Opposing a Trademark Application

Every week the United States Patent and Trademark Office publishes a list of trademark applications that they have approved for registration. There is a thirty day period after publication during which a third party may either oppose registration, or ask for an extension of time to oppose.

It’s common for someone with a competing mark to ask for an extension of time to oppose, either to evaluate whether they’d like to file an opposition, or to negotiate with the applicant to modify the application to avoid potential confusion with customers.
