The USPTO issued an update on August 6, 2025. In this announcement, it terminated over 52,000 trademark applications and registrations linked to a foreign filing firm. Additionally, the PTO issued sanctions against the firm, Shenzhen Chenhaiyun Tech Co. Ltd, and its subsidiaries. Collectively, they were known as “Seller Growth”.
According to the PTO, the firm submitted documents without proper authority.
Specifically, it sought out U.S. licensed attorneys, misused their credentials, and faked their electronic signatures. Furthermore, the firm repeatedly signed documents using other people’s names. It also submitted fake specimens of use and misused USPTO.gov accounts.
