Regarding Claim 13, Taha et al. is relied upon for the reasons given above, Taha et al. teaches wherein a top of first cradle clamp is disposed above or flush with a top of the first cradle in a second direction, the second direction being perpendicular to the first direction [Fig. 8A, 0050, 0035]. Regarding Claim 14, Taha et al. is relied upon for the reasons given above, Taha et al. teaches wherein a top of second cradle clamp is disposed below a top of the second cradle in a second direction, the second direction being perpendicular to the first direction [Fig. 8A, 0050, 0035]. Regarding Claim 21, Taha et al. is relied upon for the reasons given above, Taha et al. teaches wherein the second axis is coaxial with the rotation axis [Fig. 3A-3C, 0032-0033, 0035, angles between two rotation axes can be positive or negative] Regarding Claim 22, Taha et al. is relied upon for the reasons given above, Taha et al. teaches wherein the second axis is parallel with the rotation axis [Fig. 3A-3C, 0032-0033, 0035, angles between two rotation axes can be positive or negative] Regarding Claim 23, Taha et al. is relied upon for the reasons given above, Taha et al. teaches wherein the first axis is not coaxial with the rotation axis [Fig. 3A-3C, 0032-0033, 0035, angles between two rotation axes can be positive or negative] Regarding Claim 24, Taha et al. is relied upon for the reasons given above, Taha et al. teaches wherein the first axis is coaxial with the rotation axis [Fig. 3A-3C, 0032-0033, 0035, angles between two rotation axes can be positive or negative] Regarding Claim 25, Taha et al. is relied upon for the reasons given above, Taha et al. teaches wherein the second axis is below both the first axis and the rotation axis in a second direction, the second direction perpendicular to the first direction [Fig. 3A-3C, 0032-0033, 0035, angles between two rotation axes can be positive or negative] 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. 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. Claim(s) 15 is/are rejected under 35 U.S.C. 103 as being unpatentable over Taha (WO2018/075368) Regarding Claim 15, Taha et al. is relied upon for the reasons given above, Taha et al. is silent on wherein the first and second solar module mounting structure have a height and length, the height of the first and second solar module mounting structure being substantially identical and the length of the first and second solar module mounting structure being substantially identical, the height and length being perpendicular to each other and the height being perpendicular to the rotation axis and the length being parallel to the rotation axis. As the cost of construction and efficiency of operation are variables that can be modified, among others, by adjusting the parameters of the first and second mounting structure , with said construction cost and operating efficiency both changing as the parameters of the first and second mounting structure are changed, the precise parameters of the first and second mounting structure would have been considered a result effective variable by one having ordinary skill in the art before the filing of the invention. As such, without showing unexpected results, the claimed “wherein the first and second solar module mounting structure have a height and length, the height of the first and second solar module mounting structure being substantially identical and the length of the first and second solar module mounting structure being substantially identical, the height and length being perpendicular to each other and the height being perpendicular to the rotation axis and the length being parallel to the rotation axis.” cannot be considered critical. Accordingly, one of ordinary skill in the art before the filing of the invention would have optimized, by routine experimentation, the parameters of the first and second mounting structure to obtain the desired balance between the construction cost and the operation efficiency (In re Boesch, 617 F.2d. 272, 205 USPQ 215 (CCPA 1980)), since it has been held that where the general conditions of the claim are disclosed in the prior art, discovering the optimum or workable ranges involves only routine skill in the art. (In re Aller, 105 USPQ 223). Response to Arguments Applicant's arguments filed 3/31/2026 have been fully considered but they are not persuasive. Examiner respectfully disagrees. Regarding the new limitations, Taha et al. teaches the first axis being one of above or below the second axis in in a second direction, the second direction being perpendicular to the first direction [3A-3C, 0032-0033, 0035, angles between two rotation axes can be positive or negative]. Taha et al. teaches the first and second axis have a wide range of angles relative to each other. Para. 35 suggest angles from 90 to -90 degrees, meeting the limitations of the claim. 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.
