Appeal No. 1998-2360 Application No. 08/604,976 ahead of the leading, negative exposure blade where it would be provided with a negative exposure to establish a progressively increasing order of blade exposures. Second, the third blade may be placed between the negative exposure blade and the zero exposure blade where it would also be provided with a negative exposure to establish a progressively increasing order of blade exposures. Third, the third blade may be placed behind the zero exposure blade where it would be provided with a positive exposure to establish a progressively increasing order of blade exposures. Obviously, the choice of either the first or second locations would not result in appellants= invention, and the selection of the third location would amount to hindsight and thus would be improper as previously noted.
