Office Action

§102
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 . Election/Restrictions Applicant’s election of claims 1-7 in the reply filed on 9/24/26 is acknowledged. Because applicant did not distinctly and specifically point out the supposed errors in the restriction requirement, the election has been treated as an election without traverse (MPEP § 818.01(a)). 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. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claim(s) 1-7 is/are rejected under 35 U.S.C. 102(a)(1) or (2) as being anticipated by SHINOHARA (US 20150212298, of record). PNG media_image1.png 538 430 media_image1.png Greyscale Regarding claim 1, SHINOHARA teaches (Fig. 5, Tables 9,11, Example 5) An optical imaging system comprising: a first lens having a refractive power and a concave image-side surface in a paraxial region thereof; a second lens having a refractive power; a third lens having a refractive power; a fourth lens having a refractive power; a fifth lens having a refractive power; a sixth lens having a negative refractive power (Table 11) and a concave image-side surface in a paraxial region thereof; and a seventh lens having a refractive power, wherein the first to seventh lenses (L1-L7) are sequentially disposed in ascending numerical order along an optical axis of the optical imaging system from an object side of the optical imaging system toward an imaging plane of the optical imaging system, a radius (-4) of curvature of an image-side surface of the fifth lens at the optical axis is greater than a radius (-3150) of curvature of an image-side surface of the third lens at the optical axis, and the optical imaging system satisfies 0.1<R1/R5<0.7 (5/28), where R1 is a radius of curvature of an object-side surface of the first lens at the optical axis, and R5 is a radius of curvature of an object-side surface of the third lens at the optical axis. Regarding claim 2, SHINOHARA further teaches The optical imaging system of claim 1, wherein the object-side surface of the first lens is convex in a paraxial region thereof (Table 9). Regarding claim 3, SHINOHARA further teaches The optical imaging system of claim 1, wherein the second lens has a convex object-side surface in a paraxial region thereof (Table 9). Regarding claim 4, SHINOHARA further teaches The optical imaging system of claim 1, wherein the object-side surface of the third lens is convex in a paraxial region thereof (Table 9). Regarding claim 5, SHINOHARA further teaches The optical imaging system of claim 1, wherein the fourth lens has a concave object-side surface in a paraxial region thereof (Table 9). Regarding claim 6, SHINOHARA further teaches The optical imaging system of claim 1, wherein the sixth lens has a convex object-side surface in a paraxial region thereof (Table 9). Regarding claim 7, SHINOHARA further teaches The optical imaging system of claim 1, wherein the seventh lens has a convex object-side surface in a paraxial region thereof (Table 9).
