                 Appeal 2007-0870                                                                                      
                 Reissue Application 09/902,904                                                                        
                 Patent 6,038,784                                                                                      
                        1. Is claim 2 indefinite under § 112, second paragraph?                                        
                        Claim 2 recites an apparatus comprising, in relevant part, "a tray                             
                 having a bottom face that is adapted to be supported by an underlying                                 
                 surface such as a counter-top. . .".  The issue is whether use of exemplary                           
                 claim language ("such as") renders claim 2 indefinite under 35 U.S.C. § 112,                          
                 paragraph 2.                                                                                          
                        Appellants' Specification describes a tray having a bottom face that is                        
                 adapted to be supported by an underlying surface such as a counter-top (col.                          
                 2, ll. 1-3, and 56-58).  Descriptions of examples or preferences, e.g., a                             
                 counter-top as a preferred underlying surface, are properly set forth in the                          
                 Specification rather than in the claims because stating examples or                                   
                 preferences in the claims may lead to confusion over the intended scope of                            
                 the claim.  Here, the phrase "such as" in claim 2 is indefinite because it is                         
                 unclear from Appellants' Specification whether the tray bottom encompasses                            
                 is adapted to be supported by both (a) a flat working surface, e.g., in the case                      
                 of a counter-top, or (b) a non-flat working surface, e.g., a ridged/channeled                         
                 drain board or a wire basket drain rack.  A tray adapted to be supported on a                         
                 non-flat underlying surface might well have a complementary ridged bottom                             
                 surface to control undesirable tray movement on the underlying surface.                               
                 This claim language is analogous to the "material such as a rock wool or                              
                 asbestos" language that was found to be indefinite in Ex parte Hall, 83                               
                 USPQ 38, 39 (Bd. App. 1949) ("it is not clear whether the material is                                 
                 actually rock wool or asbestos or some other material which for some                                  
                 unexplained reason in the claim is like one or the other of these materials.").                       
                 Thus, it is unclear whether "such as" is intended to more narrowly define the                         


                                                          10
