In their own words
The Lens
The Lens connects scholarly literature and patent records for discovery, analysis, decision-making, and partnering. Patent search offers Boolean, structured, biological, and classification queries, alongside filters and sorting. The Lens says its scholarly collection contains more than 200 million records and links scholarly works to patents through citations. PatSeq tools search, analyze, and share biological sequences disclosed in patents. Search results can be visualized in charts and dashboards, which users may save and share. Registered users can save collections and queries, add notes, and receive notifications when new indexed results match them. Lens Profiles combine author and inventor records and support ORCID linking and synchronization. Anonymous browsing is free, as is a non-commercial academic workspace for users with an academic institutional email. Individual commercial users need commercial-use permissions through a subscription or institution. The Individual Professional Workspace costs $1,000 a year. APIs support programmatic search and retrieval, subject to approved access and a token.
