Which companies are granting a cluster of patents?
Which companies are granting a cluster of patents? Bulk feed over USPTO / PatentsView granted-patent assignees, ordered by grant count in the loaded window — an assignee with a cluster of grants is an R&D/growth signal. Cursor-paginated up to 1000/page, filterable by state, minimum grants, CPC subclass, first-time-assignee only, or since. Rows carry the assignee, grant count, CPC tech areas, grant window, inventor count, and a first_time_assignee flag. CC BY 4.0 attribution (in _meta.notice).
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
