uspto_search_applications
Read-only
Search USPTO patent applications with boolean queries, wildcards, phrases, and field-specific filters. Narrow results by date or number ranges and sort output.
Instructions
Search USPTO patent applications using ODP query syntax (POST). The q param supports opensearch DSL: boolean (AND/OR/NOT), wildcards (* ?), exact phrases (""), field:value, ranges ([from TO to]), comparisons (>=600). Filters narrow results by field value. Range filters narrow by date/number range. All params are optional -- an empty search returns recent applications.
