New Patent Public Search Tool from the United States Patent and Trademark Office (USPTO)

The United States Patent and Trademark Office (USPTO) has completed its transition to a new Patent Public Search tool (PPUBS), retiring several legacy tools. For those familiar with the legacy tools, the retired tools include: Public-Examiner’s Automated Search Tool (PubEAST), Public-Web-based Examiner’s Search Tool (PubWEST), Patent Full-Text and Image Database (PatFT), and Patent Application Full-Text and Image Database (AppFT). The new PPUBS tool is publicly available at

The new PPUBS tool allows users to search and download PDF copies of all U.S. patents and (published) patent applications. The tools provide for custom text searching and a wide variety of textual search strategies, such as wildcards, Boolean search terms, proximity operators, and field-specific search terms, can be used.

The PPUBS tool also includes several updates and upgrades to help users streamline patent searches. This includes user-friendly improvements such as a customizable modular data interface and the ability to add highlighting, tagging, and notes to organize the search data. Notably, the PPUBS tool also permits sorting the results by different data fields (e.g., title, date published, patent classification codes, applicant name) to quickly and efficiently locate US patents and patent applications of interest. Users can also quickly locate search terms within the text of any located US patents and patent applications. In addition, users can review forward and/or backward citations related to a specific US patent or patent application. These citations may provide useful insight into other patents or patent applications of potential interest.

The PPUBS tool is an invaluable tool that can be incorporated into any patent search strategy. Moreover, the tool is accessible to anyone conducting patent searching tasks. If you have questions regarding the USPTO’s new PPUBS tool, please contact your attorney at Andrus Intellectual Property Law.

Your attorney at Andrus Intellectual Property Law can also provide training for how to use the PPUBS tool, implement internal patent search strategies, and/or initiate formal professional patent searches performed by Andrus, such as patentability searches, clearance searches, and landscape/competitive monitoring searches.
