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 . Response to Amendment The Amendment filed 8/28/26 has been entered. Response to Arguments Applicant’s arguments with respect to the amended claims filed 8/28/26 have been considered as follows. 35 USC 102/103 Rejections of the claims: Applicant’s arguments are moot in view of the new ground rejections. 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) 1-6 is/are rejected under at least one of 35 U.S.C. 102(a)(1) as being anticipated by SHINOHARA (US 20150009578). PNG media_image1.png 562 442 media_image1.png Greyscale PNG media_image2.png 466 422 media_image2.png Greyscale Regarding claim 1, SHINOHARA teaches (Fig. 1, Table 1) An optical imaging system comprising: a first lens having 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 negative refractive power 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 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, wherein a radius of curvature of the image-side surface of the fourth lens is greater than a radius of curvature of the object-side surface of the first lens (18>3.5), wherein a distance from an image-side surface of the fourth lens to an object-side surface of the fifth lens is greater than a distance from an image-side surface of the third lens to an object- side surface of the fourth lens (0.343>0.219), wherein the optical imaging system has a total number of seven lenses having a refractive power, and wherein an absolute value of a radius of curvature of an object-side surface of the second lens is greater than an absolute value of the radius of the object-side surface of the first lens (6.1>3.5). Regarding claim 2, SHINOHARA further teaches (Fig. 1) The optical imaging system of claim 1, wherein the first lens has a convex object-side surface in a paraxial region thereof. Regarding claim 3, SHINOHARA further teaches (Fig. 1) The optical imaging system of claim 1, wherein the second lens has a convex object-side surface in a paraxial region thereof. Regarding claim 4, mutatis mutandis, SHINOHARA teaches in Table 5 all the limitations as stated in claim 1 rejection above, and further teaches The optical imaging system of claim 1, wherein the fourth lens has a convex object-side surface in a paraxial region thereof. Regarding claim 5, SHINOHARA further teaches (Table 1) The optical imaging system of claim 1, wherein the fifth lens has a convex object-side surface in a paraxial region thereof. Regarding claim 6, SHINOHARA further teaches (Table 1) The optical imaging system of claim 1, wherein the seventh lens has a convex object-side surface in a paraxial region thereof. Conclusion The prior art made of record (see the attached PTO-892 form) and not relied upon, which appears to teach at least claim 1 of the instant application, is considered pertinent to applicant's disclosure. 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 extension fee 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 date of this final action.
