An Introduction to PatBase Express

PatBasics Express - Search

Searching with PatBase Express



  • Searching in PatBase Express is run using one of our specialised forms, accessible either along the top toolbar or under More options.
  • Run simple searches to start working with documents immediately using the Basic search form, searching by keywords or inventor/company names.
  • Search forms have two checkboxes at the bottom of the form. To search all fields with the same publication, tick the corresponding checkbox. If you would like to search across all original and machine translated text, tick the checkbox titled Include machine translations.
  • Search by numbers using the Number search form, allowing you to retrieve documents by searching publication, application (US serial numbers allowed) or priority number.
  • Already have a copy of what you’re looking for? Use the Semantic search to paste text snippets of relevant documents and retrieve similar patents. These actions are accessible from the toolbar and when viewing a patent (option found to the right-hand side of the screen when viewing, in-line with the master patent number).
  • For more complex queries, Advanced search allows you to define and combine your criteria however you want, with dropdowns to pick the Boolean operators and search fields of interest, allowing you to be as broad or specific as required.
