Trademark Opposition

A trademark opposition is a challenge filed by a third party after your mark is advertised in the Trade Marks Journal, via Form TM-O. It is the longest branch of the prosecution chain, often 2–3 years.

Anyone may oppose within 4 months from advertisement in the Trade Marks Journal. If opposed, you must file a counter-statement within 2 months — no extension — this deadline cannot be extended, and missing it means the application is deemed abandoned.
