Trademark Disputes
Trademark disputes are legal battles that directly threaten corporate brand identity and market trust. Unauthorized use of similar trademarks causes consumer confusion and dilutes brand value; conversely, failing to properly respond to groundless trademark infringement assertions can lead to business suspension or enormous liabilities for damages. Trademark law is a field where various elements such as distinctiveness, similarity, and the scope of designated goods/services interact complexly, requiring specialized analysis and response strategies. LEE & MOCK IP’s trademark dispute team consists of patent attorneys and legal experts well-versed in trademark law and the Unfair Competition Prevention Act who collaborate closely to precisely analyze trademark similarity and the scope of rights to formulate optimal dispute strategies. We systematically respond to global trademark disputes through networks with local law firms, as well as procedures before the domestic IPTAB and courts.
