What you can do with it

Search by what it does

Describe the invention in your own words and find the filings that match, even when they use completely different terminology.

See the landscape

Who is filing, in which offices, and how a field has moved year on year.

Follow it into the record

Every result links back to the office's own publication, so a claim can be checked at source.

Read alongside the research

Patents sit next to the academic corpus, so an invention and the papers behind it turn up in the same search.

Where it’s used

Research

The research workspace reads patents alongside papers, standards and datasets, with citations that link back to the original filing.

Patents are one of several reference collections in the wider askFinz index — see the full how the index works for how a filing gets from the office's own publication into a search result.
