I'm surprised you guys are bothered by this. The registrant isn't going to be able to enforce the trademark, so why not save your energy and ignore him?
You really don't think that if one were established as the trademark holder on Bitcoin they couldn't cause greif for a domesticly run business that was buying, selling or trading Bitcoin? I'd like to think in the long run the business would win out but at what cost? That is what bothers me about it..
