Google Patents API endpoint

Patents Detail API

Returns a single patent's detail: title, abstract, inventors, assignees, dates, legal status, CPC/IPC classifications, claims, description, patent citations, cited-by patents, family members, and similar documents. `number` is a publication number such as `US10758101B2`, `EP1000000A1`, or `WO2020123456A1`. To search or browse by keyword, inventor, or assignee instead of a known publication number, use `/googlepatents/search`.

How this endpoint behaves

Query parameters:

number (required) — publication number, e.g. US10758101B2, EP1000000A1, WO2020123456A1.
lang (optional, default en) — language code for the translated page. Not a fixed enum: Google Patents serves whichever machine-translation languages exist for a given document, a set that varies per patent.

Response fields: publication_number, title, abstract, country_code, country_name, kind_code, application_number, priority_date, filing_date, publication_date, expiration_date, legal_status, inventors[], current_assignees[], original_assignees[], prior_art_keywords[], classifications[] (code, description, is_cpc), claims_count, claims[], description[] (paragraphs), citations[] and cited_by[] (publication_number, priority_date, publication_date, assignee, title), family_members[] (publication_number, publication_date), similar_documents[] (publication_number, publication_date, title), pdf_url, source_url, fetched_at.

An unknown or invalid publication number returns 404.
