Keith Bergelt, CEO of the Open Invention Network (OIN), described the circumstances which led the company to recently purchase 22 Microsoft patents, as part of a talk at the first LinuxCon. While the circumstances surrounding that purchase were quite interesting—and indicative of Microsoft's patent strategy—he also described the mission of OIN as a protector of Linux from patent trolls. Because patents are likely to be a threat to Linux for a long time to come, organizations like OIN are needed to allow Linux development to continue with as few patent impediments as possible.
