Minecraft is an incredibly popular block-building game that has taken over the gaming community. This fame, however, comes at a price. Namely, a patent troll has targeted the indie game for a shakedown. Patent trolls are one of the scourges of our times, a company or person who uses a broad patent to attack generally smaller businesses in hope of a payout under threat of costly legal action. As patent laws around software are, shall we say, behind the times, patent trolling has become a danger to anyone who makes games or software in general. Notch, the man behind the mines, has vowed to fight the troll. Boing Boing has the story.
