An experienced TTAB attorney can also identify early settlement opportunities." } } ], "dateModified": "2026-08-28" } ] --- [](/) - Trademarks - Patents - Copyrights - Data Privacy - Business Legal - [Pricing](/pricing) - Resources - Company Sign inEN · USD Sign in 1.

Anatomy](/assets/bare-anatomy-CBhgu9Ro.webp "Bare Anatomy")![Freedom](/assets/freedom-confectionery-HioHiGYc.webp "Freedom") How it works ## Three steps, whether you file or defend. 1 ### Submit your case details Send us the application or registration number, whether you're filing or defending, and any deadline you've been served. A US-licensed attorney reads the record. Even if GTC didn't file the original application. 2 ### Attorney assesses & quotes Our US-licensed attorney retrieves the mark, reviews the opposing party and the TTAB posture, then sends a strategy recommendation and a transparent quote before any work begins. 3 ### We handle all TTAB filings Once you approve, we prepare and file every TTAB submission. Notice of Opposition or Answer, discovery, and briefs, and keep you informed through settlement, withdrawal, or a TTAB decision. Two sides of one fight ## Whichever side you're on, we handle it. A TTAB opposition has an opposer and an applicant. We represent either, and the same US-licensed attorney team owns the matter end to end, from the first filing to settlement or a decision. ### Filing an opposition Challenge a published application before it registers. - File a Notice of Opposition within 30 days of publication in the Official Gazette - Demonstrate standing and a factual basis for each ground - Filed electronically via ESTTA ($600/class government fee at cost) ### Defending against an opposition Someone opposed your application. Protect what you filed. - File an answer within 40 days of institution, a missed deadline risks default judgment - Raise affirmative defenses, challenge standing, and show distinctiveness or prior use - Negotiate a consent or coexistence agreement where it's the smarter outcome What it costs ## Filing priced upfront, defence quoted after a primary analysis. Filing is standardised, so we quote it from a flat base. Defence depends on the cited grounds, so we scope it after a primary analysis. Either way you see the full quote before any work begins, never billed by surprise. The USPTO ESTTA fee is passed through at cost. ### Filing an opposition Challenge a published mark From $750 - Case assessment and TTAB strategy - Notice of Opposition drafting and filing - USPTO ESTTA fee separate, at cost ($600/class) ### Defending against an opposition Protect your application Quoted per matter - Opposition assessment and defence strategy - Answer drafting and filing, no USPTO government fee - Settlement and coexistence negotiation included These fees cover the initial filing or answer; discovery and trial phases are quoted separately based on complexity. Most TTAB oppositions settle before trial through consent or coexistence agreements, which can significantly reduce overall costs. Post-Registration Attorney Representation is included free for 1 year. [A retainer may apply after that.](/services/us-attorney-representation) Understanding TTAB oppositions ## Grounds, settlement, and what comes next. Everything you need to know about TTAB opposition proceedings. What you can challenge on, how most cases actually resolve, and how opposition differs from cancellation. ### What is a TTAB opposition? A proceeding before the Trademark Trial and Appeal Board challenging a published application. - Filed within 30 days of publication in the Official Gazette - Opposer must demonstrate standing and potential damage - An adversarial proceeding, similar to federal litigation ### Grounds for opposition The legal bases for challenging a mark before the TTAB. - Likelihood of confusion with an existing mark. Section 2(d) - Descriptiveness or genericness. Section 2(e) - Dilution of a famous mark; false suggestion of connection. Section 2(a) - Fraud in the application; geographic misdescriptiveness ### Settlement and resolution Most TTAB oppositions settle before trial, reducing cost and uncertainty. - Consent agreements allowing registration on agreed terms - Coexistence agreements with geographic or product-line boundaries - Amending the application to narrow goods/services and remove the overlap - Voluntary withdrawal of the application ### Opposition vs. cancellation Two TTAB tools that apply at different stages of a mark's life. - Opposition challenges an application before it registers (30-day window + extensions) - Cancellation challenges a mark that has already registered - Some cancellation grounds (e.g. confusion) carry a 5-year window - Both run before the TTAB under similar procedures ### Extensions of time to oppose More time to investigate or negotiate before filing a formal opposition. - The first 30-day extension is automatic and free on request - Further extensions require good cause; the final 60-day step needs consent - Extensions can total up to 120 days from the original publication date - Commonly used while parties negotiate a resolution Get started ## Tell us which side you're on. Both paths start the same way, a US-licensed attorney reads the record and emails you a strategy and a quote before any work begins. [ ### File an opposition Challenge a published application before it registers. Send the serial number and the grounds. We draft and file the Notice of Opposition inside the 30-day window. Start a filing ](/forms/catalog/trademarks-brands/trademark-opposition-filing/US?ref=b2c)[ ### Defend your mark Someone opposed your application. Send the Notice you were served. We read the grounds, scope the defence, and file the Answer inside your 40-day deadline. Start a defence ](/forms/catalog/trademarks-brands/trademark-opposition-defense/US?ref=b2c) Why GTC ## An online-first firm, built for TTAB oppositions. ### Free triage before you commit Send us the application number and a US-licensed attorney reads the grounds, reviews the TTAB posture, and quotes a flat fee, before any work or payment. ### Drafted to the TTAB rules A US-licensed attorney drafts your Notice of Opposition or your Answer to the cited grounds, and you approve every argument before it is filed. ### Your TTAB deadline, diarised We diary the 30-day opposition window, or the 40-day answer date. The moment you engage, and file inside it; a missed answer deadline risks a default judgment. ### One team across 100+ offices The same team handles your TTAB oppositions and your oppositions at every other registry your brand reaches. Your Customer Success Team ## A dedicated team that owns your matter from start to finish. Every GTC client gets a dedicated Account Manager and a Senior Account Manager who learn your business and stay with you from first email to final filing. They are named people who pick up the phone and already know your matter, so every step moves forward without delay. ### Your Account Manager Your day-to-day point of contact, who coordinates every matter, keeps things moving, and already knows your file. They have your full history, so you start every conversation where the last one left off. ### Your Senior Account Manager Senior oversight on strategy and escalations, stepping in as your needs grow, so every important detail stays on track.

