The second link below will take you to the US Patent and Trademark Office's (USPTO) web site, where you may search for additional information on specific patents. Note that not all patent information has been digitized as yet, so the information may not be available online. (Use the page's "Issued Patents" items to correlate items to the Connecticut web page's items.)
The third link below will take you to the Google Patent Search's web site, a complement to the U.S.Patent and Trademark Office's web site. As noted on the site's home page, Google and the USPTO have entered into an agreement to make bulk patent and trademark information available to the public at no charge.
