If you are thinking about creating your own design patent for a webpage on your site, Google provides an example.
Google's front page design patent is available from the United States Patent and Trademark Office. A summary is also available. (I was unable to view these with Firefox 3.5.2 and Quicktime 7.6.2 that comes with OS X 10.5.8, but could with Safari 4.0.3 for some reason, so I include the images here in case anyone else has trouble viewing them.)
The claim is "The ornamental design for a graphical user interface for a display screen of a communications terminal, as shown and described." The description is "A portion of the disclosure of this patent document contains material to which a claim for copyright and trademark is made. The copyright and trademark owner has no objection to the reproduction of the patent document or the patent disclosure, as it appears in the U.S. Patent Office records, but reserves all other copyright and trademark rights whatsoever. The single view is a front view of a graphical user interface for a display screen of a communications terminal. The broken line of the display of certain words and numbers in the drawing are for illustrative purposes only and form no part of the claimed design."
Note that all references to Google (and Froogle) in the design are not part of the patent and that the patent is based on the old design of the front page, because the patent was filed March 7, 2006.
