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.
The factual inquiries set forth in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), that are applied for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claim 23, 31, and 38 are rejected under 35 U.S.C. 103 as being unpatentable over Lee in view of Cheo (US 20150316748 A1, of record).
Regarding claim 23, Lee teaches the camera of claim 22, and explicitly shows a second prism (192bx) and demonstrates folding of the optical path into three orthogonal axes (Fig. 4).
Lee does not explicitly show the second prism configured to receive light refracted by the lens group and transmitted along the second light path portion, the second prism further configured to transmit the light along a third light path portion of the path of light, wherein the third light path portion is orthogonal to the second light path portion and orthogonal to the first light path portion.
Cheo teaches an analogous camera device having a first prism (702), a lens set (706), and a second prism (708) in such order such that the second prism configured to receive light refracted by the lens group and transmitted along the second light path portion, the second prism further configured to transmit the light along a third light path portion of the path of light (toward the CMOS sensor), wherein the third light path portion is orthogonal to the second light path portion and orthogonal to the first light path portion (Fig. 7, “incident light” is reflected at a right angle by prism 702, and reflected again at another right angle by prism 708).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have combined the teachings of the three orthogonal paths of Lee with the distal prism position of Cheo for the purpose of realizing a desired three dimensional form factor in accordance with design needs.
Regarding claim 31, Lee teaches the optical system of claim 29, and explicitly shows a second prism (192bx) and demonstrates folding of the optical path into three orthogonal axes (Fig. 4).
Lee does not explicitly show the second prism configured to receive light refracted by the lens group and transmitted along the second light path portion, the second prism further configured to transmit the light received from the lens group along a third light path portion of the path of light, wherein the third light path portion is orthogonal to the second light path portion and orthogonal to the first light path portion.
Cheo teaches an analogous camera device having a first prism (702), a lens set (706), and a second prism (708) in such order such that the second prism configured to receive light refracted by the lens group and transmitted along the second light path portion, the second prism further configured to transmit the light along a third light path portion of the path of light (toward the CMOS sensor), wherein the third light path portion is orthogonal to the second light path portion and orthogonal to the first light path portion (Fig. 7, “incident light” is reflected at a right angle by prism 702, and reflected again at another right angle by prism 708).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have combined the teachings of the three orthogonal paths of Lee with the distal prism position of Cheo for the purpose of realizing a desired three dimensional form factor in accordance with design needs.
Regarding claim 38, Lee teaches the device of claim 37, and explicitly shows a second prism (192bx) and demonstrates folding of the optical path into three orthogonal axes (Fig. 4).
Lee does not explicitly show the second prism configured to receive light refracted by the lens group and transmitted along the second light path portion, the second prism further configured to transmit the refracted light toward the image sensor along a third light path portion of the path of light, wherein the third light path portion is orthogonal to the second light path portion and orthogonal to the first light path portion.
Cheo teaches an analogous camera device having a first prism (702), a lens set (706), and a second prism (708) in such order such that the second prism configured to receive light refracted by the lens group and transmitted along the second light path portion, the second prism further configured to transmit the light along a third light path portion of the path of light (toward the CMOS sensor), wherein the third light path portion is orthogonal to the second light path portion and orthogonal to the first light path portion (Fig. 7, “incident light” is reflected at a right angle by prism 702, and reflected again at another right angle by prism 708).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have combined the teachings of the three orthogonal paths of Lee with the distal prism position of Cheo for the purpose of realizing a desired three dimensional form factor in accordance with design needs.
Claims 25, 30, 33, and 40 are rejected under 35 U.S.C. 103 as being unpatentable over Lee (US 20200057313 A1).
Regarding claim 25, Lee teaches the camera of claim 24, and explicitly shows wherein the actuator module further comprises a second OIS VCM configured to move the lens group (lens driver CIRx).
Lee does not explicitly show the lens group is moved along a direction parallel to the tilt axis.
However, folding of the optical path by prisms is known from Lee. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have rearranged the parts of Lee such that the OIS movement is along a direction parallel to the tilt axis since doing so by further folding of the optical path would not change the principle of operation and would otherwise be predictable. MPEP 2144.04 VI. C.
Regarding claim 30, Lee teaches the optical system of claim 29, and explicitly shows wherein the actuator module further comprises an autofocus (AF) VCM actuator to translate the lens group (¶30, ¶120).
Lee does not explicitly show the lens group is translated in a direction parallel to the second light path portion.
However, folding of the optical path by prisms is known from Lee. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have rearranged the parts of Lee such that the AF VCM movement is along a direction parallel to the tilt axis since doing so by further folding of the optical path would not change the principle of operation and would otherwise be predictable. MPEP 2144.04 VI. C.
Regarding claim 33, Lee teaches the optical system of claim 32, and explicitly shows wherein the actuator module further comprises a second OIS VCM configured to move the lens group (¶30, ¶120, autofocusing necessarily implying movement of the lens group along the optical path, which is parallel to the tilt axis of 192ax).
Lee does not explicitly show the lens group is translated in a direction parallel to the second light path portion.
However, folding of the optical path by prisms is known from Lee. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have rearranged the parts of Lee such that the AF VCM movement is along a direction parallel to the tilt axis since doing so by further folding of the optical path would not change the principle of operation and would otherwise be predictable. MPEP 2144.04 VI. C.
Regarding claim 40, Lee teaches the device of claim 39, and explicitly shows wherein the actuator module further comprises a second OIS VCM configured to move the lens group (¶30, ¶120, autofocusing necessarily implying movement of the lens group along the optical path, which is parallel to the tilt axis of 192ax).

MPEP 2144.04 VI. C.
Claims 26, 34, and 35 are rejected under 35 U.S.C. 103 as being unpatentable over Lee as applied to claims 25 and 33 above, and further in view of Saito (US 20210058537 A1, of record).
Regarding claim 26, the modified Lee teaches the camera of claim 25, but does not explicitly show wherein the second OIS VCM actuator comprises: OIS magnets, comprising: a first OIS magnet; and a second OIS magnet opposite the first magnet with respect to the lens group; and OIS coils, comprising: a first OIS coil proximate the first magnet; and a second OIS coil proximate the second magnet and opposite the first OIS coil with respect to the lens group.
Official Notice is taken that optical image stabilization voice coil motors are exceptionally well known, e.g. in the field of ubiquitous mobile phones. For example, Saito explicitly shows wherein a VCM actuator comprises: OIS magnets, comprising: a first OIS magnet (365a); and a second OIS magnet (365b) opposite the first magnet with respect to the lens group; and OIS coils, comprising: a first OIS coil proximate the first magnet (366a); and a second OIS coil proximate the second magnet (366b) and opposite the first OIS coil with respect to the lens group (Figs. 9-12).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have implemented the well known VCM features thereof to implement the optical image stabilization features of the lens driver disclosed by Lee and thus obtained a predictable result.
Regarding claim 34, the modified Lee teaches the optical system of claim 33, but does not explicitly show wherein the second OIS VCM actuator comprises: OIS magnets, comprising: a first OIS magnet; and a second OIS magnet opposite the first magnet with respect to the lens group; and OIS coils, comprising: a first OIS coil proximate the first magnet; and a second OIS coil proximate the second magnet and opposite the first OIS coil with respect to the lens group.
