Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claim 18 is rejected under 35 U.S.C. 103 as being unpatentable over Reed, in view of Schmauder (US 2007/0101840), hereafter Schmauder. Regarding Claim 18, Reed discloses a machining device for cutting flat material (Col 1, Ln 8-28, especially Ln 27-28), comprising: a cutting device arrangement (A) (Col 1, Ln 17; as illustrated in at least Fig 1) configured to cut the flat material (Col 1, Ln 15, 17-19), comprising: a radially outer cutting edge area (98) having at least one arcuate cutting edge (100) (Col 4, Ln 63-65 & Col 5, Ln 1-2; as illustrated in at least Fig 1); an attachment arrangement for attachment to the machining device (32) (34) (Col 3, Ln 41, 43, resp.; as illustrated in at least Fig 2); a first coupling arrangement having a first coupling portion (120) (Col 6, Ln 45; as illustrated in at least Fig 6); and a second coupling arrangement having a second coupling portion (122) (Col 6, Ln 47-48; as illustrated in at least Fig 6), wherein the cutting device arrangement defines a circumferential direction in accordance with an arcuate shape of the cutting device arrangement (as illustrated in at least Fig 1), and wherein at least one of the first and the second coupling arrangements are configured to be releasably coupled to another cutting device arrangement in the circumferential direction (Col 6, Ln 41-47; as illustrated in at least Fig 6). Examiner notes it is well known in the art to releasably connect elements using screws. Reed is silent to a base having a support table configured for a flat material the base defining a feed direction in which the flat material can be fed into the machining device. Schmauder teaches a machining device for cutting flat material (Para [0002], Ln 1-3). Schmauder further teaches a base (4) including a support table (10) for the flat material, the base defining a feed direction in which the flat material can be fed into the machining device (al as illustrated in at least Fig 1). Examiner notes that a skilled Artisan would recognize the space between the cutter (6) and the table (10) as defining a workpiece feed direction, into the machine. It would therefore have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the machining device for cutting flat material, as disclosed by Reed, to include a base having a support table configured for a flat material the base defining a feed direction in which the flat material can be fed into the machining device, as taught by Schmauder, in order to process the material. Claim 19 is rejected under 35 U.S.C. 103 as being unpatentable over Reed, in view of Schmauder and Laib, et alia (WO 2008 046500),hereinafter Laib. Regarding Claim 19, combined Reed/Schmauder teaches all aspects of the claimed invention, as stated above. Reed further discloses, wherein the machining device further comprises a second cutting device arrangement comprising a second cutting device (Col 1,Ln 23-28, especially Ln 27-28). Reed is not explicit to the second cutting device arrangement defines a second circumferential direction in accordance with a second arcuate shape of the second cutting device arrangement, and wherein the second cutting device arrangement comprises: a second radially outer cutting edge area having at least one second arcuate cutting edge; a second attachment arrangement for attachment to the machining device; and at least one coupling arrangement configured to be releasably coupled the first cutting device arrangement. Examiner notes a skilled Artisan would recognize the utility of replicating like devices for like purposes, as disclosed by Reed. It would therefore have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the machining device for cutting flat material, as taught by combined Reed/Schmauder, to include the second cutting device arrangement defines a second circumferential direction in accordance with a second arcuate shape of the second cutting device arrangement, and wherein the second cutting device arrangement comprises: a second radially outer cutting edge area having at least one second arcuate cutting edge; a second attachment arrangement for attachment to the machining device; and at least one coupling arrangement configured to be releasably coupled the first cutting device arrangement, as is well known in the art, to maximize the efficiency of utilizing like parts for like purposes. Reed is silent to the cutting device arrangement comprises a first cutting device configured to cut the flat material in the feed direction. Laib teaches first cutting device configured to cut the flat material in the feed direction (page 3, machine translation provided herein, Para [Description] Ln 2-3), as well as a first cutting device configured to cut the flat material transversely to the feed direction (page 3, machine translation provided herein, Para [Description] Ln 8-10). Laib further teaches the advantage of this arrangement in that it allows for more efficient utilization of the machine (page 4, machine translation provided herein, Para [Description] Ln 11-13). It would therefore have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the machining device for cutting flat material, as taught by combined Reed/Schmauder, to include first cutting device configured to cut the flat material in the feed direction, as well as a first cutting device configured to cut the flat material transversely to the feed direction, as taught by Laib, in order to provide for more efficient utilization of the machine. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. US 1,584,868 to Kutter teaches a machining device for cutting flat material.
