Texas based Lodsys has sued Finland based games developer Rovio Mobile, creator of well-known mobile phone game, Angry Birds over a patent infringement issue.
Lodsys has filed an amended complaint with the US District Court for the Eastern District of Texas including Ravio Mobile, which names a number of other games makers including Atari, EA, and Take-Two Interactive.
Lodsys owns patents granted between 1999 and 2009, and first filed claims against seven defendants last May.
The company has now dropped its claims against one of those companies, Wulven Games, but added Rovio’s versions of Angry Birds for iPhone and Android, as well as EA’s The Sims 3 for iPhone, Atari’s Greatest Hits compilation for iPhone and iPad, Square Enix’s Big Hit Baseball for iPhone and iPad, and Take-Two Interactive’s 2K Sports NHL 2K11 for iPhone.
The patent licensing company has said that Rovio and other developers violated its patents with games on Apple’s iOS platform and Google’s Android.
In its July 21 filing before the court, Lodsys claims Rovio has infringed patents 7,620,565 and 7,222,078.
Rovio chief executive Mikael Hed was quoted saying Wall Street Journal saying that the company has not received any notification from Lodsys so it cannot comment on it.
Rovio marketing chief Peter Vesterbacka said last week that the game had surpassed 300 million downloads.
