Office Action

§103
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application is being examined under the pre-AIA first to invent provisions. Response to Amendment The amendments filed on 7/29/2025 does not put the application in condition for allowance. Examiner withdraws all rejections in the prior office action due to the amendments. Claim Rejections - 35 USC § 103 The following is a quotation of pre-AIA 35 U.S.C. 103(a) which forms the basis for all obviousness rejections set forth in this Office action: (a) A patent may not be obtained though the invention is not identically disclosed or described as set forth in section 102, if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. Patentability shall not be negatived by the manner in which the invention was made. The factual inquiries set forth in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), that are applied for establishing a background for determining obviousness under pre-AIA 35 U.S.C. 103(a) 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) 1-6 is/are rejected under pre-AIA 35 U.S.C. 103(a) as being unpatentable over Dalland (US Pub No. 2011/0277809) in view of Ward (US Pub No. 2005/0201087) and Daniel (US Pub No. 2011/0290296) Regarding Claim 1, Dalland et al. teaches a flexible solar panel [Fig. 1, Abstract] comprising: a flexible sheet substrate [120, Fig. 1, Abstract, 0026, and 0035]; and a flexible photovoltaic module [110, fig. 1, Abstract, 0024, and 0010 where amorphous silicon is taught as the material of the photovoltaic, which is the same material used by applicant, see claim 4] coupled to the flexible sheet substrate [120, Fig. 1, 0026, and 0035], Dalland et al. is silent on a flexible sheet-metal substrate, a plurality of tensioning rods extending from attachment locations at opposing edges of the flexible sheet metal substrate in directions away from the flexible sheet metal substrate, wherein the tensioning rods are co-planar with the flexible sheet metal substrate at the attachment locations, wherein the flexible solar panel is configured to structurally withstand a tensioning force imparted through tensioning rods, twisting under the tensioning force, and warping under the tensioning force. Ward et al. teaches a tension mechanism comprising a tension rod [1 and 2, Fig. 1, 0016] which is coplanar with a substrate sheet [3, Fig. 1, 0016]. The tension rod allows the structure to be tensioned [0016-0018]. Since Dallad et al. teaches the use of a substrate and the tensioning of the substrate [0029] and substrate 120 is attached to poles 125 in figure 1, it would have been obvious to one of ordinary skill in the art before the filing of the invention to provide the poles of Dallad et al. with the tension mechanism of Ward et al. as it is merely the selection of conventional engineering design for adjusting tension on a substate in the art and one of ordinary skill would have a reasonable expectation of success in doing so. Daniel et al. teaches amorphous silicon solar cells on a flexible substrate made of a thin stainless steel [0024, 0029, the flexible substrate comprises stainless steel] or a polymer [0029]. Since Dalland et al. teaches an amorphous silicon solar cell on a substrate made of a polymer [0010], and Daniel et al. teaches an amorphous silicon solar cell on a flexible substrate made of a stainless steel or a polymer [0029], it would have been obvious to one of ordinary skill in the art at the time the invention was made to replace the substrate of Dalland et al. with the flexible substrate of Daniel et al. as is merely the selection of a conventional substrate material for amorphous silicon solar cells recognized in the art and one of ordinary skill would have a reasonable expectation of success in doing so. The combination of familiar elements is likely to be obvious when it does no more than yield predictable results. See KSR International Co. v. Teleflex Inc., 550 U.S. 398, 415-421, 82 USPQ2d 1385, 1395 – 97 (2007) (see MPEP § 2143, A.). Since modified Dalland et al. teaches a substrate made of the same material as the instant application and comprises the structural limitations of the claim, it is the view of the examiner, the properties of the flexible solar panel of modified Dalland et al. are inherently possessed by the flexible solar panel of modified Dalland et al. meeting the limitation of “wherein the flexible solar panel is configured to structurally withstand a tensioning force imparted through tensioning rods, twisting under the tensioning force, and warping under the tensioning force.” Regarding product and apparatus claims, when the structure recited in the reference is substantially identical to that of the claims, claimed properties or functions are presumed to be inherent. The Courts have held that it is well settled that where there is a reason to believe that a functional characteristic would be inherent in the prior art, the burden of proof then shifts to the applicant to provide objective evidence to the contrary. See In re Schreiber, 128 F.3d at 1478, 44 USPQ2d at 1478, 44 USPQ2d at 1432 (Fed. Cir. 1997) (see MPEP § 2112.01, I.). Since the PTO does not have proper means to conduct experiments, the burden of proof is now shifted to applicants to show otherwise. In re Best, 562 F.2d 1252, 195 USPQ 430 (CCPA 1977); In re Fitzgerald, 205 USPQ 594 (CCPA 1980). Regarding Claim 2, within the combination above, modified Dalland et al. teaches wherein the flexible sheet-metal substrate comprises stainless steel [see rejection of claim 1]. Regarding Claim 3, within the combination above, modified Dalland et al. teaches the flexible photovoltaic module comprising a plurality of photovoltaic cells [110, Fig. 1, 0024]. Regarding Claim 4, within the combination above, modified Dalland et al. teaches wherein the plurality of photovoltaic cells comprises amorphous silicon photovoltaic cells [0010]. Regarding Claim 5, within the combination above, modified Dalland et al. teaches wherein the flexible photovoltaic module is laminated to the flexible sheet-metal substrate [0037, see rejection of claim 1]. Regarding Claim 6, within the combination above, modified Dalland et al. teaches wherein the flexible photovoltaic module is coupled to the flexible sheet-metal substrate with an adhesive [0037]. Claim 7 is/are rejected under pre-AIA 35 U.S.C. 103(a) as being unpatentable over Dalland (US Pub No. 2011/0277809) in view of Ward (US Pub No. 2005/0201087) and Daniel (US Pub No. 2011/0290296) as applied above in addressing claim 1, in further view Fornage (US Pub No. 2009/0084426) Regarding Claim 7, within the combination above, modified Dalland et al. teaches further comprising an inverter electrically coupled to the plurality of photovoltaic cells configured to convert direct current (DC) to alternating current (AC) [0049]. Dalland et al. is silent on a micro-inverter. Fornage et al. teaches an output module with an inverter where the inverter can be a micro-inverter [0024] used in conjunction with a universal interface for a flexible solar system design [0024]. Since modified Dalland et al. teaches an inverter for an flexible solar cell module [0049, Abstract], it would have been obvious to one of ordinary skill in the art before the filing of the invention to utilize the micro-inverter of Fornage et al. with the inverter of Dalland et al. as it is merely the selection of a known power output means for PV modules known in the art and one of ordinary skill would have a reasonable expectation of success in doing so. The combination of familiar elements is likely to be obvious when it does no more than yield predictable results. See KSR International Co. v. Teleflex Inc., 550 U.S. 398, 415-421, 82 USPQ2d 1385, 1395 – 97 (2007) (see MPEP § 2143, A.). Response to Arguments Applicant’s arguments with respect to claim(s) 1-7 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). 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.
