Trademark Opposition Attorney: How to Fight or Defend a Trademark Application (2026)
A trademark opposition is a formal legal proceeding before the USPTO's Trademark Trial and Appeal Board (TTAB) in which a third party challenges a pending trademark application before it registers. If your trademark rights are threatened by a competitor's pending application — or if your application is being opposed by someone else — you need a trademark opposition attorney. At Michael Meyer Law, TTAB opposition proceedings are handled directly. Contact (402) 321-7532 to discuss an opposition matter.
What Is a Trademark Opposition?
When a trademark application is approved by the USPTO examining attorney, it is published in the Official Gazette — the USPTO's weekly publication — for a 30-day opposition period. During that window, any person who believes they would be damaged by registration of the mark can file a Notice of Opposition with the TTAB to challenge the application before the mark is registered.
A trademark opposition is essentially a trial before the TTAB. The party filing the opposition (the opposer) must prove grounds for opposing the registration. The applicant has the opportunity to defend their application. If the TTAB rules in favor of the opposer, the application is refused and the mark does not register. If the TTAB rules in favor of the applicant, the mark proceeds to registration.
Why oppositions matter: A trademark registration is significantly more difficult to challenge after it issues than before. Filing an opposition during the 30-day publication window — or requesting a 30-day extension of time to oppose — is the most efficient and cost-effective way to prevent a potentially conflicting mark from receiving federal registration. Once a mark registers, challenging it requires a cancellation proceeding, which faces a higher burden in some respects.
Grounds for Trademark Opposition
A trademark opposition must be based on legally recognized grounds. The most common grounds are:
Likelihood of confusion (Section 2(d)): The most frequently asserted ground. The opposer argues that the applied-for mark is so similar to their existing mark, and the goods or services so related, that registration would create a likelihood of consumer confusion. The opposer must demonstrate prior use or prior registration of a mark that would be confused with the applicant's mark.
Descriptiveness (Section 2(e)): The applied-for mark is merely descriptive of the goods or services and has not acquired distinctiveness. A descriptive mark cannot be registered on the Principal Register without proof of secondary meaning — that consumers have come to associate the descriptive term specifically with one source.
Genericness: The applied-for mark is the generic name for the goods or services and can never function as a trademark. Generic marks are not protectable regardless of how long they have been used.
Fraud on the USPTO: The applicant made materially false statements in the application — for example, claiming use in commerce when the mark was not actually in use, or misidentifying the goods and services.
Dilution of a famous mark: The applied-for mark would dilute the distinctiveness or tarnish the reputation of a famous, well-known mark, even without likelihood of confusion. This ground is available only to owners of truly famous marks.
Prior use: The opposer has been using the mark in commerce prior to the applicant's filing date, establishing prior common law rights that would be harmed by the applicant's registration.
Ornamentality / failure to function: The applied-for mark fails to function as a trademark — for example, a decorative phrase on clothing that consumers would not recognize as a brand identifier.
The Trademark Opposition Process
Understanding the TTAB opposition process is essential for anyone involved in an opposition as either the opposer or the applicant.
Publication and the opposition window
After the USPTO examining attorney approves an application, it is published in the Official Gazette. The 30-day opposition period begins on the publication date. Any party who believes they would be damaged by registration may file a Notice of Opposition during this window or request an extension of time to oppose.
Extension of time to oppose
Any party may request a 30-day extension of time to file an opposition without showing cause. Additional extensions totaling up to 120 days from the publication date require a showing of good cause or consent of the applicant. Extensions are commonly used to allow the parties time to negotiate a resolution before committing to an opposition proceeding.
Notice of Opposition
The Notice of Opposition is the pleading that initiates the opposition proceeding. It must identify the opposer, the application being opposed, the grounds for opposition, and the facts supporting each ground. Filing fees are $600 per class of goods or services for electronic filing. Once filed, the TTAB dockets the proceeding and serves the applicant.
Answer
The applicant has 40 days to file an Answer to the Notice of Opposition, admitting or denying the allegations and asserting any affirmative defenses. Failure to answer results in default judgment against the applicant.
Discovery
The parties exchange information and documents relevant to the opposition through the discovery process — interrogatories, document requests, and depositions. The TTAB's discovery period runs approximately 4–6 months, though extensions are commonly granted.
Trial period and evidence
TTAB proceedings are conducted on written submissions rather than live courtroom testimony. Each party submits testimony and evidence during their assigned trial period. Testimony is typically submitted through affidavits or declarations with exhibits.
Briefing
After the trial period closes, both parties submit written briefs arguing why the evidence supports their position. The TTAB may schedule an oral hearing, though oral argument is less common than in district court litigation.
TTAB decision
The TTAB issues a written decision either sustaining the opposition (the application is refused) or dismissing it (the application proceeds to registration). Either party may appeal an adverse TTAB decision to the U.S. Court of Appeals for the Federal Circuit or to a federal district court.
Timeline: A contested trademark opposition typically takes 1–2 years from filing to final decision. Many oppositions settle before reaching a final decision — through coexistence agreements, consent agreements, or the applicant voluntarily abandoning or amending the application.
What a Trademark Opposition Attorney Does
Trademark opposition proceedings involve the same types of legal work as federal court litigation — pleadings, discovery, evidence, and briefing — but before the TTAB rather than a district court. Effective opposition representation requires:
Evaluating the strength of the opposition grounds. Not every pending application that concerns you is worth opposing. Before filing, a trademark opposition attorney analyzes the strength of your claim — how similar are the marks, how related are the goods, how strong is your prior mark — and advises whether an opposition is likely to succeed and whether the cost is justified by the risk the application poses.
