Patent licensing company Lodsys has extended its legal case against several high-profile smartphone developers to include Rovio, EA, Take-Two, Square-Enix and Atari.
The continuing action is part of claims relating to two patents owned by Lodsys: U.S. Patent No. 7,620,565 and U.S. Patent No. 7,222,078. Lodsys claims that each of the 11 defendants now involved in the case has infringed those patent filings.
The games which have been added to the case, as reported by Foss Patents, are Angry Birds for iOS and Android, Atari's Greatest Hits for iPad and iPhone, Square Enix: Big Hit Baseball for iPhone and iPad, The Sims 3 for iPhone and the iPhone version of NHL 2K11.
Previously Lodsys' efforts had been concentrated primarily on iOS developers, prompting Apple to argue that its own licences covered its developers.
Whilst Apple's posited legal intervention failed to stall Lodsys' advances, the company has now increased its scope to include more Android targets. Google has so far remained tight-lipped on the matter.
