TTAB
A second PET-AGREE filing did not escape the first Board loss
On September 16, 2026, the Trademark Trial and Appeal Board sustained Opposition No. 91263504 on Mars, Incorporated's claim preclusion claim against Serial No. 88767940 for PET-AGREE GROOMING SUPPLIES, after Mars won a non-precedential opposition against PET-AGREE in 2019. This opinion states that it is not a precedent of the TTAB. It does not decide likelihood of confusion or dilution.
