Regarding claim 18, Xiang teaches the method according to claim 16, further comprising: moving the secondary lenses and primary lenses into close proximity with one another; and aligning the magnetic member in the one of the primary lenses and the secondary lenses with the non-magnetic member in the other of the primary lenses and the secondary lenses (see Fig. 3: the auxiliary lenses are attached to the primary frame). Regarding claim 19, Xiang teaches the method according to claim 18, further comprising bringing the magnetic member and the non-magnetic member into direct contact with one another (see Fig. 3: the auxiliary lenses are attached to the primary frame with the help of magnet 24 and non-magnetic 42). Claim(s) 1 and 2 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Chen US 6,655,799. Regarding claim 1, Chen teaches an eyewear assembly (see at least Fig. 5) comprising: primary lenses (Fig. 5: lenses 16 and 18 are primary lenses); secondary lenses (Fig. 5: lenses 26 and 28 are secondary/auxiliary lenses); a connector assembly detachably securing the primary lenses and the secondary lenses to one another (col. 5 lines 22-51 and Fig. 5: teaches magnetic attachment system that detachably secures the clip-on lenses 26/28 to the base lenses 16/18); wherein the connector assembly comprises: a magnetic member (magnet 30) provided in one of the primary lenses and the secondary lenses (as shown in Fig. 5: magnet 30 is provided in auxiliary lenses 26/28); and a non-magnetic member (ferromagnetic head 34) provided in the other of the primary lenses and the secondary lenses (see col. 5 lines 22-37 and Fig. 5: ferromagnetic head/studs 34 provided on the primary lenses 16/18, i.e., ferromagnetic materials are such as iron, nickel and cobalt that exhibit strong magnet attraction). Regarding claim 2, Chen teaches the eyewear assembly according to claim 1, wherein the non-magnetic member is comprised of a material which is attractable to the magnetic member (see col. 2 lines 6-8: “an attraction between the ferromagnetic studs and the lenses having magnetic elements contained therein”). 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. Claim(s) 4 and 20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Xiang as applied to claim 3 above, and further in view of Smith US 2008/0088791. Regarding claim 4, Xiang teaches the eyewear assembly according to claim 3, except for wherein the metal is stainless steel. However, as discussed see col. 2 lines 6-8: Chen teaches an attraction between the ferromagnetic studs and the lenses having magnetic elements contained therein, i.e., magnetic attachment system for detachably securing secondary lenses to primary lenses using magnets and ferromagnetic metal members), Accordingly, it would have been obvious to one of ordinary skill in the art at the time of the invention to form the ferromagnetic metal member of stainless steel, as stainless steel is a well-known and commonly used metal in eyewear components due to its corrosion resistance, durability, and suitability for magnetically attractable hardware. The selection of stainless steel represents a routine and predictable choice of material that does not result in any unexpected technical effect and therefore does not impart patentable distinction. In any event, Smith discloses magnetic attachment system for securing auxiliary eyewear where the non-magnetic ferromagnetic material is made of stainless-steel material (see para 0097 and 0194: “It includes any ferromagnetic and ferrimagnetic materials, such as, but not limited to, rare earth magnets (e.g. micromagnets as described herein), steels, stainless steels”). Accordingly, it would have been obvious to one of ordinary skill in the art at the time of the invention to form the ferromagnetic metal member of stainless steel, as stainless steel is a well-known and commonly used metal in eyewear components due to its corrosion resistance, durability, and suitability for magnetically attractable hardware. Regarding claim 20, Xiang teaches the method according to claim 16, except for wherein providing the non-magnetic member includes providing a rod of stainless steel capable of being attracted to a magnet. In any event, Smith discloses magnetic attachment system for securing auxiliary eyewear where the non-magnetic ferromagnetic material is made of stainless-steel material (see para 0097 and 0194: “It includes any ferromagnetic and ferrimagnetic materials, such as, but not limited to, rare earth magnets (e.g. micromagnets as described herein), steels, stainless steels”). Accordingly, it would have been obvious to one of ordinary skill in the art at the time of the invention to form the ferromagnetic metal member of stainless steel, as stainless steel is a well-known and commonly used metal in eyewear components due to its corrosion resistance, durability, and suitability for magnetically attractable hardware. Claim(s) 9-13 and 17 is/are rejected under 35 U.S.C. 103 as being unpatentable over Xiang as applied to claim 3 above, and further in view of Rattelade US 2017/0315383. Regarding claim 9, Xiang teaches the eyewear assembly according to claim 1, and Xian further teaches an eyewear assembly including primary lenses and secondary lenses detachably secured by magnetic and non-magnetic members