A trademark opposition is one of the most stressful hurdles a brand owner can face during the registration process. If you have received a Notice of Opposition, or if you need to block a competitor’s application, it is critical to understand exactly how this legal mechanism works.
What is a Trademark Opposition?
A trademark opposition is a formal, legal challenge filed by a third party against a pending USPTO trademark application. It occurs when a company or individual believes that their existing trademark rights would be harmed if the new application is allowed to register.
When Does an Opposition Happen?
An opposition does not happen immediately after an application is filed. It can only be filed during a specific window: after the pending trademark application has received preliminary approval from a USPTO examining attorney and is published in the Official Gazette (the USPTO’s official public record).
Once published, the public is given a 30-day window to file an opposition or request an extension of time to oppose.
Proving a “Likelihood of Confusion”
The most common legal basis for filing an opposition is claiming a “likelihood of confusion.” In these proceedings, the party bringing the challenge (the Opposer) must establish two key facts:
-
They have rights to their trademark that predate the rights of the challenged Applicant.
-
The Opposer’s trademark and the Applicant’s trademark are likely to be confused by consumers.
To determine if two marks are legally confusing, the Board generally looks at two primary factors:
-
The Marks: The similarity of the two names in sound, appearance, and overall meaning.
-
The Goods/Services: The similarity and relatedness of the goods or services sold under those trademarks.
The Timeline and Legal Process
A trademark opposition is not a quick administrative review; it is a full trial conducted mostly via paper and online filings before a panel of three judges at the Trademark Trial and Appeal Board (TTAB).
-
The 60-Day Deadline: If you receive a Notice of Opposition, you generally have 60 days to file an Answer. Missing this deadline can result in a default judgment against you, meaning your application will be abandoned.
-
The TBMP: The entire proceeding is strictly governed by the Trademark Trial and Appeal Board Manual of Procedure (TBMP), which dictates the complex rules for legal correspondence, discovery, and evidence.
-
The Duration: While many opposition cases are settled out of court or resolved early, cases that go the distance to final Briefs and a judge’s ruling can take two years or even longer to conclude.
The Bottom Line
Because an opposition is essentially a specialized piece of federal litigation, the stakes—and the procedural rules—are quite high. To best prepare an Answer and plan a strong defense, you should contact an experienced trademark attorney immediately upon receiving a Notice of Opposition.
