How this service works

Full US patent application file-wrapper detail by application number. Returns bibliographic data (title, inventors, applicants, dates, status, examiner, art unit, docket #, confirmation #) plus the file-wrapper event timeline (filing, IDS, Office Actions, allowance, abandonment, …), continuity chain (parent / continuation / divisional / national stage), recorded assignments (assignor → assignee with reel/frame + conveyance text), and foreign priority claims under 35 USC § 119. Application number is the 6-10 digit USPTO ID (e.g. 18566276).

Output

Returns a structured record containing: bibliographic data (title, inventors, applicants, filing/publication dates, status, examiner, art unit, docket number, confirmation number), a chronological file-wrapper event timeline (filing, IDS submissions, Office Actions, responses, allowance or abandonment events), the continuity chain (parent, continuation, divisional, national stage relationships), recorded assignments (assignor to assignee with reel/frame numbers and conveyance text), and foreign priority claims under 35 USC § 119.

Example use cases

When to prefer

Use this endpoint when you need comprehensive, structured USPTO file-wrapper data for a specific US patent application by its application number — especially when you need prosecution history events, assignment chain, continuity relationships, or foreign priority claims in a single call. Prefer over manual USPTO PAIR/Patent Center lookups when automating patent due diligence, portfolio analysis, or legal research workflows.

Invalid application number format — must be 6–10 digits
Application data not yet publicly available (pre-publication)
Payment failure via x402 protocol — insufficient USDC balance
Network timeout on USPTO data retrieval
