Representative Cases

We deliver results. The following anonymized case studies highlight how we help our clients protect their intellectual property and commercial interests in China:

Blocked $5M+ Worth of Counterfeit Exports at Chinese Customs

On behalf of a U.S.-based company, we investigated a contract manufacturer in China suspected of infringing the client's invention patent. Our in-house investigation team successfully identified the source manufacturer. We worked with Chinese Customs to intercept and block over $5 million worth of infringing goods from being exported to the United States. The client ultimately prevailed in a Chinese court.

Removed Over 10,000 Infringing Listings on Major E-commerce Platforms

A global brand engaged us to address widespread online infringement of its patented products sold on Chinese e-commerce platforms. We executed a comprehensive enforcement strategy involving platform takedown requests, legal demand letters, and civil litigation. As a result, we successfully removed more than 10,000 infringing listings.

Secured Annual Patent Royalties Through Covert On-Site Investigation

A client retained us to stop a Chinese manufacturer from producing patented products without authorization. Our investigation team embedded an undercover investigator within the target company for over three months, mapping out production schedules and identifying the infringing production lines. In coordination with local regulators, our legal team conducted a surprise on-site inspection and preserved key evidence. The case concluded with a favorable settlement: the infringer agreed to pay an annual patent royalty of no less than RMB 800,000.
