Zhihuiya Patent Citations Explorer

This skill guides you on how to query patent citation data from Zhihuiya (PatSnap), helping users understand the citation landscape of specific patents.

Core Concepts

Patent citation analysis reveals how influential a patent is within its technology domain. When Patent B references Patent A in its prior art section, Patent A is said to be "cited by" Patent B. A higher citation count generally indicates greater technological significance and broader industry influence.

Key metrics:

• 3-year citations (citedBy3y): Number of times the patent was cited within 3 years of publication. Indicates early-stage impact.
• 5-year citations (citedBy5y): Number of times the patent was cited within 5 years. Indicates medium-term influence.
• Simple family citations (citedBySimpleFamily): Count of simple patent family members that cite the patent.
• INPADOC family citations (citedByInpadocFamily): Count of INPADOC patent family members that cite the patent.
• PatSnap family citations (citedByPatsnapFamily): Count of PatSnap-defined patent family members that cite the patent.

Parameter Guide

You must provide at least one of the following identifiers. If both are supplied, patent ID takes priority.

Important: At least one of patentId or patentNumber is required. When the user provides a publication number (e.g., "US10123456B2"), use patentNumber. When they provide internal IDs, use patentId.

Usage Examples

1. Single patent citation lookup by publication number

Query: "How many citations does patent US10123456B2 have?"

{
  "patentNumber": "US10123456B2"
}

2. Multiple patents citation comparison

Query: "Compare citations for CN112345678A and CN113456789B"

{
  "patentNumber": "CN112345678A,CN113456789B"
}

3. Lookup by patent ID

Query: "Get citation data for patent ID abc123def456"

{
  "patentId": "abc123def456"
}

4. Batch query with multiple IDs

Query: "Citation info for these patent IDs: id001, id002, id003"

{
  "patentId": "id001,id002,id003"
}

Display Rules

1. Present data in tables: Show citation results in clear, structured tables. Include the publication number, 3-year citations, 5-year citations, and family citation counts.
2. Highlight key metrics: When comparing multiple patents, highlight the one with the highest citation counts.
3. Explain family types: If the user is unfamiliar with patent families, briefly explain the difference between Simple, INPADOC, and PatSnap family definitions.
4. Citing patent details: If the response includes a citedByPatents array with details of citing patents, present them in a sub-table or expandable list.
5. Error handling: When a query fails, explain the reason based on the response and suggest checking whether the patent number or ID is correct.
6. No subjective advice: Present factual citation data without making judgments about patent value or investment decisions.

API Usage

This tool calls the LinkFox tool gateway API. See references/api.md for calling conventions, request parameters, and response structure. You can also execute scripts/zhihuiya_cited_by.py directly to run queries.
