When the United States Patent and Trademark Office (USPTO) intends to issue a patent, it sends the applicant a Notice of Allowance. For this to happen, an inventor provides information such as product description, design, and blueprints or drawings.
The USPTO trademark attorney will send a Notice of Publication to the applicant stating the date of publication. Any party who believes it may be damaged by registration of the mark has 30 days from the publication date to file a Notice of Opposition or a Request to Extend Time to Oppose.
