"The Open Invention Network, the Software Freedom Law Center, and the Linux Foundation have teamed up to create another tool to defend Linux from patents. It will be hosted by the NYU Peer to Patent folks, where Mark Webbink is now. It is called Linux Defenders, and that would be you, in that they are asking folks to provide prior art to block anyone else from patenting it. Over time, this could be very significant as a protective wall. Essentially, as I understand it, it works like this: Since it costs a prohibitive amount of money to file for patents, the workaround is defensive publication. That results in prior art which can then block patents on that prior art. Brilliant, my dear Watson. No kidding."
