The USPTO offers a wide range of intellectual property (IP) resources, including application assistance, education and training, and other services that support the full spectrum of customers—from independent patent and trademark filers, to attorneys and business advisors in both the private and public sectors.
Many other databases also index United States patents and applications. If your intent is to conduct a thorough patent search, you should always search multiple databases, as no database will offer 100% coverage.
Provides USPTO patent examiners, applicants, attorneys, agents, and representatives of applicants with a reference work on the practices and procedures relative to the prosecution of patent applications before the USPTO.
The largest public patent database on the internet, Espacenet contains 100 million patent documents from more than 90+ countries including Canada and the U.S., plus 2 million records for non-patent literature cited in European Patent Office search reports.
All U.S. utility patents and published patent applications are indexed with CPC codes. Only Espacenet provides a platform for searching the CPC system. The USPTO does not currently allow for searching, though users can browse the system.
You cannot get a patent if your invention has already been publicly disclosed. Therefore, a search of all previous public disclosures, foreign patents and printed publications should be conducted. This tool was designed to help you get started.
The searchable documents in this release contain all the pre-grant U.S. utility patent publications from 1/1/2001 to 4/30/2020. The Utility figures/drawings search is based on the same collection. No searchable non-US patent applications or Non Patent Literature (NPL) are available in this release. More documents will be added into the collection into future release.
