Trademark Opposition: How to Challenge or Defend a Mark at the TTAB

Here is the short version. You have 30 days from publication to oppose, and you must file electronically. The owner of the application then has 60 days from service to answer. The Trademark Trial and Appeal Board (TTAB) decides only the right to register, not damages. If you lose, you can appeal to the Federal Circuit or file a civil action.

What is the TTAB, and what does it decide?

The TTAB is an administrative tribunal inside the USPTO that decides oppositions, cancellations, and related disputes about registrability. It does not award money or issue injunctions. Its only job is to decide whether a trademark can register.

Who can oppose a trademark application?

Any person who believes they would be damaged by registration may oppose once the application is published. That entitlement comes from Lanham Act Section 13, 15 U.S.C. § 1063.

When does the 30-day clock start, and can you extend it?

The 30-day window starts when the application is published in the USPTO's Official Gazette (publication is required by 15 U.S.C. § 1062). You can request an extension of time to oppose if you act before the window closes; longer extensions need a stated reason or the consent of the owner of the application. The TTAB rules are in 37 C.F.R. Part 2. Always confirm current timing on the USPTO site before filing.

What does it cost to oppose?

The USPTO fee for a notice of opposition is $600 per class opposed. Extensions of time carry their own fees. Professional fees are the larger cost, and they scale with how far the case goes: a case that settles in the first months costs a fraction of one that reaches trial. A case that goes all the way to a final decision usually takes more than a year; most never get that far.

How do you file a notice of opposition, and what must it include?

File electronically through TTAB Center, the Board's online filing system for new cases and motions.

Your pleading needs a short and plain statement showing your entitlement to relief and the legal grounds for opposition. In practice:

• Identify the opposed application by serial number and trademark.
• Say why you are entitled to bring the case, for example ownership of a prior trademark or another legally protectable interest.
• State the statutory grounds, such as likelihood of confusion or descriptiveness, with enough facts to make the claim plausible.
• Ask for the relief the Board can give: refusal of registration.

Once filed, the Board issues an institution order that sets all deadlines.

What if your application is opposed? The answer and default risk

If you receive a notice of opposition, you generally have 60 days from service to file an answer under 37 C.F.R. § 2.106. Missing the deadline can lead to default judgment against the application.

An answer should admit or deny each numbered allegation and assert any defenses recognized by Board practice. If you need time to explore settlement or hire counsel, act early and use proper motions rather than letting deadlines pass.

From our side of the table, two failure modes show up again and again: a late answer that triggers a default motion, and a bare-bones opposition that never pleads entitlement to relief. Both are avoidable with disciplined calendaring and one focused revision before filing.

What happens after the pleadings? Disclosures, discovery, and trial

TTAB oppositions follow a federal-litigation-style schedule adapted by the Board's rules (37 C.F.R. Part 2, Subpart D) and explained in the TTAB Manual of Procedure (TBMP). At a high level:

• The institution order sets dates for the required conference, initial disclosures, and discovery.
• Discovery covers documents, interrogatories, and depositions under the Board's modified rules.
• Trial is by written record with testimony periods. Evidence comes in by deposition or by notice of reliance.
• Final briefs follow, with optional oral argument if a party asks.

What are common legal grounds for opposition?

Most oppositions rely on one or more statutory refusals in 15 U.S.C. § 1052:

• Likelihood of confusion with an earlier trademark under Section 2(d).
• Mere descriptiveness or genericness under Section 2(e).
• Other absolute grounds in Section 2, such as deceptive matter or false suggestion of a connection.

Depending on the facts, dilution or false association claims under 15 U.S.C. § 1125 may also be pleaded.

If confusion is at issue, make sure your evidence plan fits the factors the Board considers. Start with a full search and marketplace facts; a free trademark check is a quick first pass, and our team pairs a register search with marketplace snapshots that show how consumers encounter the goods.

How do you monitor the case record and filings?

Use TTABVUE, the Board's public docket. You can search by trademark, party name, or opposition number and download most filings and Board orders. For filing new papers, use TTAB Center.

Practical Ways to Keep Cost and Risk in Check

• Ask for an extension of time to oppose while you assess the record. This preserves your rights while you negotiate or build facts.
• Consider a consent agreement or a tailored amendment of goods or services (see the next section). Either can resolve a case quickly if the commercial reality supports it.
• Narrow your claims. One strong ground is better than five weak ones.
• Calendar the answer, disclosure, and trial periods on day one. The Board enforces these dates.
• If you get opposed often, or want to catch conflicting filings before they register, run a watch on the Official Gazette. Our trademark monitoring service does this, and our monitoring and enforcement guide shows how to set it up.

Settling With a Consent or Coexistence Agreement

Most oppositions end in a deal, not a decision. A coexistence (or consent) agreement is a contract in which the parties carve up the market, by goods and services, channels, territory, or trade dress, so that both trademarks can coexist without confusion. The TTAB and USPTO examiners give weight to these agreements, but only when they explain why confusion will not happen. Signatures alone do not persuade.

What makes a consent agreement persuasive:

• Specific limits: which goods and services each side will and will not use the trademark for, mirrored in an amendment to the application.
• Marketplace facts: different channels, price points, customers, or packaging that keep the trademarks apart.
• Concrete safeguards: labeling commitments, notice-and-negotiate steps before either side expands into new goods, classes, or channels.
• Quality control where the parties' goods are close, so parallel use does not erode either trademark.

Drafting checklist:

• Parties, trademark definitions, and every application and registration covered.
• Goods and services matrix with clear carve-ins and carve-outs by class.
• Territory and channel splits (retail, e-commerce, marketplaces, B2B).
• Marketing limits (keywords, hashtags, domain names, handle formats).
• Get-up and packaging standards, color and shape limits.
• Expansion protocol for new sub-brands, classes, or regions.
• Term, termination, wind-down, and sell-off provisions.
• Governing law and dispute resolution.

There is no USPTO fee to submit a consent agreement in examination or to the Board. Once signed, the opposer withdraws the opposition and the owner of the application files any agreed amendment.

Appeals and What the TTAB Cannot Do

The TTAB decides registrability. It does not award damages or injunctions. If you need marketplace remedies, for example to stop an infringer from selling, that happens in court, often starting with a cease-and-desist letter. After a final decision, a party may appeal to the U.S. Court of Appeals for the Federal Circuit or file a civil action in a United States district court under 15 U.S.C. §§ 1070 to 1071.

Filing or Defending With Counsel

TTAB oppositions move quickly and turn on the record you build. At GTC, our experienced attorneys prepare your pleadings, manage discovery, and argue your case. We also settle cases early when that serves your goals. If you are weighing an opposition or have been served with one, we can step in on short notice through our trademark opposition service. Terms you meet along the way (institution order, notice of reliance, consent agreement) are defined in our glossary.
