In essence, this makes the company’s library over 60,000 patents open source and available to OIN members, via ZDNet. > OIN provides a license platform for Linux for around 2,400 companies — from individual developers to huge companies like Google and IBM — and all members get access to both OIN-owned patents and cross-licenses between other OIN licensees, royalty-free.
