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.
Claims 1-20 are rejected under 35 U.S.C. 103 as being unpatentable over Im et al. (hereafter Im, of record see IDS dated 12/20/2024) US 20180367714 A1 in view of Hu et al. (hereafter Hu, or record) US 20180329276 A1 and in view of Cheong et al. (hereafter Cheong, or record) US 20100060966 A1.
In regard to intendent claim 1, Im teaches (see Figs. 1-14) a camera actuator (i.e. as camera module with OIS, AF and zoom actuators, see Abstract, e.g. paragraphs [3-25,55-69,71-88]) comprising:

wherein the prism unit (1110, 1120) includes: a prism ( prism reflecting member 1110, paragraphs [64, 84-96]); and
a prism mover disposed to surround the prism (i.e. as moving holder 1120 around and for prism 1110, e.g. paragraphs [76-96]),
wherein the first driving unit rotates the prism (1110), the prism mover (1120), of the prism unit about a first virtual line serving as a first rotational axis with respect to the housing and rotates the prism (1110), the prism mover (1120) of the prism unit about a second virtual line perpendicular to the first virtual line serving as a second rotational axis with respect to the housing, (i.e. as 1140 rotates 1120, 1110 and holding part of 1120 for 1110 with respect to 1010 about left-right virtual axis direction, OIS X, and rotated about up-down virtual axis direction (OIS Y) that are perpendicular, with three magnet-coil units 1141a,b, 1143a,b 1145a,b, Figs. 3-4, paragraphs [81-83, 91-96,109-117]).
But Im is silent that the prism mover includes and moves a second driving unit disposed between the prism and the prism mover and that second driving unit rotates the prism about the first virtual line and the second virtual line as the first and second rotational axes with respect to the housing and the prism mover, and that a driving displacement of the second driving unit is smaller than a driving displacement of the first driving unit.
However, Hu teaches in same filed of inventions (see Figs. 1-10) of a camera actuator (optical system to control the reflecting unit for optical image stabilization (OIS) and focus e.g. 100, see title, abstract, paragraphs [2, 6-13,28-39]), and further teaches that that the prism mover includes and moves a second driving unit (DA2,DA3) disposed between the prism (302) and the prism mover (as DA1 moves/tilts 310, with prism 302, holder/frame 304,308 with 2nd, 3rd driver assemblies DA2,DA3, see paragraphs [31, 35-37], Figs. 1-3, and DA2,DA3 is between mover 304, 308 with prism 302, and DA1 as depicted in Figs. 1-2, 4-6, paragraphs [28-39], Figs. 1-3, allowing driving assemblies to control the reflecting unit(prism) to adjust the focus position of the reflecting light on the light-sensing element, for optical image stabilization improving the image quality paragraphs [11, 53]) and that the second driving unit (DA2,DA3 rotates the prism about the first virtual line and the second virtual line as the first and second rotational axes with respect to the housing and the prism mover (i.e. as DA2 rotates 302,308 in up-down virtual direction rotational Ax, Y axis on slated surface of 308,306, and DA3 rotates 302,308 in left-right virtual direction s rotation along Ay , Z axis on slated surface of 308,306 with respect to base 312, 300, as depicted in Figs. 1-2, 4-6, paragraphs [28-39] Figs. 1-3.
Further, Cheong teaches in the related field of invention of piezoelectric actuator and method for driving a mirror (see Figs. 1-8, abstract, e.g. paragraphs [9-25, 38-50]) and further teaches second driving unit disposed between the prism and the mover and rotates the prism about the first virtual line and the second virtual line as the first and second rotational axes with respect to the housing, (i.e. as micromirror device 1 with piezoelectric elements 10,10a-d with support 20, hinge member 30and post 40 between base 11 and reflective element, mirror 50, and rotates 50 around X-axis, and Y-axis, with method for driving 50, e.g. paragraphs [38-51], as depicted in Figs. 2-4, 7 providing precise movement control and adjustment of the micromirror using feedback and misplacement error detection, e.g. paragraphs [11-13, 21-24, 41, 48]).

