                         In rejecting claims under 35 U.S.C. § 103, it is incumbent upon the examiner to                                           
                 establish a factual basis to support the legal conclusion of obviousness.  See In re Fine,

                 stem from some teachings, suggestions or implications in the prior art as a whole or
