What this entry documents is not a solution.
This practice may be ineffective or useless in the long term.
ESP's position is that abolition of software patents is the only solution.
The Defensive Patent License (DPL) is a proposed form of patent non-aggression pact. As of late 2012, the DPL has not been finalised and is not yet seeking members/users.
The project is being worked on by Jason Schultz and Jennifer Urban, two law professors at UC Berkeley. It was first publicly discussed at a conference on May 7th 2010.
Overview
None of the details are finalised, but points being discussed include:[1]
- Member companies would have to commit all their patents. Not just a chosen set, not just the patents of one department/affiliate of the company. (This aspect is still the subject of a lot of discussion)
- Members give all other members an irrevocable licence to freely use their patents.
- Members can leave, but this would not cancel the licences already granted during their membership.
