The Official Gazette for Patents is published each Tuesday in electronic form only, and contains bibliographic (front page) text, a representative claim, and a drawing (if applicable) of each patent issued that week. Please note that the Official Gazette Notices are also included in each issue and provide important information and changes in rules concerning both patents and trademarks.
The most recent 52 weekly issues of the OG for Patents are available to view online using the issue date links below. These issues may be browsed by classification or type of patent, e.g., utility, design, and plant. Specific patents may be accessed by classification or patentee name. For each patent displayed, you may click the "Full Text" button in the upper left corner to retrieve the full text of the patent from the USPTO Full Text database. See usage notes within each issue or refer to the Frequently Asked Questions for additional information.
In addition, all of the issues published since July 2, 2002 can be downloaded from: Patent official gazettes (JUL 2, 2002 – present). The USPTO has not digitized the OG Gazette issues published before 1995. We do have an almost complete set of physical copies from January 1872 to September 2002 in our Public Search Facility here in Alexandria, VA.
Information on each patent may also be found in the comprehensive, searchable patent full-text, and full-page image databases, which are updated for each weekly issue and accessible directly from the home page of the USPTO Web site.
Trial Certificates published after January 18, 2018, will no longer display patent owner and petitioner data. The change in the composition of Trial Certificates makes the data published consistent with data published in Reexamination Certificates and simplifies the publication process.
