Patent Pipeline: From Invention to Filing

Draft a complete patent application based on: **$ARGUMENTS**

Overview

This skill orchestrates the full patent drafting lifecycle -- from prior art search through jurisdiction-formatted filing documents. It chains sub-skills into a patent-specific pipeline:

/prior-art-search → /patent-novelty-check → /invention-structuring → /claims-drafting → /specification-writing → /patent-review → /jurisdiction-format
     (search)           (verify)              (structure)             (claims)            (description)          (examiner)         (compile)
                                                                                              ├── /figure-description
                                                                                              └── /embodiment-description

**This is a parallel branch, not part of the linear research pipeline.** After `/idea-discovery` produces validated ideas, the user can either:

• Go to `/experiment-bridge` → `/auto-review-loop` → `/paper-writing` (publish track)
• Go to `/grant-proposal` (funding track)
• Go to `/patent-pipeline` (patent track) **<-- this skill**

                    ┌→ /experiment-bridge → /auto-review-loop → /paper-writing  (publish track)
/idea-discovery ────┤
                    ├→ /grant-proposal → [get funded] → ...  (funding track)
                    └→ /patent-pipeline → [file patent]       (patent track)

Patents are about **protecting inventions** (legal scope), not publishing results (academic contribution). This skill handles the unique requirements of patent drafting: prior art analysis, claims hierarchy design, specification writing with enablement support, embodiment descriptions, and jurisdiction-specific formatting.

Constants

• **JURISDICTION = `CN`** — Target patent jurisdiction. Options: `CN` (CNIPA), `US` (USPTO), `EP` (EPO), `ALL` (generate all three). Override via argument (e.g., `/patent-pipeline "invention — US"`).
• **PATENT_TYPE = `invention`** — `invention` (发明专利, 20 year protection) or `utility_model` (实用新型, CN only, 10 year protection, apparatus claims only). Override via argument.
• **REVIEWER_MODEL = `gpt-6-astra`** — Model used via Codex MCP for examiner-style review.
• **MAX_REVIEW_ROUNDS = 2** — Maximum review-revision cycles.
• **AUTO_PROCEED = false** — At each checkpoint, **always wait for explicit user confirmation**. Patent applications require inventor judgment at every stage. Set `true` only if user explicitly requests autonomous mode.
• **LANGUAGE = `auto`** — Output language. Auto-detected from jurisdiction: CN->Chinese, US->English, EP->English. Override explicitly if needed.
• **OUTPUT_DIR = `patent/`** — Directory for generated patent files.
• **OUTPUT_FORMAT = `markdown`** — Draft format. `markdown` for review, `docx` for filing-ready.

> Override defaults via arguments: `/patent-pipeline "invention — US, utility model"` or `/patent-pipeline "invention — ALL, language: Chinese"`.

Patent Type Specifications

Invention Patent (发明专利)

| Field | Detail | |-------|--------| | **Protection** | 20 years from filing date | | **Subject matter** | Methods, systems, products, compositions, processes | | **Examination** | Substantive examination required | | **Inventive step** | High (must involve an inventive step / 创造性) | | **Timeline** | 2-4 years to grant (CN); 2-3 years (US); 3-5 years (EP) | | **Claims** | Method + system + product claims allowed |

Utility Model (实用新型) — CN Only

| Field | Detail | |-------|--------| | **Protection** | 10 years from filing date | | **Subject matter** | Product shape, structure, or combination thereof only | | **Examination** | Formal examination only (no substantive examination) | | **Inventive step** | Lower than invention patent | | **Timeline** | 6-8 months to grant | | **Claims** | Apparatus/device claims only. NO method claims. | | **Restriction** | CN jurisdiction only |

State Persistence (Compact Recovery)

Patent drafting is a long task that may trigger context compaction. Persist state to `patent/PATENT_STATE.json` after each phase:

{
  "phase": 3,
  "jurisdiction": "CN",
  "patent_type": "invention",
  "language": "Chinese",
  "codex_thread_id": "019cfcf4-...",
  "invention_title": "...",
  "claims_count": 15,
  "status": "in_progress",
  "timestamp": "2026-04-10T15:00:00"
}

**Write this file at the end of every phase.** On invocation, check for this file:

• If absent or `status: "completed"` -> fresh start
• If `status: "in_progress"` and within 24h -> **resume** from saved phase (read output files to restore context)
• If older than 24h -> fresh start (stale state)

On completion, set `"status": "c
