The U.S. Patent and Trademark Office (USPTO) Trademark Trial and Appeal Board (TTAB) has issued a Notice of Default in opposition case TTAB91304258. This action stems from an opposition filed by KOUKEYAN HOLDINGS LLC against the trademark RENU FRESHFUR, owned by Haoyan Liu. The notice indicates a default judgment, suggesting the defendant failed to respond to the opposition proceedings initiated on January 5, 2026.

This default signifies a significant development in the trademark opposition. Legal professionals representing parties in TTAB proceedings should note the implications of a default judgment, which typically results in the cancellation or denial of the opposed trademark application. While no specific compliance deadline is stated, the default itself implies a failure to meet procedural requirements. The TTAB's decision is binding on the parties involved in this specific dispute.
