Zhihuiya Patent Legal Status

智慧芽（PatSnap）专利法律状态

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.
本技能将指导您如何通过智慧芽（PatSnap）平台查询专利法律状态信息，帮助用户快速确定一项或多项专利的当前法律状态及事件历史。

Core Concepts

核心概念

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Status -- A detailed status describing the patent's lifecycle stage (e.g., Published, Examining, Granted, Abandoned, Withdrawn, Rejected, Expired, Revoked, Ceased, Restoration, etc.).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).
智慧芽专利法律状态工具可为每项专利返回三层法律信息：
  1. Simple Legal Status -- 专利当前状态的高阶汇总（例如：Active（有效）、Inactive（失效）、Pending（审中）、Undetermined（待定）、PCT指定期间、PCT指定期满）。
  2. Legal Status -- 描述专利生命周期阶段的详细状态（例如：Published（已公开）、Examining（审查中）、Granted（已授权）、Abandoned（已放弃）、Withdrawn（已撤回）、Rejected（已驳回）、Expired（已过期）、Revoked（已撤销）、Ceased（终止）、Restoration（恢复）等）。
  3. Legal Events -- 专利发生过的具体法律行为（例如：Transfer（转让）、License（许可）、Pledge（质押）、Opposition（异议）、Litigation（诉讼）、Re-examination（复审）、Customs（海关备案）、Preservation（保全）、Invalid-procedure（无效程序）、Oral-procedure（口头审理）、Declassification（解密）、Double application（重复申请）、Trust（信托））。
专利标识：可通过专利ID或公开（公告）号查询专利。当两者同时提供时，以专利ID优先。单次请求可提交多个值（逗号分隔，最多100个）。

    patentId
    .
  • When both are supplied, 
    patentId
    takes precedence.
参数必填性描述
patentId条件必填专利ID。必须至少提供patentId或patentNumber其中一项。多个值用逗号分隔，最多100个。
patentNumber条件必填公开（公告）号。必须至少提供patentId或patentNumber其中一项。多个值用逗号分隔，最多100个。
  • 如果用户提供公开号（例如：CN115xxxxxxA、US11xxxxxxB2、EP3xxxxxxA1），使用

Usage Examples

使用示例

1. Check whether a single patent is still active
Query the legal status for patent publication number CN115000000A.
2. Batch-check legal status for multiple patents
Look up the legal status for patents US11000000B2, EP3000000A1, and CN115000001A.
3. Identify legal events on a patent
Has patent CN115000000A been involved in any litigation, transfer, or pledge events?
4. Determine if a patent has expired or been revoked
Check if patent US10000000B1 is expired, revoked, or still in force.
5. Look up patents by patent ID
Query the legal status for patent IDs abc123, def456.
1. 核查单个专利是否仍有效
Query the legal status for patent publication number CN115000000A.
2. 批量核查多项专利的法律状态
Look up the legal status for patents US11000000B2, EP3000000A1, and CN115000001A.
3. 查询专利的法律事件记录
Has patent CN115000000A been involved in any litigation, transfer, or pledge events?

Display Rules

展示规则

  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.
  1. 清晰呈现数据：以结构化表格展示结果，包含每项专利的公开号、简单法律状态、详细法律状态及法律事件。
  2. 状态值翻译：当明确用户语言偏好时，以该语言展示状态标签，同时保留规范英文值在括号内以确保准确性。
  3. 突出关键结论：如果用户核查有效性，在回复顶部显著标注每项专利是Active（有效）、Inactive（失效）还是Pending（审中）。
  4. 法律日期说明：若
    legalDate
    字段可用，需包含该信息，以便用户了解状态信息的时效性。
  5. 错误处理：若查询失败或无结果，说明可能原因（专利号格式无效、数据库中未找到该专利），并建议用户核对输入。
  6. 批量查询提示：当查询大量专利时，展示汇总表格并标注返回结果的总数。

Important Limitations

重要限制

  • 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.
  • 单次请求最多100项专利：单次调用中最多可提交100个专利ID或公开号。
  • 必须提供至少一个标识：
    patentId
    或
    patentNumber
    必须提供其中一项，若两者均为空，请求将失败。
  • 专利ID优先：当同时提供
    patentId
    和
    patentNumber
    时，系统将使用
    patentId
    并忽略
    patentNumber
    。
  • 数据覆盖范围：结果取决于智慧芽（PatSnap）数据库的覆盖范围，部分最新提交的专利可能尚未收录。
