Federal Circuit OKs PTAB invalidating patent claims prior litigation confirmed as valid
Patent claims being adjudicated valid in federal district court and then being killed in an administrative proceeding at the PTAB is exactly the problem so many of us saw coming. Time and time again throughout the debates in Congress, and all through the legislative history, post grant proceedings were explained as being a faster, low-cost alternative to litigating validity disputes in Federal District Court. That was just a lie. Post grant proceedings at the PTAB are not cheap, and they are not an alternative to district court proceedings. The PTAB is duplicative and anti-patent. In fact, because of the different standards used between district courts and the PTAB, and because district courts presume patents are valid pursuant to 35 U.S.C. 282, different outcomes are practically inevitable.
