Office Action

§102 §103
Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . DETAILED ACTION Notice of Pre-AIA or AIA Status 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 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. Specification The title of the invention is not descriptive. A new title is required that is clearly indicative of the invention to which the claims are directed. Claim Interpretations In claim 1, the limitation “when a direction along an optical axis of the first lens is defined as an optical axis direction, the first lens is supported from the image side at a predetermined first position in the optical axis direction” appear to be a conditional claim. For examining purposes, the examiner assumes the second part of the phrase is no longer valid if a direction along an optical axis of the first lens is not defined as an optical axis direction. In claim 2, the limitation “when the fitting portion and the fitted portion are fitted to each other, the fitting-portion tapered surface and the fitted-portion tapered surface come into surface contact with each other” appear to be a conditional claim. For examining purposes, the examiner assumes the second part of the phrase is no longer valid if the fitting portion and the fitted portion are not fitted to each other Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate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)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale or otherwise available to the public before the effective filing date of the claimed invention. Claims 1-5 and 7-9 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Horiuchi et al. (US 2016/0349475). Regarding claim 1, Horiuchi et al. (figures 1-3B) discloses a lens unit comprising: a first lens and a second lens disposed in this order from an image side toward an object side (15 and 13); and a lens barrel (7) which accommodates the first lens and the second lens on an inner peripheral side, wherein the second lens includes a fitting portion (78 or 77) fitted to the first lens on a surface on the image side; when a direction along an optical axis of the first lens is defined as an optical axis direction, the first lens is supported from the image side at a predetermined first position in the optical axis direction; a fitted portion (77 or 78) to which the fitting portion is fitted from the object side is provided on a surface on the object side of the first lens; a first inner peripheral-surface portion located on an outer side in a radial direction of the first lens on the inner peripheral surface of the lens barrel includes first fitting protrusions which are pressure-joined to the first lens at a plurality of spots separated in a circumferential direction; a second inner peripheral-surface portion (735-738) located on the outer side in the radial direction of the second lens on the inner peripheral surface of the lens barrel includes guide protrusions which guide the second lens in the optical axis direction at a plurality of spots separated in the circumferential direction; a plurality of the first fitting protrusions (77-78; see at least paragraph 0063) position the first lens in the radial direction; and the first lens is positioned in the radial direction with respect to the second lens by fitting of the fitting portion and the fitted portion. “[E]ven though product-by-process claims are limited by and defined by the process, determination of patentability is based on the product itself. The patentability of a product does not depend on its method of production. If the product in the product-by-process claim is the same as or obvious from a product of the prior art, the claim is unpatentable even though the prior product was made by a different process.” In re Thorpe, 777 F.2d 695, 698, 227 USPQ 964, 966 (Fed. Cir. 1985). See MPEP §2113. Regarding claim 2, Horiuchi et al. (figures 1-3B) discloses wherein the fitting portion includes a fitting-portion tapered surface which surrounds the optical axis and is inclined to an inner peripheral side toward the image side; the fitted portion includes a fitted-portion tapered surface which surrounds the optical axis and is inclined to an outer peripheral side toward the object side (77 and 78; figure 3B); and when the fitting portion and the fitted portion are fitted to each other, the fitting-portion tapered surface and the fitted-portion tapered surface come into surface contact with each other. Regarding claim 3, Horiuchi et al. (figures 1-3B) discloses wherein a clearance is provided between the second lens and a plurality of the guide protrusions in a state in which the fitting portion and the fitted portion are fitted to each other (18 and 13; see at least abstract). Regarding claim 4, Horiuchi et al. (figures 1-3B) discloses wherein the lens barrel is made of a resin (7; see at least paragraph 0060); the first inner peripheral-surface portion is a tapered surface inclined to an outer peripheral side toward the object side; and the first fitting protrusion includes a pressure-joining surface parallel to the optical axis at an end on an inner peripheral side (portions of 77 or 78). “[E]ven though product-by-process claims are limited by and defined by the process, determination of patentability is based on the product itself. The patentability of a product does not depend on its method of production. If the product in the product-by-process claim is the same as or obvious from a product of the prior art, the claim is unpatentable even though the prior product was made by a different process.” In re Thorpe, 777 F.2d 695, 698, 227 USPQ 964, 966 (Fed. Cir. 1985). See MPEP §2113. Regarding claim 5, Horiuchi et al. (figures 1-3B) discloses wherein the second inner peripheral-surface portion is a tapered surface inclined to the outer peripheral side toward the object side; and the guide protrusion includes a guide surface parallel to the optical axis at an end on an inner peripheral side (77; figure 3B). Regarding claim 7, Horiuchi et al. (figures 1-3B) discloses wherein a clearance is provided between the second lens and a plurality of the guide protrusions in a state in which the fitting portion and the fitted portion are fitted