Google Public Policy Blog: “When we launched Google Patent Search in 2006, we wanted to make it easier for people to understand the world of inventions, whether they were browsing for curious patents or researching serious engineering. Recently, we’ve also worked on a number of public data search features, as well as experimental features like the Public Data Explorer…That’s why we’re proud to announce that the USPTO and Google are making this data available for free at http://www.google.com/googlebooks/uspto.html. This includes all granted patents and trademarks, and published applications — with both full text and images. And in the future we will be making more data available including file histories and related data.”
