Office Action

§102
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 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. Claim(s) 1 and 2 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by William J. Pivacek U.S. Patent 3,902,758 (Pivacek). Regarding claim 1, Pivacek discloses a wheelchair leg rest bracket, comprising a support rod standing on a front side of a wheelchair (Figure 1-3 Element 22 with Element 35, 39), wherein a lower part of the support rod is provided with a detachable part to achieve assembly with and disassembly from the wheelchair (Figure 4-6), an upper part of the support rod is provided with a footrest part (Element 34), and the footrest part is located in front of a leg of a user for the leg to stretch forward and rest on. Regarding claim 2, Pivacek discloses the wheelchair leg rest bracket, wherein the detachable part comprises at least one mounting beams extending outward from a side part of the support rod, and a tail end of each of the at least one mounting beam is provided with a tube clamp (Figure 1-6 Element 35 with 38). Allowable Subject Matter Claims 3-10 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