to each other (18 and 13; see at least abstract). Regarding claim 8, Horiuchi et al. (figures 1-3B) discloses wherein the lens barrel is made of a resin (7; see at least paragraph 0060); the first inner peripheral-surface portion is a tapered surface inclined to an outer peripheral side toward the object side; and the first fitting protrusion includes a pressure-joining surface parallel to the optical axis at an end on an inner peripheral side (portions of 77 or 78). “[E]ven though product-by-process claims are limited by and defined by the process, determination of patentability is based on the product itself. The patentability of a product does not depend on its method of production. If the product in the product-by-process claim is the same as or obvious from a product of the prior art, the claim is unpatentable even though the prior product was made by a different process.” In re Thorpe, 777 F.2d 695, 698, 227 USPQ 964, 966 (Fed. Cir. 1985). See MPEP §2113. Regarding claim 9, Horiuchi et al. (figures 1-3B) discloses wherein the second inner peripheral-surface portion is a tapered surface inclined to the outer peripheral side toward the object side; and the guide protrusion includes a guide surface parallel to the optical axis at an end on an inner peripheral side (77; figure 3B). 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 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. Claims 6 and 10 are rejected under 35 U.S.C. 103 as being unpatentable over Horiuchi et al. in view of Hirata (WO 2018-207909). Regarding claim 6, Horiuchi et al. (figures 1-3B) discloses a third lens (12) disposed on the object side of the second lens; the lens barrel includes an annular caulking portion (739) which is bent to an inner peripheral side and is brought into contact with an outer peripheral-end portion of the third lens from the object side on an end part on the object side and a first stepped portion on an inner peripheral surface (figure 3B); the first stepped portion includes an annular seating surface facing the object side at a position overlapping the caulking portion when viewed from the optical axis direction and an annular wall surface extending from an end on an inner peripheral side of the annular seating surface to the image side (figure 3B); an outer peripheral-edge portion of the third lens is located between the caulking portion and the seating surface (739); the first lens is supported from the image side at a predetermined first position in the optical axis direction. However, Horiuchi et al. is silent regarding an O-ring. Hirata (figure 1) teaches a third lens (12) disposed on the object side of the second lens (20); and an O-ring (37) disposed between the second lens and the third lens, wherein the third lens and the O-ring are accommodated in the lens barrel (11); and the O-ring is compressed in the optical axis direction at a position adjacent to the annular wall surface in the radial direction and exerts an urging force to urge the third lens toward the object side and to urge the second lens toward the first lens. Therefore, 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 display device of Smith with The limitation, “the first lens is supported from the image side at a predetermined first position in the optical axis direction and exerts an urging force to urge the third lens toward the object side and to urge the second lens toward the first lens” is functional in nature. Such a functional limitation is only given patentable weight insofar as it imparts a structural limitation. Here, Hirata discloses the structural limitations required to perform the function as claimed. It is further noted that apparatus claims must be structurally distinguishable from the prior art and that the manner of operating the device does not differentiate the apparatus claim from the prior art (see e.g. MPEP 2114). In other words, the prior art need not perform the function, but must merely be capable of doing so. Regarding claim 10, Horiuchi et al. (figures 1-3B) discloses a third lens (12) disposed on the object side of the second lens; the lens barrel includes an annular caulking portion (739) which is bent to an inner peripheral side and is brought into contact with an outer peripheral-end portion of the third lens from the object side on an end part on the object side and a first stepped portion on an inner peripheral surface (figure 3B); the first stepped portion includes an annular seating surface facing the object side at a position overlapping the caulking portion when viewed from the optical axis direction and an annular wall surface extending from an end on an inner peripheral side of the annular seating surface to the image side (figure 3B); an outer peripheral-edge portion of the third lens is located between the caulking portion and the seating surface (739); the first lens is supported from the image side at a predetermined first position in the optical axis direction. However, Horiuchi et al. is silent regarding an O-ring. Hirata (figure 1) teaches a third lens (12) disposed on the object side of the second lens (20); and an O-ring (37) disposed between the second lens and the third lens, wherein the third lens and the O-ring are accommodated in the lens barrel (11); and the O-ring is compressed in the optical axis direction at a position adjacent to the annular wall surface in the radial direction and exerts an urging force to urge the third lens toward the object side and to urge the second lens toward the first lens. Therefore, 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 display device of Smith with The limitation, “the first lens is supported from the image side at a predetermined first position in the optical axis direction and exerts an urging force to urge the third lens toward the object side and to urge the second lens toward the first lens” is functional in nature.

It is further noted that apparatus claims must be structurally distinguishable from the prior art and that the manner of operating the device does not differentiate the apparatus claim from the prior art (see e.g. MPEP 2114). In other words, the prior art need not perform the function, but must merely be capable of doing so.
