                 Appeal No.  2001-0121                                                          Page 8                    
                 Application No.  08/212,185                                                                              
                                                                                                                         
                 paragraph) point out (Brief, page 15), “as already indicated … the mutated                               
                 promoters employed by Decker et al. are not small molecules.”                                            
                         The examiner, however, finds (Answer, page 15), the term “small                                  
                 molecules” is a relative term of which there is no definition in the specification.                      
                 Accordingly, the examiner argues (Answer, bridging sentence pages 15-16), “in                            
                 the absence of any express definition, or any single generally accepted definition                       
                 in the art, … [Decker’s] promoter fragments are within the broadest reasonable                           
                 interpretation of the term ‘small molecules’ [emphasis added].”                                          
                         In our opinion, the inconsistent treatment of the term “small molecule” with                     
                 regard to the rejections under 35 U.S.C. § 112, second paragraph, and § 102(a)                           
                 has introduced substantial confusion into this record with regard to the scope of                        
                 the claim.  In this regard, we remind the examiner that analyzing claims based on                        
                 “speculation as to meaning of the terms employed and assumptions as to the                               
                 scope of such claims” is legal error.  In re Steele, 305 F.2d 859, 862, 134 USPQ                         
                 292, 295 (CCPA 1962).                                                                                    
                         Accordingly, we vacate2 the rejection of claim 100 under 35 U.S.C.                               
                 § 102(a), and remand the application to the examiner for further consideration.                          








                                                                                                                          
                 2 Lest there be any misunderstanding, the term “vacate” in this context means to set aside or to         
                 void.  When the Board vacates an examiner’s rejection, the rejection is set aside and no longer          
                 exists.  Cf. Ex parte Zambrano, 58 USPQ2d 1312, 1313 (Bd. Pat. App. & Int. 2001).
