0.25 ≤ D12P/DR ≤ 1.0 is satisfied (Table 1 and Fig. 1, D12P/DR=1.0222/3.0000=0.34), where D12P is a distance on an optical axis of the optical imaging system from the image-side surface of the lens disposed closest to the reflective member among the one or two lenses of the first lens group to the incident surface of the reflective member, and DR is a distance on the optical axis from the incident surface of the reflective member to the reflection surface of the reflective member (Fig. 1).
Regarding claim 18, Zhang also teaches the following elements:
(Claim 18) at least three lenses (L3, L4 and L5 in Fig. 1 and Table 1) among the plurality of lenses of the second lens group (L2, L3, L4, L5 and L6 in Fig. 1) have a refractive index greater than 1.6 (Table 1).
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 of this title, 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 2 is rejected under 35 U.S.C. 103 as being unpatentable over Mercado as applied to claim 1 above, and further in view of Lee (US 2023/0131146).
Regarding claim 2, Mercado does not teach the following elements.
Lee teaches the following elements:
(Claim 2) a reflective member (455 in Fig. 7, [0147, 0149-0150]) is configured to be rotatable about two axes perpendicular to each other (Fig. 7, [0147, 0149-0150]).
Before the effective filling date of the claimed invention, it would have been obvious to the artisan of ordinary skill to employ the above elements as taught by Lee for the system of Mercado such that in the system of Mercado,
(Claim 2) the reflective member is configured to be rotatable about two axes perpendicular to each other.
The motivation is to implement a scan or an image stabilization operation (Lee, [0147, 0149]).
Claim 28 is rejected under 35 U.S.C. 103 as being unpatentable over Mercado (US 2015/0253543).
Regarding claim 28, Mercado also teaches that a first lens group is disposed at a fixed position on the optical axis ([0177]), and a second lens groups is configured to be movable along the optical axis relative to the first lens group to adjust a focus of the optical imaging system ([0177]). Before the effective filling date of the claimed invention, it would have been obvious to the artisan of ordinary skill to employ the above elements as taught by Mercado for the system of Fig. 9A-9B and Tables 5A-5E of Mercado such that in the system of Fig. 9A-9B and Tables 5A-5E of Mercado, the first lens group is disposed at a fixed position on the optical axis, and the second lens groups is configured to be movable along the optical axis relative to the first lens group to adjust a focus of the optical imaging system. The motivation is that the object distance or focus displacement range of the focusing lens group may be scaled up or down for larger or smaller implementations of a camera using an embodiment of a folded telephoto lens system (Mercado, [0177]).
Allowable Subject Matter
Claims 3-4, 6, 12, 14, 15, 22 and 27 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.
The following is a statement of reasons for the indication of allowable subject matter:
None of the prior art of record discloses or suggests all the combination of an optical imaging system as set forth in claims 3-4, 6, 12, 14, 15, 22 and 27.
Regarding claims 3-4, none of the prior art discloses or suggests an optical imaging system recited in claim 1, wherein “the one or two lenses included in the first lens group comprise a first lens having an object-side surface that is convex in a paraxial region thereof, and an image-side surface that is concave in a paraxial region thereof, and an effective diameter of the object-side surface of the first lens and an effective diameter of the image-side surface of the first lens are greater than a minor axis length of the incident surface of the reflective member” in combination with the other required elements of the claim.
Regarding claim 6, none of the prior art discloses or suggests an optical imaging system recited in claim 1, wherein “0.35 ≤ DR/L2S1_ED ≤ 0.65 is satisfied, where L2S1_ED is an effective diameter of an object-side surface of a lens disposed closest to the reflective member among the plurality of lenses included in the second lens group” in combination with the other required elements of the claim.
Regarding claim 12, none of the prior art discloses or suggests an optical imaging system recited in claim 1, wherein “1.1 ≤ fG1/L ≤ 1.9 is satisfied, where fG1 is a focal length of the first lens group, and L is a sum of a distance on the optical axis from an object-side surface of a lens disposed closest to an object side of the optical imaging system among the one or two lenses included in the first lens group to the reflection surface of the reflective member, and a distance on the optical axis from the reflection surface of the reflective member to an imaging plane of the optical imaging system” in combination with the other required elements of the claim.
Regarding claim 14, none of the prior art discloses or suggests an optical imaging system recited in claim 1, wherein “0.25 < G1_MED/Lr < 0.42 and 0.7 < G2_MED/Lf < 1.4 are satisfied, where G1_MED is a maximum effective diameter of the one or two lenses included in the first lens group, and G2_MED is a maximum effective diameter of the plurality of lenses included in the second lens group” in combination with the other required elements of the claim.
Regarding claim 15, none of the prior art discloses or suggests an optical imaging system recited in claim 1, wherein “0.35 < f/fG1 ≤ 0.5 is satisfied, where f is a total focal length of the optical imaging system, and fG1 is a focal length of the first lens group” in combination with the other required elements of the claim.
Regarding claim 22, none of the prior art discloses or suggests an optical imaging system recited in claim 21, wherein “there is a total of five lenses having a refractive power in the second lens group, and the five lenses comprise the second lens having the positive refractive power, a third lens having a negative refractive power, a fourth lens having a positive refractive power or a negative refractive power, a fifth lens having a positive refractive power, and a sixth lens having a positive refractive power or a negative refractive power” in combination with the other required elements of the claim.
Regarding claim 27, none of the prior art discloses or suggests an optical imaging system recited in claim 26, wherein “there is a total of six lenses having a refractive power in the second lens group, and the six lenses comprise the second lens having the positive refractive power, a third lens having a positive refractive power, a fourth lens having a negative refractive power, a fifth lens having a negative refractive power, a sixth lens having a positive refractive power, and a seventh lens having a positive refractive power or a negative refractive power” in combination with the other required elements of the claim.
