Trademark infringement
http://en.wikipedia.org/wiki/Trademark_infringement
Trademark infringement is a violation of the exclusive rights attaching to a trademark without the authorization of the trademark owner or any licensees (provided that such authorization was within the scope of the license). Infringement may occur when one party, the "infringer", uses a trademark which is identical or confusingly similar to a trademark owned by another party, in relation to products or services which are identical or similar to the products or services which the registration covers. An owner of a trademark may commence legal proceedings against a party which infringes its registration.
