Google Patent Search
December 18, 2006 | Levent OZLER
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).

The goal with Google Patent Search is to make this public domain government information more easily accessible using web search technology.
