Office Action

§102 §103
DETAILED ACTION This communication is a first Office Action Non-Final rejection on the merits. The Restriction election received on 02/11/2026 has been acknowledged. Claims 1-20 are pending and have been considered below. Election/Restrictions 1. Applicant’s election of Group I (claims 1-14) and Species 1A, 1B (figures 3A, 3B, 5A) in the reply filed on 02/11/2026 is acknowledged. 2. Claims 15-20 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to nonelected invention Group II. Election was made without traverse in the reply filed on 02/11/2026. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale or otherwise available to the public before the effective filing date of the claimed invention. Claim(s) 1, 5-12, and 14, is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Flahetry et al. (U.S. Pub. No. 2008/0289272). Regarding claim 1, Flahetry et al. teaches a roofing tile assembly (abstract), comprising: a photovoltaic (PV) roofing tile (108), comprising: an optically transparent front cover (610); a back cover (106); a plurality of solar cells (622) disposed between the optically transparent front cover and the back cover (figures 4, 8 and 9); and a plurality of tile hooks (210) coupled to the back cover (figure 4); and a roofing tile base (102), comprising: a sun-facing surface (top surface) in direct contact with the back cover (figure 7) and extending from a first lateral side of the roofing tile to a second lateral side of the roofing tile opposite the first lateral side (figure 4); a plurality of vertical standoffs (116) configured to establish a height of the sun-facing surface above a roofing substrate (figure 5); and a plurality of apertures (180) extending through the roofing tile base (figure 3), wherein a first tile hook of the plurality of tile hooks extends through a first aperture of the plurality of apertures and engages a portion of the roofing tile base defining the first aperture (figures 6-7). Regarding claim 5, Flahetry et al. teaches the plurality of vertical standoffs comprises four or more vertical standoffs (figure 5). Regarding claim 6, Flahetry et al. teaches the roofing tile base is a single piece (abstract). With regards to the limitation that the product is formed by using injection molded, etc., the examiner would like to point out that these limitations are drawn to the method or process of forming the product. Therefore, since this claim is an apparatus claim, the prior art only needs to show the final product. Thus, since Flahetry et al. teaches all of the structural limitations of the claim, the claim stands rejected. See MPEP 2113. Regarding claim 7, Flahetry et al. teaches the roofing tile base is formed from a polymeric material (paragraph 42). Regarding claim 8, Flahetry et al. teaches the PV roofing tile comprises a junction box (310) coupled to the back cover (figure 7) and the roofing tile base defines an electrical component recess (170) that accommodates a height of the junction box between the roofing tile base and the back cover (figures 6-7). Regarding claim 9, Flahetry et al. teaches the roofing tile base includes a plurality of retaining features (182) configured to attach the roofing tile base to a non-PV roofing tile (it is understood that the retaining features are capable of being configured to attach the roofing tile base to a non-PV roofing tile). Regarding claim 10, Flahetry et al. teaches a first vertical standoff of the plurality of vertical standoffs is larger than a second standoff of the plurality of vertical standoffs (as illustrated, some of the vertical standoffs 116 are larger than the ones interrupted by opening 170; figure 5). Regarding claim 11, Flahetry et al. teaches bottom surfaces of the plurality of vertical standoffs cooperatively define a first plane anti-parallel to the sun-facing surface (as illustrated, bottom surfaces of 116 at the notches 320 define a first plane anti-parallel to the sun-facing surface; figure 5). Regarding claim 12, Flahetry et al. teaches the roofing tile base is configured to position a first corner region of the sun-facing surface a first distance from a roofing substrate (arbitrary first corner region; figure 5), a second corner region of the sun-facing surface a second distance from the roofing substrate (arbitrary second corner region; figure 5), a third corner region of the sun-facing surface a third distance from the roofing substrate (arbitrary third corner region; figure 5) and a fourth corner region of the sun-facing surface a fourth distance from the roofing substrate (arbitrary fourth corner region; figure 5). Regarding claim 14, Flahetry et al. teaches the roofing tile base further comprises an integrated sidelap (132) protruding from a lateral side of the roofing tile base (figure 4) and configured to extend beneath a gap between the roofing tile base and another roofing tile base adjacent to the roofing tile base (it is understood that the sidelap is capable of extending beneath a gap between the roofing tile base and another roofing tile base adjacent to the roofing tile base). The examiner notes that the another roofing tile base adjacent to the roofing tile base, is not being positively claimed. 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 of this title, 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. Claim(s) 2-4, is/are rejected under 35 U.S.C. 103 as being unpatentable over Flahetry et al. (U.S. Pub. No. 2008/0289272) in view of Seery et al. (U.S. Pub. No. 2021/026594). Regarding claim 2, Flahetry et al. does not specifically disclose the roofing tile base comprises a plurality of lateral standoffs protruding from a down-roof facing end of the roofing tile base below a sun-facing surface of the roofing tile base. Seery et al. discloses a roofing tile base (figure 5E) comprises a plurality of lateral standoffs (318) protruding from a down-roof facing end of the roofing tile base below a sun-facing surface of the roofing tile base (figure 5E). Therefore, from the teaching of Seery et al., it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention, to modify the photovoltaic panel assembly of Flahetry et al. such that the roofing tile base comprises a plurality of lateral standoffs protruding from a down-roof facing end of the roofing tile base below a sun-facing surface of the roofing tile base, as taught by Seery et al., in order to further secure adjacent roofing tile assemblies, to ensure a consistent alignment and facilitate assembly. Regarding claim 3, Seery et al. in the combination discloses the roofing tile base further comprises a plurality of alignment notches (314) extending into the sun-facing surface of the roofing tile base (figure 5E). Regarding claim 4, Seery et al. in the combination discloses the plurality of alignment notches are configured to receive a lateral standoff of another roofing tile base up-roof of the roofing tile base (figure 5E). Claim(s) 13, is/are rejected under 35 U.S.C. 103 as being unpatentable over Flahetry et al. (U.S. Pub. No. 2008/0289272) in view of Salam (U.S. Pub. No. 2012/0199180). Regarding claim 13, Flahetry et al. does not specifically disclose the first distance is greater than the second distance, the second distance is greater than the third distance and the third distance is greater than the fourth distance. Salam discloses a solar panel frame (abstract) wherein the first distance is greater than the second distance (as illustrated, a first distance of a first corner region, is greater than a second distance at a second corner region; see annotated figure 2 below), the second distance is greater than the third distance (as illustrated, the second distance of the second corner region, is greater than a third distance at a third corner region; see annotated figure 2 below) and the third distance is greater than the fourth distance (as illustrated, the third distance of the third corner region, is greater than a fourth distance at a fourth corner region; annotated figure 2). Therefore, from the teaching of Salam, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention, to modify the photovoltaic panel assembly of Flahetry et al. such that the first distance is greater than the second distance, the second distance is greater than the third distance and the third distance is greater than the fourth distance, as taught by Salam, in order to reduce wind uplift by presenting a less abrupt edge to wind, for a more stable design.
