A real patent from the USPTO weekly release runs through the extraction pipeline: CPC/IPC classification, assignee resolution against an entity registry, inventor extraction, and claim isolation with the independent claim identified separately.
- 1The source shows a real USPTO patent in XML format
- 2Press "extract" to run the worker pipeline
- 3CPC and IPC codes extracted and expanded against the classification hierarchy
- 4Assignee name resolved: "Acme Corp" → normalized_name, CIK, LEI, span
- 5Each inventor extracted with name, city/country, and span
- 6Claims section isolated — claim 1 (independent anchor) identified separately
- 7ML-based tech-area classification added alongside CPC
- 8The source XML re-renders with margin brackets at each emitted span
Why it matters
Patents are the rare public document where the claims matter more than the prose, and the assignee matters more than the inventor — both buried in XML that most tools flatten into plain text. A worker pipeline preserves structure and enables real downstream use.
