Summary

The USPTO Trademark Trial and Appeal Board sustained opposition TTAB91303117, preventing registration of the 'SERTESCAT' trademark by defendant Jiahu Wang. The opposition filed by Caterpillar Inc. on November 14, 2025, was successful, with the Board issuing its decision on April 3, 2026.

What changed

The TTAB sustained Opposition No. TTAB91303117, ruling in favor of Caterpillar Inc. and against applicant Jiahu Wang regarding the 'SERTESCAT' trademark. The Board's decision prevents the registration of the contested mark. This proceeding was handled under standard TTAB opposition procedures with no new regulatory obligations created.

This is a standard trademark adjudication with no broader compliance implications for the regulated community. Trademark applicants and registrants should ensure their marks do not conflict with existing registered marks to avoid similar opposition proceedings. Parties dissatisfied with TTAB decisions may seek review at the U.S. Court of Appeals for the Federal Circuit.
