Zhihuiya Patent Legal 状态

This 技能 图形界面des you on how to 查询 patent legal 状态 in格式化ion via the Zhihuiya (PatSnap) 平台, helping users quickly determine the current legal standing and event 历史 of one or more patents.

Core Concepts

The Zhihuiya Patent Legal 状态 工具 returns three layers of legal in格式化ion for each patent:

Simple Legal 状态 -- A high-level summary of the patent's current standing (e.g., Active, Inactive, Pending, Undetermined, PCT de签名ated period, PCT de签名ated expiration). Legal 状态 -- A detAIled 状态 describing the patent's lifecycle stage (e.g., Published, Examining, Granted, Abandoned, Withdrawn, Rejected, Expired, Revoked, Ceased, Restoration, etc.). Legal 事件 -- 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 应用, Trust).

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

Parameter 图形界面de 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 机器人h are supplied, patentId takes precedence. 响应 Fields Field Description patentId The patent's internal ID pn Publication (announcement) number simpleLegal状态 High-level 状态: Active, Inactive, Pending, Undetermined, PCT de签名ated period, PCT de签名ated expiration legal状态 DetAIled lifecycle 状态 (Published, Examining, Granted, Abandoned, Withdrawn, Rejected, Expired, Revoked, Ceased, etc.) 事件tatus Legal 事件 (Transfer, License, Pledge, Opposition, Litigation, Re-examination, etc.) legalDate Date of the most recent legal 状态 更新 Usage Examples

• 检查 whether a single patent is still active

查询 the legal 状态 for patent publication number CN115000000A.

• Batch-检查 legal 状态 for multiple patents

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

• Identify legal 事件 on a patent

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

• Determine if a patent has expired or been revoked

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

• Look up patents by patent ID

Display Rules Present data clearly: Show 结果s in a structured table. Include the publication number, simple legal 状态, detAIled legal 状态, and legal 事件 for each patent. Translate 状态 values: When the user's language preference is clear, present 状态 labels in that language while keeping the canonical English value in parentheses for precision. Highlight key findings: If the user is 检查ing validity, prominently 状态 whether each patent is Active, Inactive, or Pending at the top of the 响应. Legal date 上下文: When legalDate is avAIlable, include it so users know how recent the 状态 in格式化ion is. Error handling: If the 查询 fAIls or returns no 结果s, explAIn the possible reasons (invalid patent number 格式化, patent not found in database) and suggest the user double-检查 the 输入. Volume notice: When 查询ing many patents, present a summary table and note the total count returned. 导入ant Limitations Up to 100 patents per 请求: 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 请求 will fAIl if 机器人h are empty. Patent ID priority: When 机器人h patentId and patentNumber are provided, the 系统 uses patentId and ignores patentNumber. Data coverage: 结果s depend on the Zhihuiya (PatSnap) database coverage; some very recent filings may not yet be reflected. User Expression & Scenario Quick Reference
