    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.

    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

    The timeline

    From publication to a TTAB decision.

    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. His deep knowledge of trademark law across jurisdictions is impressive.

    US opposition FAQ

    Frequently asked questions

    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.
