Entrepreneur Mark Cuban and Markus “Notch” Persson, the developer of the popular videogame Minecraft, announced Wednesday they are donating a combined total of $500,000 to the Electronic Frontier Foundation to help protect innovation and reform the system for software patents. And they’re backing up the money with a dose of sharp humor.

Cuban, the owner of the Dallas Mavericks and an outspoken critic of the U.S. patent system, stipulated that some of his $250,000 donation be used to fund the EFF staff attorney position that oversees intellectual property issues—currently held by staff attorney Julie Samuels—and specified that the funded position be called, “The Mark Cuban Chair to Eliminate Stupid Patents.”
