Zhihuiya Patent Claims Data

This skill guides you on how to retrieve and present patent claims data from the Zhihuiya (PatSnap) patent database, helping IP professionals, patent analysts, and R&D teams quickly access the claims section of any patent.

Core Concepts

Patent claims define the legal scope of protection granted by a patent. They are the most critical part of a patent document for infringement analysis, freedom-to-operate assessments, and prior art comparisons. This tool retrieves the full set of claims for one or more patents by their patent ID or publication number.

Family substitution: When a patent's claims are unavailable in the database, you can optionally request that claims from a related family member patent be returned instead. This is controlled by the replaceByRelated parameter.

Data Fields

| Field | API Name | Description | Example | |-------|----------|-------------|---------| | Patent ID | patentId | Internal Zhihuiya patent identifier | 98a1b2c3-... | | Publication Number | pn | Publication or grant number of the patent | CN115000000A | | Related PN | pnRelated | Publication number of the family member used as substitute (only present when family substitution occurred) | US20230001234A1 | | Claims | claims | Array of claim objects containing the claim text and metadata | [...] | | Claim Count | claimCount | Total number of claims in the patent | 15 |

Parameter Guide

Required (at least one)

You must provide at least one of the following two parameters. If both are provided, patentId takes priority.

| Parameter | Description | Format | |-----------|-------------|--------| | patentId | One or more Zhihuiya patent IDs | Comma-separated string, max 100 entries | | patentNumber | One or more publication/grant numbers | Comma-separated string, max 100 entries |

Optional

| Parameter | Description | Values | |-----------|-------------|--------| | replaceByRelated | Whether to substitute with a family member's claims when the target patent's claims are unavailable | 1 = yes, 0 = no (default) |

How to Choose Between patentId and patentNumber

Use patentNumber when the user provides a publication or grant number (e.g., CN115000000A, US11234567B2). This is the most common scenario.
Use patentId when the user provides an internal Zhihuiya identifier, typically obtained from a previous Zhihuiya search result.
When the user provides both, pass both and the API will prefer patentId.

Usage Examples

1. Single patent by publication number

{"patentNumber": "CN115000000A"}

2. Multiple patents by publication number

{"patentNumber": "CN115000000A,US20230001234A1,EP4000000A1"}

3. Single patent by patent ID

{"patentId": "98a1b2c3-xxxx-xxxx-xxxx-xxxxxxxxxxxx"}

4. With family substitution enabled

{"patentNumber": "CN115000000A", "replaceByRelated": "1"}

5. Batch query with family substitution

{"patentNumber": "CN115000000A,JP2023100000A", "replaceByRelated": "1"}

Display Rules

Present claims clearly: Display claims in a numbered list preserving the original claim numbering. Use indentation or formatting to distinguish independent claims from dependent claims where possible.
Highlight claim count: Always state the total number of claims returned for each patent.
Family substitution notice: If pnRelated is present in a result, explicitly inform the user that the claims shown are from a family member patent and provide the family member's publication number.
Batch results: When multiple patents are queried, organize results by patent with clear headings showing the publication number.
Error handling: When a query fails, explain the reason based on the response and suggest the user verify the patent number format or try enabling family substitution.
No subjective analysis: Present the raw claim text without legal interpretation unless the user specifically requests analysis.

Important Limitations

At least one identifier required: Either patentId or patentNumber must be provided; omitting both will result in an error.
Batch limit: A maximum of 100 patents can be queried in a single request.
Claims availability: Not all patents have claims data available. Use replaceByRelated = 1 to attempt family member substitution when claims are missing.
Claim object structure: The individual claim objects within the claims array may vary in structure depending on the patent office and data source.

User Expression & Scenario Quick Reference

Applicable -- Patent claims retrieval and analysis:

| User Says | Scenario | |-----------|----------| | "Show me the claims of patent XX" | Single patent claims lookup | | "Get the claim text for these patents" | Batch claims retrieval | | "How many claims does patent XX have" | Claim count query | | "What are the independent claims of XX" | Claims retrieval + display | | "Compare claims of patent A and patent B" | Multi-patent claims retrieval | | "The claims are not available, try a family member" | Family substitution query | | "Patent claim scope", "claim language" | Claims retrieval |

Not applicable -- Needs beyond patent claims data:

Patent search or discovery (finding patents by keyword/topic)
Patent legal status or prosecution history
Patent citation or reference analysis
Patent full-text beyond claims (abstract, description, drawings)
Freedom-to-operate or infringement opinions (legal advice)
