Google Now Searches More Than 7 Million US Patents

December 14, 2006

Have you ever wondered who invented the zipper, the lawn mower – or maybe the eraser? Well now Google makes it easier than ever to search the over 7 million patents granted by the United States Patent and Trademark Office (USPTO). With patents dating back to 1790, users can search inventions just like they search on Google today, or by criteria, such as patent number, inventor, or filing date. Our goal with Google Patent Search is to make this public domain government information more easily accessible using web search technology.
