Corporate Patents (USPTO)

Returns US patent applications keyed on the corporate applicant — the IP-holding entity that owns the filing — sourced from the USPTO Open Data Portal (ODP). Each record carries the bibliographic metadata for one application (title, applicants, inventors, filing dates, prosecution status); follow source_url to the USPTO Patent Center for the full file wrapper.
