Any chance you could post (or privately send to me) information about the process by which you contractually set up patents so they can only be used defensively? I'm very much interested in doing the same.

BTW, you're taking a lot of heat in this thread that you don't deserve. I work at a VC funded startup (with USV as an investor no less) and I basically agree with you.

Don't worry about the heat. Karma here has no value, or perhaps even negative value, to me. What I'm saying about VCs, startups, and patents is real and important, even if some self-interested HN'ers don't want it heard or even if Fred was the wrong frame on which to hang that picture. I'll burn some karma to get the word out about the real source of the problem and the real solution.

To answer your question, of course IANAL but the way to do this is to assign the patents to an external entity such as http://www.patentcommons.org/ or http://www.openinventionnetwork.com/, where that entity has a charter allowing only defensive use - and preferably with other entities involved to enforce that charter. A public statement like http://www.redhat.com/legal/patent_policy.html doesn't hurt either, though it's not legally binding. Now, PC or OIN might not be the exact right vehicle for you, for other reasons, but that's the basic approach.

Disclaimer: I work for Red Hat, which is a strong proponent of this approach and supporter of these organizations. Until software patents go away - and Red Hat is supporting that effort too - this is the only way to play the game that is both safe and (IMO) moral.
