WHAT EVERY PATENT INCLUDES

The full record, ready to use

Every patent comes complete, so you build a search index or a dataset with no second call. The same record as CSV, ready for Sheets or a database:

Or the same record as JSON:

FAIR PLAY

When a paid patent database is the better pick: you need full claims text, legal status and litigation history, complete family and citation trees, or licensing and assignment records with a contract behind them. Google Patents gives you the title, abstract snippet, inventor, assignee, dates, figures, and the PDF, which is what most search and monitoring work needs, but it is not a full legal patent database.
