Someone Opposed Your Trademark: What Happens Now

The application cleared the examiner. It got published. You were weeks away from a registration. Then a notice shows up saying another company has filed an opposition, and your trademark is on hold.

An opposition is one of the most stressful things that can happen to a trademark application, partly because most business owners have never heard of it until it happens to them. It isn't a lawsuit for money, and it doesn't automatically mean you have to rebrand. But it is a formal legal proceeding with real deadlines, and how you handle the first few weeks can decide how it ends. If you've received a notice of opposition, our trademark practice can help you understand where you stand.

What a trademark opposition is

Before the USPTO registers a trademark, it publishes the application so the public can see it. That publication opens a window, generally 30 days, extendable in some cases, for anyone who believes they'd be harmed by the registration to object.

An opposition is that objection. It's filed with the Trademark Trial and Appeal Board (TTAB), an administrative tribunal inside the USPTO. The opposer is asking the Board to refuse your registration.

A few things an opposition is not:

• It's not a lawsuit for damages. The Board decides whether your application should register. It doesn't award money or order you to stop using your name.
• It's not the same as an office action. An office action comes from the examining attorney reviewing your application. An opposition comes from a third party. Our post on what a trademark office action is explains the difference.
• It's not a cease and desist letter, though the two often travel together. If you received both, read our guide on what to do with a trademark cease and desist letter.

Why someone opposes an application

The most common reason is likelihood of confusion. The opposer says your mark is too close to theirs, for goods or services that are too closely related, and customers would mix the two up. Our post on whether two businesses can have the same name explains how that test works.

Other grounds include:

• Priority: the opposer claims it used the name first, even if it never registered.
• Descriptiveness or genericness: the opposer argues your mark just describes the product and shouldn't belong to anyone.
• Dilution: a famous brand argues your mark weakens its distinctiveness, even without direct competition.
• Non-use or false statements: the opposer argues something in your application was inaccurate.

Large companies sometimes oppose aggressively, including against small businesses whose marks are only loosely similar. That doesn't mean they'll win. It does mean the fight can be expensive even when you're right.

The deadline you cannot miss

Once the Board institutes the opposition, it sets a deadline for you to file an answer, generally 40 days from the notice.

If you don't answer on time, the Board can enter a default judgment against you, and your application is refused. That's the single most common way people lose an opposition: not on the merits, but by not responding.

If you receive a notice of opposition, the first step is to find that answer deadline and get counsel involved well before it.

How the process works

An opposition looks a lot like a lawsuit, just in front of an administrative board instead of a court:

1. Answer. You respond to each claim in the notice of opposition.
2. Discovery. Both sides can request documents and information, and take testimony.
3. Trial periods. Each side submits evidence and testimony in writing during set windows.
4. Briefs and decision. The Board reviews the record and decides whether your application registers.

A fully litigated opposition can take a few years. Most don't go that far. Many end in a negotiated settlement, a withdrawal, or a default long before a final decision.

How oppositions usually end

There are a handful of common outcomes:

• Settlement with changes. You narrow the goods or services in your application, modify a logo, or agree to stay out of certain markets. In exchange, the opposer withdraws.
• Coexistence agreement. Both sides agree they can use their marks in their own lanes, and put the terms in writing.
• Withdrawal by the opposer. Sometimes the opposer decides the fight isn't worth it once you respond seriously.
• Abandoning your application. In some cases, rebranding before you've invested more is the smarter business decision.
• A Board decision. If neither side settles, the Board rules.

Which path makes sense depends on how strong the opposer's claim really is, how long and how widely you've used the name, what changes you can live with, and what a full fight would cost compared to a rebrand.

A Michigan-specific note

Michigan businesses sometimes assume a state registration, an LLC filing, or years of local use protects them from an opposition. They don't stop one. The opposition is about the federal application, and the Board looks at the federal record and both sides' use. That said, your history of use in Michigan can be important evidence, especially if you were using the name before the opposer. Keep records of when and where you started using it. Our post on whether an LLC protects your business name covers why an entity filing isn't the same thing as a trademark.

How to lower the odds of an opposition

You can't control who opposes, but you can make it less likely:

• Clear the name before you file. A real clearance search looks for the businesses that are most likely to object, including ones that never registered. We cover why in Trademark Search: Check a Name Before You Brand It.
• Describe your goods and services carefully. An overly broad description can draw objections a narrower one wouldn't.
• Watch the famous brands in your space. A name or logo that leans toward a well-known brand invites a fight, even if you'd likely win it.

Questions we hear often

Do I have to stop using my name during an opposition? An opposition is about registration, not use. But if the opposer also sends a demand letter or files a lawsuit, that's a separate issue to address.

Can I just ignore it? Not without losing. If you don't answer on time, the Board can enter a default judgment and your application is refused.

Does the other side always win if they're a big company? No. The Board decides based on the evidence and the law, not on size. But large opposers can make the process expensive, which is why strategy matters early.

How long does an opposition take? Many end within months through settlement or withdrawal. A fully litigated case can take a few years. Our post on how long trademark registration takes covers the normal timeline without an opposition.
