Searching for Patents
To find patents search by number, keyword, personal or organisation name, or by classification (see "More about patents and searching" below). Older patents can often be downloaded freely, but current patents need to be purchased. Useful sources are:

Access to US and European patents and patent applications.
Google Patent Search
