Even though your registration has lapsed because you did not file proof of use, you probably still have very substantial trademark rights. Likewise, it appears that the other company is using photographs of your product to sell their product. This is also a violation of the Lanham Act, and is a relatively easy claim to make. You probably also have a copyright claim for use of your pictures.All in all, it looks like these people have put themselves in quite a vulnerable position. However, keep in mind that you need to act promptly otherwise a court may discount your claim.
