Trademarks are one of the most valuable assets in a business. They represent and guard your reputation, your brand identity, and the trust you’ve built with customers over time. However, securing a trademark does not mean you have hit the jackpot. In fact, it is just the beginning of an ongoing responsibility. Trademarks can be cancelled if certain legal requirements are not met, and even minor missteps by a business can put a trademark registration at risk. Let’s explore five mistakes that can lead to trademark cancellation and how to avoid them.

Mistake #1: Abandonment or Non-Use

One of the fastest ways to lose a trademark is by not using it. Under the Lanham Act, a mark may be considered abandoned if it is no longer used in commerce with no intent to resume use. If you do not use your trademark for three consecutive years, the law may consider it abandoned, which can lead to cancellation.

To avoid this, consistently use your mark in real business operations. This may include using it on your website, products, packaging, and marketing materials. If you wish to pause use, you may be able to file for “excusable nonuse”, although this is an exception and is not easily granted.

Mistake #2: Missing Maintenance Deadlines

The U.S. Patent and Trademark Office (USPTO) requires periodic filings to confirm that your mark is still in use. If you miss the deadlines for these filings, such as your Declaration of Use, it can result in cancellation, even if you are actively using the mark.

The solution here is quite straightforward: keep track of your deadlines. Many businesses work with business attorneys to ensure filings are submitted on time.

Mistake #3: Letting Your Mark Become Generic

If you don’t actively protect your mark, you risk losing it to generic use. This happens when the public starts using your brand name as a general term for products or services. To prevent this, monitor how your brand is used in the marketplace. If you spot any misuse, correct it immediately and ensure your own marketing treats the mark as a brand, not a product category.

Mistake #4: Lack of Bona Fide Use

Trademark law requires genuine commercial use of a trademark. This means that transactions, whether you are selling goods or services, must be real, not token efforts designed to secure registration. If your use is minimal, staged, or inconsistent with normal business practices, your registration may be challenged, or even cancelled.

To ensure bona fide use, make sure your trademark is related to actual, ongoing business activity. Also, remember that what qualifies as sufficient use can vary by industry, so it’s essential to align your use with your field’s standard practices.

Mistake #5: Fraud on the USPTO

Providing false or misleading information during the application or maintenance process can also lead to a trademark being cancelled. If a trademark owner knowingly submits inaccurate claims, such as stating use that doesn’t exist, the registration may be cancelled for fraud. Ensure every statement you make to the USPTO is truthful and supported by evidence. If you made an unintentional error, correct it promptly before problems arise.

Non-Use and Abandonment: Three Years Can Cost You Everything

The most straightforward way to lose a trademark registration is to stop using the mark in commerce. Under 15 U.S.C. § 1127, a mark is deemed abandoned when its use has been discontinued with intent to abandon, and nonuse for three consecutive years is prima facie evidence of abandonment. “Use in commerce” requires genuine use on goods in the ordinary course of trade or genuine use in connection with services—token sales made solely to maintain a registration do not qualify. Once abandoned, the registration is subject to cancellation through a proceeding at the USPTO’s Trademark Trial and Appeal Board (TTAB), and any party with a legitimate interest can file for cancellation.

Trademark owners who temporarily suspend operations—for example, during a product reformulation or supply chain disruption—should document the reason for non-use and the intent to resume. Courts have found that excusable non-use, supported by objective evidence of intent to resume use and concrete steps toward that resumption, can rebut the prima facie abandonment presumption. But “intent to resume” must be genuine and accompanied by affirmative action—it is not enough to declare your intention to restart a brand you stopped using years ago. If you anticipate a gap in use lasting more than 18 months, consult a trademark attorney about how to document and protect your rights during that period.

Filing False or Inaccurate Maintenance Declarations

Between the fifth and sixth anniversaries of registration, trademark owners must file a Section 8 Declaration of Continued Use, 15 U.S.C. § 1058, certifying that the mark is in use in commerce for each of the goods and services listed in the registration, with a specimen showing current use. A similar declaration is required at the ten-year renewal under Section 9. Filing these declarations with false or inaccurate information—certifying use of the mark on goods or services for which actual use has been discontinued, or submitting a specimen that does not reflect genuine use at the time of filing—constitutes fraud on the USPTO.

