Trademark infringement defense lawyer
If you are facing a trademark infringement claim, start by reviewing the asserted mark, its registration details, and how your business actually uses the name, brand, or logo at issue.
Trademark disputes can go beyond a demand letter. Depending on the stage, the matter may involve USPTO examination, appeal, opposition, cancellation, or a related domain name conflict.
In brief
- Review the trademark registration, the listed goods or services, and the actual use being challenged before deciding how to respond.
- Check the procedural stage carefully. A USPTO examination or appeal is different from an inter partes dispute such as an opposition or cancellation.
- If the other side's registration appears overbroad or not supported by real use, expungement or reexamination may be relevant in some situations.
What to do
A practical trademark defense starts with the record. That means comparing the asserted mark, the registration status, and the identified goods or services against actual marketplace use. If the issue is tied to a USPTO filing, it also helps to know whether the matter is still in an ex parte stage or has become a dispute between parties.
Procedure matters. In USPTO practice, office actions, responses, and ex parte appeals follow a different path from opposition or cancellation proceedings. Once a trademark matter becomes inter partes, the posture changes, and the response usually needs to address an active dispute rather than only communication with the USPTO.
In some matters, the defense is not limited to answering allegations. It may also involve evaluating the strength of the other side's registration, including whether all claimed goods or services are supported by actual use. Expungement and reexamination can matter when a registration covers goods or services the owner is not using.
What to keep in mind
Not every trademark conflict is the same. Some issues arise when choosing and clearing a mark early, while others begin after enforcement starts or a registration is challenged. The right approach depends on the filing posture, the scope of the registration, and the facts around actual use.
Trademark disputes can also overlap with domain name problems. For domain-related trademark conflicts, UDRP and ACPA are different paths. UDRP is often used when speed and cost matter, while ACPA may be considered when transfer or damages are part of the objective.
A careful defense usually turns on specifics such as the mark being asserted, the goods or services listed in the registration, whether use supports those listings, and whether the matter is before the USPTO or in a more adversarial setting. General information helps, but the facts drive the response.
