Common questions
Common questions about Lens.org vs Scopus
Is Lens.org really free?
+
Yes for core search, analysis, and export functionality up to a defined record-export limit. Lens.org's stated pricing approach is sustainability-based rather than profit-driven; paid tiers exist for API access and larger-scale data services, but a subscription is not required to search or analyze scholarly and patent records.
Does Lens.org replace Scopus for citation metrics?
+
Not for institutionally mandated Scopus-derived metrics. If your institution or funder specifically requires CiteScore, SJR, or SciVal-based reporting, those are Scopus-data products. Lens.org is a strong complement — particularly for patent-linked analysis — but it is not a drop-in substitute where a policy names Scopus specifically.
Does Scopus index patents?
+
No. Scopus covers scholarly journals, book series, and conference proceedings only. Patent search and patent-to-literature linkage is Lens.org's distinctive strength.
Who runs Lens.org?
+
Lens.org is operated by The Lens Limited, an independent non-profit. It originated from Cambia, the Australian non-profit research group that built the original Patent Lens patent-search tool in 2001.
