Google Patent SearchDebuting in December 2006, Google's new patent search engine is a painless way to search and view patents issued in the U.S. from 1790 to the present (excluding recent applications). You can search for patents by keyword, patent number, title, inventor, assignee, classification (both U.S. and international), issue date, and filing date.
Unlike the U.S. Patent and Trademark Office's database, you can easily view the patents in Google's engine without having to download a special viewer. In addition, click the "Download PDF" button on the Google page to download the patent in PDF format to your computer.