Filing or responding to the Notice of Opposition. Drafting a well-pleaded Notice of Opposition that adequately alleges the grounds and supporting facts is critical — a poorly pleaded opposition can be dismissed on procedural grounds before reaching the merits. Similarly, the Answer must address each allegation properly and preserve affirmative defenses.
Managing the discovery process. Discovery in TTAB proceedings requires the same attention to procedure and strategy as federal court discovery. Identifying the right evidence to request, responding to discovery demands, and building the evidentiary record that will support your position at trial all require experienced handling.
Negotiating resolution. Many trademark oppositions resolve through negotiation rather than a final TTAB decision. A coexistence agreement — a formal agreement allowing both parties to use their respective marks under defined conditions — is a common resolution. Consent agreements and amendments to the opposed application's identification of goods and services are also frequent outcomes. An experienced trademark opposition attorney can identify when a negotiated resolution is in your interest and structure the agreement properly.
TTAB trial and briefing. If the proceeding does not settle, building and presenting the evidentiary record through the TTAB's written submission process and crafting the final brief require trademark litigation experience.
Defending Against a Trademark Opposition
If your trademark application has been opposed, the proceeding is adversarial — the opposer is attempting to prevent your mark from registering. You have several options:
Defend the application. If you believe your mark is entitled to registration and the opposition grounds are weak, you can contest the opposition through the full TTAB proceeding. This requires filing an Answer, participating in discovery, submitting evidence during your trial period, and briefing the issues.
Negotiate a resolution. In many cases, the underlying concern of the opposer can be addressed without a full contested proceeding. A consent agreement — in which you agree to certain limitations on your use of the mark (geographic restrictions, specific goods or services, specific channels of trade) — may satisfy the opposer's concerns while allowing your application to proceed. A coexistence agreement can benefit both parties by providing certainty and avoiding the expense of a contested proceeding.
Amend the application. If the opposition is based on the breadth of your identification of goods and services, narrowing the identification to exclude goods or services that directly compete with the opposer's mark may resolve the conflict.
Abandon the application. If the opposition appears likely to succeed and the cost of defending does not justify the risk, voluntarily abandoning the application and refiling with a modified mark may be the most cost-effective path — particularly if you are in the early stages of building your brand.
The critical point for applicants: Do not ignore an opposition. Failure to file an Answer within 40 days results in default judgment — your application is refused and the mark does not register. An opposition proceeding requires active engagement from the moment you receive notice.
Trademark Opposition vs. Trademark Cancellation
Trademark opposition and trademark cancellation are both TTAB proceedings challenging trademark rights, but they target different stages of the registration process.
Trademark opposition challenges a pending trademark application before it registers. The 30-day window after publication is the most efficient time to act — the mark has not yet received federal registration, so the opposer is preventing registration rather than unwinding it.
Trademark cancellation challenges an existing trademark registration after it has already issued. A petition to cancel a registration can be filed at any time after registration (with different grounds available at different timeframes), but the proceeding is more complex in some respects because the registrant has the presumption of a valid registration working in their favor.
If you discover a conflicting mark that is already registered rather than pending, cancellation is the appropriate TTAB proceeding. If the mark is still pending, opposition is available and typically more efficient.
Frequently Asked Questions
What is a trademark opposition attorney?
A trademark opposition attorney is a trademark attorney who handles proceedings before the USPTO's Trademark Trial and Appeal Board (TTAB) to challenge pending trademark applications (opposition) or existing registrations (cancellation). At Michael Meyer Law, trademark opposition proceedings are handled directly by Michael Meyer, USPTO-registered patent and trademark attorney (Reg. No. 78,575).
How long does a trademark opposition take?
A contested trademark opposition typically takes 1–2 years from the Notice of Opposition to a final TTAB decision, including discovery and briefing periods. Many oppositions settle before reaching a final decision. Extensions of time and suspension of proceedings for settlement negotiations are common, and actual timelines vary significantly depending on the complexity of the case and whether the parties reach a negotiated resolution.
What are the grounds for opposing a trademark?
The most common grounds for trademark opposition are likelihood of confusion with a prior mark (Section 2(d)), mere descriptiveness, genericness, fraud on the USPTO, dilution of a famous mark, prior common law use, and failure to function as a trademark. The most frequently litigated ground is likelihood of confusion — that the applied-for mark is so similar to an existing mark, and the goods so related, that registration would create consumer confusion.
How much does a trademark opposition cost?
TTAB filing fees are $600 per class of goods or services. Attorney fees for a trademark opposition vary significantly depending on whether the matter settles early or proceeds through full discovery and briefing. Early-stage negotiations and extensions of time are less expensive than a fully contested proceeding. Michael provides a realistic assessment of likely costs at the outset of any opposition matter.
What happens if I don't respond to a trademark opposition?
If your trademark application has been opposed and you fail to file an Answer within 40 days of the opposition being filed, the TTAB will enter default judgment against you — meaning the opposition is sustained and your application is refused. Your trademark will not register. Ignoring an opposition is never the right response.
Can a trademark opposition be settled?
Yes — the majority of trademark oppositions settle before reaching a final TTAB decision. Common resolutions include coexistence agreements (both parties agree to use their marks under defined conditions), consent agreements, amendment of the opposed application's goods and services identification, and voluntary abandonment of the application. An experienced trademark opposition attorney can identify and negotiate settlements that protect your interests while avoiding the expense of a full contested proceeding.
