Appeal No. 95-3919 Application No. 07/907,934 The obviousness rejection of claim 134 is reversed because Katznelson does not count requests for a product in order to compute an amount to be billed for use of a product on CD-ROM. The obviousness rejection of claim 135 is sustained because the terminal 10 in Katznelson obtains the address/unit ID of terminal 11, without any input from terminal 11, when the encrypted file key 13 and the authenticated credit data 14 are sent to terminal 11. The obviousness rejection of claim 136 is reversed because terminal 11 in Katznelson does not resend a request if a reply is not received from terminal 10 “within a predetermined period of time after” the request is sent. 9Page: Previous 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 NextLast modified: November 3, 2007