Further, as a result of the combination of Im with Cheong and Hu, the combination also teaches and renders obvious that the first driving unit tilts the prism, the prism mover, and also the second driving unit (as 1140 rotates/tilts 1120, 1110, and the included DA2/DA3 of Hu and modified by Cheong, in left-right direction (OIS X) and up-down direction (OIS Y) that are with three magnet-coil units 1141a,b, 1143a,b 1145a,b, Figs. 3-4, paragraphs [81-83, 91-96,109-117], with Hu in Figs. 3-6, paragraphs [31-39], and Cheong paragraphs [38-51], Figs. 2-4), and that a driving displacement of the second driving unit is smaller than a driving displacement of the first driving unit (given that piezoelectric actuator elements 10 provide small precise movements to the reflecting micromirror, see Im, e.g. paragraphs [11-13, 21-24, 41, 48-49], while first driving unit for driving the prism unit as 1st driving part 1140 for driving 1120 with 1110 provides rotations of the moving holder with reflecting prism using VCMs having magnets and coils , e.g. paragraphs [77-94], e.g. Figs. 3-4).

a prism mover disposed to surround the prism (i.e. as moving holder 1120 around and for prism 1110, e.g. paragraphs [76-96]),
wherein the first driving unit rotates the prism (1110), the prism mover (1120), of the prism unit about a first virtual line serving as a first rotational axis with respect to the housing and rotates the prism (1110), the prism mover (1120) of the prism unit about a second virtual line perpendicular to the first virtual line serving as a second rotational axis with respect to the housing, (i.e. as 1140 rotates 1120, 1110 and holding part of 1120 for 1110 with respect to 1010 about left-right virtual axis direction, OIS X, and rotated about up-down virtual axis direction (OIS Y) that are perpendicular, with three magnet-coil units 1141a,b, 1143a,b 1145a,b, Figs. 3-4, paragraphs [81-83, 91-96,109-117]).
But Im is silent that the prism mover includes and moves a second driving unit disposed between the prism and the prism mover and that second driving unit rotates the prism about the first virtual line and the second virtual line as the first and second rotational axes with respect to the housing and the prism mover, and that a driving displacement of the second driving unit is smaller than a driving displacement of the first driving unit.
However, Hu teaches in same filed of inventions (see Figs. 1-10) of a camera actuator (optical system to control the reflecting unit for optical image stabilization (OIS) and focus e.g. 100, see title, abstract, paragraphs [2, 6-13,28-39]), and further teaches that that the prism mover includes and moves a second driving unit (DA2,DA3) disposed between the prism (302) and the prism mover (as DA1 moves/tilts 310, with prism 302, holder/frame 304,308 with 2nd, 3rd driver assemblies DA2,DA3, see paragraphs [31, 35-37], Figs. 1-3, and DA2,DA3 is between mover 304, 308 with prism 302, and DA1 as depicted in Figs. 1-2, 4-6, paragraphs [28-39], Figs. 1-3, allowing driving assemblies to control the reflecting unit(prism) to adjust the focus position of the reflecting light on the light-sensing element, for optical image stabilization improving the image quality paragraphs [11, 53]) and that the second driving unit (DA2,DA3 rotates the prism about the first virtual line and the second virtual line as the first and second rotational axes with respect to the housing and the prism mover (i.e. as DA2 rotates 302,308 in up-down virtual direction rotational Ax, Y axis on slated surface of 308,306, and DA3 rotates 302,308 in left-right virtual direction s rotation along Ay , Z axis on slated surface of 308,306 with respect to base 312, 300, as depicted in Figs. 1-2, 4-6, paragraphs [28-39] Figs. 1-3.

In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
Applicant’s arguments, filed in the Remarks dated 03/27/2026 with respect to anticipatory rejection of claim 1over Hu reference have been fully considered and are persuasive. The rejection of claim 1 over Hu reference has been withdrawn.
