Specification Writing: Section-by-Section Patent Description

Write the patent specification based on: $ARGUMENTS

Adapted from /paper-write for patent specifications. The specification supports the claims -- it is not a paper.

Constants

• REVIEWER_MODEL = gpt-5.5 — External reviewer for specification quality
• JURISDICTION = "auto" — Inherit from pipeline or detect from args; CN, US, EP, ALL
• OUTPUT_FORMAT = "markdown" — Markdown drafts; converted to filing format by /jurisdiction-format
• OUTPUT_DIR = "patent/" — Base output directory
• LANGUAGE = "auto" — Auto from jurisdiction: CN->Chinese, US/EP->English

Inputs

1. patent/CLAIMS.md — the drafted claims (primary source)
2. patent/INVENTION_DISCLOSURE.md — invention decomposition
3. patent/PRIOR_ART_REPORT.md — for background section
4. User-provided figures (if any)

Shared References

Load ../shared-references/patent-writing-principles.md for specification writing rules, language guidelines, and reference numeral conventions. Load ../shared-references/patent-format-cn.md or patent-format-us.md or patent-format-ep.md based on jurisdiction.

Workflow

Step 1: Initialize Specification Structure

Create the output directory and section files:

patent/specification/
├── title.md
├── technical_field.md
├── background.md
├── summary.md
├── drawings_description.md
├── detailed_description.md
└── abstract.md

Step 2: Write Title (发明名称)

• Must match the broadest claim scope
• No trademarks, no "improved" or "new" or "novel"
• CN format: "一种[领域]的[技术主题]" or "[领域]的[技术主题]装置"
• US/EP format: "[Technical topic] for [purpose]" or "[Technical topic] and method thereof"
• Keep concise (CN: typically under 25 characters; US: under 500 characters)

Step 3: Write Technical Field (技术领域)

1-2 paragraphs identifying the technical domain:

• "The present invention relates to [broad field], and more particularly to [specific area]."
• CN: "本发明涉及[技术领域]，具体涉及[具体领域]。"
