Zhihuiya Patent Family Explorer

This skill guides you on how to query patent family information via the Zhihuiya (PatSnap) platform, helping users discover Simple Family, INPADOC Family, and PatSnap Family members for given patents.

调用方式

• API 端点：POST /zhihuiya/patentFamily（完整参数/响应/错误码见 references/api.md）
• Python 脚本：python scripts/zhihuiya_patent_family.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；需要继续检索时先向用户说明会产生额外消耗。 单专利限制：本接口消耗积分多，每次只能传 1 个专利；如需检测多个，必须经过用户明确同意，并分多次请求。

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-zhihuiya-patent-family-<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。

解决认证和积分问题

发生以下异常情况时，采用以下措施来处理：

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
• 响应提示积分或余额不足：消息含"积分余额不足/计费不足/余额不足/quota exceeded/insufficient balance/套餐到期/需充值/请充值"，或类似含义的内容。

措施

• 优先采用skill内的 onboarding.md 引导解决问题。
• 如找不到 onboarding.md 文件，则加载 /linkfox-onboarding 这个skill并根据它的引导来处理。如未安装请先安装：
  • 下载 https://agent-files.linkfox.com/skills/linkfox-onboarding/release.zip，解压后安装这个skill。如需用户授权才可下载，要询问用户获得授权，你不能自己放弃下载。
• 兜底措施：仅当前面两个措施经过所有努力都走不通时，才提示用户依据 https://skill.linkfox.com/linkfoxskills/guide.htm 指引获取API Key，或去 https://os.linkfox.com/ 补充积分。

Core Concepts

A patent family is a collection of patent documents that are related to each other by priority claims. Different family definitions capture different scopes of relatedness:

• Simple Family: Patents sharing exactly the same set of priority applications. These are typically direct equivalents filed in different countries.
• INPADOC Family: A broader grouping defined by the European Patent Office that links patents sharing at least one common priority, even indirectly.
• PatSnap Family: A proprietary family definition by PatSnap (Zhihuiya) that extends INPADOC logic with additional heuristics to capture continuations, divisionals, and other related filings.

Each patent in the response carries its own simpleFamilyId, inpadocFamilyId, and patsnapFamilyId, which serve as unique identifiers for the family group under each definition.

Parameter Guide

You must supply at least one of the two lookup parameters. If both are provided, patent ID takes precedence.

Rules:

1. At least one of patentId or patentNumber must be provided.
2. If both are provided, the API uses patentId and ignores patentNumber.
3. Only one patent may be passed per request. If the user has multiple patents, obtain explicit consent and make a separate call for each.

单专利限制：本接口消耗积分多，如需检测多个，必须经过用户明确同意，并分多次请求。每次调用仅可传入 1 个专利（patentId 与 patentNumber 均不可逗号分隔多个）。

Response Fields

Usage Examples

1. Look up family members by publication number

"Find the patent family for US10000001B2"

Call with:

{"patentNumber": "US10000001B2"}

3. Look up by patent ID

"Get the patent family for patent ID 5af83e12-xxxx-xxxx-xxxx-xxxxxxxxxxxx"

Call with:

{"patentId": "5af83e12-xxxx-xxxx-xxxx-xxxxxxxxxxxx"}

4. Compare family scopes

"I want to see how Simple Family vs. INPADOC Family differs for US20200012345A1"

Call with:

{"patentNumber": "US20200012345A1"}

Then compare simpleFamily and inpadocFamily arrays in the response.

Display Rules

1. Present data clearly: Show patent family results in well-structured tables. Group by family type (Simple, INPADOC, PatSnap) when the user asks for comparison.
2. Summarize counts: Always state how many family members were found under each family type so users can quickly gauge geographic spread.
3. Highlight jurisdictions: When listing family members, call out the countries/regions covered to help users understand the patent's geographic protection scope.
4. Error handling: When the API returns an error or empty results, explain the likely cause (invalid patent number format, patent not found in database, etc.) and suggest corrections.
5. Single-patent results: Each call returns a single patent's family data; present it clearly.
6. No subjective legal advice: Present factual family data only. Do not provide legal opinions on patent scope, validity, or infringement.

Important Limitations

• Lookup only: This tool retrieves family information for known patents. It cannot perform keyword-based patent searches or full-text queries.
• Single patent per request: Only one patent ID or publication number may be passed per call (no comma-separated batches).
• Data source: Family data comes from the Zhihuiya (PatSnap) database and may have a slight delay relative to the very latest patent office publications.
• Family member detail: The family member arrays contain summary objects. For full bibliographic data on a specific family member, a separate lookup may be required.

User Expression & Scenario Quick Reference

Applicable -- Patent family and equivalents lookup:

Not applicable -- Needs beyond patent family lookup:

• Full-text patent search by keywords or classification codes
• Patent valuation or litigation data
• Freedom-to-operate or infringement analysis
• Patent application filing or prosecution

积分消耗规则

按动态规则计费：消耗积分 = 81 × 返回data条数。每条为 1 条专利同族结果

重要：本技能的服务按倍数动态计算，可能一次性消耗大量积分，必须提醒用户，由用户决定是否继续。

单专利限制：本接口消耗积分多，如需检测多个，必须经过用户明确同意，并分多次请求。
