The Defensive Patent License (DPL) is a patent license proposed by Jason Schultz and Jennifer Urban, directors of the Samuelson Law, Technology & Public Policy Clinic at the University of California, Berkeley as a patent licensing equivalent of the GPL copyright license.[1][2][3] It requires entities licensing their patents under the DPL to license all of their patents under the DPL, with free licenses granted to all other DPL participants.[4] DPL participants remain free to launch patent lawsuits against non-participants.
