Appeal No. 96-1904 Application 08/164,854 597, 600 (CCPA 1971). In the present case, we conclude that the content of claims 20 and 21 can be reasonably understood, not- withstanding the breadth thereof. Since the metes and bounds of the claimed subject matter are ascertainable, the claims are not indefinite. The rejection under 35 U.S.C. § 102(b) We reverse the rejection of claim 1, but affirm the rejection of claim 20. The segmented computer keyboard of claim 1 requires, inter alia, a left and right hand keyboard that may be operated “independently of supporting surfaces.” Following our analysis of claim 1, supra, this quoted recitation is taken to mean that the operation of the keyboard is carried out independent of supporting structural surfaces. In other words, the language clearly infers operation of the keyboard while only being supported by a user. 11Page: Previous 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 NextLast modified: November 3, 2007
