Trademark opposition is a legal tool that lets others voice concerns about a new trademark getting registered. This is done to make sure only unique and non-confusing trademarks get the green light for protection. It’s a way to look out for both current trademark owners and the public.

Anyone can oppose a trademark that’s been published in the Trademark Journal. To do this, they need to file the opposition with the Trademarks Registry, the same place where the application for trademark registration is submitted.
