Appeal No. 1999-2242 Application No. 08/137,056 We find the appellant's argument unpersuasive for the following reason. The appellant's argument is not based upon the rejection before us. Claim 12 has been rejected based on the combined teachings of Yasukawa, Church and Mohiuddin. The appellant has argued that claim 12 is not rendered obvious from the individual teachings of Church and Mohiuddin. The appellant has not provided any argument as to why the rejection under 35 U.S.C. § 103 before us in this appeal based upon the combined teachings of Yasukawa, Church and Mohiuddin is in error. Nonobviousness cannot be established by attacking the references individually when the rejection is predicated upon a combination of prior art disclosures. See In re Merck & Co., Inc., 800 F.2d 1091, 1097, 231 USPQ 375, 380 (Fed. Cir. 1986). For the reasons set forth above, we will sustain the examiner’s rejection of claims 12 through 14 under 35 U.S.C. § 103(a) as being unpatentable over Yasukawa in view of Church and Mohiuddin.
