What do I do if someone is using my trade mark?

Well, the first thing that I would say is take some advice from your trade mark attorney as to your options there. And then you may be able to sue them for trade mark infringement if they're using your trade mark in relation to the same goods that you have registered your trade mark, or even if those are similar goods.
