Creator Markus 'Notch' Persson, known for his sense of humor, has already responded to the filing: "Step 1: Wake up. Step 2: Check email. Step 3: See we're being sued for patent infringement. Step 4: Smile. 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."
Uniloc's patent, awarded back in 2005, is for a system "preventing unauthorized access to electronic data" between a portable device and a license registration authority. Uniloc has long claimed they have rights to all software that verify licensing on the Android OS.
Notch says Minecraft does not perform licensing checks in any manner similar to the patent.
