Implementation Reference
- src/index.ts:259-264 (handler)The handler function for the 'get_top_assignees' tool. It constructs search parameters using buildCommonSearchParams, sets a default language of 'en' if not provided, and delegates to the shared callPatsnapApi helper for the 'applicant-ranking' endpoint.async function getTopAssignees(args: LangPatentArgs): Promise<ServerResult> { const params = buildCommonSearchParams(args); if (!args.lang) { // Add default lang if not provided params.append('lang', 'en'); } return callPatsnapApi('applicant-ranking', params, 'get top assignees');
- src/index.ts:366-370 (registration)Registration of the 'get_top_assignees' tool in the ListToolsRequestHandler response. Specifies the tool name, description, and input schema.{ name: 'get_top_assignees', description: 'Shows the top companies (assignees) with the largest patent portfolios. Identify largest players and competitive threats. Returns up to the top 10 assignees. Note: Search must contain either keywords or IPC.
