Two main modules
- Bulk Downloader automates downloading of public bulk patent data
- Patent Document provides the ability to iterate and read patents directly from the large bulk download files, supports reading patent documents from 1976 to current, which includes Greenbook, SGML, PAP, and all Redbook XML formats, into a normalized Patent Object Model.
- Download Bulk Patent Grants and Applications, as well as additional resources
- View individual Patent Documents directly from the large bulk files
- Read Patent Documents directly from the large bulk files, supports reading patent documents from 1976 to current (formats: Greenbook, SGML, PAP, Redbook XML) into a normalized Patent Object Model
- Extract Patent Documents from bulk files
- Normalize and transform Patent data before loading into a data resource
- Patent Claim Tree to facilitate analysis
- Update Classifications from Master CPC File (current CPC classification for patents starting from patent number 1)
- Include classification definitions from CPC Scheme
- Build a corpus using Corpus Builder, which automates building a corpus by downloading and extracting patents/applications matching specified classifications, one bulk file at a time for a date range.
