Today, everyone — yes, even Microsoft — use Linux and open-source. It’s been years since Linux was under attack by SCO for imaginary copyright violations, and then Microsoft CEO Steve Ballmer claimed that Linux violated over 200 of Microsoft’s patents. So over 15-years ago, the Open Invention Network (OIN) patent consortium was formed to defend Linux against intellectual property (IP) attacks. Even so, Linux and open-source software are still under attack from patent trolls and other attackers. That’s where the Open Invention Network (OIN) steps up by expanding its patent non-aggression coverage by updating its Linux System definition.
