              Application No. 09/632,160                                                                                  


                                                    BACKGROUND                                                            
                     The appellants' invention relates to a low cost optical fiber cable in which                         
              an optical fiber core having an outer covering is suppressed from movement inside the                       
              outer covering in the lengthwise direction thereof and which does not cause                                 
              deterioration of the transmission characteristics even when the cable is bent, and to a                     
              method of producing the same (specification, p. 1).  A copy of the claims under appeal                      
              is set forth in the appendix to the appellants' brief.                                                      


                     The prior art references of record relied upon by the examiner in rejecting the                      
              appealed claims are:                                                                                        
              Hager et al. (Hager)                5,016,973                           May 21, 1991                        
              Keller et al. (Keller)              6,253,012                           June 26, 2001                       



                     Claims 1 to 8 stand rejected under 35 U.S.C. § 103 as being unpatentable over                        
              Hager in view of Keller.                                                                                    


                     Rather than reiterate the conflicting viewpoints advanced by the examiner and                        
              the appellants regarding the above-noted rejection, we make reference to the answer                         
              (Paper No. 12, mailed February 12, 2003) for the examiner's complete reasoning in
