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.Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 NextLast modified: November 3, 2007
