                 Application No. 09/782,782                                                                                                       


                         In the present case, we have reviewed the appellants' disclosure to help us                                              
                 determine the meaning of the above-noted terminology from claims 1 and 18.   That                                                
                 review has revealed that the appellants' specification provides at page 9 that the term                                          
                 "about," as used herein in connection with one or more numbers or numerical                                                      
                 ranges, should be understood to refer to all such numbers, including all numbers in a                                            
                 range.                                                                                                                           


                         However, this definition does not provide a sufficient guideline defining the                                            
                 terminology "about" as used in the claims under appeal.  For example, if this definition                                         
                 connotes that "greater than about 56" refers only to numbers greater than 56 then the                                            
                 term "about" becomes meaningless.  If this definition is meant to indicate that "greater                                         
                 than about 56" refers to all numbers greater than 56 and some numbers less than 56                                               
                 then the definition does not clearly set forth the lower limit.  Furthermore, there are no                                       
                 guidelines that would be implicit to one skilled in the art defining the term "about" as                                         
                 used in the terminology "greater than about 56 Shore D" that would enable one skilled in                                         
                 the art to ascertain what is meant by "about."  For example, one cannot ascertain if a                                           
                 Shore D hardness of 53 is "greater than about 56."  This is especially true since                                                
                 (1) dependent claim 2 further requires the outer cover layer to have a material hardness
