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 18 is rejected under 35 U.S.C. 103 as being unpatentable over Zeng et al. (CN114740590, Of record, see IDS dated 3/26/2024, English translation attached).
Regarding claim 18, Zeng discloses the invention as described in Claim 15 and further teaches wherein EFL is an effective focal length of the optical imaging lens (fig.9, paragraph [0153] the optical lens 100 with a focal length F = 6.932mm), T1 is a thickness of the first lens element (fig.9, lens L1) along the optical axis, T6 is a thickness of the sixth lens element (fig.9, lens L6) along the optical axis, G12 is an air gap between the first lens element (fig.9, lens L1) and the second lens element (fig.9, lens L2) along the optical axis, G78 is an air gap between the seventh lens element (fig.9, lens L7) and the eighth lens element (fig.9, lens L8) along the optical axis, and the optical imaging lens satisfies the relationship: EFL/(T1+G12+T3+T6+G78)≤1.900 (1.99; see paragraph [0155], data of table 9, EFL/(T1+G12+T3+T6+G78) = 6.932/(0.838+0.1+0.514+0.677+1.341)=1.99------it has been held that where the general conditions of a claim are disclosed in the prior art, discovering the optimum range or workable ranges involves only routine skill in the art. See MPEP § 2144.05 Section II, Subsection A, citing In re Aller,105 USPQ 233 (C.C.P.A. 1955) --- thus, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to optimize the effective focal length of the optical imaging lens to fit into the claimed range of the above expression, in order to achieve large image size imaging in optical lenses and shorten lens length to achieve miniaturization while maintaining good image quality are problems that the industry urgently needs to solve (Zeng, paragraph [0002]).
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure:
Hashimoto of US20170329108 (Fig.3, Fig.5), discloses wherein lens elements included by the optical imaging lens are only the eight lens elements similar in structure to the claimed invention.
Wenren of US20190107690 (Fig.21), discloses wherein lens elements included by the optical imaging lens are only the eight lens elements similar in structure to the claimed invention.
