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.

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. Multiple values are comma-separated (e.g., "US10000001B2,EP3000001A1").
4. The upper limit is 100 patents per request.

Response Fields

Usage Examples

1. Look up family members by publication number

"Find the patent family for US10000001B2"

Call with:

{"patentNumber": "US10000001B2"}

2. Look up families for multiple patents at once

"Show the INPADOC family for these patents: EP3000001A1, CN112345678A, JP2020123456A"

Call with:

{"patentNumber": "EP3000001A1,CN112345678A,JP2020123456A"}

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. Batch result organization: When querying multiple patents, organize results per patent so users can easily find each one.
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.
• Batch limit: A maximum of 100 patent IDs or publication numbers per request.
• 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
