Reference: EFF and Coalition of Organizations Launch Patent Troll Information Clearinghouse

From the Electronic Frontier Foundation Deeplinks Blog:

The Electronic Frontier Foundation (EFF) and a coalition of organizations and law schools today launched the newest tool in the fight against patent trolls: Trolling Effects. 

[Our emphasis] The online resource aims to unite and empower would-be victims of patent trolls through a crowdsourced database of demand letters and to serve as a clearinghouse of information on the troll epidemic.


“Trolling Effects began with the idea that people need to come together to defeat patent trolls,” said EFF Staff Attorney Julie Samuels, who also holds the Mark Cuban Chair to Eliminate Stupid Patents. “Innovators who previously would have had to face the troll threat alone can use this new collaborative tool to share information and intelligence.”

Other members of the Trolling Effects coalition include: Application Developers Alliance, Ask Patents, Engelberg Center on Innovation Law & Policy at NYU School of Law, Engine Advocacy, Public Knowledge, PUBPAT, and the Samuelson Law, Technology & Public Policy Clinic at Berkeley Law.
