                 Appeal 2007-2864                                                                                      
                 Application 10/747,798                                                                                
                 examination is to fashion claims that are precise, clear, correct, and                                
                 unambiguous. Only in this way can uncertainties of claim scope be removed,                            
                 as much as possible, during the administrative process.”  In re Zletz, 893                            
                 F.2d 319, 322 (Fed. Cir. 1989).                                                                       
                        The Examiner cites Hay (first sheet); Lowe (first sheet); and "What is                         
                 a Dermatologist?” (third sheet), to support the interpretation of skin as                             
                 including the mucosa of the mouth and cervix (Answer 12).  Appellant                                  
                 responds that the Specification supports a plain and ordinary meaning of                              
                 skin distinct from mucosa.  For example, Appellant cites page 3, lines 25-26,                         
                 which teaches that the “cell can be a keratinocyte, an epithelial cell, a skin                        
                 cell, a mucosal cell, or any other cell that can undergo transformation by a                          
                 papillomavirus.”  That teaching from the Specification, however, does not                             
                 support Appellant’s assertion that the cells are mutually exclusive.  For                             
                 example, an epithelial cell may also be a skin cell.3  Thus, we find that the                         
                 preponderance of the evidence supports the Examiner’s proffered                                       
                 interpretation of the term “skin,” and the rejection of claim 6 is affirmed.                          
                        As to claim 18, 33, and 54, Appellant argues that Clayman cannot                               
                 anticipate these claims as there is no express or inherent disclosure of the                          
                 claimed “douche solution.”  (Br. 8.)  Appellant also asserts that contrary to                         
                 the Examiner’s argument that a douche is simply a jet of liquid, “there is no                         
                 disclosure in Clayman pertaining to any jet of liquid applied to any part of                          
                 the body, vagina or otherwise.”  (Id. (emphasis in original).)                                        
                                                                                                                      
               3  The American Heritage Science Dictionary defines the epithelium as lining                            
                 the outer layer of the skin (epidermis), as well as the surface of most body                          
                 cavities.  (epithelial, Dictionary.com. The American HeritageŽ Science
