Appeal No. 1998-2295 Application No. 08/435,902 and 12. The addition of the Blackburn reference also does not remedy the deficiency in the teachings of Quets. We therefore reverse the rejection of claims 9, 10, 11, 12, 13 and 15 to 20. We note the Examiner has taken official notice regarding several features of the claimed invention throughout the prosecution of this application. The Examiner has refused to provide evidence of the various embodiments of the claimed invention even thought the Appellants have seasonably requested the Examiner provide this information. (See MPEP § 2144.03). Once Appellants have seasonably and adequately challenged the facts alleged to be common knowledge, the burden of proof in on the Examiner to provide evidence to support his findings. Cf. In re Lee, 277 F3d 1338, 1342-43, 61 USPQ2d 1430, 1433 (Fed. Cir. 2002). CONCLUSION The rejection of claims 1, 3, 4, 7 and 8 under 35 U.S.C. § 103(a) as obvious over the combination of Wolfla and Hodshire is affirmed. The 35 U.S.C. § 103(a) rejections of claims 2, 6, 9, 10, 11, 12, 13 and 15 to 20 are reversed. -8-Page: Previous 1 2 3 4 5 6 7 8 9 10 NextLast modified: November 3, 2007
