who it's for

Who patent-disclosure-skill is for#

Chinese R&D engineers filing their first patent

Point the skill at your project directory, name the patent type, and it extracts candidate patent points, conducts a CNIPA prior art search, and drafts the disclosure document with required diagrams. The engineer reviews and iterates; each round creates a new versioned file with a revision log.

Skip if:

Skip if your target jurisdiction is outside China. The prior art search and disclosure templates are built for CNIPA, not USPTO or EPO filings. International filers need a different workflow for those jurisdictions.

IP teams accelerating engineer disclosure intake

Engineers generate a structured disclosure draft from their own project materials before submitting to the IP team. The team receives a document with prior art citations, diagrams, and patent points already identified, reducing the back-and-forth needed to reach a complete submission.

Skip if:

Skip if your engineering teams already produce structured disclosures with diagrams and prior art searches independently. This skill adds the most value at the initial disclosure drafting stage, before attorney review.

Patent practitioners decoding existing Chinese patents

Feed a patent number or PDF into reader mode and receive a plain-language summary: claims tree, terminology glossary, feature-to-description mapping, and a Canvas knowledge map in Obsidian. Multiple patents accumulate into a private knowledge base with cross-links and tag-based search over case history.

Skip if:

Skip if you need the full knowledge graph experience but cannot configure an Obsidian vault. The plain-output fallback mode works, but the cross-patent linking and relationship graph features require the vault.

Teams managing recurring CNIPA office action responses

Past cases are tagged by defect type and CNIPA law article, then stored in Obsidian. When a new examination notice arrives, the skill filters relevant cases by tag and generates a draft response. Teams with a growing case library can add optional vector search for semantic case retrieval.

Skip if:

Skip if you have only a handful of past cases. The case library delivers the most value with a substantive history of office actions and responses to draw semantic matches from.

the problem

The problem it solves#

Engineers who do the core technical work at Chinese technology companies rarely appear on the resulting patents. The barrier is not technical knowledge but procedural: extracting patentable claims from a codebase or design document, conducting a prior art search against the Chinese national patent database (CNIPA), and producing a disclosure document in the correct format for each patent type takes a workflow that most engineers have never been trained to do.

The tools that exist for this workflow are built for patent professionals, not engineers. Commercial patent drafting platforms require describing the invention in abstract terms, not pointing at a project directory. The result is disclosures that miss patentable angles, or engineers who simply do not file and lose credit for what they built.

how patent-disclosure-skill solves it

How it solves it#

Patent point mining from project materials

Scans your project directory in priority order: documentation first, then source code. Converts .docx and .pptx files to Markdown before scanning so structured documents are fully readable. From those materials it identifies candidate patentable claims and presents them for review before drafting begins.

Three patent types: invention, utility model, and design

Drafts disclosures for all three CNIPA patent types with separate templates per type. Invention patents use Mermaid flowcharts for the required block diagrams. Utility model and design patents generate structural line-art or appearance line-art, including part numbering for utility models and multiple view angles for design patents.

CNIPA prior art search via official database

Searches the China National Intellectual Property Administration public announcement database (epub.cnipa.gov.cn) first, using a dedicated Playwright-based crawler aligned to the patent type. Falls back to web search if the CNIPA database returns no results. Prior art citations are written into chapter one of the disclosure.

Timestamped versioning with revision history

Every output file is named with the case name and a timestamp, so each iteration produces a new file rather than overwriting the previous version. Corrections and supplemental material merges create new timestamped copies alongside a revision conversation log, giving a full audit trail across multiple drafting rounds.

Patent plain-language reader with Obsidian knowledge graph

Converts patent PDFs or public numbers into plain-language notes covering the claims tree, terminology glossary, and feature-to-description mapping. Notes are saved to an Obsidian vault with Canvas knowledge maps, cross-patent relationship links, and configurable CSS for callout coloring. Multiple patents accumulate into a searchable private knowledge base.

Examination response drafting with case RAG

Stores historical office actions and responses in Obsidian with CNIPA law article tags. When a new examination notice arrives, it filters past cases by defect type and generates a draft response. Supports optional vector embedding for semantic case retrieval; the tag-filter path works without a vector model.

Strengths and trade-offs#

Strengths

MIT licensed, free to self-hostThe tool carries an MIT license with no seat fees, API billing, or subscription. All processing runs locally on your own infrastructure. Compared to Solve Intelligence or Questel Patent Drafting, which price by seat or query volume, self-hosting this skill costs only the server time you would use anyway.
Works from actual project artifacts, not retrospective descriptionsInput is your project directory: source code, documentation, CAD files. You do not need to describe the invention from memory. The skill reads the same materials the invention was built from, which reduces the risk of missing patentable angles that only appear in the implementation details.
Built for the CNIPA system from the startPrior art search targets the CNIPA public announcement database by default, with patent type-aligned queries. Disclosure templates match CNIPA formatting requirements for each of the three patent types. This is not a generic drafting tool adapted for China: it was designed for the Chinese filing system specifically.
5,848 stars with active development and low open-issue countThe repository has 5,848 stars and 710 forks with only 8 open issues, reflecting active maintenance at a fast response cycle relative to community size. The project reached that adoption level within its first five months, indicating strong demand for this workflow in the Chinese developer community.

Trade-offs

-China patent system onlyPrior art search and disclosure templates are built for CNIPA filings: invention, utility model, and design patents under Chinese law. USPTO, EPO, PCT, and other jurisdictions are not supported. Teams filing internationally need a separate tool or workflow for non-CNIPA filings.
-Requires an AI agent host environmentThis is an AgentSkills-format skill, not a standalone application. It runs inside a compatible AI agent runtime. Setting up the skill requires configuring that host environment in addition to the Python 3.9+ and Playwright dependencies documented in the project's INSTALL.md.
-Full patent reader experience requires ObsidianThe knowledge graph, Canvas maps, cross-patent linking, and callout CSS configuration depend on an Obsidian vault being configured. Without Obsidian, the patent reader falls back to a plain output directory, dropping the relationship-graph and multi-patent accumulation features.

frequently asked

FAQ#

Does patent-disclosure-skill support patents outside of China?

No. The skill is built specifically for the Chinese patent system. The prior art search targets the CNIPA public database, and the disclosure templates are formatted for CNIPA invention, utility model, and design patent filings. USPTO, EPO, and PCT workflows are not supported.

Is Obsidian required to use patent-disclosure-skill?

Obsidian is required only for the patent reader mode's knowledge graph features. The disclosure drafting workflow (the core use case) does not depend on Obsidian: outputs land in a timestamped files directory. Without Obsidian, the reader mode still produces notes but drops the Canvas maps, cross-patent links, and relationship graph.

What patent types does the skill support?

The skill supports all three CNIPA patent types: invention patents, utility model patents, and design patents. Each type uses a separate disclosure template with type-specific diagram generation. Invention patents are the default if no type is specified; the skill prompts to switch if the submitted materials look structural or appearance-focused.

How does the prior art search work?

The skill searches the CNIPA public announcement database (epub.cnipa.gov.cn) by default, using a Playwright-based crawler aligned to the patent type. If that search returns no usable results or encounters an error, it falls back to a general web search. Prior art citations are written into the first chapter of the disclosure document.

Is patent-disclosure-skill free to use?

Yes. The repository is MIT licensed, so you can run it on your own infrastructure at no cost. There is no subscription, per-query fee, or managed API to pay for. The only costs are the AI agent host environment you run it inside and the compute for the Python dependencies.
