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 records with a contract behind them. Google Patents gives you the title, abstract snippet, inventor, assignee, dates, figures, and the PDF. That covers most search and monitoring work, but it is not a full legal patent database.
