Trademark disputes affect brand identity and market position. Whether defending your mark or accused of infringement, understand your legal standing.
Expert information to help you understand your rights and options
Trademark disputes arise when others use marks confusingly similar to yours—or when you are accused of infringement. Stakes include brand value, market position, and substantial legal costs. Learn how trademark disputes develop, enforcement options, and defense strategies.
Trademark infringement defendants can challenge confusion likelihood, assert fair use, prove abandonment, or attack registration validity. Many accusations stem from trademark bullying by aggressive owners. Learn defense strategies, when to fight versus negotiate, and potential counterclaims.
Cancellation proceedings challenge existing registrations based on abandonment, fraud, genericness, or prior rights. Cancellation is an alternative to or supplement for infringement litigation. Learn cancellation grounds, TTAB procedures, and when cancellation makes strategic sense.
Opposition proceedings let you challenge conflicting trademark applications before registration—often cheaper than post-registration litigation. The process resembles litigation before the TTAB. Learn opposition grounds, procedures, timing requirements, and strategic considerations.
Trademark infringement requires proving the accused mark creates likelihood of confusion with yours among relevant consumers. Courts consider multiple factors including similarity, market proximity, and actual confusion evidence. Learn how to build infringement cases and required proof.
