Individual skill

patent-mining

Retrieves and interprets patent data with the conventions that make counts and claims defensible, covering Google Patents, Lens, EPO Open Patent Services, USPTO data through PatentsView and the Open Data Portal, and WIPO PATENTSCOPE, together with kind codes, DOCDB and INPADOC families, priority versus filing versus publication dates, CPC and IPC classification, claim structure, assignee normalization and the limits of chemistry in patents, and records every query with the date it was run. Use for prior-art checks, freedom-to-operate scoping, technology landscapes, assignee or inventor analyses and patent-derived chemistry; use literature-review for scholarly sources and research-lookup for one quick fact.

# Patent mining

Patent data is jurisdiction-specific, dated several ways, and duplicated across family
members. A count means nothing without the source, the date field, the family definition
and the exact query on the day it ran. Treat every number as "N documents matching Q in
source S on date D", and write it that way.

## Data sources

1. **Google Patents** (patents.google.com): full text across many offices with machine
   translation, CPC browsing, similar-document search and CSV export of result lists. No
   official API; for bulk SQL use the Google Patents Public Datasets on BigQuery
   (`patents-public-data.patents.publications`).
2. **Lens** (lens.org): patents linked to scholarly works, families and citations, free
