Claims Drafting: The Core Patent Skill

Before each reviewer slot, follow Selectable Reviewers: resolve invocation → .aris/reviewer.json → Claude Code default (Codex MCP) with reviewer_route.py through the canonical helper resolver, preserving this slot's tier, fresh contexts, source/image inputs and deterministic gates. Codex examples/pins below apply only to backend=codex; other routes use their own first-call/reply contract. Save the route and actual returned identity; unavailable selections are REVIEW_UNAVAILABLE. Classify acceptance from actual families/completion/scope. Forward invocation reviewer/model/effort overrides to reviewer-bearing children. Generation workers are unchanged.

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-6-astra, External examiner for claim quality review
• MAX_CLAIM_REVISION_ROUNDS = 3, Maximum revision iterations
• CLAIM_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

1. patent/INVENTION_DISCLOSURE.md, structured invention with core/supporting/optional features
2. patent/PRIOR_ART_REPORT.md, prior art to avoid
3. patent/NOVELTY_ASSESSMENT.md, novelty analysis with suggested amendments
4. Target jurisdiction from invention disclosure or $ARGUMENTS
