Appeal No. 2002-1222 Application 09/049,908 The only apparatus components required in appealed claim 25 are unspecified electric drive means that must be used with unspecified apparatus components to unwind parent rolls in steps (1), (3), (4), (7) and (8). In this respect, we find no specific definition of “electric drive means” in the specification and thus reasonably interpret this term to include any electric drive motor means that can be operatively associated with and control any apparatus component(s) that can perform the step of unwinding a parent roll, such as the apparatus components in the written description at, e.g., pages 2-7 and 12-14, and FIGs. 2 and 5, including “motors 34,” of the specification. See In re Donaldson Co., 16 F.3d 1189, 1195, 29 USPQ2d 1845, 1950 (fed. Cir. 1994) (en banc). The rolls defining a finishing unit nip can be those of, inter alia, an embossing unit as in appealed claim 26. We interpret the phrase “substantially continuous impact” to “refer to process that structurally modify the surface characteristics of the web . . . and that form a joined web for rewinding purposes when two webs from different parent rolls are processed simultaneously” in keeping with the definition that appellants provide in the written description in the specification (page 6). Appealed claim 29 modifies steps (4) and (5) of appealed claim 25 by specifying that the leading end portion of the second tissue web being unwound from the second parent roll is transported to the finishing unit using a thread-up conveyor. Appellants disclose that such an apparatus component can comprise “a vacuum means operably associated with an endless screen belt means” in the specification (page 3). The use of the open-ended term “comprising” as a transitional term and in various claim clauses opens appealed claims 25 and 29 to include methods which encompass additional steps and apparatus components. See In re Baxter, 656 F.2d 679, 686-87, 210 USPQ 795, 802-03 (CCPA 1981) (“As long as one of the monomers in the reaction is propylene, any other monomer may be present, because the term ‘comprises’ permits the inclusion of other steps, elements, or materials.”). We find that prima facie Anderson would have disclosed to one of ordinary skill in this art a continuous method of finishing a soft tissue web (e.g., col. 1, lines 39-40 and 45-46, and col. 3, lines 7-8) in an embossing nip which includes at least one splicing step, comprising at least partially unwinding a first web 1 by a drive means not illustrated in the drawings, from first parent roll 11 and transporting first web 1 to embossing nip 6 formed by rolls 13 and 14, which - 8 -Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 NextLast modified: November 3, 2007
