What Derwent Patent Search is

Derwent Patent Search is a cloud service for patent professionals assessing patentability, freedom to operate, and validity. Its search combines keywords, more than 300 searchable fields, and AI Search, which accepts natural-language descriptions and uses a large language model trained on DWPI. The service provides descriptive titles and abstracts for more than 70 million invention families, summarizing novelty, use, and advantage.

Patent coverage includes enhanced full-text data from 76 jurisdictions and bibliographic data from 109, spanning more than 178 million publications. It also correlates litigation cases from more than 140 jurisdictions, with histories and case details, and includes scientific literature from more than 13,500 journals evaluated by the Web of Science editorial team. Users can build and manage complex searches and use analysis tools for claims and patent families, plus portfolio tracking, deadlines, renewals, and filing management. Pricing is available by contacting Clarivate or booking a demo; a free trial can be requested by form.
