However, the Examiner concludes, it would have been obvious "to determine the size of the hub, hub member, and flange . . . disclosed by Kato et al by routine experimentation, by keeping in account the disk elastic properties and the need for maximize [sic] the amount of usable disk area, as a change in size of a structure known in the prior art involves only ordinary skills in the art" (FR2; EA4). The Examiner states that one of ordinary skill in the art "would have been motivated to do so to provide adequate connection and support of the sheet . . . without excessively limiting the usable area of the sheet, as required by the well known trend in the art toward maximization of the amount of information storable on disks" (FR2-3; EA4). Appellants argue that the industry standard prior art 2 MByte 3.5" (89 mm) diskette has a hub having a diameter of approximately 29.0 mm and that the Examiner has provided no motivation to decrease the diameter of the hub. Appellants refer to the affidavit under 37 CFR � 1.132 of James K. Knudsen (Paper No. 12). - 5 -Page: Previous 1 2 3 4 5 6 7 8 9 10 NextLast modified: November 3, 2007
