Appeal No. 1998-0210 Application No. 08/149,193 We fully appreciate the examiner’s point of view as to each of the asserted instances of indefiniteness focused upon. However, while it is true that the language at issue is functional, it is understandable in the context used in the claim, when read in light of the underlying specification. It is important to recognize that there is nothing wrong in defining something by what it does rather than by what it is. See In re Hallman, 655 F.2d 212, 215, 210 USPQ 609, 611 (CCPA 1981). For these reasons, the language at issue is found to be definite within the meaning of 35 U.S.C. § 112, second paragraph. The third rejection We reverse the rejection of claim 134 under 35 U.S.C. § 102(b) as being anticipated by Jordan, Sr. Anticipation under 35 U.S.C. § 102(b) is established only when a single prior art reference discloses, either expressly or under principles of inherency, each and every element of a claimed invention.
