Claims Drafting: The Core Patent Skill
Draft patent claims based on: $ARGUMENTS
This is the most critical skill in the patent pipeline. Claims define the legal scope of protection -- everything else (specification, figures, abstract) exists to support and enable the claims.
Constants
REVIEWER_MODEL = gpt-5.5 — External examiner for claim quality reviewMAX_CLAIM_REVISION_ROUNDS = 3 — Maximum revision iterationsCLAIM_STYLE = "auto" — US (Jepson or open), EP (two-part mandatory), CN (two-part), auto (detect from jurisdiction)MIN_INDEPENDENT_CLAIMS = 2 — Typically method + system. For utility model (实用新型): apparatus/device only, NO method claims.MAX_TOTAL_CLAIMS = 20 — Practical limit (USPTO includes 20 in base fee)PATENT_TYPE = "invention" — invention (发明专利) or utility_model (实用新型, apparatus claims only)
Inputs

Shared References
Load ../shared-references/patent-writing-principles.md for claim drafting principles, antecedent basis rules, and common pitfalls.
Load ../shared-references/patent-format-cn.md for CN claim format (其特征在于).
Load ../shared-references/patent-format-us.md for US claim format (comprising, means-plus-function).
Load ../shared-references/patent-format-ep.md for EP two-part form (characterised in that).
Workflow
Step 1: Determine Claim Style and Patent Type
Based on patent type and jurisdiction:
If PATENT_TYPE = utility_model (实用新型):
- CN jurisdiction ONLY
- Apparatus/device claims ONLY — no method, no product-by-process
MIN_INDEPENDENT_CLAIMS = 1 (single apparatus claim is sufficient)- Claim format: "1. 一种[主题]，其特征在于，包括：[组件描述]。"
