In an attempt to overcome the above-noted deficiencies of Hentz, the examiner, pointing specifically to the disclosure of Hulderman in column 12, lines 15-37, directed to aligning and bonding the photomasks (314, 316) in position about the photoresist laminated shim stock (300), takes that position that [i]t would have been obvious to one having ordinary skill in the art to have employed the method and apparatus taught by Hentz et al. to bond substrates having substantially the same surface area, since Hulderman et al. suggest observing indicia through transparent portions of substrates to facilitate bonding of laminae having substantially the same surface areas [answer, page 4]. From our perspective, one of ordinary skill in the art would have recognized that the Hentz apparatus is not capable of use for aligning and adhering substrates, at least one of which is non-transparent, having approximately the same surface area and, thus, would not have been motivated to use it in such a manner for manufacturing a photomask covered assembly as taught by Hulderman. Further, given the very disparate teachings of Hentz and Hulderman, it is not apparent to us why one of ordinary skill in the art would have been led by 3The substrate (18) must be sufficiently large to extend over the indicator marks (52, 54) on the prisms (56), which fall well outside the cavities (28).Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 NextLast modified: November 3, 2007
