OFFICE 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 .
DETAILED CORRESPONDENCE
This communication is a second Office Action on the Merits. Claims 10-18, as amended
03 MAR. 2025, are pending and have been considered as follows:
Allowable Subject Matter
Claim 10-18 allowed.
As allowable subject matter has been indicated, applicant's reply must either comply with all formal requirements or specifically traverse each requirement not complied with.  See 37 CFR 1.111(b) and MPEP § 707.07(a).
The following is an examiner’s statement of reasons for allowance:
Although the references of record show some similar technical features of Applicant’s claimed device, they fail to show or teach the claimed invention, wherein a prefabricated building structure comprises first and second stacked pillars and a dry-connected beam —connected without welds or casts on site— wherein the structure is defined by a novel fixing means at least partly incorporated in the first and second pillar and beam which fixing means comprises a projecting means engaging a housing means, particularly by a projecting element incorporated the first and second pillar which engaging a female housing of the beam; and further the structure comprising an enveloping means in the form of a wound fiber-resin band which compresses the pillar in an axial direction.
Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee.  Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.”
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
Calderon Uriszar-Aldaca et al.	US 10378199 B2:
The object of the present invention is a junction between columns and beams of precast reinforced concrete, with a dry joint, i.e. by means of a joint that on site does not require formwork, pouring fresh concrete, and a period for the concrete to set in order to acquire its required strength, and which makes it possible to build high-rise buildings with a competitive edge, even in seismic risk areas

APPLICANT REBUTTAL: REMARKSReconsideration and withdrawal of the rejections of the application are respectfully requested in view of the amendments and remarks herewith, which place the application in condition for allowance.I. STATUS OF THE CLAIMS AND FORMAL MATTERSClaims 10-18 are currently pending in this application. Claim 10 is independent. Claim 10 is currently amended. No new matter has been added. None of the amendments should be construed as acquiescence to any of the allegations set forth in the Office Action.II. SUPPORT FOR CLAIM AMENDMENTSNon-limiting, example support for these amendments may be found in, for example, FIG.10 and page 9 lines 8-9 of the Applicant's application.III. CLAIM OBJECTIONClaim 10 was objected to as allegedly containing informalities. Without acquiescing to any of the reasoning set forth in the Office Action, Applicant has amended Claim 10 as suggested in the Office Action to remove the alleged informalities. No new matter is added by way of these amendments. Accordingly, Applicant respectfully requests that the objection to Claim 10 be withdrawn.IV. REJECTIONS UNDER 35 USC §103 Claims 10-17 were rejected under 35 U.S.C. § 103 as allegedly being obvious in light of U.S. Patent No. 10,633,851 to Mou et al. ("Mou") and U.S. Patent No. 9,376,782 to Ehsani et al ("Ehsani"). Claim 18 was rejected under 35 U.S.C. § 103 as allegedly being obvious in light of Mou, Ehsani, and U.S. Patent No. 4,819,394 to Compton et al. ("Compton").Applicant respectfully submits that independent Claim 10, as amended, is novel over the cited references as the cited references do not teach, suggest, or disclose each and every element of independent Claim 10. In particular, Mou does not disclose at least the following features of Claim 10 "the first pillar (21), the second pillar (22) and the horizontal beam (3) are dry- connected without welds on site... casts are absent among the first pillar (21), the second pillar (22) and the horizontal beam (3)".In Mou, the introduction of pouring concrete in the joint is an essential feature. In fact, this is a feature indicated in the title and in the independent claims of this application as published (See e.g., in claim 1: "concrete filled steel tube composite joint" and in claim 8 see step VI). In the claimed invention casts are not used between the first pillar (21), the second pillar (22) and the horizontal beam (3). Indeed, independent Claim 10 states, inter alia, "the enveloping means (8) comprising a fibre-resin band which compresses the first pillar (21) along the preponderant longitudinal extension direction (20) generating an axial compression force oriented along the preponderant longitudinal extension direction". The steel tube of Mou does not comprise a fibre- resin band and consequently it does not disclose the other features associated with the fibre-resin band. Accordingly, Claim 10 is novel as the cited references do not teach, suggest, or disclose each and every element of independent Claim 10.Applicant respectfully submits that independent Claim 10 as amended, is also non-obvious over the cited