In a Rigged Game, Twitter?s IPA Lets Developers Rewrite the Rules

Last month, in response to Yahoo?s wrongheaded patent infringement lawsuit against Facebook, I wrote about my experience filing patents at Yahoo. Patents I helped to file, ostensibly only for defensive purposes, were turned into blunt weapons to thwart innovation and extort money. Yesterday, Twitter announced their Innovator?s Patent Agreement, an open source contract intended to guarantee patents will only be used defensively, even when sold. The IPA seems to directly address the issues raised in my article. Still, the IPA isn?t perfect, and it needs work to protect the intentions of designers and engineers.
