                Appeal No. 2005-1024                                                                                  Page 8                    
                Application No. 10/156,291                                                                                                      


                characterized by Koeniger as “hard” when in that state.3   Koeniger’s lens does not                                             
                become “soft” until after it has taken up aqueous humor in the eye, in which state it                                           
                would not appear to be “internally dry.”  The anticipation rejection thus cannot be                                             
                sustained.  Further, inasmuch as the examiner has not provided any explanation as to                                            
                why it would have been obvious to make Koeniger’s lens at once both soft and internally                                         
                dry, it follows that the obviousness rejection based on Koeniger also cannot be                                                 
                sustained.                                                                                                                      
                         The examiner has also rejected claims 26-28 as being unpatentable over any of                                          
                Burk, Volk or Koziol in view of either Mazzocco or Schlegel.  For the reasons which                                             
                follow, we shall sustain the rejection based upon Burk, Volk or Koziol in view of                                               
                Mazzocco but not the rejection based on Burk, Volk or Koziol in view of Schlegel.                                               
                         Each of the primary references Burk, Volk and Koziol discloses an aspherical                                           
                intraocular lens, with the shape selected so as to achieve desired vision correction or                                         
                refraction.  None of these references discloses a molded soft intraocular lens molded                                           
                from a soft material, as also required in claims 26-28.  Koziol discloses that the optical                                      
                elements “can be ground or molded from suitable optical material such as optical glass                                          
                or polymeric material such as polymethylmethacrylate” (column 4, lines 1-3), Volk                                               
                discloses that the lens may be made of polymethyl methacrylate or other materials,                                              


                         3 While the term “soft” is a term of degree, one of ordinary skill in the art of intraocular lenses                    
                would certainly understand a “soft” intraocular lens to be one which is sufficiently soft and pliable to permit                 
                folding to reduce its size during insertion into the eye.  Within this context, the examiner’s position that                    
                Koeniger’s dry HEMA lens, characterized by Koeniger as “hard,” is “soft” (answer, page 8) is unreasonable                       
                on its face.
