In regards to Claim 17, Getz as modified discloses the riser assembly (100) [Abstract] [Figs 1-20] as claimed in claim 1 However, fails to disclose wherein at least one frame member is incorporated in a slip-formed wall which forms a part of the boundary of the riser aperture. Furthermore, Wook discloses wherein at least one frame member (Unnumbered, Figs 1-2, Getz] (see examiners comment) is incorporated in a slip-formed wall [Background, Paragraph 1] which forms a part of the boundary of the riser aperture [Unnumbered, Fig 1, Getz] (see examiners comment). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the riser assembly as disclosed by Getz include at least one frame member is incorporated in a slip-formed wall which forms a part of the boundary of the riser aperture as disclosed by Wook. When modified, it allows for construction purposes as intended for apertures between different floors. 5. Claims 22 and 26 are rejected under 35 U.S.C. 103 as being unpatentable over Getz (US 20180266100 A1) in view of Robert Ian Dobson (GB 2256211 A)(Herein Dobson) and Park Nam Wook (KR 20090043029) (Herein Wook). In regards to Claim 22, Getz as modified discloses the method [0005, 0007] as claimed in claim 19. Wook discloses wherein at least one frame member (Unnumbered, Figs 1-2, Getz] (see examiners comment) is formed in a slip-formed wall [Background, Paragraph 1], which forms a part of the boundary of the riser aperture [Unnumbered, Fig 1, Getz] (see examiners comment). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the method as disclosed by Getz to include wherein at least one frame member is formed in a slip-formed wall, which forms a part of the boundary of the riser aperture as disclosed by Wook. When modified, the slip-formed wall with all the limitations recited allows for the method/riser to be used for multiple different scenarios (i.e., high rises, multiple floors, hotels, building) In regards to Claim 26, Getz as modified discloses The method [0005, 0007] as claimed in claim 19, including constructing a wall [Background, Paragraph 1, Wook] above the joist (106) [Figs 1 and 7], wherein the joist (106) [Figs 1 and 7] and the wall [Background, Paragraph 1, Wook] are at least partially in the same vertical plane [As modified] and wherein the joist (106) [Figs 1 and 7] supports the wall [Background, Paragraph 1, Wook]. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the riser assembly as disclosed by Getz to include constructing a wall above the joist as disclosed by Wook. When modified, this allows for constructability of the riser assembly and frame to be used within different floors. Claim 25 is rejected under 35 U.S.C. 103 as being unpatentable over Getz (US 20180266100 A1) in view of Robert Ian Dobson (GB 2256211 A)(Herein Dobson) and Wunsch Horst (EP 2735794) (Herein Horst) In regards to Claim 25, Getz as modified discloses the method [0005, 0007] as claimed in claim 19, including supporting a service conduit [See Horst, Page 4, Fig 1 Description] passing through the riser aperture [Unnumbered, Fig 1] (see examiners comment) with a bracket (33, Horst) [Fig 1] which connects into the channel [Unnumbered, Figs 1-2] (see examiners comments) and is slidable therein. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify a riser as disclosed by Getz to include the bracket supporting a service conduit passing through the aperture, wherein the bracket connects into the channel as disclosed by Horst. When modified, the bracket with all limitations allows for securing passages for the service conduits, facilitating connection to the channel, in lieu of a person of ordinary skill in the art having to core the settable material post installation. Allowable Subject Matter 6. Claim 18, 23-24, 30 would be allowable if rewritten to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action and to include all of the limitations of the base claim and any intervening claims. The following is a statement of reasons for the indication of allowable subject matter: In regards to Claim 18, the prior art of record fails to teach the totality of the invention, in combination with the additionally claimed elements, including a bracket supporting a service conduit passing through the riser aperture wherein the bracket connects into the channel of the frame member supported on the slip-formed wall.