An opposition runs on a fixed procedural calendar. Here is what to expect once a mark publishes, and once a Notice is served. 1. Day 0 ### Mark publishes The application appears in the USPTO Official Gazette, opening the 30-day opposition window. We track the date for you. 2. Day 30 ### Opposition deadline A Notice of Opposition must be filed, or a free 30-day extension requested to preserve your right to challenge. Miss it and your only route becomes a costlier cancellation after the mark registers. 3. Up to Day 120 ### Extensions exhausted Further extensions require good cause; the final 60-day step needs the applicant's consent. Extensions can total up to 120 days from publication. 4. Answer due ### Answer filed in your window If you're defending, the Answer is due 40 days after institution. We draft it to the TTAB rules, you approve it, and we file inside the deadline, a missed one risks default judgment. 5. Discovery → decision ### The TTAB decides Discovery, testimony, and briefing run on a fixed calendar; most oppositions settle before trial through consent or coexistence. We see the proceeding through to the TTAB's decision. In their words > I've had the pleasure of working with Rajat for many years. He has expertly guided me through the process of registering my company in the USA, Canada, UK, Australia, New Zealand, and more.

A trademark opposition is a legal proceeding before the Trademark Trial and Appeal Board (TTAB) in which a third party challenges a trademark application that has been published for opposition in the USPTO's Official Gazette. The opposer must demonstrate standing (a real interest in the proceeding) and prove that registration of the mark would damage their rights. It is an adversarial proceeding, similar to federal litigation but conducted entirely on paper before the TTAB. How long do I have to file an opposition? What are the grounds for opposing a trademark? How much does a trademark opposition cost? How long does the opposition process take? What happens if I don't respond to an opposition?
