UK & EU Trademark Invalidation

No matter how diligent you are as a trademark owner when it comes to monitoring your trademark or brand, on some occasions, trademark applications can slip under the radar, leading to somebody successfully registering a trademark that you would have opposed.

This happens to every trademark owner, large and small at some stage in their business journey, which is why the invalidation process exists to help protect your brand.

Let’s talk about how our Trademark Invalidation Services can help you to enforce your trademark rights.

What is a Trademark Invalidation?

When you discover that the UK IPO or the EU IPO have registered a trademark which looks like, sounds like or is spelled like yours, trademark invalidation is the legal procedure we follow to challenge the validity of the registered trademark. Our goal being to enforce the partial or full removal of the trademark from the official register.
Whether you are challenging someone else’s trademark or defending your own trademark, this is where expert guidance like ours can be key to ensuring the best possible outcome.

How Does a Trademark Invalidation Differ from a Trademark Opposition?

Whilst both involve disputes over trademarks, they occur at different stages in the trademark lifecycle:

  • Trademark Opposition: This happens before a trademark is officially registered so early detection is key. Opposition means challenge a trademark during its application stage, the aim being to prevent the trademark from being registered at all.
  • Trademark Invalidation: This takes place after a trademark has been registered. Invalidation allows for the removal of an already registered trademark on specific grounds, such as prior rights, bad faith, or a lack of distinctiveness.

Put simply, you can oppose a trademark before it is registered, and you can try to invalidate a trademark after it having been registered.

What reasons can you give for invalidating a trademark?

If you believe a trademark should never have been registered, whether because it conflicts with your earlier rights or because it was filed in bad faith, we can help you file for invalidation.

The most common grounds for invalidation are:

  • Earlier Rights: If you own a prior trademark or have been using a similar mark before the one in question was registered.
  • Lack of Distinctiveness: If the trademark is too generic or descriptive and doesn’t provide a unique identity in the marketplace.
  • Bad Faith: If the trademark was registered with dishonest intentions, such as to prevent rightful use by others.


At The Trademark Helpline, we assist clients in preparing and filing invalidation applications, helping you gather the necessary evidence and craft a solid case for challenging the trademark.
