Maybe I'm missing something....
But wouldn't it just make simple common sense that any company participating in a standards body or similar group that essentially requires disclosure of any held patents. That and signing a waiver for use of any relevant patents that may be involved.
Patent laws suck enough, and I still smile everytime I reread any SCO article. But then again when you live in a society that believes in instant satisfaction, something for nothing, and nothing is ever your fault, what do you expect.
