DETAILED ACTION 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 . Claim Rejections - 35 USC § 102 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 the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.

Regarding claim 9, the bolt head at 15 is dimensioned and configured to pass through the opening formed by the aligned first and second slots in a first orientation (figure 18) and is dimensioned and configured to prevent withdrawal of the bolt head back through the opening formed by the aligned first and second slots in a second orientation in which the T-bolt is rotated as compared to the first orientation (figure 17). Regarding claim 10, the bolt head collar portion 12 includes a front end, a rear end, a first side, and a second side (figures 17 and 18), the first side and the second side each including a rounded portion dimensioned and configured to assist in rotation in the opening formed by the aligned first and second slots from the first orientation to the second orientation and a planar portion dimensioned and configured to abut opposing interior walls of the aligned first and second slots in the second orientation (figure 7). Regarding claim 11, the interior end of the washer base portion includes a plurality of teeth (9 in figure 33) for enhancing the engagement to the outer surface of the second joining member. Regarding claim 12, the bolt head collar portion 12 is dimensioned and configured such that, when the fastening system 1 is in the installed position (figure 6), the bolt head collar portion extends through the first slot and partially into the second slot (figure 6).
