Patent Status API

The status of every US patent application — pending, rejected, allowed, abandoned, granted — plus office actions, ownership, PTAB challenges, maintenance fees and disambiguated entities, built from USPTO bulk data and refreshed daily. Per request. No seats, redistribution allowed, no restrictions on AI use.
