With 6 lawsuits, 32 preliminary injunction actions, and over 20 PTAB proceedings, GREE and Supercell have been duking it out in the IP world, with millions of dollars in legal fees being spent in the process.[1] Most recently, the PTAB denied Supercell’s PTAB challenges to GREE patents in early September, while an Eastern District of Texas lawsuit went to verdict and found in favor of GREE on September 18th, awarding $8.5 million dollars in damages to GREE.[2]

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.

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.

The Patent Trial and Appeal Board (PTAB) recently upheld the patentability of a video game-related patent, ruling the computer graphics features were not obvious over the prior art. The patent (US Patent 7,061,488) address techniques for rendering lighting and shadows in computer graphic simulations where there are at least 2 virtual light sources. The claims were alleged to be obvious because the high level concepts were allegedly known in the art as evidenced by various prior art references. However, the PTAB disagreed stating that there was no evidence that it would have been obvious to combine the prior art features. This case shows that even if general concepts are known, improvements to those concepts and/or a unique combination of concepts can be patentable.

The Federal District Court in Delaware recently denied a motion to dismiss a patent infringement case involving a video game networking technology patent based on the patent allegedly being  invalid for lack of patent-eligible subject matter under 35 U.S.C. § 101. Despite all of the recent press regarding the so-called Alice test, which revised the test for patent-eligible subject matter, video game related patents are still obtainable and enforceable. It is critical that patent applications for these inventions be carefully considered, the patent applications be properly drafted and the claims be presented in a way that complies with the relevant test.
