Uniloc USA Inc, and Uniloc Luxembourg S.A. have today filed a lawsuit in the Eastern District Court of Texas against Minecraft maker Mojang, asserting patent infringement of US Patent 6857067.

The patent in question essentially appears to cover just about all forms of DRM and targets Minecraft on Android devices, as these devices call home to see if they’re authorised to run, and that’s a big no-no according to this patent.

A full copy of the complaint is here, where you can see that the filing erroneously calls the allegedly-infringing product “Mindcraft” instead of “Minecraft.”

The fact that they cannot even get the name of the software they’re suing over right doesn’t speak highly of a professional approach in my opinion.

Markus “Notch” Persson tweeted, “Unfortunately for them, they’re suing us over a software patent. If needed, I will throw piles of money at making sure they don’t get a cent. … Software patents are plain evil. Innovation within software is basically free, and it’s growing incredibly [rapidly]. Patents only slow it down.”