Fraudulent maintenance filings are a ground for cancellation at any time under 15 U.S.C. § 1064(3). The Federal Circuit standard for fraud on the USPTO, articulated in In re Bose Corp., 580 F.3d 1240 (Fed. Cir. 2009), requires proof that the applicant knowingly made a false, material representation of fact in connection with a registration, with intent to deceive the USPTO. A subjective good faith belief that the representation was accurate negates the fraud claim—but reckless disregard for the truth can satisfy the standard. The practical lesson: before filing any maintenance or renewal declaration, confirm that the mark is actually in use on every single goods and services item listed, and remove from the declaration any item for which genuine use cannot be proven.

Failure to Enforce: Acquiescence and Naked Licensing

A trademark owner who fails to enforce rights against known infringers risks acquiescence—a defense that can bar both injunctive relief and damages against those specific infringers. More broadly, a pattern of non-enforcement can contribute to a genericness finding if third-party use becomes widespread enough that the primary significance of the term to the consuming public is as a product category rather than a source indicator. Courts evaluate the mark owner’s enforcement history as part of the genericness analysis, and a documented pattern of allowing competitors to use the mark without objection is damaging evidence in any validity challenge.

“Naked licensing”—allowing others to use your trademark without exercising adequate quality control over the goods or services they provide under the mark—is a separate, severe trap. If a trademark owner licenses the mark to a third party without maintaining meaningful supervision over the quality of the licensed goods or services, courts treat the mark as abandoned because the trademark no longer functions to identify a consistent quality source. In FreecycleSunnyvale v. Freecycle Network, 626 F.3d 509 (9th Cir. 2010), the court found that a licensor’s failure to exercise quality control rendered the license “naked” and contributed to an abandonment finding. Any trademark licensing arrangement—including informal arrangements with affiliates, resellers, or business partners—must include contractual quality control provisions and evidence of actual oversight to avoid this risk.

Using a Mark on the Wrong Goods or Services

A trademark registration only protects the mark as used in connection with the goods and services identified in the registration. If your registration covers Class 25 clothing and you pivot to selling software, your software use is not protected—you would need a new application in Class 9 or 42. More subtly, if your registration describes your goods as “athletic footwear” and you expand to dress shoes and children’s shoes, use on those new categories may not be covered. A competitor who begins using a confusingly similar mark on dress shoes could argue there is no likelihood of confusion with your athletic footwear registration and that you cannot seek to stop their use.

Conduct periodic audits of your trademark portfolio against your actual commercial activities. As your business evolves—adding product lines, expanding into new services, launching sub-brands or licensing programs—compare each commercial activity to the description of goods and services in your existing registrations. Where there are gaps, file new applications to cover the new activities. Act quickly: filing an application now establishes a priority date that may predate any conflict that arises as your brand grows. Waiting until a conflict arises to file in a new class may mean competing with a party who filed earlier.

Failure to Oppose Conflicting Applications in Time

After the USPTO publishes a trademark application for opposition in the Official Gazette, anyone who believes they would be damaged by the registration has 30 days to file a Notice of Opposition with the TTAB. Missing this window forecloses the opposition remedy—you cannot oppose after the mark registers (though you can seek cancellation for three years on certain grounds). Trademark watch services monitor new USPTO filings and alert registered owners to potentially conflicting applications before they register. Without a watch service, you may not discover a conflicting registration until a competitor’s mark is already registered, strengthening their position and complicating your enforcement options.

TTAB opposition proceedings are adjudicatory proceedings that resemble federal litigation: parties exchange pleadings, conduct discovery, submit evidence, and brief legal arguments before a panel of administrative trademark judges. While less expensive than federal district court litigation, they are not trivial—a contested opposition can take two to three years and cost substantial sums in attorney’s fees. Early opposition, when the applicant has not yet built substantial goodwill in the mark, is generally more efficient than waiting and then suing for infringement years later when the stakes—and the defendant’s resources to fight—are much higher.
