Appeal No. 2005-0986 Application No. 09/727,904 same entity. We note, again, that, unlike independent claims 1, 16, and 17, claims 18-20 do not specify the particular technique employing a blinded version of a first ciphertext portion of a signed ciphertext. Thus, while we have not sustained the rejection of claims 1- 17 under 35 U.S.C. § 103, we will sustain the rejection of claims 18-20 under 35 U.S.C. § 103 because appellants have not convincingly shown any error in the examiner’s position. The examiner’s decision is affirmed-in-part. No time period for taking any subsequent action in connection with this appeal may be extended under 37 CFR § 1.136(a)(1)(iv). AFFIRMED-IN-PART JAMES D.
