Expert Research Teams

Our research teams are custom-assembled, based on the technology of the requested research. Each team in led by a project manager, who is a patent attorney* with the requisite subject matter expertise. The project manager acts as a valuable liaison before, during, and after each search project allowing you to get the results you need.

Our veteran search professionals include patent attorneys*, patent agents, and former patent examiners, all with extensive technical knowledge. They utilize sophisticated search strategies for each project, accounting for individual features and combinations using multiple classifications, subclasses, keywords, and synonyms.

U.S. Trademark Searches

Comprehensive Trademark Search

Cardinal’s most commonly ordered search is our U.S. Comprehensive Trademark Search. The Comprehensive search provides the best overall analysis as to what is present in the stream of commerce. This search includes all relevant marks which are registered with the USPTO, as well as pending, cancelled, and abandoned marks. Our trademark attorneys also search state trademark registers, related common law databases including marketing and news sources, corporate name directories, and top-level domain registers to give a full comprehensive report.

Knock-Out Trademark Search

Our Design Trademark Search looks for trademark design availability within the U.S. Our experienced trademark analysts break down the design elements of the subject mark and utilize the same to uncover pending and abandoned U.S. trademark applications and registered and cancelled U.S. trademarks.
