US Patent & Trademark Office Board of Appeals and Interferences finds that claims for a novel & nonobvious card game that could be played in a casino do not recite patent-eligible subject matter, applying Supreme Court decision of In re Bilski (June 2010). The U.S. had been the only patent-granting jurisdiction protecting card games. This case considers such claims to be merely for an abstract idea and hence not patent-eligible under 35 U.S.C. 101. Implicitly it calls into doubt existing U.S. patents for games licensed to casinos in Las Vegas, Atlantic City etc. as well as other patents on games.
