You can also access the U.S. Patent and Trademark Office database at  Additionally, google has a good interface that retrieves from the uspto database at

One way to more efficiently search the patent database is by limiting your search by classification and sub-class if possible.  In the pto database its just a component in the search string.  Once you find a patent that is directed to a technology that interests you, look at the 3 digit classification number that is listed on the face of the will be in a 123/456 format.  Your search can be narrowed in this manner.  Also, note that infringement is not an issue if a patent's term has expired.
