Appeal No. 2001-0950 Application No. 08/534,855 communication stream. Upon review, we sustain the rejection of claim 26. For claim 27, Appellants argue that the references do not teach or suggest the requirement that "the BER is determined by comparing known bits of TEI overhead messages with received bits of TEI overhead messages." See Appeal Brief, Page 14, lines 12- 13. Upon review, we fail to find any evidence that Stengel teaches or suggests the use of known bits of TEI overhead messages. In conclusion, we sustain the rejection of claims 1, 19, 29, and 31 under 35 U.S.C. § 102(b) and claims 25 and 26 under 35 U.S.C. § 103. We cannot sustain the rejection of claims 3, 21, 28 30 under 35 U.S.C. § 102(b) and 2, 4-18, 20, 22-24, and 27 under 35 U.S.C. § 103 . 12Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 NextLast modified: November 3, 2007
