query patent data via the patentsview api

Steps

1. No authentication is required; PatentsView is a public USPTO-funded API.
2. POST to /api/v1/patent/ (or GET with URL-encoded parameters) with a q (query) object, an f (fields) array specifying which fields to return, and optional o (options) for pagination (per_page, page).
3. Construct query predicates using PatentsView's query syntax, e.g., {"_text_all":{"patent_abstract":"CRISPR"}} for full-text search or {"patent_number":"10000000"} for a direct lookup.
4. Join to inventor, assignee, or CPC classification data by including the relevant nested field names in the f array (e.g., inventors.inventor_last_name, assignees.assignee_organization).
5. Page through results using the total_patent_count in the response metadata divided by per_page to determine total pages; the API returns up to 1000 results per request.
