History and background

The service was launched on December 14, 2006. Google says it uses "the same technology as that underlying Google Books",[3] allowing scrolling through pages, and zooming in on areas.[4] The images are saveable as PNG files.

Early review and criticisms

The indexing is not perfect. Reportedly, as of December 14, 2006, not all IBM patents were locatable, as searching for IBM patents retrieved only 1,197 results on Google Patents, but that IBM received nearly 3,000 patents in 2005 alone.[5]

In terms of response time, the performance of Google Patents was considered in 2007 to be very good.[6]
