Additional Informational Links Below is the link to Google's Patent Search which is easy to use and works well with the patent number, just the date, and / or relevant keywords. Try it first Below is the link to the US Patent office website where if you have the patent number you can view the patent papers. With only the date it becomes a more involved process at this site and you can find out information about doing it there. Also please note there are instructions on the site for downloading the tiff program that you will need to view the patent files if you use this site. Google is easier.
