TTAB Proceedings Data — Oppositions, Cancellations & More
We've added a brand new data source: Trademark Trial and Appeal Board (TTAB) proceedings. You can now see oppositions, cancellations, extensions of time, expungement petitions, and reexamination proceedings. Each proceeding includes the full prosecution history, party details (petitioner and defendant), and the trademarks involved. This is invaluable for monitoring brands under dispute and understanding the competitive landscape.