received in apertures or recesses associated with the lenses and/or frame (see para 0021 and Figs. 4-5). However, Xiang fails to teach wherein a notch originates in a peripheral edge of the lens of the primary lenses and the one of the magnetic member and the non-magnetic member is received in the notch. In the same field of endeavor, Rattelade discloses eyewear lenses having notches originating in peripheral edges of the lenses, wherein attachment members are received in the notches to secure auxiliary components to the primary lenses (see Figs. 7, 9 and 10: notch 134/ 234 formed on the edge of lens 218e). Accordingly, it would have been obvious to one of ordinary skill in the art before the effective filing date to modify the eyewear assembly of Xiang such that the magnetic member or the non-magnetic member is received in a notch originating in a peripheral edge of the primary lens as taught by Rattelade, in order to facilitate assembly, accommodate lens curvature, reduce material removal and provide a predictable and affective attachment structure. Regarding claim 10, the combination of Xiang and Rattelade teaches the eyewear assembly according to claim 9, and Rattelade further teaches wherein the notch extends between an outer surface and an inner surface of the lens of the primary lenses (as shown in Figs. 7, 9 and 10: notch 134/234 extends between the inner and outer lenses 128e/218e). Regarding claim 11, the combination of Xiang and Rattelade teaches the eyewear assembly according to claim 9, and Rattelade further teaches wherein a region of a wall of the lens which defines the notch is complementary in configuration to a portion of a circumferential surface of the one of the magnetic member and the non-magnetic member received in the notch (as shown in Fig. 9: notch 234 is complementary to and magnet 256). Regarding claim 12, the combination of Xiang teaches the eyewear assembly according to claim 9, and Xiang teaches further comprising a securement mechanism provided on the primary lenses, wherein the securement mechanism retains the one of the magnetic member and the non-magnetic member in the notch (Xiang teaches magnet holder, sleeves, and ledge that retain magnetic/non-magnetic members in recesses, which constitute a securement mechanisms (Figs. 4-5), while Rattelade teaching forming such recesses as notches in peripheral edges of lenses (Fig. 9)). Regarding claim 13, the combination of Xiang teaches the eyewear assembly according to claim 12, wherein the securement mechanism comprises a portion of a frame of the primary lenses (as discussed with respect to claim 12, Xiang discloses magnet holders, sleeves, and lodges that retain magnetic or non-magnetic members in opening associated with eyewear lenses, which constitute a securement mechanism), and Rattelade further discloses eyewear assemblies in which portions of a frame overlap lens edges and retain attachment members positioned at the lens periphery (at least in Fig. 9). Accordingly, it would have been obvious to one of ordinary skill in the art before the effective filing date to implement the securement mechanism of Xiang as a portion of the frame of the primary lens, as taught by Rattelade, in order to simplify construction, reduce part count, and provide robust retention of the member received in the notch. Regarding claim 17, the combination of Xiang teaches the method according to claim 16, further comprising: except for defining a notch in the at least one eyeglass lens; defining an aperture in the at least one sunglass lens; installing he one of the magnetic member and the non-magnetic member in the notch defined in the at least one eyeglass lens; and installing the other of the magnetic member and the non-magnetic member in the aperture defined in the at least one sunglass lens. Rattelade further discloses forming a notch originating in a peripheral edge of an eyeglass lens and installing an attachment member in the notch (see Fig. 9). Accordingly, it would have been obvious to one of ordinary skill in the art to modify the method of Xiang to include defining a notch in the eyeglass lens and installing one of the magnetic member or the non-magnetic member in the notch, as taught by Rattelade while installing the other member in an aperture of the sunglass lens, in order to facilitate assembly, accommodate lens geometry, and provide a predictable and effective attachment arrangement. Claim(s) 14 is/are rejected under 35 U.S.C. 103 as being unpatentable over Xiang and Rattelade as applied to claim 12 above, and further in view of Lam et al. US 2012/0099074. Regarding claim 14, the combination of Xiang and Rattelade teaches the eyewear assembly according to claim 12, except for wherein the securement mechanism comprises a length of a nylon wire provided on the primary lenses. Lam teaches that a rim wire used to retain eyewear lenses can be fishing wire (e.g., nylon cord), i.e., nylon wire retention element (see para 0031). Accordingly, it would have been obvious to one of ordinary skill in the art to implement the securement mechanism retaining the member in the lens-edge notch as a length of nylon wire, as taught by the nylon core/wire retention element of Lam in order to support by nylon monofilament mounting systems routed along the lens-edge grooves.
