Notice of Opposition under Section 21 of the Trade Marks Act
The four-month opposition window is non-extendable. A notice that mis-cites the section, mis-describes the cited mark, or mis-files the form is a notice that does not exist for the Registry.
Introduction
Trademark opposition is procedural before substantive. Four months from advertisement, non-extendable, Form TM-O mandatory, grounds with specific sub-section references. A well-drafted opposition is the difference between a registration to live with for ten years and one refused at threshold.
