Yes, complete with spelling mistake and all. The Texas-based company Uniloc are taking Mojang to court over a software patent infringement – specifically, that the Android version of ‘Mindcraft’ infringes on claim 107 of patent #6,857,067.
That claim is for a “system and method for preventing unauthorized access to electronic data [covering] executable computer code on an electronic device to prevent unauthorized access to electronic data stored on the electronic device” which is, as you might appreciate, pretty vague.
The company is also suing Halfbrick, Gameloft, Square Enix and EA, and in the past has sued Activision, Sony, and Microsoft, among others, for various similarly-vague-sounding patent infringements. Notch has described software patents as “plain evil” and promised to “throw piles of money” at the suit to “make sure they don’t get a cent”.
