capedgirardeau writes "Via Cory Doctorow at BoingBoing:: 'Ars Technica's Jon Brodkin has an in-depth look at the "Defensive Patent License," a kind of judo for the patent system created by ... EFF's Jason Schultz (who started EFF's Patent Busting Project) and ... Jen Urban (who co-created the ChillingEffects clearinghouse). As you'd expect from two such killer legal freedom fighters, the DPL is audacious, exciting, and wicked cool. It's a license pool that companies opt into, and members of the pool pledge not to sue one another for infringement. If you're ever being sued for patent infringement, you can get an automatic license to a conflicting patent just by throwing your patents into the pool. The more patent trolls threaten people, the more incentive there is to join the league of Internet patent freedom fighters."
