How Do You Oppose a Trademark Application at the TTAB?
You have 30 days from publication in the Official Gazette to oppose a trademark application, or to buy time with an extension. Here is how the process runs.
The clock starts the day the USPTO publishes an application in the Official Gazette. From that date you have 30 days to oppose a trademark application or to ask for more time, and if you do neither the mark moves on toward registration. The USPTO does not call you. The only way to know a conflicting mark has been published is to watch for it, which is why most brand owners who use our TTAB opposition and trademark enforcement practice start with a watch service rather than a filing.
An opposition is a proceeding before the Trademark Trial and Appeal Board (TTAB). It is decided on a written record by administrative trademark judges, and the only question is whether the application should register. The Board cannot stop anyone from using a mark or award money. Keep that limit in mind from the first day, because it shapes what an opposition can achieve.
When you can oppose a trademark application
The 30-day window runs from the publication date printed in the Official Gazette. Within that window you can file a notice of opposition or a request for an extension of time. The first extension is routinely granted, and later ones can push the total period to 180 days from publication, though those require good cause or the applicant’s written consent. Extensions are useful when you want to send a demand letter and negotiate before committing to a filing, but every extension request has its own deadline, and missing one ends your right to oppose.
If the application has not yet published, a letter of protest is a cheaper option. You submit evidence bearing on registrability, such as your prior registration, and the USPTO decides whether to forward it to the examining attorney. You take no further part. A letter of protest filed before publication can lead to a refusal that makes an opposition unnecessary, so check the application’s status before you decide which tool to use. Our trademark search and clearance work often turns up pending applications at exactly this stage.
Who has standing and on what grounds
You need a real interest in the outcome and a reasonable belief that registration would damage you. Owning a prior registration or a prior use of a similar mark for related goods is the usual basis. A competitor with no mark of its own can still have standing on some grounds, such as descriptiveness, if it has a commercial need to use the term.
The grounds come from the Lanham Act. The most common are:
- Likelihood of confusion with a mark you used or registered first.
- Mere descriptiveness, or genericness, of the applied-for term.
- Dilution of a famous mark by blurring or tarnishment.
- No bona fide intent to use the mark when the application was filed.
- Fraud on the USPTO in the application.
Priority decides most confusion cases. If the applicant used its mark before you used yours, your opposition will likely fail even if the marks are nearly identical. Pull your earliest dated proof of use before you plead anything.
What happens after you file the notice of opposition
The notice is filed through the Board’s ESTTA system and must state each ground with enough facts to support it. The Board then issues an institution order with the full schedule. The applicant has a set period to answer and may bring a counterclaim to cancel your own registration, which is one reason to assess your registration’s vulnerabilities before you file.
The schedule runs in stages:
- A discovery conference between the parties, followed by initial disclosures.
- Discovery: interrogatories, document requests, requests for admission and depositions, on the Board’s timeline.
- Expert disclosures and pretrial disclosures.
- Testimony periods, where each side submits evidence by declaration or deposition and documents through notices of reliance.
- Briefs, an optional oral hearing, and a written decision.
There is no live trial. The judges read the record and the briefs. Evidence you fail to introduce during your testimony period is not considered, which trips up parties who treat the opposition like a demand letter with a docket number. A losing party can appeal to the Federal Circuit on the record or file a civil action in district court, where new evidence is allowed.
Settlement and faster alternatives
Most oppositions end in settlement. A coexistence agreement, an amendment narrowing the applicant’s goods, or a withdrawal with consent resolves the conflict without a decision. The Board will suspend the proceeding while you negotiate. Think carefully before signing a coexistence deal, because a term that seemed harmless at the time can block your own expansion into new goods or territories years later.
If both sides want a decision but not a full trial, Accelerated Case Resolution lets you stipulate to a shorter schedule and a summary judgment style record. It fits cases where the facts are not seriously disputed and the question is a legal one, such as whether two marks are confusingly similar.
Common mistakes that sink an opposition
Filing without checking priority is the first. Pleading every ground available instead of the two you can prove is the second, because weak claims cost discovery time and credibility. Letting your own registration lapse mid-proceeding is a quiet third; a counterclaim or a missed Section 8 filing can leave you with no mark to assert. And sending an aggressive demand letter before you have confirmed your position can prompt the applicant to sue first in a forum of its choosing, a risk we discuss in our post on trademark cease and desist letters.
Finally, remember that winning an opposition keeps a mark off the register. It does not take the mark out of the marketplace. If the applicant keeps using it, you will need a federal court claim, and if the mark has already registered by the time you act, you are looking at a trademark cancellation proceeding instead.
If a conflicting mark has just published, or you have received a notice of opposition against your own application, Capitol Law Partners can review the publication date, your priority evidence and the strongest grounds before the deadline passes. Schedule a consultation.
