Invalidation Declaration
Invalidation (petitioning to void an already-registered mark). Applies when: someone squatted your brand in bad faith, the mark conflicts with your well-known trademark (an officially recognized nationally famous brand — a very high bar, not for ordinary brands), or registration was obtained by fraud or other improper means. Relative grounds must be raised within 5 years of the mark's registration.

FAQ
Is there a time limit for invalidation?
On relative grounds (prior rights or interests), it must be filed within 5 years of the disputed mark's registration. Bad-faith squatting of a well-known mark is exempt from the 5-year limit, as are absolute grounds (e.g. prohibited signs — state names, flags, deceptive signs — that cannot be registered).
My brand was squatted — can it be invalidated?
There's a chance. You must prove prior use with some influence and the other side's bad faith. We run a legal analysis first; if evidence is weak we say so honestly rather than filing blindly.
Invalidation vs opposition?
Opposition targets a published but not-yet-registered mark (currently a 3-month window, 2 months from Jan 1, 2027); invalidation targets an already-registered mark. Miss the opposition window and invalidation is usually the only route — at higher cost.
Any remedy if the ruling disappoints?
Yes. Unhappy with the review ruling, you may file an administrative lawsuit in court within 30 days of receiving it. We advise on whether to sue when the time comes.
What do I need to do?
Provide proof of prior rights plus use and reputation evidence, and check/sign the application. The stronger the evidence the better the odds — drafting, filing and follow-up are on us.
