Velcroman1 writes: Yahoo is suing Facebook for patent infringement — and the people responsible for Yahoo’s patents are outraged. Andy Baio sold Upcoming.org to Yahoo in 2005 for an undisclosed sum, and agreed at the time to help the company file for patents based on the site he had invented and the code he had written. Baio was hesitant to do so, but told Wired.com that he thought he was helping as a precautionary measure. “I thought I was giving them a shield,” Baio said. “It turns out I gave them a missile with my name permanently engraved on it.” He helped Yahoo file for eight patents, four of which were later granted. And while none were cited in the Yahoo complaint, Baio said a handful were now “weaponized to use against people like me.” And he isn't alone.
