Google Patent

Google has now extended its tentacles into the area of patent research. Google Patent allows patent researchers to search the entire collection of patents made available by the United States Patent and Trademark Office. Dates of coverage extend from patents issued during the 1790s to those issued by the middle of 2006.

Google Patent does not currently include patent applications, international patents, or U.S. patents issued during the past few months, but it anticipates expanding its coverage sometime in the future.
