Office Action

§102 §103
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 . Claim Objections Claims 4, 16, and 19 are objected to because of the following informalities: “…and 0.4≤f1/f2≤0. Appropriate correction is required. For the purpose of examination this was interpreted as, “-0.4≤f1/f2≤0”. 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)(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) 1-4, 6, 9, 11, and 13-20 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Chen (US 20220365317 A1).

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) 5 is rejected under 35 U.S.C. 103 as being unpatentable over Chen in view of Kuo (US 20200012078 A1). Re Claim 5, Chen discloses, the optical lens according to claim 1. But Chen does not explicitly disclose, wherein the optical lens has an F-value F #, and 1.55≤F #≤2.1. Kuo teaches that in the prior art, f-number is a variable which achieves a recognized result, and that by changing f-number (or F-value or Fno) one can better control the depth of field or the exposure speed [Par 84], further Kuo teaches such optimizing of f-number to result in various embodiments with Fno between 1.70 and 1.84 (See Tables 1, 3, 5, etc.). Thus, it is known in the prior art to adjust or change the f-value of a lens system, and that it is known that doing so provides the benefit of controlling the depth of field [Kuo: Par 84]. Optimizing f-value or f-number is well within the bounds of normal experimentation. See MPEP 2144.05 II (A). “[W]here the general conditions of a claim are disclosed in the prior art, it is not inventive to dis­cover the optimum or workable ranges by routine experimentation.” In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955). Furthermore, “[a] particular parameter must first be recognized as a result-effective variable, i.e., a variable which achieves a recognized result, before the determination of the optimum or workable ranges of said variable might be characterized as routine experimentation.” In re Antonie, 559 F.2d 618, 195 USPQ 6 (CCPA 1977). Therefore, the prior art teaches adjusting f-number and identifies said sizes/ratios as result-effective variables. Accordingly, it would have been obvious to one of ordinary skill in the art before the effective time of filing to optimize F# such that, 1.55≤F #≤2.1, since it is not inventive to dis­cover the optimum or workable ranges by routine experimentation. Claim(s) 12 is rejected under 35 U.S.C. 103 as being unpatentable over Chen. Re claim 12, Chen discloses, the optical lens according to claim 1. But Chen does not explicitly disclose, wherein the second lens has a central thickness d2, the object side surface of the second lens has a curvature radius R3, an image side surface of the second lens has a curvature radius of R4, and 1<d2(R3+R4)/(R3–R4)<5. Optimizing the thickness of a second lens and the radius of curvature of of the object side surface of the second and lens and the image side surface of the second lens, is well within the bounds of normal experimentation. See MPEP 2144.05 II (A). “[W]here the general conditions of a claim are disclosed in the prior art, it is not inventive to dis­cover the optimum or workable ranges by routine experimentation.” In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955). Furthermore, “[a] particular parameter must first be recognized as a result-effective variable, i.e., a variable which achieves a recognized result, before the determination of the optimum or workable ranges of said variable might be characterized as routine experimentation.” In re Antonie, 559 F.2d 618, 195 USPQ 6 (CCPA 1977). In the case at hand, Chen teaches R3 and R4 as variables, which achieves a recognized result, balancing spherical aberration [Par 11 and 56] and general lens thickness (which would apply to d2) as a variable which would achieve a recognized result, balancing field curvature [Par 59]. Therefore, the prior art teaches adjusting the radiuses R3 and R4 as well as lens thickness (such as d2) and identifies said sizes/ratios as result-effective variables. Accordingly, it would have been obvious to one of ordinary skill in the art before the effective time of filing to optimize the teaching of Chen such 1<d2(R3+R4)/(R3–R4)<5, since it is not inventive to dis­cover the optimum or workable ranges by routine experimentation. Allowable Subject Matter Claims 7-8, and 10 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Wenren (US 20210263287 A1) teaches an optical system with a large image height at least two lenses.
