USPTO Trademark Gazette Change Watch

Receive seed-zero weekly records when matching marks or owners appear in the public USPTO Trademark Official Gazette (TMOG) as publications-for-opposition, registrations, renewals, cancellations or corrections.

Configure serial/registration numbers, mark or owner terms, Nice classes and event types. The first complete run seeds a private baseline without alerts; later Tuesday issues produce only new matching Gazette events as deltas, each with an official PDF/page receipt. USPTO describes the TMOG as its Tuesday publication containing trademark bibliographic information plus lists of cancelled and renewed registrations.

What you get

• trademark_delta — a confirmed new Gazette event on a watched mark (the signal). delta_type is the event type or CORRECTED_ENTRY; carries before/after, changed_fields, and an office-scoped composite_id (USPTO:SN… / USPTO:RN…).
• gazette_record — a snapshot-mode record (when watchMode=false).
• source_receipt — always emitted, never billed: terminal state, canary result, issues processed, pages parsed, byte/request counters, backlog.

Use cases

Trademark counsel watch publication/registration records (30-day opposition window); brand teams monitor terms/classes; IP data teams ingest dated Gazette records; agencies route matching filings for review.

Honest limits

Not TSDR live status, legal docketing, comprehensive clearance, ownership verification or legal advice. The Gazette is weekly and event-oriented — absence proves nothing. Design-only marks may have null mark text. Public issue PDFs are large (hundreds of MB) and catch-up is capped at 3 issues/run. TSDR/ODP APIs are excluded because they now require an account/API key. Blocks, malformed issues and objections fail loud (BLOCKED), never a clean empty.

Compliance

Public / logged-out official USPTO PDFs only. No login, API key, CAPTCHA or paywall defeating; no licensed source or third-party mirror; robots honored; complies on objection. Identity is office + serial/registration number; official status codes only — legal outcomes are never inferred.