references as the cited references do not teach, suggest, or disclose each and every element of independent Claim 10. Mou does not disclose at least the following features of Claim 10:the first pillar (21), the second pillar (22) and the horizontal beam (3) are dry- connected without welds on site... casts are absent among the first pillar (21), the second pillar (22) and the horizontal beam (3)" the enveloping means (8) comprising a fibre-resin band which compresses the first pillar (21) along the preponderant longitudinal extension direction (20) generating an axial compressionforce oriented along the preponderant longitudinal extension direction;As indicated in the description on page 8 lines 24-25 of the claimed invention: "[f]irstly, the nodes thus defined allow the transfer of very high specific moments without using connection casts or welds on site". None of the cited references face the objective technical problem of permitting the transfer of high specific moment in combination with high assembly speed. In particular, none of the cited references solves it as indicated in Claim 10. Ehsani discloses a fibre- resin band which compresses radially (and not axially as explicitly indicated by Claim 10) the first pillar. Nowhere does Ehsani disclose a fibre resin which compresses axially the pillar.However, the element 3 of Mou (indicated as corresponding to the first pillar of Claim 10) is a hollow tube intended to be filled by concrete; therefore, the skilled man would never have placed the fibre-resin band on the first and second base to obtain axial compression. In fact, if the bases were obstructed he would no longer be able to pour the concrete inside it (an essential characteristic of the solution described by Mou).In addition, Applicant notes that the post compression must take place on the concrete not on the metal tubular element 3; in Mou, after casting, the band is no more wrappable on the opposite bases of the tubular element 3 in order to have an axial compression; in fact the lower base of the tubular element 3 is embedded inside the component 6 and therefore becomes not accessible.Therefore, the skilled man would not have been able to combine Mou and Ehsani for obtaining the solution of Claim 10.This axial compression of the ends of the pillar is very important because in this way the post-compression load is also applied to the fixing elements. In fact, as indicated from page 8 line 31 to page 9 line 1 of Applicant's application: "the structure 1 can be incorporated with the post- compression and thereby the post-compression load is also applied to the fixing elements". So, it permits to transfer high specific moments without additional casts or welds on site. Claim 10 is therefore nonobvious. Thus, for at least the various reasons set forth above, Applicant submits that the cited references do not teach or suggest each and every element of independent Claim 10 as amended. Withdrawal of the rejections are respectfully requested.V. OTHER CLAIMSThe other claims are dependent from one of the independent claims discussed above and are patentable for at least the same reasons. Applicant, therefore, respectfully submits that the rejections herewith are overcome and request that the rejections be withdrawn. Because Applicant maintains that all claims are allowable for at least the reasons presented hereinabove, in the interests of brevity, this response does not comment on each and every comment made by the Examiner in the Office Action. This should not be taken as acquiescence of the substance of those comments, and Applicant reserves the right to address such comments.CONCLUSIONThe foregoing is submitted as a full and complete response to the Non-Final Office Action dated December 03, 2024. The foregoing amendments and remarks are believed to have placed the present application in condition for allowance, and such action is respectfully requested. The Examiner is encouraged to contact Applicant's undersigned attorney by phone at (704) 444-1078 or by email at Killian.Steer@alston.com to resolve any remaining issues in order to expedite examination of the present application.The patentability of the independent claims has been argued as set forth above and thus Applicant will not take this opportunity to argue the merits of the rejection with regard to each dependent claim. However, Applicant does not concede that the dependent claims are not independently patentable and reserves the right to argue the patentability of the dependent claims at a later date if necessary.It is not believed that extensions of time or fees for net addition of claims are required, beyond those that may otherwise be provided for in documents accompanying this paper.However, in the event that additional extensions of time are necessary to allow consideration of this paper, such extensions are hereby petitioned under 37 CFR §1.136(a), and any fee required therefore (including fees for net addition of claims) is hereby authorized to be charged to Deposit Account No. 16-0605.Respectfully submitted, /Killian K.
