# Claims, abstract and CPC of a granted patent

`GET /v1/patents/{patent_number}/claims`

## Request

- Base URL: `https://api.patentdata.ai`
- URL: `https://api.patentdata.ai/v1/patents/{patent_number}/claims`
- Auth: one of:
  - API key in header `X-API-KEY`
  - HTTP bearer

Answers: what does this granted patent actually claim, what is it about, and how is it classified. Returns `claims` [{number, text, dependent_on}] (dependent_on lists the claims a dependent claim refers to; empty for independent claims; `canceled: true` marks claims canceled by amendment, `number_raw` flags a claim USPTO mis-numbered), `independent_claims`, `claim_count`, `canceled_claims`, `abstract`, `cpc` (CPC symbols as classified at issue, main first), `title`, `kind`, `application_number`, `date`. Text comes from USPTO's weekly full-text XML; a number outside the weeks we hold is a 404 whose `detail` states the covered dates — the status endpoints cover every application regardless. Costs 1 request.

## Path parameters

- `patent_number` string, required: US patent number without commas; design/plant/reissue prefixes allowed (D912345, PP12345, RE48123).
