HAI NAN GUANGSHENGYUAN TECHNOLOGY CO. LTD. filed a trademark cancellation proceeding (TTAB92090699) against CHEN, Xiaohua regarding the TKTX mark, with a filing date of January 23, 2026. The TTAB issued a Notice of Default on April 4, 2026, because the defendant failed to file an answer or otherwise respond to the complaint within the required timeframe under Trademark Rule 2.114(a).

The defendant now faces potential entry of default judgment, which could result in cancellation of the TKTX trademark registration. The plaintiff should monitor the proceeding for any motion to set aside the default. Other trademark registrants facing similar opposition or cancellation proceedings should ensure timely responses to avoid default judgments and loss of trademark rights.
