Official Gazette (OG)

The Official Gazette, or the OG, is a weekly publication from the United States Patent and Trademark Office. The primary purpose of the Official Gazette is to notify the public of the Patent and Trademark Office's intent to register a trademark.

After the Patent and Trademark Office publishes the intent to register a trademark in the Official Gazette, there is a 30-day opposition period. The opposition period is a time during which anyone who believes registration of the trademark would cause them harm may notify the Patent and Trademark Office by filing an opposition.

If the 30-day opposition period passes without the Patent and Trademark Office receiving an opposition, the Patent and Trademark Office will send a Notice of Allowance to the applicant notifying them they may proceed with the trademark registration process.
