TradeMark Express says trademark checks should be repeated every few years

TradeMark Express is warning business owners that a one-time trademark search can leave them exposed to conflicts they could have found earlier. The Los Altos firm says repeat checks can also help preserve the ability to enforce rights later under laches.

Why it matters: - Trademark availability can change after a business picks a name but before it files an application. - Failing to recheck later can weaken a business's ability to challenge a similar mark if a court decides the conflict should have been found earlier. - Common law rights can be limited by geography, while federal registration at the U.S. Patent and Trademark Office can provide broader national protection.

What happened: - TradeMark Express, a Los Altos trademark research and application preparation firm founded in 1992, urged business owners to treat trademark research as a recurring process. - The company said trademark clearance should happen three times: before a name or logo is finalized, again before filing if that was not done at the same time, and then about every two to three years afterward. - Chris DeMassa, founder of TradeMark Express, said a business can do everything right at the start and still face trouble years later if it never checks again.

The details: - The first two searches are meant to reduce the risk of choosing a name that conflicts with an existing mark. - The third search is meant to support future enforcement under laches, a legal doctrine that can penalize delays in objecting to a similar name. - Under laches, a court can treat the delay clock as starting when the conflict reasonably should have been found, not only when the business actually noticed it. - TradeMark Express said basic internet searches, AI tools and the USPTO database often miss names that are not identical but are still too close legally. - Those misses can include names that sound alike, look alike or cover closely related goods or services. - TradeMark Express also said its experience shows many businesses overlook unregistered names that may still have common law rights. - DeMassa said the strongest businesses have a trademark search done before choosing a name, before filing and every couple of years after that.

Between the lines: - The warning goes beyond clearance and points to enforcement strategy. - A business may believe it is safe because it did not know about a conflict, but courts may still expect it to have found the issue through a reasonable search. - The message also pushes owners away from treating trademark research as a startup-only task. - Federal registration remains the stronger legal tool, but registration does not replace ongoing monitoring.

What's next: - TradeMark Express said business owners who want more information can contact the company directly. - The firm, which has provided trademark clearance research and application preparation since 1992, said it has been referenced in Nolo Press trademark guides since 1994. - TradeMark Express said it is not a law firm and does not provide legal advice. - The company also pointed readers to its social media channels, including LinkedIn, Instagram, Facebook, YouTube, X and Calendly.

The bottom line: - Trademark searches are not just about launch-day clearance; they can also shape how well a business can defend its name years later.
