What is a Notice of Opposition for Trademarks and How Does it Work?

A notice of opposition is a legal document that needs to be filed with a trademark office to stop a trademark application from being registered. This is usually as a result of likelihood of confusion with existing marks.

If you want to file a notice of opposition to stop someone’s trademark from being registered, you’ll have to follow some important steps.

Read the rest of this article to explore the following key aspects of a notice of opposition:

  • The grounds for a valid notice of opposition.
  • The steps to file a notice of opposition.
  • What happens after filing.
  • How to strengthen your claim.
  • How a lawyer can help you with a notice of opposition.
  • Where to find a reputable lawyer.

What Grounds are Required for a Notice of Opposition?

Opposing a trademark isn’t just about stating that a trademark should not be registered. You have to have valid grounds for opposing a trademark, backed by evidence. These grounds include the following:

  • Similarity. This is a common reason why someone might file an opposition. It means that the trademark being applied for is too similar to a registered trademark, which is likely to cause confusion in the market.
  • Lack of distinctiveness. If a trademark isn’t distinct enough, such as if it’s generic, it can be opposed.

If you want to oppose the filing of a trademark, you should provide evidence to support your claim, such as proof that your trademark is similar to the other party’s.

How Do You File a Notice of Opposition?

To file a notice of opposition, you’ll have to access the Trademark Trial and Appeal Board (TTAB) Center on the United States Patent and Trademark Office (USPTO) website.

Here are the steps to follow.

Open a New Submission

You must set up a MyUspto.gov account to access the TTAB Center. Once you’re in, choose the “New submission” option. You’ll have to provide details about the trademark application you want to oppose, such as a serial number or registration number.

  • If the trademark is registered, you should include a registration or application number. This also applies if you have a common-law mark that’s depicted in a trademark application.
  • If you own a common-law mark that isn’t depicted in an application, you’ll include an image of the mark, in JPEG format.
  • If your common-law mark is made up of words without any designs, you can type it into the form.

Include a Proper Pleading

A proper pleading is a short statement of the claim you are making. It should include facts that establish you have a legal standing to oppose the trademark registration. It’s important to note that you don’t have to prove your claims at this stage. It’s enough to state them in good faith.

Submit it at the Right Time

You must file your notice of opposition within 30 days after publication of the application being opposed.

Pay a Fee

When submitting your notice of opposition, you’ll have to pay a fee. As of this time of writing, electronic submissions cost $600.

Select a Reason for the Opposition

You have to have a valid claim, with some popular reasons being:

  • Likelihood of confusion with an existing trademark.
  • Generic nature of the mark.
  • No intent to use the trademark in commerce.
  • Fraud during the trademark application process.

What Happens After Filing the Notice of Opposition?

After you submit a notice of opposition, the trademark applicant can file their response to it within 60 days. The submission will then move through various phases, which include:

  • Discovery period. Both parties take depositions and request documents from each other.
  • Trial period. Parties send testimonies and evidence to support their claims.
  • Briefing. Parties send written briefs, and then a hearing might be requested.
  • Final decision. The TTAB judges will consider both parties’ cases and evidence, before making a final decision.

How Do You Strengthen Your Opposition When Dealing with the TTAB?

There are various ways to strengthen your case when submitting a notice of opposition, such as by:

  • Having at-hand copies of your applications and registrations, such as if you want to argue that another trademark is too similar to your registered mark.
  • Showing evidence of use in commerce. This can include showing evidence of product labels and packaging.
  • Explaining and proving the likelihood of confusion. This is when you show evidence that the trademark can cause confusion, such as if your customers have been misdirected to the other party’s website because of their trademark.

How Can a Lawyer Help You with a Notice of Opposition?

A lawyer is valuable to offer legal guidance through the process of filing a notice of opposition. Here is how they can help you:

  • They’ll review the notice of opposition to check that it has a strong legal standing.
  • They’ll ensure you meet all deadlines and filing requirements.
  • They’ll gather supporting documents you require for the TTAB, knowing what will work best to strengthen your position.
  • They’ll check for any weakness in your claims so that you don’t make mistakes that can prevent the registration from being stopped.
  • They’ll ensure that all legal arguments are valid, aligned with laws, and relevant to your situation.
  • They’ll protect your interests and rights throughout the process.

"Alton worked with me to create several documents for my independent (indie) video game studio. This included clauses about IP assignment, waiving rights, compensation, warranties, and so on. He worked diligently to turn 12 pages of my informal notes and intentions into a comprehensive package that diligently and accurately covers all the bases. It was a great experience overall, taking about two weeks of on-and-off discussion and revisions to understand the requirements of the documents; had I been quicker to respond, it likely would have been closer to a week. If you're working on a creative project where IP assignment and compensation need to be worked out, I recommend Alton for the job!"

"Anna revised our in-house created contract and made it so much better, quickly and with clear redline notes to answer questions and accept revisions fast and easy. All accomplished faster than I had requested. Offered insightful advice even in areas I had not requested but that could have cost me tens of thousands had someone not pointed out. I've never worked with a lawyer before and this was easy and stress free, I should have done it long ago. Will be working with Anna again if that is possible. Cannot say enough good things. I could have gone with her first draft with no revisions easily, and her explanations were very clear for each change."
