Patent Public Search tool – a streamlined way to search all U.S. published patent applications

Blog by Andrew Faile, Acting Commissioner for Patents, and Jamie Holcombe, Chief Information Officer

Patent Public Search tool

“The new search interface for Patent Public Search looks really nice. We’re enjoying playing with new features!”

“The work you have done on the new public search system is top notch… it saves a lot of time while improving the search results I am able to obtain… Very impressive work.”

“Looking forward to using this new tool for my upcoming patent applications.”

As part of our ongoing effort to modernize and streamline our systems, earlier this year, we unveiled an all new Patent Public Search (PPUBS) tool. PPUBS is a free online search tool for all U.S. published patent applications and patent grants. Currently, approximately 4,500 users are conducting patent searches with PPUBS each day in the U.S. and internationally, and close to 350,000 people have used PPUBS since it launched. Based on the success and positive feedback we’ve received on PPUBS – with a few testimonial examples listed above – it will officially replace our legacy systems this September.

With the launch of PPUBS, you can now search the text of all published U.S. patents and U.S. Pre-Grant publications (PGPubs) remotely in one streamlined system. Previously, in order to conduct a similar search, you needed to visit a USPTO facility like our headquarters in Alexandria, a regional office, or a Patent and Trademark Resource Center. That also meant using one of four legacy systems: 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).

We developed PPUBS based on the current internal tool used by patent examiners, Patents End to End Search (PE2E-Search). Some similar features include highlighting, efficient tagging, and advanced notes for searching, analyzing, and managing patent data.

Some additional benefits of PPUBS include:

• Layouts: Multiple layouts and tools allow you to view more data at once and perform more precise searching.
• Highlighting: Multi-color highlighting allows you to easily sort and categorize your search results.
• Tagging: Document tagging allows you to group, rename, or color code your search results, helping you better organize your data.
• Notes: More advanced notes allow you to include tags, relevant claims, or other useful details.
• Quality: Robust full-text searching of U.S. patents and published applications improves the quality of your search and provides enhanced access to prior art.
• Familiar usability: If you previously used PubEAST and PubWEST, you will find that PPUBS has similar familiar searching options.

We are holding a number of regular training sessions on PPUBS – including webinars for novice searchers and advanced searchers. To view upcoming public training sessions, visit the events page of the USPTO website. We also offer training materials, quick reference guides, frequently asked questions, and a help center on the Patent Public Search webpage.

Your feedback is important to help us identify any issues with PPUBS and to determine features we may want to add or improve. If you have questions about Patent Public Search, please contact us. We are confident the new, powerful, and flexible capabilities of PPUBS will improve the overall patent searching process. If you aren’t already using it, we hope you’ll try it soon! 


Patent Public Search looks like it could be very valuable but certainly is not user friendly or intuitive in the absence of training. The Director's blog says that you are holding webinars but I saw none on the Events page which goes to December 1. The available materials look nice but are quite inadequate. When will a training webinar be available? The sooner the better.

Mr. Foster, USPTO has a Patent Search Training Program hosted online August 30, 10-11:30am Central on the USPTO Events Page: The USPTO Midwest Regional Office oversees outreach to Ohio. We would be happy to talk to you directly about search, or perhaps work with a local bar association. Please feel free to contact me directly for more info. Damian Porcari

I don't want to use the new search system. Please don't retire the legacy systems. I know how to use them and they work perfectly for me, so I don't want to waste my time learning the new system.

On August 18 and 19, webinars will be offered on the Patent Public Search tool. For more information, including future training dates, visit the following: the USPTO Events page: or the Patent Public Search series page:

The new system upgrade will be difficult for so many people to migrate to. Using the new search system will be difficult for me. Please do not retire the legacy systems yet. Personally, the Legacy system is working perfectly fine for me. I won't want to start learning how to use the new system please.

Are there youtube or other video webinars that show what Patent Public Search is and how to search it? It is not intuitive at all and a visual training session that I can watch at my leisure (repeatedly) would be appreciated. Thanks. Mike W.

New Public Search options are limited when it comes to downloading results. No hyperlinks to full text patents to share. Command searching goes back to early 80s. Is there a way to combine search results or eliminate certain search results?

I enjoyed using my iPad to do patent searches on the legacy systems. Since I use safari, the results no longer show on the new patent public search. I have to go to my PC and use chrome to do these searches. Any plans to also add safari? Many times the results do not show up due to browser closing the pop ups. Have to manually go and allow to pop ups. Can we make the experience more seamless?

The new search is like a cruel joke, at least to laymen inventors. What was relatively easy and straightforward now requires "training materials." Who wanted this?

You are too generous with your self-praise. No one felt the need for overly interactive pages. I recommend you let dead things be dead. Since you are so certain about the quality and welcome of this new search tool, there is no harm keeping the old Public Pair online, and leave those of us who have no time to attend to your intrusion to use the old Public Pair in peace.

Thank you for your feedback @Debashis ghosh! We don’t currently have plans to add Safari but will keep this in mind as we work to improve our system. We do plan to further simplify the design to improve the user experience on mobile devices. To address pop-ups, you can adjust your browser settings under “Privacy and security” in Chrome, or under “Cookies and site permissions” in Edge. If you have further questions, please email us at
