Google Patents Search API

Google Patents search results for any query, inventor or assignee, with filters for patent office (US, EP, WO, CN, ...), priority, filing or publication date range, granted or application, utility or design, original language and sort order: publication number, title, snippet, first inventor and assignee, priority, filing, publication and grant dates, PDF link, thumbnail and figure images, per-country family status, the total result count, plus the top assignees, inventors and CPC classes among the matches. 10 to 100 results per page; Google Patents stops at the 1,000th result. Use Google Patent Details for one patent's claims, citations and family. Empty pages, blocked or verification pages are never charged.
