Appeal No. 2002-1743 Application No. 09/047,866 this at page 10, lines 15-28. However, our perusal of that portion of Mitel tells a different story. While that portion of Mitel suggests an external microprocessor for programming registers, for affecting overall loop attenuation, user control of the speaker volume and adjustment of the positive swing of the attenuator, we find nothing therein remotely suggesting any connection of this external microprocessor/microcontroller to the first and second registers, which the examiner identifies as peak detect filters 18, such that the microprocessor/microcontroller reads values from registers in filters 18 and adjusts first and second attenuators in response to those values. In fact, looking at Figure 1 of Mitel, there appears to be no connection from either of filters 18 to any external microprocessor/microcontroller. Since the examiner does not properly address this microcontroller limitation in the response to appellants’ argument, we find that any prima facie case of obviousness that the examiner may have made has certainly been overcome by appellants’ argument. 10Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 NextLast modified: November 3, 2007
