Trademark opposition is a legal challenge against the registration of a specific trademark. It commences by submitting a notice of opposition within 3 months of the trademark application’s publication for opposition. This step follows the registrar’s approval and publication of the trademark in a journal, allowing third parties to object.

Once a trademark is opposed, an opposition proceeding is initiated, involving both parties in negotiations to reach a mutually acceptable decision. This process aims to resolve disputes and ensure fairness for all parties involved in the trademark registration process.
