With its Patent Busting Project, EFF is targeting patents that it claims are invalid and hurt ordinary people by threatening innovation. In this case, the patent affects a technology that has made voice calls more affordable and that depends partly on independent inventors for new advances, said EFF Legal Director Cindy Cohn.
"VoIP is one of these kinds of technologies that really frees people," Cohn said. EFF is worried that fear of lawsuits by C2 could inhibit developers from making new VoIP products available. Meanwhile, its patent is one that never should have been granted, Cohn said.
