## What it does

The skill calls `POST /zhihuiya/bibliography` and returns patent metadata: title, original applicants and current assignees, inventors, agents and agency, examiners, priority claims, filing and publication references, IPC, CPC, UPC, LOC, FI and F-term classes, cited patents and non-patent literature, PCT filing and publishing data, plus an estimated expiry date. You query by `patentId` or `patentNumber`, up to 100 comma-separated values per request with no spaces. Pass both and `patentId` wins.

Under the hood it is a Python script, `scripts/zhihuiya_bibliography.py`, that takes JSON parameters. Every response lands in `<cwd>/linkfox/<YYYY-MM-DD>/<session>/data/`. Stdout gets the full JSON when the body is 8 KB or smaller, otherwise a summary with top-level fields and the first three samples; `--inline` forces the whole thing out. Reading the saved file with `jq` keeps your context clean.

You need an API key in `LINKFOX_AGENT_API_KEY` or `LINKFOXAGENT_API_KEY`. Without it, or on a 401, 402, or a low-balance message, the skill falls back to `references/onboarding.md`. Calls burn compute credits, so the script caches locally for 24 hours and will not repeat the same parameter set in one session. Worth knowing: on an empty result it does not silently try other keywords or page through numbers — it asks you first.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add linkfox-ai/linkfox-skills --skill linkfox-zhihuiya-bibliography -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/linkfox-zhihuiya-bibliography/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/linkfox-zhihuiya-bibliography/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add linkfox-ai/linkfox-skills --skill linkfox-zhihuiya-bibliography -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/linkfox-zhihuiya-bibliography/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add linkfox-ai/linkfox-skills --skill linkfox-zhihuiya-bibliography -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/linkfox-zhihuiya-bibliography/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install linkfox-ai/linkfox-skills linkfox-zhihuiya-bibliography
```

2. **Manually: put the files in place**
- File: `.github/skills/linkfox-zhihuiya-bibliography/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add linkfox-ai/linkfox-skills --skill linkfox-zhihuiya-bibliography -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/linkfox-ai/linkfox-skills --path skills/linkfox-zhihuiya-bibliography
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/linkfox-zhihuiya-bibliography/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add linkfox-ai/linkfox-skills --skill linkfox-zhihuiya-bibliography -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/linkfox-ai/linkfox-skills/tree/HEAD/skills/linkfox-zhihuiya-bibliography/SKILL.md

## When to use it
- list inventors and assignees for a publication number
- collect IPC and CPC classes across a patent set
- see which documents a patent cites
- check priority claims and publication dates
- get the abstract and patent type in one table

## Example prompts
- Show me the bibliography for US10123456B2
- Get bibliographic data for CN112345678A, EP3456789B1, and US20210012345A1
- Look up inventors and assignees for these 20 publication numbers

# Zhihuiya Patent Bibliography

This skill guides you on how to query patent bibliography (bibliographic) data from the Zhihuiya patent database, helping users retrieve detailed metadata for specific patents.

## Core Concepts

Patent bibliography data (also called bibliographic data) is the structured metadata associated with a patent document. It includes the patent title, applicants, inventors, classification codes, priority claims, cited references, abstracts, and more. This tool allows querying by **patent ID** or **publication number**, returning comprehensive bibliographic records for up to 100 patents per request.

**Patent types**: The `patentType` field indicates the type of patent document:
- `APPLICATION` -- Invention application (published but not yet granted)
- `PATENT` -- Granted invention patent
- `UTILITY` -- Utility model
- `DESIGN` -- Design patent

## Data Fields

| Field | API Name | Description |
|-------|----------|-------------|
| Patent ID | patentId | Internal patent identifier |
| Publication Number | pn | Publication/announcement number |
| Invention Title | inventionTitle | Patent title with language info |
| Abstracts | abstracts | Patent abstract text |
| Patent Type | patentType | APPLICATION, PATENT, UTILITY, or DESIGN |
| Applicants | applicants | Original applicant(s) |
| Assignees | assignees | Current patent holder(s) / assignee(s) |
| Inventors | inventors | Inventor(s) listed on the patent |
```
