          Appeal No. 1997-3497                                       Page 6           
          Application No. 08/312,295                                                  

          § 1.192(c)(7) and (c)(8)(iv)(1995).  In this regard, we note that           
          merely pointing out the features of the various dependent claims            
          does not serve to explain in detail why each such claim is                  
          separately patentable over the prior art as applied by the                  
          examiner under § 103.  Accordingly, we consider the dependent               
          claims 2, 4-7, 10, 11, 13, 14, 16-24 to stand or fall with                  
          independent claim 1, on this record.  See In re Nielson, 816 F.2d           
          1567, 1571, 2 USPQ2d 1525, 1527 (Fed. Cir. 1987).  In any event,            
          even if separate consideration of the dependent claims for which            
          separate groupings have been identified was warranted on this               
          record, we note that a sufficient explanation of the rejections             
          of the appealed claims is found in the examiner's answer to                 
          refute appellants' position as set forth in the brief relative to           
          those separately grouped dependent claims as well as to refute              
          appellants' position regarding independent claim 1 and separately           
          argued independent claim 28.                                                
               Like appellants, Shiga discloses a biaxially oriented                  
          polypropylene film structure.  The examiner has found that Shiga            
          uses a highly isotactic polypropylene that corresponds to the               
          polypropylene of appellants’ claim 1 (answer, page 4, lines 2-6).           
          Appellants do not specifically dispute that finding of the                  
          examiner.  As also found by the examiner (answer, pages 3 and 4),
