Google Patents Search

Google Patents 检索

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.
本技能可检索公开的Google Patents数据库,返回匹配专利的公开号、标题、发明人、受让人、日期、CPC分类及PDF链接。适用于跨境卖家在上架产品前进行自由实施(FTO)排查、现有技术检索以及专利侵权风险筛查。

Core Concepts

核心概念

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.
Google Patents检索会针对公开的Google Patents语料库执行查询(
q
参数)。查询支持Google Patents原生的高级语法(例如
owner:"company"
inventor:"name"
、日期范围)。结果以排序后的专利列表形式返回(可选择包含Google Scholar文章)。
本技能仅返回专利的著录字段列表。若要获取此处找到的特定专利的详细著录数据、全文、法律状态、专利族或图片,请将返回的
patentId
/
publicationNumber
传入对应的
linkfox-zhihuiya-bibliography
/
linkfox-zhihuiya-legal-status
/
linkfox-zhihuiya-patent-family
技能。

调用方式

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:本工具会消耗积分;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

  • 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

  • --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

Display Rules

展示规则

  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

    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.
  1. 以表格形式展示结果:每条结果显示
    publicationNumber
    title
    inventor
    assignee
    publicationDate
    /
    grantDate
    字段。
  2. 显示总数:始终说明
    searchInformation

  3. 日期格式化:将
    filingDate
    /
    publicationDate
    /
    grantDate
    /
    priorityDate
    格式化为易读的日期格式。
  4. 链接展示:显示
    patentLink
    pdf
    链接,方便用户直接打开专利。
  5. Scholar结果区分:当
    scholar=true
    时,在视觉上区分Scholar文章与专利。
  6. 大结果集处理:先展示摘要表格,说明总数,并提供展开特定专利的选项。
  7. 通过关联技能获取详情:若要获取已找到专利的完整著录/法律状态/专利族详情,请引导用户使用
    linkfox-zhihuiya-bibliography
    /
    linkfox-zhihuiya-legal-status
    技能;请勿重新调用本检索技能获取详情。
  8. 禁止编造内容:仅展示响应中实际存在的字段;不得编造未返回的标题、日期或受让人信息。

Important Limitations

重要限制

  • 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.
  • q
    是核心检索输入
    :未提供
    q
    参数的查询无法返回有意义的结果。
  • num
    参数范围为10–100
    ;超出范围的值会被拒绝。
  • 仅返回列表:本技能仅返回著录字段列表。全文、法律状态、专利族和图片必须通过专用的
    linkfox-zhihuiya-*
    技能获取。
  • 空结果/错误时不自动重试:若查询无结果或返回错误,请勿自动更换关键词或重写查询;需先与用户确认(每次调用都会消耗积分)。
  • 上游服务商当前仅支持
    clustered=true
  • 日期参数需使用
    priority|filing|publication:YYYYMMDD
    格式
    ,不能仅传入日期。

User Expression & Scenario Quick Reference

用户表述与场景速查

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.
适用场景 — 在Google Patents上检索专利:
User SaysScenario
"检索 wireless earbuds 的专利"基础关键词检索
"查谷歌专利" / "Google Patents 搜一下"通用专利检索

"2024 年至今公开的 XX 专利"按日期范围筛选
"受让人是 Apple 的专利"受让人检索
"翻到第 2 页"分页检索
不适用场景 — 超出Google Patents列表检索的需求:
  • 已知专利号的著录详情/全文/法律状态(使用
    linkfox-zhihuiya-bibliography
    等技能)
  • 基于图片的专利检索(使用
    linkfox-zhihuiya-patent-image-search
    技能)
  • 使用字段范围布尔语法的智汇芽分析表达式检索(使用
    linkfox-zhihuiya-retrieval-patent-search
    技能)
边界判断:当用户希望通过关键词/发明人/受让人/国家/日期在公开的Google Patents语料库中发现专利时→使用本技能。当用户已有专利号并希望获取其详细元数据时→使用
