anaesthetica writes "The WSJ reports that a San Francisco startup is buying up patents with the promise never to assert them in order to help large corporations hedge against patent trolling firms.

We protect our intellectual property through a combination of copyright, trademark, patent and trade secret laws, employee and third-party nondisclosure agreements, and other methods of protection.
