Patent and trademarks

As a Patent and Trademark Resource Center (PTRC) member, the Hawaii State Library has access to the same tools used by U.S. Patent and Trademark Office patent examiners.

The online tools include PubEAST and PubWEST, which have many advantages over the online patent databases available at

Benefits include:

  • Save time and money through faster and more powerful patent searches
  • Allow text searching for U.S. patents issued from 1920 up to the most recent weekly updates
  • Foreign patent abstracts and documents
  • Support more complex boolean, field and proximity searching
  • Multiple databases can be searched simultaneously if databases have common fields

However, patents issued from 1790 to 1920 are searchable only by patent number, issue date and classification.


PubEAST and PubWEST include the following databases:

USPAT: United States Patents

  • Full text search for the US patents, 1971 to present.
  • Patent number, publication date and current classification search only for pre-1971 US patents back to 1790 PGPub: Pre-grant publications
  • U.S. utility patent applications that have been pending for 18 months USOCR: US Optical Character Recognition
  • US patents issued between 1920-1970 plus those from 1971-1976 that are missing from USPAT file

EPO: European Patent Office

  • English language abstracts of European Patent Office (EPO) and World Intellectual Property Organization (WIPO) documents
  • Full text of U.S. patents since 1790

JPO: Japan Patent Office

  • English language abstracts of Japanese patent applications from October 1976 FPRS: Foreign Patent Retrieval System
  • English abstract of EPO, JPO, and Derwent files, plus foreign patent images.

PubEAST features BRS for text and IS&R for number searching, easy customization of display formats, tagging records, and fast browsing capabilities with the potential to save 50% of search time.

PubWEST offers structured searching for novice users as well as freeform searching for advanced searchers. It is a server-based gateway to access the same databases as PubEAST with easy downloading options. PubEAST and PubWEST will also be available at Lihue Public Library and Kahului Public Library.
