Appeal No. 1997-2856
Application 08/394,251
Claims 12-14, 16, and 17
Appellant argues that the Examiner's finding that
"Skwirut lacks the electronic high frequency ballast being a
half-bridge type" (FR9) is not understood since no such
ballast is being claimed (Br11). The Examiner responds that
"[t]he half-bridge forms the basis of Appellant's invention"
(EA16).
We agree with Appellant that the Examiner's action should
address claimed differences. The limitations of the claims do
not appear to be inherent characteristic features of a high
frequency ballast of a half-bridge type.
With respect to claim 12, the Examiner found that "[t]he
ballast of Dale clearly conducts current pulses through the
transistor at a frequency equal to the output frequency and
whose duration is less that 1/2 the period of the output"
(FR9). Appellant argues that the feature of claim 12 is not
disclosed by Dale as the Examiner contends. The Examiner
responds that the feature of the current pulses being less
than 1/2 the period of the output "occurs in the ballast
structure of Dale" (EA16).