Applicant's arguments filed in the Remarks dated 03/27/2026 regarding the obviousness rejection over cited prior art of Im, Hu and Cheong, have been fully considered but they are not persuasive. Specifically, Applicant argues on pages 15-16 of the Remarks that the cited prior art of Hu either alone or when used in combination does not disclose that (1) “a first driving unit that drives the prism unit, wherein the prism unit includes a prism; a prism mover disposed to surround the prism; and a second driving unit disposed between the prism and the prism mover and that drives the prism, wherein the first driving unit rotates the prism, the prism mover, and the second driving unit of the prism unit about a first virtual line serving as a first rotational axis with respect to the housing and rotates the prism, the prism mover, and the second driving unit of the prism unit about a second virtual line perpendicular to the first virtual line serving as a second rotational axis with respect to the housing, wherein the second driving unit rotates the prism about the first virtual line and the second virtual line as the first and second rotational axes with respect to the housing and the prism mover, and wherein a driving displacement of the second driving unit is smaller than a driving displacement of the first driving unit”, as Im doesn’t not disclose second driving, Hu does not apply as explained for anticipation rejection and has different driving units, and Cheong, fails to overcome the deficiencies of Im and Hu, however, without providing further reasons and explanations. The Examiner respectfully disagrees. With respect to issue (1) as noted in the rejections above, the cited prior art of Im teaches most limitations of amended claims 1 and 13 and in combination with cited prior art of Hu and Cheong teaches and renders obvious all limiations of claim 1 (as well as claim 13) as, Im teaches (see Figs. 1-14) a camera actuator (i.e. as camera module with OIS, AF and zoom actuators, see Abstract, e.g. paragraphs [3-25,55-69,71-88]) comprising:
a housing (e.g. 1010, paragraphs [63, 68-82]);
a prism unit disposed in the housing (prism 1110 and moving holder 1120, paragraphs [76-88]); and

wherein the prism unit (1110, 1120) includes: a prism ( prism reflecting member 1110, paragraphs [64, 84-96]); and
a prism mover disposed to surround the prism (i.e. as moving holder 1120 around and for prism 1110, e.g. paragraphs [76-96]),
wherein the first driving unit rotates the prism (1110), the prism mover (1120), of the prism unit about a first virtual line serving as a first rotational axis with respect to the housing and rotates the prism (1110), the prism mover (1120) of the prism unit about a second virtual line perpendicular to the first virtual line serving as a second rotational axis with respect to the housing, (i.e. as 1140 rotates 1120, 1110 and holding part of 1120 for 1110 with respect to 1010 about left-right virtual axis direction, OIS X, and rotated about up-down virtual axis direction (OIS Y) that are perpendicular, with three magnet-coil units 1141a,b, 1143a,b 1145a,b, Figs. 3-4, paragraphs [81-83, 91-96,109-117]).
But Im is silent that the prism mover includes and moves a second driving unit disposed between the prism and the prism mover and that second driving unit rotates the prism about the first virtual line and the second virtual line as the first and second rotational axes with respect to the housing and the prism mover, and that a driving displacement of the second driving unit is smaller than a driving displacement of the first driving unit.
Thus Hu was used as Hu teaches in same filed of inventions (see Figs. 1-10) of a camera actuator (optical system to control the reflecting unit for optical image stabilization (OIS) and focus e.g. 100, see title, abstract, paragraphs [2, 6-13,28-39]), and further teaches that that the prism mover includes and moves a second driving unit (DA2,DA3) disposed between the prism (302) and the prism mover (as DA1 moves/tilts 310, with prism 302, holder/frame 304,308 with 2nd, 3rd driver assemblies DA2,DA3, see paragraphs [31, 35-37], Figs. 1-3, and DA2,DA3 is between mover 304, 308 with prism 302, and DA1 as depicted in Figs. 1-2, 4-6, paragraphs [28-39], Figs. 1-3, allowing driving assemblies to control the reflecting unit(prism) to adjust the focus position of the reflecting light on the light-sensing element, for optical image stabilization improving the image quality paragraphs [11, 53]) and that the second driving unit (DA2,DA3 rotates the prism about the first virtual line and the second virtual line as the first and second rotational axes with respect to the housing and the prism mover (i.e. as DA2 rotates 302,308 in up-down virtual direction rotational Ax, Y axis on slated surface of 308,306, and DA3 rotates 302,308 in left-right virtual direction s rotation along Ay , Z axis on slated surface of 308,306 with respect to base 312, 300, as depicted in Figs. 1-2, 4-6, paragraphs [28-39] Figs. 1-3.
