Search our trademark database

Trademark search system  

With the retirement of the legacy Trademark Electronic Search System (TESS) on November 30, 2023, we have transitioned the system to search for pending and live trademark applications and registrations. The cloud-based trademark search system provides a modern, more stable search experience. You'll find a simplified interface and new capabilities to meet your needs.

Watch the recorded webinars below to learn how to use the system. They're intended for both new users and experienced practitioners. Each webinar builds upon the prior event and covers more complex subject matter. You’re welcome to attend all three, or you can choose which ones are right for you depending on your skill level. To view them in full-screen, click play, then click on the YouTube logo in the bottom right corner of the video. 

You can also register for an upcoming Federal trademark searching: Overview webinar. These webinars repeat every two weeks and provide a brief demonstration of how the system works, along with a discussion of the likelihood of confusion analysis used when conducting a search.
