Office Action

§102 §103 §DP
DETAILED ACTION This is a non-final Office Action on the merits for U.S. App. 18/339,911. Receipt of the RCE, amendments, and arguments filed on 12/12/2025 is acknowledged. Claims 20, 21, 23, 24, 27-29, 31-33, 35, 36, 41, 43-45, and 47 are pending. Claims 1-19, 22, 25, 26, 30, 34, 37-40, 42, 46, and 48-53 are cancelled. Claims 20, 21, 23, 24, 27-29, 31-33, 35, 36, 41, 43-45, and 47 are examined. Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 12/12/2025 has been entered. 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) 20, 24, 28, 32, and 44 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Wendt (U.S. Patent 4,227,355). Regarding claim 20, Wendt discloses a suspended ceiling comprising: a system for vertical suspension of an acoustic baffle, the system comprising: a frame element (#41) comprising a foldable tab (the vertical, outer tab #42 as depicted in figure 1 is the tab which is considered foldable due to the sheet metal material of such a tab (support for use of sheet metal for such a tab is found by the use of sheet metal fasteners #48 to secure thereto)) comprising a second aperture (the aperture through which fastener #48 extends through); a clip (the right clip #11 of figure 1) configured for connection to the frame element (see figure 1), wherein the clip comprises a body plate (#13), one or more fastening elements (#48/24) for securing the clip to the frame element (see figure 1), and a first aperture (#25/23), wherein the body plate comprises a cut-out (the cutout formed by punchout element #14) configured to accommodate the foldable tab of the frame element (see figures 1 and 5, where the cut-out is configured to accommodate and receive the tab of the frame element); and an acoustic baffle (#45), the acoustic baffle having two major face (the vertical outer faces of figure 1) and having minor faces (the side, top, and bottom faces of figure 1) extending between the major faces (see figure 1), wherein the acoustic baffle is supported by a frame comprising the frame element (the frame comprising of elements #41 and #43, which surround and support the baffle #45), wherein the frame element is a side profile of the frame and is attached to one of the minor faces of the acoustic baffle (see figure 1, where the frame element #41 is attached to the top, minor face of the baffle #45), and wherein the major faces of the acoustic baffle extend substantially vertically (see figures 1 and 4). Regarding claim 24, Wendt discloses the clip comprises one or more substantially planar legs (#19) joined to the body plate by an upwardly-angled joint (#20) such that the one or more substantially planar legs are parallel to the body plate (see figure 3). Regarding claim 28, Wendt discloses the body plate of the clip comprises an upper part (#13) substantially parallel to a lower part (#16), the upper part and lower part connected by a fold (#15; see figure 3). Regarding claim 32, Wendt discloses the frame comprises two frame elements, and wherein each of the two frame elements is a side profile of the frame and the two frame elements are attached to opposing minor faces of the acoustic baffle (See figures 1 and 4, where the two frame elements can be considered the left and right side profiles #41, that can be attached to one another using the same clip #11. Alternatively, the frame elements can be considered elements #41 and #43 of the same baffle #45 with comprises of the same structure with a foldable tab and aperture, where the claims do not positively define that the cutout portion of the clip need to positively engage the tab of the second frame element.). Regarding claim 44, Wendt discloses wherein the clip comprises one or more legs (#19) joined to the body plate by an upwardly angled joint (#20) such that the one or more legs are parallel to the body plate (see figure 3), wherein the body plate of the clip comprises an upper part (#13) substantially parallel to a lower part (#16), the upper and the lower part connected by a fold (#15; see figure 3). Claim Rejections - 35 USC § 103 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) 23, 27, 31, 35, and 47 are rejected under 35 U.S.C. 103 as being unpatentable over Wendt in view of Bergman (U.S. Publication 2012/0291397). Regarding claim 23, Wendt discloses a system for vertical suspension of an acoustic baffle, the system comprising: a frame element (#41); a clip (#11) configured for connection to the frame element (see figure 1), wherein the clip comprises a body plate (#13) and a first aperture (the aperture through which fastener #48/24 extends); a beam hanger (#51) configured for connection to the clip (see figure 5), wherein the beam hanger comprises a substantially rectangular first plate (see figures 4 and 5); and an acoustic baffle (#45), the acoustic baffle having two major faces (the vertical outer faces of figure 1) and having minor faces (the side, top, and bottom faces of figure 1) extending between the major faces (see figure 1), wherein the acoustic baffle is supported by a frame comprising the frame element (the frame comprising of elements #41 and #43, which surround and support the baffle #45), wherein the frame element is a side profile of the frame and is attached to one of the minor faces of the acoustic baffle (see figure 1, where the frame element #41 is attached to the top, minor face of the baffle #45), and wherein the major faces of the acoustic baffle extend substantially vertically (see figures 1 and 4). However, Wendt does not disclose the beam hanger comprises of a second plate and a third plate such that the second plate and the third plate are substantially parallel and face each other and the first plate is connected at opposing edges to such second and third plates. Wendt does disclose that such hangers #51 can desirably be subpurlins or other substructures depending from an upper ceiling. See col. 8, ll. 51-57. It is highly well known in the art, as evidenced by Bergman, that