Appeal No. 1998-2675 Application 08/779,024 modify Eguchi to place the microphone 3 of Eguchi in an expanded room (Br6). The Examiner responds that it would have been obvious to use an expanded room for housing the ANC device in Eguchi in order to protect the microphone under extreme conditions (EA7). As we have noted, the purpose of the enlarged room in Chaplin is to make the pressure from the driver more uniform around the microphone. There is no reason why one skilled in the art, given the teachings of Chaplin, would have sought to locate the upstream noise pickup microphone of Eguchi in an enlarged room because it is not located next to a driver. Accordingly, we conclude that the Examiner has failed to establish a prima facie case of obviousness as to independent claims 1, 10, and 11. The references to Rose, Gotoda, and Nelson, applied to the dependent claims, do not cure the deficiencies of Eguchi and Chaplin. Thus, the rejections of claims 3-5, 8, and 9 are also reversed. - 10 -Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 NextLast modified: November 3, 2007
