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 . Priority Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Claim Rejections - 35 USC § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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 1 is rejected under 35 U.S.C. 102(a)(1) as being anticipated by Toyama (USP No. 5,864,435). Regarding claim 1, Toyama discloses an optical imaging lens (see Fig. 1, Col. 3, Line 3), in order from an object side to an image side along an optical axis, comprising: a first lens assembly consisting of (see Fig. 1), in order from the object side to the image side along the optical axis, a first lens (L1) having negative refractive power (Col. 3, Lines 17-18), a second lens (L2) having negative refractive power (Col. 3, Line 19), a third lens (L3) having positive refractive power (Col. 3, Line 19), and a fourth lens (L4) having positive refractive power (Col. 3, Line 20), wherein an image-side surface of the second lens and an object-side surface of the third lens are adhered to form a compound lens (see Fig. 1, Col. 3, Lines 18-20); an aperture (see Fig. 1, Table 1); and a second lens assembly consisting of, in order from the object side to the image side along the optical axis, a fifth lens (L5) having negative refractive power (Table 1), a sixth lens (L6) having positive refractive power (Col. 3, Line 22), and a seventh lens (L7) having negative refractive power (Col. 3, Line 23-24). Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claims 2-6 and 9-22 are rejected under 35 U.S.C. 103 as being unpatentable over Toyama (USP No. 5,864,435) in view of Yue et al. (CN 114967066 A), hereinafter “Yue”.

Regarding claim 7, Toyama discloses the claimed invention except for wherein an object-side surface and an image-side surface of the first lens are aspheric surfaces; an object-side surface and an image-side surface of the seventh lens are aspheric surfaces; an object-side surface and the image-side surface of the second lens are spherical surfaces; the object-side surface and an image-side surface of the third lens are spherical surfaces; an object-side surface and an image-side surface of the fourth lens are spherical surfaces; an object-side surface and an image-side surface of the fifth lens are spherical surfaces; an object-side surface and an image-side surface of the sixth lens are spherical surfaces. In the same field of endeavor, Lee discloses wherein an object-side surface and an image-side surface of the first lens are aspheric surfaces; an object-side surface and an image-side surface of the seventh lens are aspheric surfaces; an object-side surface and the image-side surface of the second lens are spherical surfaces; the object-side surface and an image-side surface of the third lens are spherical surfaces; an object-side surface and an image-side surface of the fourth lens are spherical surfaces; an object-side surface and an image-side surface of the fifth lens are spherical surfaces; an object-side surface and an image-side surface of the sixth lens are spherical surfaces (Paragraph 58). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to provide the lens of Toyama with wherein an object-side surface and an image-side surface of the first lens are aspheric surfaces; an object-side surface and an image-side surface of the seventh lens are aspheric surfaces; an object-side surface and the image-side surface of the second lens are spherical surfaces; the object-side surface and an image-side surface of the third lens are spherical surfaces; an object-side surface and an image-side surface of the fourth lens are spherical surfaces; an object-side surface and an image-side surface of the fifth lens are spherical surfaces; an object-side surface and an image-side surface of the sixth lens are spherical surfaces of Lee for the purpose of facilitating aberration correction (Paragraph 52). Regarding claim 8, Toyama discloses wherein an object-side surface of the seventh lens is convex at a point where the optical axis passes through; an image-side surface of the seventh lens is concave at a point where the optical axis passes through (see Fig. 1, Paragraph 71 – Table 1). Toyama discloses the claimed invention except for the object-side surface of the seventh lens is an aspheric surface and has at least one inflection point; the image-side surface of the seventh lens is an aspheric surface and has at least one inflection point. In the same field of endeavor, Lee discloses the object-side surface of the seventh lens is an aspheric surface and has at least one inflection point; the image-side surface of the seventh lens is an aspheric surface and has at least one inflection point (Paragraph 58). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to provide the lens of Toyama with the object-side surface of the seventh lens is an aspheric surface and has at least one inflection point; the image-side surface of the seventh lens is an aspheric surface and has at least one inflection point of Lee for the purpose of facilitating aberration correction (Paragraph 52). Prior Art Citations Takato (USP No. 11,150,462) is being cited herein to show an optical imaging lens relevant to the claimed invention.
