Patent Family & Citation Graph
For a batch of patent publication numbers, return the citation graph, the patent family across offices, legal status and expiration, and what changed since the last check (status change, reassignment, new citations, new family members). Sourced from the robots.txt-allowed Google Patents pages.
For a batch of patent publication numbers (e.g. US10000000B2,
EP3268771B1, WO2020123456A1), this Actor returns:
- Bibliography: title, current assignee organisation, filing date, publication date, grant date (when the document is actually a grant -- correctly distinguished across the pre-2001/post-2001 USPTO kind-code boundary), expiration date, jurisdiction, and the leaf CPC classification codes.
- The citation graph: which patents this one cites (
citations_backward) and which patents cite this one (citations_forward). - The patent family: the same invention's equivalents filed at other
patent offices (
family_members) -- a US grant's Japanese, European, Israeli or other counterparts. - Current legal status: Active, Expired, Granted, and so on, as recorded by Google Patents' own IFI-derived status.
- What changed since the last check. This Actor keeps a per-patent
snapshot across runs. Check the same patent number again next week, next
month, next quarter, and you get
previously_checked: trueplus, when anything moved,changed_since_last_check: trueand achangeslist naming exactly what: a status change, a reassignment (a new owner of record), a new patent-family member, new forward citations, or a new legal event (reported as a date, a short category such as "Assignment", and an event code -- never free text, which is where a person's name can appear in the source's own records).
What this Actor never returns
No inventor name. No free-text legal-event detail (the kind of field that can contain an individual's name inside boilerplate like an assignment record). This Actor reports on patents and the organisations that own them, not on the people named as inventors.
Input
One patent publication number per line (or comma-separated). An
application number (e.g. US14/643,719) is a different identifier and
is not accepted -- only a publication number resolves to a
patents.google.com/patent/{number} page.
Pricing
Charged per patent number that resolves to a real, verified patent record. A number that does not exist (never issued, or mistyped) is not charged.
Source and affiliation
Data is read from individual pages on patents.google.com, respecting that
site's robots.txt (only the explicitly allowed /patent/{id} path is ever
requested). This Actor is not affiliated with, endorsed by, or sponsored
by Google LLC. "Google Patents" is a trademark of Google LLC.
