What it does

Linkfox Google Patent Search is an agent skill from linkfox-ai/linkfox-skills. 通过 Google Patents 公开专利数据库检索全球专利,支持关键词、发明人、受让人、国家、日期、专利状态等多维筛选,返回专利公开号、标题、发明人、申请/公开/授权日期、受让人、CPC 分类、PDF 链接等核心著录数据。当用户提到谷歌专利、Google Patents、专利检索、专利搜索、查专利、专利防侵权、FTO 排查、prior art search、专利侵权排查时触发此技能。即使用户未明确提及"Google Patents",只要用户希望通过关键词或著录条件检索专利文献,也应触发此技能。

Its SKILL.md is about 2.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts and reference files (for example `references/api.md`, `references/onboarding.md` and `scripts/google_patent_search.py`).

It sits in Legal & Compliance, covering Intellectual property. The licence is MIT.

When your agent uses it

  • Tasks that involve Intellectual property

Example prompts

  • “Google Patents”
  • “/linkfox-google-patent-search”

Requirements

  • Python 3
  • A credential in LINKFOX_AGENT_API_KEY
  • A credential in LINKFOXAGENT_API_KEY

Workflow steps

8 steps, taken from the first numbered list in SKILL.md.

  1. Present results as a table: show publicationNumber, title, inventor, assignee, publicationDate/grantDate per item.
  2. Show totals: always state the total hit count from searchInformation/pagination and the current page range.
  3. Date formatting: render filingDate/publicationDate/grantDate/priorityDate as readable dates.
  4. Links: surface patentLink and pdf so the user can open the patent directly.
  5. Scholar results: when scholar=true, visually distinguish Scholar articles from patents.
  6. Large result sets: present a summary table first, note the total, and offer to expand specific patents.
  7. Expand via sibling skills: to get full bibliographic/legal/family detail for a found patent, direct the user to…
  8. No fabrication: only display fields actually present in the response; never invent titles, dates, or assignees not returned.

What it can do on your machine

Read from SKILL.md and the folder at commit 38fef04. 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 2 files in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • skill.linkfox.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • LINKFOX_AGENT_API_KEY
    • LINKFOXAGENT_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Linkfox Google Patent Search loads about 2.5k tokens when it runs, and up to ~5k if it reads all its reference files. Until then it costs about 70 tokens; SKILL.md has 1,020 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~70
When it runs · the whole SKILL.md, loaded when a task matches
~2.5k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~5k

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 passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

通过 Google Patents 公开专利数据库检索全球专利,支持关键词、发明人、受让人、国家、日期、专利状态等多维筛选,返回专利公开号、标题、发明人、申请/公开/授权日期、受让人、CPC 分类、PDF 链接等核心著录数据。当用户提到谷歌专利、Google Patents、专利检索、专利搜索、查专利、专利防侵权、FTO 排查、prior art search、专利侵权排查时触发此技能。即使用户未明确提及"Google Patents",只要用户希望通过关键词或著录条件检索专利文献,也应触发此技能。

This skill searches the public Google Patents database, returning matching patents with publication numbers, titles, inventors, assignees, dates, CPC classifications, and PDF links. Useful for cross-border sellers doing freedom-to-operate (FTO) checks, prior-art searches, and patent-infringement risk screening before listing a product.

Core Concepts

Google Patents Search runs a query (q) against the public Google Patents corpus. The query supports Google Patents' native advanced syntax (e.g. owner:"company", inventor:"name", date ranges). Results are returned as a ranked list of patents (and optionally Google Scholar articles).

This skill returns a list of patents with bibliographic fields. To retrieve detailed bibliographic data, full text, legal status, family, or images for a specific patent found here, feed the returned patentId/publicationNumber into the corresponding linkfox-zhihuiya-bibliography / linkfox-zhihuiya-legal-status / linkfox-zhihuiya-patent-family skills.

