Claim Rejections - 35 USC § 102
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
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) 1-8, 12-16, 24, and 27 is/are rejected under 35 U.S.C. 102(a)(2) as being anticipated by You et al. (Pub. No. US 2024/0061317 A1; hereafter You) .
The applied reference has a common inventor and assignee with the instant application. Based upon the earlier effectively filed date of the reference, it constitutes prior art under 35 U.S.C. 102(a)(2). This rejection under 35 U.S.C. 102(a)(2) might be overcome by: (1) a showing under 37 CFR 1.130(a) that the subject matter disclosed in the reference was obtained directly or indirectly from the inventor or a joint inventor of this application and is thus not prior art in accordance with 35 U.S.C. 102(b)(2)(A); (2) a showing under 37 CFR 1.130(b) of a prior public disclosure under 35 U.S.C. 102(b)(2)(B) if the same invention is not being claimed; or (3) a statement pursuant to 35 U.S.C. 102(b)(2)(C) establishing that, not later than the effective filing date of the claimed invention, the subject matter disclosed in the reference and the claimed invention were either owned by the same person or subject to an obligation of assignment to the same person or subject to a joint research agreement.
See You Figs. 5 and 8-16a which disclose an aperture device substantially similar to the aperture device called for in claims 1-8, 12-16, 24, and 27 and therefore read on the recited claim limitations.

Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
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.
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(s) 4-6 is/are rejected under 35 U.S.C. 103 as being unpatentable over Oh in view of Iwasaki et al. (US Patent No. 5,140,212; hereafter Iwasaki).
Regarding claims 4-6, Oh discloses the variable aperture according to claim 2, but does not specifically disclose that the outer peripheral side surface of the rotating support recesses toward a center of the rotating support to form a first mounting groove, and at least a part of the first magnet is connected to the first mounting groove; [claim 5] wherein: the variable aperture further comprises a second magnet and a second coil; the second magnet is connected to the outer peripheral side surface of the rotating support; the second coil is fixedly connected to the fixing base, and faces the second magnet; and the second magnet is configured to: when the second coil is powered on, the second magnet is subject to an acting force, that drives the rotating support to rotate relative to the fixing base, wherein a direction in which the second magnet drives the rotating support to rotate relative to the fixing base is the same as a direction in which the first magnet drives the rotating support to rotate relative to the fixing base; [claim 6] wherein the second magnet and the first magnet are center-symmetric with respect to the center of the rotating support.
Iwasaki discloses a variable aperture device wherein the outer peripheral side surface of the rotating support recesses toward a center of the rotating support to form a first mounting groove, and at least a part of the first magnet is connected to the first mounting groove (see Iwasaki Figs. 1 and 3, items 21 and 24); [claim 5] wherein: the variable aperture further comprises a second magnet and a second coil; the second magnet is connected to the outer peripheral side surface of the rotating support (see Iwasaki Figs. 1 and 3, items 24 and 21); the second coil is fixedly connected to the fixing base, and faces the second magnet (see Iwasaki Figs. 1, item 34. While Iwasaki does not explicitly disclose that the coil 34 comprises a plurality of coils that face the plurality of magnets, in order to generate the driving force called for in the Iwasaki reference the coils must face the magnets, as opposed to being wrapped around the circumference of the base. It further would have been obvious to one having ordinary skill in the art to provide coils for each of the magnets in order to increase the drive control of the system); and the second magnet is configured to: when the second coil is powered on, the second magnet is subject to an acting force, that drives the rotating support to rotate relative to the fixing base, wherein a direction in which the second magnet drives the rotating support to rotate relative to the fixing base is the same as a direction in which the first magnet drives the rotating support to rotate relative to the fixing base (while not specifically stated, it would be obvious to have the magnets drive the device in the same direction so that the forces do not work at cross-purposes to one another); [claim 6] wherein the second magnet and the first magnet are center-symmetric with respect to the center of the rotating support (see Iwasaki Figs. 1, 3, and 6, which show that the magnets are symmetrically placed).
It would have been obvious to one having ordinary skill in the art at the time the invention was filed to modify the rotor and stator of Oh to have embedded magnets and coils like that in Iwasaki in order to reduce the amount of space required to mount the components for the aperture drive system.
Claim(s) 17 is/are rejected under 35 U.S.C. 103 as being unpatentable over Oh in view of Chen et al. (Pub. No. US 2021/0124144 A1; hereafter Chen).
Regarding claim 17, Oh discloses the variable aperture according to claim 2, the variable aperture comprises an initial state (see Oh Fig. 9), an intermediate state (see Oh Fig. 8A), and an end state (see Oh Fig. 8B), wherein: when the variable aperture (60) is in the initial state or the intermediate state, a maximum aperture of the light transmission hole (650) of the plurality of blades (65) has a dimension that is less than an aperture of the light transmission hole (see Oh Figs. 8A and 8B, which show the blades opening is smaller than the light transmission hole); and when the variable aperture is in the end state, a minimum aperture of the light transmission hole of the plurality of blades has a dimension that is greater than or equal to the aperture of the light transmission hole (see Oh Fig. 9).
Oh does not disclose that the variable aperture further comprises a gasket, connected to the rotating support and is positioned on a side of the plurality of blades facing the rotating support, the gasket including a light transmission hole, in communication with the light transmission hole of the plurality of blades and the space of the rotating support.
Chen discloses a variable aperture comprising a gasket, connected to the rotating support and is positioned on a side of the plurality of blades facing the rotating support, the gasket including a light transmission hole, in communication with the light transmission hole of the plurality of blades and the space of the rotating support (see Chen Fig. 1, item 1-102).
It would have been obvious to one having ordinary skill in the art at the time the invention was filed to provide a gasket like that in Chen in the device of Oh in order to provide further structural support for the rotating member and to aid in preventing unwanted light from reaching the image sensor.
Allowable Subject Matter
Claims 9-11 and 18 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.
