`ttab_proceeding`

Pack: ttab · Endpoint: https://gateway.pipeworx.io/ttab/mcp

Returns one USPTO TTAB proceeding in full: its type (opposition, cancellation, extension of time to oppose, ex parte appeal), status and status date, filing date, interlocutory attorney and paralegal, both parties with their correspondence addresses and every pleaded mark (serial number, registration number, application status), and the complete prosecution history — every docket entry with its date, text, and any due date. Answers “what happened in TTAB proceeding 91308065”, “is this opposition still pending”, “what is the answer deadline”, “which marks were pleaded”. Sourced live from USPTO TTABVUE.