Data Fields

调用方式

  • API 端点:POST /googlePatent/search(完整参数/响应/错误码见 references/api.md)
  • Python 脚本:python scripts/google_patent_search.py '<JSON 参数>' [--inline]
  • 成本约束:本工具会消耗算力;同一会话同一参数组合默认只调用一次,脚本带 24h 本地缓存。失败/空结果不得自动换关键词、翻页或改邮编连续试探;需要继续检索或翻页时先向用户说明会产生额外消耗。

输出策略(脚本默认行为):

  • 始终将完整响应写入 <cwd>/linkfox/<YYYY-MM-DD>/<session>/data/linkfox-google-patent-search-<timestamp>.json(<cwd> 为脚本执行时的工作目录,在 Claude Code 里即当前项目目录;<session> 取自环境变量 SESSION_ID,按用户任务自动聚合;禁止写入 /tmp,当前目录不可写则报错)
  • 响应体 ≤ 8 KB:落盘后把完整 JSON 打印到 stdout
  • 响应体 > 8 KB:落盘后 stdout 只输出摘要(顶层字段、常见计数如 total/costToken、最大列表字段的长度 + 前 3 条样本)
  • 加 --inline 强制全量打印到 stdout(同样落盘)

读数据建议:先看摘要判断是否足够;需要具体字段时优先用 jq或ConvertFrom-Json 从保存的 json 文件按需抽取,避免整份 JSON 进入上下文。

解决认证和算力问题

发生以下异常情况时,采用 references/onboarding.md 引导解决问题:

异常情况
  • 未配置API Key:环境变量未配置 LINKFOX_AGENT_API_KEY,也未配置 LINKFOXAGENT_API_KEY。
  • 响应401或402状态码
  • 响应提示算力或权限不足:消息含"算力余额不足/计费不足/余额不足/quota exceeded/insufficient balance/No permission/API package quota/套餐到期/需充值/请充值",或类似含义的内容。

before:publication:20250101 / after:filing:20200101Date bounds (also passable as before/after params)

Usage Examples

1. Basic keyword search

在 Google Patents 检索 wireless earbuds 相关专利,返回 10 条

Action: {"q": "wireless earbuds", "num": 10}

2. Filter by country + status

检索美国授权的 wireless earbuds 专利

Action: {"q": "wireless earbuds", "country": "US", "status": "GRANT"}

3. Date range + sort newest

检索 2024 年至今公开的 wireless earbuds 专利,按最新排序

Display Rules

  1. Present results as a table: show publicationNumber, title, inventor, assignee, publicationDate/grantDate per item.
  2. Show totals: always state the total hit count from searchInformation/pagination and the current page range.
  3. Date formatting: render filingDate/publicationDate/grantDate/priorityDate as readable dates.
  4. Links: surface patentLink and pdf so the user can open the patent directly.
  5. Scholar results: when scholar=true, visually distinguish Scholar articles from patents.
  6. Large result sets: present a summary table first, note the total, and offer to expand specific patents.
  7. Expand via sibling skills: to get full bibliographic/legal/family detail for a found patent, direct the user to linkfox-zhihuiya-bibliography / linkfox-zhihuiya-legal-status; do not re-query this search skill for details.
  8. No fabrication: only display fields actually present in the response; never invent titles, dates, or assignees not returned.

Important Limitations

  • q is the primary search input: a query without q yields no meaningful results.
  • num range 10–100; values outside the range are rejected.
  • List-only output: this skill returns bibliographic list fields. Full text, legal status, family, and images must be fetched via dedicated linkfox-zhihuiya-* skills.
  • No auto-retry on empty/error: if the query returns no hits or an error, do not automatically swap keywords or rewrite the query; confirm with the user first (each call costs credits).
  • clustered currently only supports true per the upstream provider.
  • Date params use the priority|filing|publication:YYYYMMDD form, not bare dates.

User Expression & Scenario Quick Reference

Applicable — Discover patents on Google Patents:

User SaysScenario
"检索 wireless earbuds 的专利"Basic keyword search
"查谷歌专利" / "Google Patents 搜一下"General patent search
"美国授权的 XX 专利"Country + status filter
"2024 年至今公开的 XX 专利"Date range filter
"受让人是 Apple 的专利"Assignee search
"翻到第 2 页"Pagination

Not applicable — Needs beyond Google Patents list search:

  • Bibliographic detail / full text / legal status of a known patent number (use linkfox-zhihuiya-bibliography etc.)
  • Image-based patent search (use linkfox-zhihuiya-patent-image-search)
  • Zhihuiya Analytics expression search with field-scoped boolean syntax (use linkfox-zhihuiya-retrieval-patent-search)

Boundary judgment: When the user wants to discover patents by keyword/inventor/assignee/country/date on the public Google Patents corpus → this skill. When they have a patent number and want its detailed metadata → the linkfox-zhihuiya-* skills.
