Yeah, that is my next step. I have the name trademarked, and I don't see how someone could trademark an anchor. It would have to be identical in every respect.
IANAL - but it seems like the standard used for these things is if the image is close enough to confuse the average (i.e. not so bright) person then it is an infringement.
My first thought when I looked at the logo was "Anchor Steam may have an issue with that" and I don't live in a place where their beers are even sold. That doesn't really mean anything though, I'm a worrier by nature. "Every silver lining has a tough of gray" seemed like a so obviously true statement that there was no need to write it down.
