Office Action

§103
Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Response to Arguments Applicant’s arguments with respect to claim(s) 21 - 61 have been considered but are moot because the new ground of rejection does not rely on same interpretation of the prior art in the prior rejection of record for any teaching or matter specifically challenged in the argument. The Objection to the Drawings is overcome. The Objection to claim 22 is withdrawn. 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. Claim(s) 21 – 23, 26 – 33, 36 – 42, 45 – 49 and 58 - 61 is/are rejected under 35 U.S.C. 103 as being unpatentable over Moore (US 2012/0065638 A1). Regarding claim 21, Moore discloses a fixation device (Abstract), comprising: an elongate body (Fig. 23, ref. 102) comprising a plurality of interconnected segments (Figs. 11 – 12, ref. 12E), each of the segments comprising: an engagement member (ref. 30E, Fig. 12), a recess configured to receive the engagement member of an adjacent one of the segments (the space between the engagement member, the female to the male portions as disclosed in paragraph [0176]), and a plurality of channels (ref. 36, Fig. 12), wherein at least one of the channels extends through the engagement member (Fig. 12); and a plurality of flexible elongate members (ref. 38, Fig. 11), each extending through one of the channels (Fig. 11), wherein the elongate body is transformable between a flexible configuration in which the elongate members can move relative to one another and a rigid configuration in which the elongate members are fixed relative to one another (Abstract, paragraph [0004]). Moore is silent that the recess comprises a first portion and a second portion having a width greater than a width of the first portion. However, in a different embodiment Moore teaches a recess having a first and second portion, the second portion having a width greater a width of the first portion (see remarked Fig. 8 below, paragraph [0174]). It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the recess of Moore to include a first portion and a second portion having a width greater than a width of the first portion, as taught by the embodiment shown in Fig. 8, for the purpose of a more elaborate interlocking configuration of tabs, prongs and detents (paragraph [0174]) to better prevent unwanted loosening. PNG media_image1.png 675 593 media_image1.png Greyscale Regarding claim 22, Moore discloses the device of Claim 21, wherein the at least one of the channels is fully enclosed by at least a portion of the engagement member (Fig. 12).
