智慧芽-专利法律状态查询

从智慧芽（PatSnap）数据库查询专利法律状态信息。当用户提到专利法律状态、专利有效性核查、专利状态查询、专利事件历史、简单法律状态、转让、许可、质押、异议、诉讼、复审等法律事件、patent legal status, patent validity, patent events, transfer/license/pledge, PatSnap, patent status lookup时触发此技能。当用户询问专利是否处于有效、无效、审中、过期、授权、撤回或撤销状态，或想通过专利ID或公开号查询法律状态时也应触发。

Zhihuiya Patent Legal Status

This skill guides you on how to query patent legal status information via the Zhihuiya (PatSnap) platform, helping users quickly determine the current legal standing and event history of one or more patents.

调用方式

• API 端点：POST /zhihuiya/legalStatus（完整参数/响应/错误码见 references/api.md）
• Python 脚本：python scripts/zhihuiya_legal_status.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。

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-legal-status-<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

The Zhihuiya Patent Legal Status tool returns three layers of legal information for each patent:

1. Simple Legal Status -- A high-level summary of the patent's current standing (e.g., Active, Inactive, Pending, Undetermined, PCT designated period, PCT designated expiration).
2. Legal Status -- A detailed status describing the patent's lifecycle stage (e.g., Published, Examining, Granted, Abandoned, Withdrawn, Rejected, Expired, Revoked, Ceased, Restoration, etc.).
3. Legal Events -- Specific legal actions that have occurred on the patent (e.g., Transfer, License, Pledge, Opposition, Litigation, Re-examination, Customs, Preservation, Invalid-procedure, Oral-procedure, Declassification, Double application, Trust).

Patent identification: Patents can be looked up by either patent ID or publication (announcement) number. When both are provided, patent ID takes priority. Multiple values can be submitted in a single request (comma-separated, up to 100).

Parameter Guide

Parameter	Required	Description
patentId	Conditionally	Patent ID. At least one of patentId or patentNumber must be provided. Comma-separated for multiple values, up to 100.
patentNumber	Conditionally	Publication (announcement) number. At least one of patentId or patentNumber must be provided. Comma-separated for multiple values, up to 100.

• If the user provides a publication number (e.g., CN115xxxxxxA, US11xxxxxxB2, EP3xxxxxxA1), use patentNumber.
• If the user provides an internal patent ID, use patentId.
• When both are supplied, patentId takes precedence.

Response Fields

Field	Description
patentId	The patent's internal ID
pn	Publication (announcement) number
simpleLegalStatus	High-level status: Active, Inactive, Pending, Undetermined, PCT designated period, PCT designated expiration
legalStatus	Detailed lifecycle status (Published, Examining, Granted, Abandoned, Withdrawn, Rejected, Expired, Revoked, Ceased, etc.)
eventStatus	Legal events (Transfer, License, Pledge, Opposition, Litigation, Re-examination, etc.)
legalDate	Date of the most recent legal status update

Usage Examples

1. Check whether a single patent is still active

text

Query the legal status for patent publication number CN115000000A.

2. Batch-check legal status for multiple patents

text

Look up the legal status for patents US11000000B2, EP3000000A1, and CN115000001A.

3. Identify legal events on a patent

text

Has patent CN115000000A been involved in any litigation, transfer, or pledge events?

4. Determine if a patent has expired or been revoked

text

Check if patent US10000000B1 is expired, revoked, or still in force.

5. Look up patents by patent ID

text

Query the legal status for patent IDs abc123, def456.

Display Rules

1. Present data clearly: Show results in a structured table. Include the publication number, simple legal status, detailed legal status, and legal events for each patent.
2. Translate status values: When the user's language preference is clear, present status labels in that language while keeping the canonical English value in parentheses for precision.
3. Highlight key findings: If the user is checking validity, prominently state whether each patent is Active, Inactive, or Pending at the top of the response.
4. Legal date context: When legalDate is available, include it so users know how recent the status information is.
5. Error handling: If the query fails or returns no results, explain the possible reasons (invalid patent number format, patent not found in database) and suggest the user double-check the input.
6. Volume notice: When querying many patents, present a summary table and note the total count returned.

Important Limitations

• Up to 100 patents per request: The maximum number of patent IDs or publication numbers in a single call is 100.
• At least one identifier required: Either patentId or patentNumber must be provided; the request will fail if both are empty.
• Patent ID priority: When both patentId and patentNumber are provided, the system uses patentId and ignores patentNumber.
• Data coverage: Results depend on the Zhihuiya (PatSnap) database coverage; some very recent filings may not yet be reflected.

User Expression & Scenario Quick Reference

Applicable -- Queries about patent legal standing and events:

User Says	Scenario
"Is this patent still valid/active"	Simple legal status check
"What is the legal status of patent XX"	Detailed status lookup
"Has this patent been transferred or licensed"	Legal event query
"Check if these patents are expired"	Batch validity check
"Any litigation on this patent"	Legal event filtering
"Patent legal status for CN115XXXXXXA"	Direct publication number lookup

Not applicable -- Needs beyond patent legal status:

• Patent search by keyword, classification, or applicant name
• Patent full-text or claims retrieval
• Patent valuation or commercial analysis
• Freedom-to-operate (FTO) analysis
• Patent family or citation analysis

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 条专利法律状态结果

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。
