September 24, 2014 — Patent trolls, which has helped to keep the United States in the economic doldrums, are finally being brought to heel by anti-patent groups and court cases. First, the Open Invention Network (OIN), whose members include Google, IBM, NEC, Philips, Red Hat, and Sony, now has more than a thousand licensees in its Linux and open-source, defensive patent pool. In an e-mail , Keith Bergelt, OIN’s CEO said, “The OIN license is becoming part of a broader set of community norms and is increasingly being integrated into the culture of open source/Linux-centric companies. It is for many the foundation around which their IP [intellectual property] strategy is built and a critical enabler of patent non-aggression and freedom to operate.”
