          Appeal No. 94-3222                                                          
          Application 07/815,630                                                      
          applicants’ claims under 35 U.S.C. § 120 so as to enable one                
          to establish what constitutes the prior art under 35 U.S.C. §               
          102.                                                                        
               Moreover, while compliance with the requirements of                    
          35 U.S.C. § 112, first paragraph, is normally determined as of              
          the filing date of the pending application, the examiner, when              
          faced with an intervening reference, may be required to focus               
          on the filing date of a prior application as the result of the              
          applicants’ claims for priority under 35 U.S.C. § 120.  United              
          States Steel Corp. v. Phillips Petroleum Co., 865 F.2d 1247,                
          1251, 9 USPQ2d 1461, 1464 (Fed. Cir. 1989).  We appear to have              
          just such a case before us.                                                 
               On their face, Stolle, U.S. 5,130,128, filed November 6,               
          1989, and Beck, U.S. 4,956,349, filed April 4, 1988, appear to              
          be prior art under 35 U.S.C. § 102(e) whether or not they are               
          commonly assigned with this application filed in the names of               
          Beck and Stolle.  See In re Bartfeld, 925 F.2d 1450, 17 USPQ2d              
          1885 (Fed. Cir. 1991).  Moreover, Stolle and Beck, U.S.                     
          4,636,384 and U.S. 4,732,757 may be prior art under 35 U.S.C.               
          § 102(b).  Accordingly, faced with what prima facie appears at              
          least in part to be prior art of record and applicants’ claims              
          for priority under 35 U.S.C. § 120 in this case, the examiner               
                                          - 10 -
