💡 AI Hint: Search Japanese patents / utility models by keyword (matches title, abstract and other indexed text). Returns up to count records, each with title, applicants, number variants, dates and FI classifications. Use a specific keyword: very broad terms can match too many records to return.
⚠️ Common errors: 422: Keyword matched too many results to return — use a more specific keyword
