think that re-examined patents must normally confirm the original diagnosis. Hell, given that information, I'd hope thataround 95% of patents, having passed the approval process, would be solid enough to survive the re-exam process untouched.If the number was below 90%, I'd think the system was in trouble and needed some fixing. If it was below 70%, I'd think that we should be declaring the system a failure. If it was below 50%, I'd be questioning the entire basis of the patent system. So what is it?Would you believe that only22%! That means that 78% of all patents that are granted a re-exam hadwith their original claims -- and remember, 92% of re-exam requests are granted. All these patents were initially approved and enjoyed the presumption of validity, which. This isn't just a failing grade. This is an. It's true that 67% of the re-examined patents still are allowed with "claim changes", and only 11% are completely rejected, but those numbers are little comfort when we're told that we need to presume all of the claims in all patents are perfectly valid.Now, some might claim that this number is perfectly fine, because only bad patents get re-exam requests. In fact, you could argue that perhaps these numbers show the system is working in that bad patents get re-exam requests and good patents remain valid. But there's little to no evidence to support that. Already, those who dislike patent re-exams are claiming that patent re-exams are abused with too many good patents getting re-examined. So it certainly appears that all sorts of patents get re-examined... and a very large percentage of them appear to turn out to have been mistakenly granted.This highlights, in pretty stark contrast, just how brokenthe system is. For a system like this to be valid, it should be. It needs to be based on objective information, not the random subjective opinions of a particular examiner. Yet the data suggests that's exactly what's happening, meaning that we're handing out hundreds of thousands of monopolies based on the mere whims of patent examiners, who haven't been shown to be even remotely consistent, and who have very little time to actually examine what it is they're granting monopolies over.How doesconsider that to be a reasonable system?
