How to Use the Lens.org Patent Database
Last revised:
April 19, 2026
The Lens (lens.org) is a free, comprehensive patent and scholarly search platform that links patents to the academic literature that cites them — and vice versa. This bidirectional linkage makes it uniquely powerful for understanding how an invention connects to the broader research landscape.
Getting Started
Go to lens.org and create a free account. Select "Patents" from the search options. Enter keywords, patent numbers, applicant names, or classification codes. The Lens searches over 140 million patent records from virtually every patent office worldwide.
Key Features
Patent-to-scholarly linkage. The Lens maps citations between patents and academic papers — showing which papers a patent cites and which papers cite the patent. This is invaluable for understanding the scientific foundation of an invention and identifying academic groups working in the same space.
Patent collections. Save groups of patents into collections for ongoing monitoring, portfolio analysis, or prior art documentation.
Analytical dashboards. Visualise filing trends, geographic distribution, technology classification distribution, and applicant concentration for any patent set.
Biological patent lens. For biotech inventors, the Lens maps patent claims to specific gene sequences, protein structures, and biological entities — linking IP to biological data in a way no other free tool provides.
When to Use The Lens vs Other Tools
Use The Lens when you need to connect patents to academic literature, when you want free analytical visualisations, or when you're doing biotech-specific patent research. Use Espacenet for classification-based searching and legal status. Use Google Patents for quick keyword searches and citation mapping. Use PATENTSCOPE for PCT-specific and cross-lingual searching.
