USPTO has just enhanced their on line full text patent database. They now provide retrieval of the full text of US patents from US 3930271+ January 1976 onwards. Further the USPTO now provides images of US patents from US 1+ 1790 onwards..

The database consists of the full text of US patents (including utility, design, reissue, plant and SIR patents). The database is updated every Tuesday. Full text includes all bibliographic data, such as the inventor's name, the patent's title, and the assignee's name, as well as the abstract, the full description of the invention, and the claims. All of the words (text) in the patent are searchable.
