Notice of Publication
A written statement from the USPTO notifying an applicant that its mark will be published in the Official Gazette. If the examining attorney assigned to an application raises no objections to registration, or if the applicant overcomes all objections, the examining attorney will approve the mark for publication. The notice of publication provides the date of publication. Any party who believes it may be damaged by registration of the mark has thirty (30) days from the publication date to file either an opposition to registration or a request to extend the time to oppose.
If no opposition is filed or if the opposition is unsuccessful, the application enters the next stage of the registration process. A Certificate of Registration will issue for applications based on use or on a foreign registration under S44, or a Notice of Allowance will issue for intent-to-use applications.
