Appeal No. 94-0869 Application No. 07/517,719 'substantially spherical,' and does not provide any electron photomicrographs of the claimed silica particles that would serve as a basis for comparing their morphology with the silica particles of Winyall." Appellant points out that the present specification states that "EP 18,866, assigned to the assignee hereof, proposed certain homogeneous silica spheres having a mean particle size greater than 80 Fm, a BET surface area of 100 to 300 m /g and a density of approximately 0.29."2 In addition, appellant notes that a U.S. patent to Garvey discloses egg-shaped particles shown in Figures 2-3 as being "spheroidal." However, since this argument was not presented in appellant's principal or reply briefs, it is not properly before us. Ex parte Hindersinn, 177 USPQ 78, 80 (Bd. App. 1971). See also 37 CFR § 1.192(a). Furthermore, appellant has not established the requisite nexus between the claimed "[s]ilica beads having a substantially spherical morphology" and the silica particles of EP 18,866 and Garvey. The arguments presented at pages 3-5 of appellant's Request, with respect to page 5, lines 3-10 of our decision, are also presented for the first time and, therefore, not properly before us.
