Find any patent: by number, plain language, or fielded query.
Search 20M+ patents and publications by number, keyword, assignee, or a plain technical description, or let Ursa turn a research goal into a structured, fielded query.
How to get there
Use the search bar in the top nav (it's on every page) or the big search on the home page.
Search by number
Look up a patent, publication, or application from one box. It detects the identifier type for you and autocompletes as you type.
Open advanced search
Click the + beside the search box to open advanced search: keywords, fields, citations, and filters in one structured query.
Combine keywords, fields, and filters
Build a structured query: keywords across Title, Abstract, Claims, or Spec, plus patent citations and assignee / inventor / date filters (over grants, publications, and articles).
Let Ursa build the search
Tell Ursa your goal in plain language; it proposes keywords, assignee/inventor filters, dates, search types, and fields before running anything.
Review, edit, and set the date range
Retry, edit the prompt, or adjust the fields and the from / through dates, then run the search from the form.
Read the results
Scan result cards with snippets and citations; patents, publications, and articles are clearly distinguished.
Search within results, sort, and filter
Narrow a result set, order by relevance or date, and filter down to what matters.
Run a bulk identifier search
Paste a mixed list of patent, publication, and application numbers and look them all up: all, grants, publications, or applications.
Open a patent and start working from the record.
Search a patent, read the claims, check the support, and keep the work in Patent Bear instead of rebuilding it across tabs.
