sonesuke Patent Search
Search for patents from Google Patents using the google-patent-cli MCP server.
Purpose
Execute patent searches with various filters including query, assignee, country, and date range.
MCP Tool
Uses search_patents MCP tool provided by google-patent-cli.
Usage
Search for patents, then use the returned dataset name to query with Cypher:
patent_search({
query: "machine learning",
limit: 20
})
# Returns dataset name like "search-abc123"
# Then query with execute_cypher:
execute_cypher({
dataset: "search-abc123",
query: "MATCH (p:Patent) RETURN p.title, p.assignee LIMIT 5"
})
CRITICAL: After searching, always use execute_cypher to retrieve results.
Do NOT read the output JSON file directly. The JSON file is an internal
artifact — all data is available through cypher queries.
Result Retrieval Patterns
Use these cypher patterns to retrieve search results:
Total count:
MATCH (p:Patent) RETURN COUNT(*) AS count
Top 20 snippets for noise analysis:
MATCH (p:Patent) RETURN p.id, p.title, p.snippet, p.assignee LIMIT 20
Assignee breakdown:
MATCH (p:Patent) RETURN p.assignee, COUNT(*) AS count ORDER BY count DESC
Date range summary:
MATCH (p:Patent) RETURN p.filing_date, p.title LIMIT 10
