Draft patent claims for an invention. Use when user says "撰写权利要求", "draft claims", "写权利要求书", "claim drafting", or wants to create patent claims. The core skill of the patent pipeline.

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 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 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]。" Based on target jurisdiction: Jurisdiction Claim Style Characterising Phrase Preamble Format CN Two part (两部式) 其特征在于一种...的方法/装置，包括： US Open (preferred) comprising A method for..., comprising: EP Two part (mandatory) characterised in that A method for..., comprising [known], characterised in that [inventive] ALL Draft CN + US + EP All of the above All of the above Step 2: Draft Independent Claims CRITICAL — Claims numbering (CN format): Claims must be numbered 1, 2, 3, ... continuously without gaps Independent and dependent claims are INTERMIXED in final numbering Do NOT group independent claims separately from dependent claims Example correct: Claim 1 (independent, product), Claim 2 (depends on 1), Claim 3 (depends on 1), Claim 4 (independent, method), Claim 5 (depends on 4)... Example WRONG: Claim 1 (independent), Claim 5 (independent), Claim 8 (independent), then Claim 2, 3, 4, 6, 7, 9, 10 as dependents CRITICAL — No empirical content in claims: Claims describe ONLY structural features or method steps Do NOT include signal characteristics, detection principles, measurement results WRONG: "产生负脉冲信号" / "谐振频率下降" — these are results, not features RIGHT: "所述开口谐振环的开口处形成用于检测通过流体中颗粒物的间隙传感区域" For each claim category identified in INVENTION DISCLOSURE.md: Method Claim (broadest) : 1. Start with preamble identifying the category and purpose 2. List the core inventive features (from the "Core Inventive Concept" section) 3. Include enough known features for context (but not more than necessary) 4. Use open transition ("comprising" / "包括") 5. Each element should be separated by semicolons or on separate lines 6. Apply jurisdiction specific format: CN: 前序部分 + "其特征在于" + 特征部分 US: Preamble + "comprising:" + elements EP: Preamble + known features + "characterised in that" + inventive features System/Apparatus Claim : 1. Mirror the method claim in structural form 2. Each method step becomes a "module configured to..." or "component for..." 3. Same hierarchy of known vs. inventive features Quality checks for each independent claim : [ ] Single sentence (US/EP) or properly structured (CN) [ ] Antecedent basis: "a" first, "the" thereafter for each element [ ] No relative terms without definition [ ] No result to be achieved limitations [ ] Transitional phrase is appropriate (open preferred) [ ] Preamble does not import unnecessary limitations [ ] Each element is necessary for patentability [ ] Claim scope is broadest defensible over prior art Step 3: Draft Dependent Claims For each independent claim, draft 5 10 dependent claims that: 1. Narrow the core inventive features : Specific implementations, parameters, ranges 2. Cover preferred embodiments : Features from the specification's detailed description 3. Provide fallback positions : If the independent claim is rejected, these narrower claims may survive 4. Cover alternatives : Different ways to achieve the same inventive result Dependent claim format : CN: "根据权利要求X所述的[主题]，其特征在于，所述[特征]具体为..." US: "The [method/system] of claim X, wherein the [element] comprises [limitation]." EP: "The [method/system] according to claim X, characterised in that [limitation]." Rules for dependent claims : Each must add at least one meaningful limitation Must reference a prior claim by number Must not merely repeat the parent claim Should not be cumulative (each claim should be independently useful as a fallback) Multiple dependent claims (US: only "or" references, not "and") Step 4: Claim to Specification Mapping Create a preliminary mapping to verify enablement: Claim Element Must be described in specification Reference numeral [element 1] Yes/No [numeral] [element 2] Yes/No [numeral] If any element lacks specification support, add it to the specification requirements. Step 5: Cross Model Examiner Review Call REVIEWER MODEL via mcp codex codex with xhigh reasoning: Step 6: Revision Loop If the examiner review identifies issues: 1. Address all CRITICAL issues (anticipation, obviousness, indefiniteness) 2. Address MAJOR issues (scope too narrow, missing support, weak fallbacks) 3. Consider MINOR issues (antecedent basis, formatting) 4. Re submit to examiner for round 2 (use mcp codex codex with threadId) 5. Repeat up to MAX CLAIM REVISION ROUNDS times Step 7: Output Write patent/CLAIMS.md : Key Rules Claims are the single most important part of the patent. Everything else supports them. Draft independent claims first, then dependent claims. Independent claims must be broadest defensible scope over prior art not broader, not narrower. Each dependent claim should be independently useful as a fallback position. Antecedent basis is mandatory: "a processor" first, "the processor" thereafter. Use "comprising" (open) unless there is a specific reason for "consisting of" (closed). Never include result to be achieved language in claims ("configured to achieve high accuracy"). Never fabricate claim language every element must come from the actual invention. If drafting for ALL jurisdictions, produce separate claim sets for CN, US, and EP. If mcp codex codex is not available, skip cross model examiner review and note it in the output.
