Appeal No. 2002-0928 Application 09/315,251 particles. While Ozaki prepares a dispersion of zirconium oxide having a particle size of 5 nanometers in water using ultrasound, there is no evidence in the record which establishes that zirconium oxide of 5 nanometer particle size as dispersed by ultrasound is a "nanostructured material." Moreover, the dispersion obtained by Ozaki is subsequently dropped into a high boiling liquid to drive off water and form microspheres which ultimately have a particle size of "about 50 :m." The examiner has not adequately explained why the routineer would have halted Ozaki's process after forming the aqueous dispersion of zirconium oxide by ultrasound and then used the dispersion in Gitzhofer's process for a different purpose than that intended by Ozaki for their process. Accordingly, we find that the examiner has failed to make out a prima facie case of obviousness for the subject matter appellants claim to be their invention. Because we have found the examiner has failed to make out a prima facie case of obviousness, it is unnecessary for our decision to address the declarations under 37 C.F.R. § 1.132 which represent appellants' evidence of non-obviousness. NEW GROUND OF REJECTION Pursuant to our authority under 37 C.F.R. § 1.196(b), we enter the following new ground of rejection. Claims 1 through 5 and 8 through 12 are rejected under the judicially created doctrine of obviousness-type double patenting over the claims in U.S. Patent Number 6,025,034. 8Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 NextLast modified: November 3, 2007
