Office Action

§103
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 . Information Disclosure Statement The prior art documents submitted by applicant in the Information Disclosure Statement filed 03/19/2024 have all been considered and made of record. Joint Inventors 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. 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claims 1-32 are rejected under 35 U.S.C. 103 as being unpatentable over Grubish (US 20040256138 A1) in view of Gill (US 20230400657 A1). With regards to claim 1, Grubish discloses a duct attachment portion (Grubish/Fig4/Duct attachment portion 80) structurally configured to receive a cable, comprising: a first sub-portion (Fig5/First sub-portion 114) that is structurally configured to have a receiving portion (Fig4/Receiving portion 104; Instance of element 104 as circled below); PNG media_image1.png 443 205 media_image1.png Greyscale a second sub-portion (Fig5/Second sub-portion 112) that is structurally configured to be connected to the first sub-portion; an auxiliary wire entry portion (Fig8/Auxiliary wire entry portion as indicated within the dotted region below) that is structurally configured to receive an auxiliary wire (Fig8/Auxiliary wire 160); PNG media_image2.png 455 259 media_image2.png Greyscale an auxiliary wire entry portion seal portion that is structurally configured to be located between the first sub-portion and the second sub-portion (Fig5/Auxiliary wire entry portion seal portion 124); wherein the receiving portion is structurally configured to receive a first connector portion (Figs1&2a/First connector portion 40); wherein the second sub-portion is structurally configured to receive a second connector portion (Fig5/Second connector portion 198); wherein the auxiliary wire is associated with the cable (Figures 1, 7a, and 8/Auxiliary wire and cable both enter element 10); wherein the auxiliary wire entry portion seal portion is structurally configured to be penetrated by the auxiliary wire passing through the auxiliary wire entry portion; (Figures 5, 8, and 9) and wherein the auxiliary wire entry portion is configured to provide an entry point for the auxiliary wire separate from the receiving portion to optimize use of the attachment portion (Fig5), and the auxiliary wire entry portion is configured to improve protection of the auxiliary wire (Figs5&9/Disposition of element 124 [Grommet] with respect to elements 160 [Wire], 112 [Inside face], and 114 [Outside face]). Grubish discloses an attachment portion that is structurally configured to receive a cable, but does not specifically disclose whether or not the attachment is configured to receive a cable duct. However, the practice of linking a cable with a duct to an attachment portion exists in the art as exemplified by Gill. Grubish and Gill are considered to be analogous in the field of attachment structures for information distribution networks. Grubish discloses an attachment portion structurally configured to receive a cable. Gill teaches an attachment portion for a cable with a duct (Gill/Fig1/Attachment portion 7a; Paragraph 7/Lines 2-4). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to attach a cable with a duct to the attachment portion disclosed by Grubish as suggested by Gill, since doing so would allow for a more physically durable avenue of communication to and from the attachment portion. With regards to claim 2, Grubish and Gill together disclose the duct attachment portion of claim 1, wherein the duct attachment portion is structurally configured to be a duct port (Grubish/Fig4/Port 104 [Opening for optical cable]). Gill further teaches the duct attachment portion as being structurally configured to be a nozzle (Gill/Figs1&2/Duct port nozzle as circled below [As seen in both figures]). PNG media_image3.png 421 337 media_image3.png Greyscale PNG media_image4.png 423 250 media_image4.png Greyscale It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to configure the duct attachment portion disclosed by Grubish and Gill such that it includes a nozzle since doing so would further protect and secure the duct within the duct attachment portion. With regards to claim 3, Grubish and Gill together disclose the duct attachment portion of claim 1, wherein the first sub-portion is structurally configured to be an outer body (Grubish/Figures 1, 5, and 11 [Element 114 is directed outwardly]).

With regards to claim 5, Grubish and Gill together disclose the duct attachment portion of claim 1, wherein the duct receiving portion is structurally configured to be a port (Figs1&4/Element 104 allows for communication between interior and exterior of element 10). With regards to claim 6, Grubish and Gill together disclose the duct attachment portion of claim 1, wherein the duct receiving portion is a first duct receiving portion, and the duct attachment portion further comprises a second duct receiving portion (Fig4/Second duct receiving portion; Instance of element 104 as circled below). PNG media_image5.png 391 222 media_image5.png Greyscale With regards to claim 7, Grubish and Gill together disclose the duct attachment portion of claim 1, further comprising a sealing portion that is structurally configured to be positioned between the first sub-portion and the second sub-portion (Fig4/Sealing portion 82). With regards to claim 8, Grubish and Gill together disclose the duct attachment portion of claim 1, wherein the auxiliary wire entry portion is structurally configured to be an auxiliary wire window (Fig4/Auxiliary wire window 116). With regards to claim 9, Grubish and Gill together disclose the duct attachment portion of claim 1, wherein the auxiliary wire entry portion comprises a plurality of auxiliary wire windows (Fig4/Plurality of individual instances of element 116). With regards to claim 10, Grubish and Gill together disclose the duct attachment portion of claim 9, wherein a separate one of the auxiliary wire windows is provided for each of a plurality of the duct receiving portion (Fig4/The number of elements 116 is equal to the number of duct receiving portions 104 [4]). With regards to claim 11, Grubish and Gill together disclose the duct attachment portion of claim 1, wherein the auxiliary wire entry portion seal portion is structurally configured to be located adjacent the auxiliary wire entry portion (Fig5/Relative positions of elements 116 and 124).
