Troll Proofed. Innovation Protected.

The Defensive Patent License (DPL) is a new legal mechanism to protect innovators by networking patents into powerful, mutually-beneficial legal shields that are 100% committed to defending innovation – no bullies, trolls, or other leeches allowed. It also helps prevent these actors from patenting open technologies and pulling them out of public use. It's a way for patents to be used for good, and support innovators instead of threatening them.