Further, Cheong was used as Cheong teaches in the related field of invention of piezoelectric actuator and method for driving a mirror (see Figs. 1-8, abstract, e.g. paragraphs [9-25, 38-50]) and further teaches second driving unit disposed between the prism and the mover and rotates the prism about the first virtual line and the second virtual line as the first and second rotational axes with respect to the housing, (i.e. as micromirror device 1 with piezoelectric elements 10,10a-d with support 20, hinge member 30and post 40 between base 11 and reflective element, mirror 50, and rotates 50 around X-axis, and Y-axis, with method for driving 50, e.g. paragraphs [38-51], as depicted in Figs. 2-4, 7 providing precise movement control and adjustment of the micromirror using feedback and misplacement error detection, e.g. paragraphs [11-13, 21-24, 41, 48]).
Hence, as presented above, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the camera module actuator first driving part for reflective prism member of Im to include the second driving unit, as piezoelectric reflector driver according to teachings of Cheong, and that is disposed between the prism and the prism mover and that rotates the prism about the first virtual line and the second virtual line as the first and second rotational axes extending along slanted inner surface of the prism mover according to teaching of Hu, in order to provide precise movement control and adjustment of the reflector using feedback and misplacement error detection, (see Hu e.g. paragraphs [11-13, 21-24, 41, 48]), and thus allow driving assemblies to control the reflecting unit(prism) to fine adjust focus position for optical image stabilization thereby improving the image quality (see Cheong paragraphs [11, 53]). Further, as a result of the combination of Im with Cheong and Hu, the combination also teaches and renders obvious that the first driving unit tilts the prism, the prism mover, and also the second driving unit (as 1140 rotates/tilts 1120, 1110, and the included DA2/DA3 of Hu and modified by Cheong, in left-right direction (OIS X) and up-down direction (OIS Y) that are with three magnet-coil units 1141a,b, 1143a,b 1145a,b, Figs. 3-4, paragraphs [81-83, 91-96,109-117], with Hu in Figs. 3-6, paragraphs [31-39], and Cheong paragraphs [38-51], Figs. 2-4), and that a driving displacement of the second driving unit is smaller than a driving displacement of the first driving unit (given that piezoelectric actuator elements 10 provide small precise movements to the reflecting micromirror, see Im, e.g. paragraphs [11-13, 21-24, 41, 48-49], while first driving unit for driving the prism unit as 1st driving part 1140 for driving 1120 with 1110 provides rotations of the moving holder with reflecting prism using VCMs having magnets and coils , e.g. paragraphs [77-94], e.g. Figs. 3-4).
Additionally, the teachings of Im, Hu and Cheong are applied in combination. Specifically, as a result of the combination of Im with Cheong and Hu, the combination also teaches and renders obvious that the first driving unit tilts the prism, the prism mover, and also the second driving unit (as 1140 rotates/tilts 1120, 1110, and the included DA2/DA3 of Hu and modified by Cheong, in left-right direction (OIS X) and up-down direction (OIS Y) that are with three magnet-coil units 1141a,b, 1143a,b 1145a,b, Figs. 3-4, paragraphs [81-83, 91-96,109-117], with Hu in Figs. 3-6, paragraphs [31-39], and Cheong paragraphs [38-51], Figs. 2-4), and that a driving displacement of the second driving unit is smaller than a driving displacement of the first driving unit (given that piezoelectric actuator elements 10 provide small precise movements to the reflecting micromirror, see Im, e.g. paragraphs [11-13, 21-24, 41, 48-49], while first driving unit for driving the prism unit as 1st driving part 1140 for driving 1120 with 1110 provides rotations of the moving holder with reflecting prism using VCMs having magnets and coils , e.g. paragraphs [77-94], e.g. Figs. 3-4).
Therefore, the cited prior art of Im with Hu and Cheong teaches and renders obvious the above limitations noted under issue 1, and all limitations in independent claims 1 and 13.
No additional substantial arguments were presented after page 16 of the Remarks dated 03/27/2026.
