Based on the totality of the record, including due consideration of Appellants’ arguments, we determine that the preponderance of evidence weighs most heavily in favor of obviousness within the meaning of § 103(a). Therefore we affirm all rejections on appeal based on § 103(a). C. Summary We have affirmed all rejections on appeal. Therefore the decision of the Examiner is affirmed.
