Riot Games, Inc. v. Tang Xilin - TTAB Trademark Opposition

Riot Games, Inc. filed an opposition proceeding with the USPTO Trademark Trial and Appeal Board against Tang Xilin's trademark application. The TTAB subsequently issued a Notice of Default, indicating the applicant failed to respond to the opposition within the required timeframe. The opposition challenges the registration of the applicant's mark on grounds typically including likelihood of confusion or other grounds under the Lanham Act.

Affected parties in TTAB opposition proceedings should ensure timely responses to opposition pleadings to avoid default judgments. Trademark applicants facing opposition must actively defend their applications through the TTAB process, including filing an answer and potentially a counterclaim. Default judgments in TTAB proceedings typically result in the registration being refused and the applicant's rights being limited without further opportunity to contest the opposition.
