Appeal No. 1999-2277 Application 08/803,578 The signal terminals[] of the slider[] are directly connected to the signal electrodes[] on the wiring substrate[] by . . . using gold balls. . . . The grounding terminal[] of the slider[] is also directly connected to the grounding electrode[] on the wiring substrate[] by . . . ball bonding using a gold ball. Column 6, line 65, to column 7, lines 4. We find no evidence in Kudo that teaches or suggests that the gold ball bonding is used to attach or support an attachment of the magnetic slider to the flexible wiring substrate. We find that the gold ball bonding is only used to attach the signal electrodes to the respective signal terminals of the slider. We are not inclined to dispense with proof by evidence when the proposition at issue is not supported by a teaching in the prior art reference or shown to be common knowledge of unquestionable demonstration. Our reviewing court requires this evidence in order to establish a prima facie case.

Based on the evidence and arguments presented, and the pertinent law in this matter, we find that the Examiner has 8Page: Previous 1 2 3 4 5 6 7 8 9 10 NextLast modified: November 3, 2007
