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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claims 17-24 are rejected under 35 U.S.C. 103 as being unpatentable over Shusaku et al. ‘336 in view of U.S. Patent No. 9,254,234 to Cooper et al. With respect to claims 17 and 19-24, Shusaku et al. do not specifically disclose conditions wherein the base (108) comprises a first support surface, wherein the apparatus (100) is dockable relative to a second support surface; wherein the primary member (103) is moveable between a proximal side and a distal side of the base (108), relative to the second support surface; wherein the primary member is coupled to a track extending between the proximal side and the distal side of the base; wherein the coupling end of the primary member (103) is slidably coupled to the base (108) to move along a width of the base, wherein a movement in the primary member is supported by at least one support arm in a support position; wherein the at least one support arm is pivotably coupled to the base (108) to move between a folded position and the support position, relative to the base; wherein the apparatus (100) is actuatable between an operating state and a folded state, wherein in the folded state, the interface member (102) is disposed at a back of the base (108); and wherein the base comprises a wheelchair. Cooper et al. ‘234 provides the basic teaching of a patient assist apparatus comprising an electric powered wheelchair base (8) comprising a first support surface (11), wherein the apparatus is dockable relative to a second support surface (30) (as shown in Figures 1 & 6 and as described in column 5, lines 53-57 and in column 7, lines 29-46); a primary member (14-16) which is moveable between a proximal side and a distal side of the base (8) via a track (9) extending between the proximal side and the distal side of the base, wherein a coupling end of the primary member (14-16) (i.e., a bottom end of the primary member) is slidably coupled to the base (8) to move along a width of the base (via element 9) (as shown in Figures 1, 2 & 6 and as described in column 6, lines 36-43); at least one support arm (17) which supports a movement in the primary member (14-16) in a support position, wherein the at least one support arm is pivotably coupled to the base (8) to move between a folded position (as shown in Figure 2) and the support position (as shown in Figure 1) relative to the base (8) (also as described in column 6, lines 47-49 and in column 7, lines 2-15); and an interface member (18-20) coupled (via element 17) to the primary member (14-16), wherein the apparatus further is actuatable between an operating state (as shown in Figure 1) and a folded state (as shown in Figure 2), and wherein in the folded state, the interface member (18-20) is disposed at a back of the base (8) (via track 9) (also as described in column 6, lines 36-43). The skilled artisan would have found it obvious before the effective filing date of the claimed invention to combine the apparatus disclosed in Shusaku et al. with the primary member, the at least one support arm, the interface member and the wheelchair base taught in Cooper et al. ‘234 with a reasonable expectation of success because this would have achieved the desirable result of facilitating transfer of a patient between first and second support surfaces as taught by Cooper et al. ‘234 (column 5, lines 53-57 and column 7, lines 31-34). With respect to claim 18, Shusaku et al. further disclose a condition wherein the primary member (103) is constrained to a translation displacement along a path (via elements 120) (as shown in Figures 13-19 and as described on page 20, in paragraph 0091). Allowable Subject Matter Claims 8 and 15 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. The examiner respectfully asserts that one of ordinary skill in the art would not have found it obvious before the effective filing date of the claimed invention to modify the respective patient assist apparatuses of Wang ‘748 and Shusaku et al. ‘336 to include the particular operational arrangements between the three or more attachment members and the interface member as recited in dependent claim 8, and between the controller, the attachment elements and the at least one sensor as recited in dependent claim 15. Conclusion The prior art made of record and not relied upon is considered pertinent to Applicant's disclosure: Ang et al. ‘558, Wang ‘063, Cooper et al. ‘981, Wang ‘708, Fernie et al. ‘285, Wang ‘398, Ang et al. ‘020 and Tomoyuki et al. ‘276.
