Yep, right, nothing can be done -- no patent, nothing, just execution (let the fittest win, I know, it what makes the difference =) ). CLONED, because they used pictures I took, pretend to have the product I sell (it's original art, so I'm pretty sure they don't have another copy) and re-used without changing the tag-line I used. In this context, my question would be: what's the strategy to follow to interact with them?
