System art is of increasing importance in patent disputes despite being frequently overlooked or “left for later” in many cases.  A recent decision in the Ironburg Inventions v. Valve Corp. case highlights the importance of system prior art, particularly as IPR success rates have dropped from their high points in 2012-15.

In two decisions recently designated as “precedential,” the PTAB rejected two theories raised by petitioners for why the service of a complaint should not trigger Section 315(b)’s one-year time bar for filing a petition. In the first case, the Board rejected the petitioner’s argument that a complaint must be served by a plaintiff that has standing to assert the patent. In the second case, the Board rejected the petitioner’s argument that the service of the complaint must effect personal jurisdiction. Both case results stem from the Federal Circuit’s decision in Click-to-Call Technologies, L.P. v. Ingenio, Inc., where the court held that the plain and unambiguous meaning of Section 315(b)’s time bar merely requires the service of a complaint allege patent infringement, and thus leaves little room for finding exceptions to the time bar’s application.

Last fall, the PTAB modified its procedures for IPR claim construction, eliminating the use of the broadest reasonable interpretation standard. Since the rule change last year, companies challenging the validity of patents at the PTAB are required to use the Phillips plain and ordinary meaning standard.

It is very common to defend against a claim of patent infringement by litigating in the district court and the PTAB in parallel. The most straightforward-way for the defendant to win is to persuade the PTAB that the asserted patent is invalid. But, that is becoming more difficult as Director Iancu pushes the PTAB to apply greater scrutiny to petitions in order to address patent owner criticism that the PTAB proceedings are unfair. However, a recent decision disposing of a non-practicing entity’s long-running litigation against Ubisoft highlights how a defendant that ultimately lost on an issue before the PTAB can use the loss to their advantage in district court.

In a proceeding that included Patent Office Director Andrei Iancu on the panel, the PTAB issued an order this past week denying institution of 3 IPRs filed by Valve. The decision demonstrates that the PTAB continues to tighten its standards for institution of post-grant challenges, including based upon considerations related to what it perceives as fairness to patent owners.

Video game patents being asserted in litigation are frequently challenged by defendants at the Patent Trial and Appeals Board by filing a petition requesting inter partes review (IPR), post-grant review (PGR), or (less frequently) covered business method review (CBM). Gaming companies need to be cautious in preparing these petitions as the PTAB continues to increase its scrutiny of petitions and is showing a reluctance to “fill in the dots” for deficient petitions.
