Inventor Search Assistance Beta
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.
