USPTO issues 3,500 to 4,000 patents per week,and the USPTO database contains more than 6.5 million patents filed since 1790 by inventors from more than 170 countries. USPTO provides full-text access to patents published after 1976, which can be searched by almost every data field of the patent. USPTO also provides scanned images of the patents published between 1790 and 1976, which can be searched by issue date, patent number, and current US patent classification.
