What it does
Patent Download is an agent skill from cat-xierluo/legal-skills. 专利 PDF 批量下载工具。当用户需要下载专利全文 PDF、查询专利信息、批量导出专利文件时使用。支持多平台（Google Patents 优先），自动处理申请号和公告号格式。
Its SKILL.md is about 950 tokens, which your agent loads only when the skill is triggered. The skill folder holds 23 other files, including scripts and reference files (for example `CHANGELOG.md`, `references/accounts-setup.md` and `references/examples.md`).
It sits in Legal & Compliance, covering Intellectual property. It works with Playwright and Python. The licence is MIT.
When your agent uses it
- Tasks that involve Intellectual property
Example prompts
- “/patent-download”
Requirements
- Python 3
- A Bash shell
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- cp config/.env.example config/.env
- 编辑 config/.env，填入你注册的账号（已 .gitignore，不入库）
- 账号自动从环境变量 / .env 加载（scripts/platforms/_creds.py，无需额外依赖）
- 安全自检：python scripts/platforms/_creds.py —— 检查 .env 是否被误提交到 git，并显示各平台账号是否就绪（不打印密码）
What it can do on your machine
Read from SKILL.md and the folder at commit db2c58c. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 9 files in scripts/ (Python and Shell, from the files we listed), which the agent can run.
Shell commands in SKILL.md call:
pythonpipplaywright
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use pip, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Patent Download loads about 951 tokens when it runs, and up to ~3.6k if it reads all its reference files. Until then it costs about 26 tokens; SKILL.md has 210 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.

patent-download - 专利下载工具
根据专利号从多个平台下载专利文本（PDF / 摘要 / 全文）。
何时用 / 何时不用
用：下载专利全文 PDF、批量导出专利文件、查询专利基本信息。 不用：专利侵权比对 / 权利要求分析 / 有效性核查等，请用专用分析工具。
推荐通道
Google Patents（API、免费免登录）为首选，度衍专利（浏览器）为备选。各平台实测状态、推荐度与接入方式见 references/platform-status.md。
专利号格式（关键）
用户给的往往是申请号（如 202421964517.8），Google Patents 用公告号（如 CN223081266U）索引。两者无数学对应关系，google_patents.py 会尝试自动匹配但不保证成功。
完整的申请号/公告号结构、种类代码（A/B/U/S）、发明 A vs B 区别、默认下载规则见 references/patent-number-formats.md。

| 通道 | 依赖 | 安装命令 |
|---|---|---|
| Google Patents 下载（推荐） | patent-downloader | pip install patent-downloader |

| PatentStar/epub API 等 | requests | pip install requests |
一条命令装全部：pip install -r scripts/requirements.txt。
所需权限与安全说明
本技能会执行本地脚本完成专利下载，涉及以下能力边界，请在使用前知悉：
运行时自动安装依赖（请留意）
scripts/patent-download.sh包装脚本在缺少依赖时会自动执行pip install与playwright install chromium：- 首个参数为
google时，若未装patent-downloader会自动pip install patent-downloader； - 其他参数走老版路径时，若未装
playwright会自动pip install -r requirements.txt并下载 Chromium 浏览器二进制。
- 首个参数为
- 该自动安装没有固定版本（unpinned），会从网络拉取最新包，存在供应链风险。请知悉：自动安装前建议人工审查
scripts/requirements.txt，或改为手动安装（pip install -r scripts/requirements.txt）。 - 直接调用
python cli.py <平台> <专利号>不会触发自动安装，缺依赖时只会打印清晰提示并退出。
网络访问
- 按用户指定的专利号向外部平台发起网络请求下载专利全文/PDF：Google Patents（API）、度衍、粤港澳、PSS、PatentStar、CNIPA epub 等。请求对象由用户输入的专利号决定，不会上传本地文档内容。
- 使用
requests/patent-downloader/playwright（浏览器自动化）等依赖完成下载。
凭证访问
- 各平台账号通过环境变量（
PATENT_<平台>_USERNAME/PATENT_<平台>_PASSWORD）或本地config/.env读取（见「凭证」章节）。凭证仅用于登录下载，不硬编码、不打印密码。 - 凭据等同账号密码，请勿截图、分享或提交到任何仓库。
浏览器自动化
- 部分平台（度衍/粤港澳/PSS）使用 Playwright 驱动 Chromium，支持
--headless无头模式。会在本机启动浏览器进程执行登录与下载操作。
文件访问
- 在用户指定输出目录（
-o，默认当前目录）写入下载的 PDF/文件。

When should I use Patent Download?
Patent Download fits situations like: tasks that involve Intellectual property.
How do I install Patent Download in Claude Code?
Run `npx skills add cat-xierluo/legal-skills --skill patent-download -a claude-code`. Or copy the skill folder (skills/patent-download in cat-xierluo/legal-skills) into .claude/skills/patent-download in your project. Claude Code loads it when a task matches its description.
How do I install Patent Download in Codex?
Run `npx skills add cat-xierluo/legal-skills --skill patent-download -a codex`. Or copy the skill folder (skills/patent-download in cat-xierluo/legal-skills) into .agents/skills/patent-download in your project. Codex loads it when a task matches its description.
Can I use Patent Download in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add cat-xierluo/legal-skills --skill patent-download -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/patent-download, .gemini/skills/patent-download, .github/skills/patent-download and .opencode/skills/patent-download in your project.
What does Patent Download need to run?
Going by SKILL.md and its folder, Patent Download needs Python and a shell for the scripts in its folder and the command-line tools its instructions call (python, pip and playwright). Our summary lists: Python 3; A Bash shell.
Does Patent Download access the network?
SKILL.md contains no URLs. Its commands use pip, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Is Patent Download safe to install?
Our automated static check of SKILL.md found notes only (mentions a .env file), nothing it rates as a warning. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
What licence does Patent Download use?
Patent Download is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Patent Download use?
About 951 tokens (SKILL.md is roughly 3.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 2.7k tokens, read only when the agent opens those files.
What are the alternatives to Patent Download?
Skills that share tags, products or a category with Patent Download: USPTO Patent and Trademark Data (davila7/claude-code-templates, 33k stars), Web Application Testing (anthropics/skills, 180k stars), Paper to Chinese Patent Drafter (Yuan1z0825/nature-skills, 47k stars) and Merge Dependabot PRs (onyx-dot-app/onyx, 32k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
