RAPID LABS Opposition: Siemens Healthcare Diagnostics Inc. v. Rapid Labs Limited
Summary
Siemens Healthcare Diagnostics Inc. filed an opposition against Rapid Labs Limited's RAPID LABS trademark application (TTAB Proceeding No. 91305201) on February 13, 2026. The TTAB issued a Notice of Default after Rapid Labs Limited failed to file an answer or otherwise respond to the opposition within the required timeframe. A Notice of Default is a procedural step that precedes entry of judgment against the defaulting party and does not itself determine the merits of the opposition.

What changed
The TTAB issued a Notice of Default in Opposition No. 91305201, finding that defendant Rapid Labs Limited failed to timely answer or otherwise respond to Siemens Healthcare Diagnostics Inc.'s opposition to registration of the RAPID LABS mark. This procedural default does not adjudicate the merits of the opposition but clears the path for the TTAB to enter judgment in favor of the plaintiff. The opposition remains pending until the Board enters final judgment.
Affected parties — particularly Rapid Labs Limited — should be aware that default judgments in TTAB proceedings are difficult to reverse and typically require a showing of excusable neglect and prompt action. Siemens Healthcare Diagnostics Inc. benefits from this procedural step as it advances toward a final determination blocking registration of the contested mark.
