Better tools for working with patent information

Patent databases contain a wealth of technical information, but finding the right records can be difficult. These projects explore ways to retrieve relevant documents, organize the results, and provide useful context for AI-assisted analysis.

01 — Find the relevant records
Search public office-action text across patent applications to find relevant correspondence and reasoning.
02 — Follow the source
Research should stay connected to its underlying records so readers can check the documents and assess the conclusions.
03 — Focus the results
Group results by application and focus them by examiner, art unit, and document type.
04 — Make data use clear
Requests go directly from your browser to the USPTO and, if you request a summary, to your selected AI service.

Data

Working with public patent data

Office Action Text Search uses public patent prosecution records from the USPTO. Its focus is office action text and the information that helps researchers locate and organize those documents.

Searches request records directly from the USPTO Open Data Portal. Details about data sources, limitations, and update dates will accompany each published tool or report.

Current site features
Use your own keys to search and optionally request AI summaries. There are no website accounts or contact forms. See the privacy notice for details.

Selected findings, supporting data, and explanations of the research methods will appear here as they are prepared for publication.

About

Why this site exists

Public patent file histories offer a detailed record of prosecution practice. Searching and interpreting those records at scale can still be difficult, particularly without specialized tools or programming experience.

AI Patent Tools is a collection of projects, data, and results built while trying to make that work more approachable. It explores the use of browser tools, structured retrieval, and AI-assisted analysis in patent research.

The site is maintained by Todd Breuer, a patent attorney. New material will be added over time, with the status and limitations of each project explained alongside it.
