Tangent TESS Helper

This extension overlays the United States Patent and Trademark Office website. It simplifies the process of checking whether a word or phrase is a live trademark in categories that are important to ‘print on demand’ creators. The user enters the word or phrase they would like to check and the extension autofills the appropriate fields on USPTO’s TESS Search System so you can quickly and easily search for live trademarks in the class categories 025 (Clothing), 009 (Electronics) and 016 (Books).
