# Claims Drafting: The Core Patent Skill

> **Before each reviewer slot**, follow [Selectable Reviewers](../shared-references/reviewer-backends.md):
> 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`
