Appeal No. 2004-0189 Page 7 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 hardnessPage: Previous 1 2 3 4 5 6 7 8 9 10 11 12 NextLast modified: November 3, 2007
