TTAB Opposition Tracker

Track TTAB trademark opposition and cancellation proceedings. Built for IP counsel, brand teams, researchers and AI agents.

This actor surfaces public IP records as data for your attorney or IP team — it is not legal advice or a legal clearance opinion.

⏰ Run this as a opposition watch (recommended)

Every IP registry actor is a monitoring subscription, not a one-shot lookup. Schedule a weekly sweep and catch new filings as they land:

{
  "query": "your mark",
  "limit": 100
}

Weekly cron (0 8 * * 1) turns this into an always-on opposition watch.
