Office Action

§112
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 . This Office Action is in response to the Amendment dated January 16, 2026. Currently, claims 1-19 are pending in the application. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 1-19 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Regarding claim 1: It is unclear how the plurality of base units differ from the plurality of semi-units. The semi-units appear to be the plurality of base units in the final assembled arrangement. Additionally it is unclear how the main unit differs from the semi-units or the plurality of base units as it appears it is the final assembly of semi-units which is the final assembly of base units. Regarding claim 2: It is unclear if the support bracket and exterior wall frame are intended to be positively recited. The claim indicates the fixing bracket is “configured to be seated on a support bracket…” but does not positively claim the bracket and frame. However, the claim further indicates the fixing bracket is secured to the support bracket. It is assumed that the support bracket and wall frame are intended to be positively recited and will be examined accordingly. It I suggested that language that reflects the positively claimed support bracket and will frame be added in order to clarify. Regarding claims 8 and 9: It is unclear what “manufacture frame units” are. Is this equivalent to saying “to create frame units”? It is assumed so and will be examined accordingly. However, it is unclear what frame units are. Are they “semi-units”? Regarding claim 10: It is unclear if the “lower horizontal frames” and the “fixing bracket” are the same as already recited in claim 8 from which this claim depends. It is assumed this is correct and will be examined accordingly, however, this needs to be clarified by referring back to the elements previously recited or addressing them as additional elements. Regarding claims 11-17: It is unclear how these claims further limit the claims from which they depend. They appear to contain limitations already set forth in the independent claims from which they depend. Regarding claim 12: It is unclear on both sides of what the semi-units are arranged. Additional claims rejected under 35 USC 112 but not addressed are rejected as being dependent on a rejected base claim and failing to further remedy the issue(s). Allowable Subject Matter Claims 1-19 would be allowable if rewritten or amended 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. The following is a statement of reasons for the indication of allowable subject matter: the closest prior art of record being Naim Ibrahim (US Patent No 11,377,847) teaches the elements of the base unit but fails to teach the height adjustment bolts. It would not have been obvious to one of ordinary skill to add height adjustment bolts to the device of Naim Ibrahim. Additionally, Naim Ibrahim does not teach the location of the fixing bracket and would not be obvious to relocate it to the specific location in the instant claims. Response to Arguments Applicant’s arguments, see pages 15-17, filed January 16, 2026, with respect to the drawings and 35 USC 112 have been fully considered and are persuasive. The drawing objections and 35 USC 112 rejection of the claims has been withdrawn. However, new rejections have been presented based on new amendments. Conclusion THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
