FOSSPatents reports that the patent trolls over at Lodsys have just upped the ante: they have just sued five more iPhone application makers over their use of in-app-purchases. These five new companies include major game makers like Rovio, the gang behind the widely popular Angry Birds game, Electronic Arts (EA), Atari, Square Enix, and Take-Two-Interactive.

EA was sued over the use of in-app-purchases in their game Sims 3 for iPhone, Atari was sued over their ‘Greatest Hits’ iOS application, Square Enix was sued over Big Hit Baseball for iPhone and Big Hit Baseball for iPad, and Take-Two was sued over their very popular NHL 2K11 for iPhone. These new lawsuits demonstrate that Lodsys is not afraid to attack big names like EA and Rovio, and this trend is seemingly not coming to an end even though Apple has stepped in.
