Skillz alleges that Papaya misrepresented its games by using bots, which created unfair competition and caused damages amounting to hundreds of millions of dollars. Skillz's attorneys argue that the company's financial decline is directly linked to Papaya's actions, claiming that had Papaya disclosed its use of bots, it would not have been able to capture Skillz's customers and market share.
Gramm v. Deere & Company, No. 2024-1598 (Fed. Cir. Mar. 11, 2026), involves neither obviousness nor the Graham factors. Instead, it offers an illustration of means-plus-function claiming under § 112(f) and the doctrinal hazards.
The enormity of the problem cannot be understated. A Federal Circuit panel recently reached a final decision that, if not overturned, will destroy the U.S. patent system, and will ironically impact the most valuable patents disproportionately. The ruling was simple and continues a disturbing and inexplicable trend-a patent issued after more than six years in prosecution is presumed unenforceable as the result of prosecution laches.
U.S. Patent No. 9,491,542 is titled "Automatic Sound Pass-Through Method and System for Earphones" and was challenged by Samsung via inter partes review (IPR) after ST1 sued Samsung for infringement. Samsung argued that claims 1-10 and 13- 20 of the patent were invalid due to obviousness based on three prior art references: Rosenberg, Ichimura and Visser. The PTAB ultimately found all of the challenged claims obvious over combinations of the prior art, but also found unchallenged claims 11 and 12 unpatentable without explanation.
The case centers on the "Martin" reference, a patent application covering LED technology that was filed on April 16, 2003 and published on October 21, 2004. Martin was later abandoned and never became a patent. Lynk Labs' '400 patent claims a priority date of February 25, 2004, placing it squarely in the gap between Martin's filing and publication dates. Samsung successfully used Martin to challenge claims of the '400 patent as obvious in IPR.
This week on IPWatchdog Unleashed, I speak with Todd Walters, who is Chair of the Patent Office Litigation practice group at Buchanan.

We reflect on the intensity of opinion from patent owners and petitioners and discuss the high financial stakes and strategic importance of America Invents Act (AIA) proceedings.
