Trademark Infringement Identification Standards and Enterprise Enforcement Strategy

Trademark infringement is the most common legal issue in enterprise brand protection. Accurately understanding infringement identification standards helps enterprises enforce rights promptly or mount reasonable defenses.

1. Infringement Elements

Trademark infringement requires all of the following: use without the trademark registrant's permission, use on identical or similar goods/services, a mark identical or similar to the registered trademark, and likelihood of confusion. "Likelihood of confusion" is the core standard, including source confusion and affiliation confusion.

2. Similarity Assessment

Trademark similarity is assessed holistically across pronunciation, appearance, and meaning, using the general attention of the relevant public as the standard. Goods similarity references the "Classification Table of Similar Goods and Services," combined with factors such as function, purpose, production sector, sales channels, and target consumers. Well-known trademarks receive cross-category protection.

3. Legitimate Source Defense

A seller who does not know that goods infringe a registered trademark exclusive right, and can prove the goods were lawfully obtained and identify the supplier, is not liable for damages. Evidence of lawful source includes purchase contracts, invoices, payment vouchers, and supplier qualifications. However, sale of infringing goods must still cease.

4. Enforcement Path Selection

Enterprises may pursue: administrative complaints (market regulation authorities, fast), civil litigation (damages, may apply for injunctive relief), criminal reporting (serious cases constituting counterfeit registered trademark crime), and platform complaints (rapid takedown on e-commerce platforms). A combination approach based on infringement scale and evidence is recommended.
