November 19, 2019 – Open-source software — heck, all software — has been plagued by patent trolls for decades. The Open Invention Network (OIN), the largest patent non-aggression community in history, is now expanding protection of open-source and Linux by partnering with IBM, the Linux Foundation, and Microsoft to further protect it from Patent Assertion Entities (PAEs), aka patent trolls. This new consortium is doing this by supporting Unified Patents’ Open Source Zone with a substantial annual subscription.