such beam hangers can comprise of I-beam hangers formed from a central, first plate #38 between parallel second #40/42 and third (the plate at the bottom of slot #32 of figure 6) plates such that a clip #10 can still be fastened to the first plate thereof. See figure 6. Therefore, it would have been obvious before the effective filing date of the claimed invention to have constructed the beam hanger of Wendt to comprise of a first plate with parallel second and third plates at opposite edges thereof, as taught in Bergman, in order to allow the assembly to attach to different ceiling supports as needed by the end user and provide a stronger beam hanger. Regarding claim 27, Wendt in view of Bergman render obvious the clip comprises one or more substantially planar legs (Wendt; #19) joined to the body plate by an upwardly-angled joint (Wendt; #20) such that the one or more substantially planar legs are parallel to the body plate (see figure 3 of Wendt). Regarding claim 31, Wendt in view of Bergman render obvious the body plate of the clip comprises an upper part (Wendt; #13) substantially parallel to a lower part (Wendt; #16), the upper part and the lower part connected by a fold (Wendt; #15). Regarding claim 35, Wendt in view of Bergman render obvious the frame comprises two frame elements, and wherein each of the two frame elements is a side profile of the frame and the two frame elements are attached to opposing minor faces of the acoustic baffle (See figures 1 and 4 of Wendt, where the two frame elements can be considered the left and right side profiles #41, that can be attached to one another using the same clip #11. Alternatively, the frame elements can be considered elements #41 and #43 of the same baffle #45 with comprises of the same structure with a foldable tab and aperture, where the claims do not positively define that the cutout portion of the clip need to positively engage the tab of the second frame element.). Regarding claim 47, Wendt in view of Bergman render obvious wherein the clip comprises one or more fastening elements (Wendt; #48/24) for securing the clip to the frame element (see figure 1 of Wendt), wherein the clip comprises one or more legs (Wendt; #19) joined to the body plate by an upwardly angled joint (Wendt; #20) such that the one or more legs are parallel to the body plate (see figure 3 of Wendt), wherein the body plate of the clip comprises an upper part (Wendt; #13) substantially parallel to a lower part (Wendt; #16), the upper and the lower part connected by a fold (Wendt; #15). Claim(s) 23, 35, and 36 are rejected under 35 U.S.C. 103 as being unpatentable over Wendt ‘644 (U.S. Patent 4,031,664) in view of Langeveld (U.S. Publication 2018/0127984). Regarding claim 23, Wendt ‘644 discloses a system for vertical suspension of an acoustic baffle, the system comprising: a frame element (#33); a clip (#22) configured for connection to the frame element (see figure 1), wherein the clip comprises a body plate (#22) and a first aperture (#28); a beam hanger (#37) configured for connection to the clip (see figure 5); and an acoustic baffle (#29), the acoustic baffle having two major faces (the vertical outer faces of figure 1) and having minor faces (the side, top, and bottom faces of figure 1) extending between the major faces (see figure 1), wherein the acoustic baffle is supported by a frame comprising the frame element (the frame comprising of elements #33, which surround and support the baffle #29), wherein the frame element is a side profile of the frame and is attached to one of the minor faces of the acoustic baffle (see figure 1, where the frame element #33 is attached to the side, minor face of the baffle #45), and wherein the major faces of the acoustic baffle extend substantially vertically (see figures 1 and 45). However, Wendt ‘644 does not disclose the beam hanger comprises of first, second, and third plates such that the second plate and the third plate are substantially parallel and face each other and the first plate is connected at opposing edges to such second and third plates. It is highly well known in the art, as evidenced by Langeveld, that such beam hangers #11 can comprise of a first plate #15, with second #18 and third #18 plates extending upwardly from opposing ends of the first plate, where the second and third plates comprising of hinged tabs #14 in order to attach the beam hanger to a C-shaped channel #30 that supports the ceiling assembly. See figure 12b. Langeveld discloses the beam hanger #11 first plate #15 can comprise of an aperture for receiving a fastener #42 to attach the beam hanger to a U-shaped clip #41 extending therebelow that is configured to attach to a vertical baffle #38. See figure 15. Therefore, it would have been obvious before the effective filing date of the claimed invention to have constructed the beam hanger of Wendt ‘644 to comprise of a first plate with parallel second and third plates extending upwardly at opposite edges thereof, as taught in Langeveld, in order to allow the assembly to attach to an upper U-shaped support channel in a quicker manner. Regarding claim 35, Wendt ‘644 in view of Langeveld render obvious the frame comprises two frame elements, and wherein each of the two frame elements is a side profile of the frame and the two frame elements are attached to opposing minor faces of the acoustic baffle (See figures 1 and 5 of Wendt ‘644, where the two frame elements can be considered the left and right side profiles #33, that can be attached to one another using the same clip #22.). Regarding claim 36, Wendt ‘644 in view of Langeveld render obvious each of the second plate and the third plate each comprise a hinged tab (Langeveld; #14) configured for connection to a C-profile beam (see figure 15 of Langeveld, where such features would be provided within Wendt ‘644 as explained above). Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13. The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission.
