# stocks.patents USPTO patent activity associated with a public company. Pass ticker and optionally a from/to window (YYYY-MM-DD; defaults to ~2 years); returns each record with the application number, patent number (when granted), the filing company name(s), description/title, patent type, filing status, filing and publication dates, and a document URL. A company-level innovation/R&D signal (distinct from our key Agent View of the PolicyLayer registry record for `stocks.patents`. HTML page: https://policylayer.com/tools/io-github-2s-io-mcp/stocks.patents ## Facts - Tool: `stocks.patents` - Server: Mcp (`@2sio/mcp`) — https://policylayer.com/tools/io-github-2s-io-mcp.md - Install: `npx -y @2sio/mcp` - Homepage: https://github.com/2s-io/sdk - Risk category: Read (Low risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Allowed ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "stocks.patents", "arguments": {} } } ``` ## Why stocks.patents is rated Low The tool queries and returns historical patent information from public USPTO records. It performs a read-only lookup with optional filtering by ticker and date range. There are no side effects, no data modification, no code execution, and no financial transactions. The severity is low because the data is already public and querying it poses minimal risk even if misused by an AI agent. From the tool's own definition: "Tool retrieves USPTO patent activity data for public companies—'returns each record with the application number, patent number...filing and publication dates, and a document URL.' This is a data query operation with no modification, deletion, or execution…" ## Use case AI agents call stocks.patents to retrieve information from Mcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**.
