TTAB Opposition Search — Reading the 647K-Proceeding Docket.

What the TTAB does (and does not).

The TTAB has jurisdiction over two kinds of disputes: oppositions to pending applications, and cancellations of existing registrations. The opposition window opens when an application is published for opposition in the Official Gazette and runs 30 days, extendable by request. After registration, the same grounds become cancellation grounds, with a five-year statute of limitations on most of them and no limit on a small set including fraud and genericness.

The board does not enforce trademark rights in the marketplace — that happens in U.S. district court. The board adjudicates registrability: whether the applicant has the right to register the mark on the federal register. The remedies are limited to refusal of registration, cancellation of registration, or partial restriction of goods-and-services. The board does not award damages or injunctions.

This matters for clearance because the TTAB is the cheapest litigation forum for a senior-mark holder. An opposition filing fee is $600 per class per opposer. The proceeding can be settled in weeks or dragged out for years. For senior-mark holders who oppose programmatically — and there are many — the TTAB is the first line of defense against junior junior marks that look like dilution risks.

Walking through TTABVUE.

TTABVUE is the public docket. The interface is functional but austere — search by proceeding number, by party name, by mark, or by date. For clearance search, four queries cover most situations.

1. Search by senior-mark owner. Enter the owner of the senior mark you flagged in USPTO TESS into the Party Name field. The result list returns every proceeding this party has been involved in as opposer, applicant, petitioner, or registrant. If the count is high and most are oppositions filed by this party, you have a litigious holder.
2. Search by senior mark. Enter the mark text into the Mark field. This surfaces every proceeding referencing that mark — including the proceedings where the mark was opposed but survived. Reading the survivor briefs is a free education in how to argue around a §2(d) refusal.
3. Search by proceeding number. If you have a specific TTAB proceeding number from a TESS hit’s prosecution history, pull the full docket. The docket lists every filing — complaint, answer, motions, briefs, exhibits, the board’s final decision.
4. Browse by date. Useful only for trend analysis — the daily opposition feed reveals which classes are seeing the most activity. Class 9, 25, 30, 33, and 42 typically dominate.

The signal you’re looking for is a pattern: an owner who has filed three or more oppositions in your Nice class, who has won two of them on §2(d) grounds, is telegraphing that they will oppose any junior mark in their class that crosses a phonetic-distance threshold. Their litigation pattern is a free signal. Most founders never read it.

Anatomy of a TTAB decision.

A typical TTAB final decision is 20–60 pages of careful reasoning. The structure is consistent enough that you can skim three of them and learn the form. Five sections, in order:

• Procedural history. Who filed what, when, against whom. The proceeding number, the marks at issue, the goods-and-services descriptions.
• Evidence. The exhibits each party submitted. For a §2(d) proceeding, this is where the opposer’s use evidence, the applicant’s use evidence, the third-party use evidence, and any consumer-survey evidence lives.
• Likelihood-of-confusion analysis. The DuPont-factor walk-through. The board addresses each relevant factor in turn, citing the evidence record. This is where you learn how the board weighs sight, sound, meaning, channels of trade, and the other ten factors in your fact pattern.
• Disposition. The board sustains the opposition (refusing registration), dismisses the opposition (allowing registration), or grants the cancellation (cancelling the registration). For oppositions of multi-class applications, the disposition can be partial — sustained as to some classes, dismissed as to others.
• Concurring or dissenting opinions. Rare but illuminating. Concurring opinions often hint at how the board would have ruled on a slightly different fact pattern. Worth reading when present.

If you read three opposition decisions in your Nice class — one where the opposition was sustained, one where it was dismissed, one with a concurring opinion — you will have learned more about how examiners and the board weigh DuPont factor (1) than any blog post can teach you. The decisions are free and they are the law. We unpack the factors in the cluster page on §2(d) Likelihood of Confusion.

The base rates that matter.

Most applicants never face a TTAB proceeding. Of the 736,778 applications filed with the USPTO in FY2024, only a small fraction (~3–5% by typical year) progress to an opposition filing, and many of those settle before the board issues a final decision. The base rate of opposition is low.

The conditional rate — given that your candidate is phonetically close to a senior mark in your Nice class with a litigious owner — is dramatically higher. We have seen owners who oppose more than 80% of new applications in their class that breach a phonetic-distance threshold. The base rate is low; the conditional rate, given the wrong neighbor, is high.

This is why the TTABVUE check is non-negotiable on a finalist candidate. The cost of pulling the senior-mark owner’s docket is fifteen minutes. The cost of ignoring that signal and getting opposed is roughly $30,000–$100,000 in legal fees to defend, settle, or amend. The expected-value math is overwhelming.

The extension-of-time signal.

Most opposition activity that founders never see is the extension-of-time-to-oppose request. The opposition window is 30 days from Official Gazette publication, extendable on request. The TTAB grants 30-day, 60-day, and 90-day extensions liberally, and the requests are public.

An extension request is a soft signal: a senior-mark holder has noticed your application, has reserved the option to oppose, and is either evaluating the risk or negotiating with you privately. About half of extension requests do not ripen into oppositions — the parties either settle, the senior-mark holder decides not to file, or the applicant amends to avoid the conflict. The other half do.

If you check TTABVUE for your senior-mark candidates and find that the owner routinely files 90-day extensions against junior applications in your class, that is a strong tell. The owner is risk-averse and inclined to oppose. Behave accordingly — amend your goods-and-services, narrow your Nice class, or pick a different candidate.

Where TTAB fits in the clearance ladder.

The TTAB lookup is the second of three registry sweeps that compose a thorough clearance check. The sequence:

1. USPTO TESS surfaces the senior marks themselves — word marks, design marks, pending applications, registered marks.
2. TTABVUE surfaces the litigation pattern around each senior mark — who’s been opposed, who opposed them, what’s the disposition rate.
3. Madrid Protocol Monitor surfaces international registrations that designate the US — these are in TESS too, but reading Madrid Monitor directly catches what TESS doesn’t.

How Etymolt verifies trademarks.

Etymolt indexes the full TTABVUE corpus — 647K proceedings as of 2026-05. When a candidate runs through POST /v1/verify, the trademark axis surfaces every senior-mark hit and every TTAB proceeding involving the senior-mark holder, with disposition statistics aggregated by class. A senior mark whose owner has opposed three junior applications in your class with a sustained-rate above 60% will be flagged as a high-risk neighbor. Every flag traces to a TTAB proceeding number. The verdict is attested and permalinked. Full methodology at /methodology. If you’re new to the four-level clearance ladder, start with How to Check If a Brand Name Is Trademarked.
