Appeal No. 98-2109 Application No. 08/500,315 id. ), or a manner or method of using the claimed machine "which is not germane to the issue of patentability of the machine itself" (Casey, id.). Rather, the limitation is in the nature of a structural limitation, in that it effectively requires a cutting element which is capable of emitting a liquid-jet stream when in the idle position; otherwise, there would be no stream for the disk to deflect. Driver does not disclose a cutting element which can operate in such a manner, and therefore does not anticipate claim 1. We note in this regard that "[t]here is nothing intrinsically wrong in defining something by what is does rather than by what it is." In re Echerd, 471, F.2d 632, 635, 176 USPQ 321, 322 (CCPA 1973). Accordingly, the rejection of claim 1, and therefore of claims 2, 3, 5 and 9 to 11 dependent thereon, will not be sustained. Conclusion The examiner’s decision to reject claims 1 to 3, 5 and 9 to 11 is reversed. 7Page: Previous 1 2 3 4 5 6 7 8 9 NextLast modified: November 3, 2007
