There's a short article at http://www.sciam.com/2002/0202issue/0202patents.html on some of the worst patents of all time. My favorites are - 3 dimensional pie charts (U.S.: 5,491,779: "Three-Dimensional Presentation of Multiple Data Sets in Unitary Format with Pie Charts"; Richard D. Bezjian.) - training manuals (U.S.: 5,851,117: "Building Block Training Systems and Training Methods"; Keith A. Alsheimer and others.)
