The Lens
A combined search and analytics platform covering scholarly works alongside patents, with more than 270 million records. The web interface lets you search and cross-reference research and patent literature in one place. Its API is approval-gated and largely paid, so the practical route is the website — useful when a question spans both academic publications and patents.
No programmatic check — opens the archive’s own search.
