In order to decide whether an invention is patentable, the examiner “must ascertain what would have been obvious to one of ordinary skill in the art at the time the invention was made, and not to the inventor, a judge, a layman, those skilled in remote arts, or to geniuses in the art at hand.” Environmental Designs, Ltd. v. Union Oil Co., 713 F.2d 693; 218 USPQ 865 (Fed. Cir. 1983), cert. denied, 464 U.S. 1043 (1984).
