Avoiding Loss of Trademark Rights

Time, money, and effort go into building a trademark. A federal registration does not finish the job. Rights can still be lost, narrowed, or made harder to enforce. These are the problems that come up most often.

1. Failure to use the mark

Trademark rights depend on use. If you stop using the mark and do not intend to resume use, the mark can be abandoned. Nonuse for three consecutive years can support a presumption that the owner does not intend to resume use. Once a mark is abandoned, those rights are gone. Keep using the mark as a brand on the goods or services it identifies, and keep specimens you can use for USPTO maintenance filings.

2. Uncontrolled licensing

You can license a mark. You cannot hand it over and walk away. Trademark law gives the owner exclusive rights in exchange for a consistent signal of source and quality. If licensees use the mark on goods or services you do not police, the license can be treated as a naked license. That can support cancellation or a finding that the owner no longer controls the mark. Written licenses should include quality standards and a practical way to monitor them.

3. Failure to enforce

You do not have to sue every infringer. Repeated, knowing tolerance of confusing uses can still shrink what you can stop later. The registration may remain on the Register, but the mark becomes harder to enforce against similar names in the same field. Monitoring, letters, coexistence agreements where appropriate, and TTAB or court action when needed all help keep the scope of the mark from quietly eroding.

4. Generic use

A mark is lost if the public comes to treat it as the common name of the product or service rather than as a brand. Historical examples include aspirin, escalator, and linoleum. Use the mark as a brand, not as the name of the thing itself. Prefer “X brand coffee” over “an X.” Correct generic use by employees, licensees, and the press when you can.

Practical maintenance

Use the mark continuously on the goods or services in the registration
Calendar Section 8 and Section 9 deadlines
Keep current licenses and quality-control records
Watch for conflicting applications and marketplace uses
Do not use ® unless the mark is registered

If you are unsure whether a mark is still being used correctly, licensed correctly, or enforced consistently, it is cheaper to review the portfolio before a deadline or a dispute forces the issue.
