                 Appeal No. 1998-2587                                                                                     
                 Application No. 08/451,993                                                                               

                 enable them.  The examiner therefore argues that both Terasawa EP and Mitsui                             
                 are available as prior art.                                                                              
                         We agree with the examiner that a claim must be enabled by a priority                            
                 document in order to gain the benefit of an earlier effective filing date under 35                       
                 U.S.C. § 120.  See In re Hogan, 559 F.2d 595, 604, 194 USPQ 527, 536 (CCPA                               
                 1977) (“[S]ymmetry in the law, and evenness of its application, require that § 120                       
                 be held applicable to all bases for rejection, that its words ‘same effect’ be given                     
                 their full meaning and intent.”)  Accord, Transco Prods. Inc. v. Performance                             
                 Contracting Inc., 38 F.3d 551, 557, 32 USPQ2d 1077, 1082 (Fed. Cir. 1994)                                
                 (§ 120 requires compliance with all the requirements of the first paragraph of                           
                 § 112).  Therefore, we reject Appellants’ argument that they “are entitled to the                        
                 filing date of January 14, 1992 pursuant to 35 U.S.C. §  120, regardless of the                          
                 sufficiency of disclosure.”  Appeal Brief, page 5 (emphasis in original).                                
                         However, we have already concluded that the instant claims are enabled                           
                 by the instant specification.  See pages 3 to 6, supra.  The examiner has not                            
                 suggested that the degree of enablement provided by the parent applications                              
                 differs from that of the instant application; the disclosures are apparently                             
                 identical.  Therefore, the claims were apparently enabled by the parent                                  
                 specifications and are therefore entitled to the benefit of priority under § 120.                        
                 The effective filing date of the instant claims is January 14, 1992.  Neither                            
                 Terasawa EP nor Mitsui are prior art, so neither can form the basis of a rejection                       
                 under 35 U.S.C. §  102.                                                                                  


                                                            7
