Google announced a new search feature on Thursday, allowing internet users to search through millions of U.S patents issued over the past 200 years.
The patent search site, launched as a beta on Wednesday night, is designed to sift through approximately 7 million U.S. patents by a variety of categories including filing date, issue date, patent number and inventor.
The Mountan View Calif.-based firmâ€™s new tool looks back at inventions all the way to the 1790s but does not include patent applications, international patents or U.S. patents issued since mid-2006.
The company said in its official blog that it is continuing to expand the functionality.
