Derwent Patent Search (formerly Derwent Innovation)

Introduction

Derwent Patent Search (formerly Derwent Innovation) is Clarivate's flagship patent search and analytics platform, built on the Derwent World Patents Index — a curated patent database with roots going back decades and now part of Clarivate Plc (NYSE: CLVT), a publicly traded information-services company headquartered in London and Philadelphia. The platform gives patent attorneys, IP counsel, and R&D teams full-text search across 178 million+ patent publications from 109 jurisdictions, backed by 70 million+ invention families with expert-authored summaries. Clarivate rebranded the product from "Derwent Innovation" to "Derwent Patent Search" and added an AI Search feature that uses large language models trained on Derwent's own curated patent index to surface more relevant prior art. Customers referenced on Clarivate's own product page include Asahi Kasei, Boston Scientific, and Ehrlich Group.

Legal Research

Derwent Patent Search is a specialized patent-research tool rather than a general legal-research platform — it does not cover case law or statutes, but within its own domain it offers over 300 searchable fields, global forward/backward citation tracking grouped by invention family, and access to more than 73 million curated non-patent-literature publications for prior-art and novelty research.

Contract Analysis

Contract analysis is not part of this product; it is purpose-built for patent search, prior-art discovery, and freedom-to-operate (FTO) and validity research rather than reviewing commercial agreements.

Document Drafting

Derwent Patent Search is a search and retrieval platform, not a drafting tool — it does not generate patent applications or other legal documents.

Legal Translation

The platform does not offer a dedicated legal-translation feature, though its underlying patent index does draw on filings across 109 jurisdictions with expert-authored English-language summaries of non-English patent families.

Predictive Analytics

The platform includes citation-trend and invention-family analytics that help surface which prior art is most relevant or influential, but this is descriptive/relevance-ranking analytics rather than predictive modeling of litigation or prosecution outcomes.

Pricing

Clarivate does not publish pricing for Derwent Patent Search; as an enterprise IP-research platform, cost is quoted per organization based on scope and user count, and interested teams need to contact Clarivate directly.

User Reviews and Ratings

No independently verified G2 or Capterra review score could be confirmed for this specific product at the time of writing; Clarivate's own site cites a user quote describing AI Search as surfacing "the most relevant records... at the top of the list," but this is not a substitute for an independently tallied review score.

Verdict

Derwent Patent Search is a mature, deep-data patent-research platform backed by one of the industry's oldest curated patent indexes, making it a strong fit for IP teams that need thorough prior-art and FTO research at enterprise scale. It is not a general legal-research or contract tool, and buyers should treat its recent AI Search layer as a relevance-ranking aid on top of a very large, well-established dataset rather than a replacement for an experienced patent searcher's judgment.
