PNG media_image3.png 363 541 media_image3.png Greyscale With respect to claim 2, Yamada discloses the nose cover portion (48) is connected to the mask main body (46) only at a lower end of the nose cover portion (48, as shown in fig.17) in a state where the nose cover portion is unfolded with respect to the mask main body at the boundary (as shown in the reproduced image of fig.17 above). With respect to claim 5, Yamada discloses a mark indicating the boundary [the nose pad is attached at the boundary via stitching ([Page 9], 7th para]. With respect to claim 6, Yamada discloses at least a part of the boundary [where the stitching is located] has different rigidity [the threads the stitches are made from will have a different rigidity from the material the main body and nose cover portion is made from] from that of at least one of a portion of the mask main body (46) adjacent to the boundary and a portion of the nose cover portion (48) adjacent to the boundary. Claim(s) 7-8 and 10-11 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Berke U.S. Patent No. (7, 077, 140 B1). With respect to claim 7, Berke discloses a mask (as shown in fig.7) comprising: a mask main body (15, fig.7) for preventing exposure of a mouth of a user; and a nose cover or noseform (11) attached to a front side of the mask main body (as shown in fig.7) and ([Col.3], lines 28-32, the adhesive 12 or Velcro.RTM. (not shown) on the outer surface of the noseform 11 to an upper portion of the front or rear surface of the mask 15 before the mask is mounted on the person) so as to protrude from the mask main body in order to prevent exposure of an external nostril of the user (as shown in phantom in fig.6, during use), wherein the nose cover or noseform (11) is detachably attached to the mask main body via hook and loop fastener ([Col.3], lines 28-32, Velcro.RTM). attached to the front side of the mask main body. With respect to claim 8, Berke discloses a nose cover or noseform (11) attached to a front side of a mask main body (as shown in fig.7) and ([Col.3], lines 28-32, the adhesive 12 or Velcro.RTM.

With respect to claim 11, Berke discloses the nose cover or noseform (11) is attached to the mask main body with a hook-and-loop fastener ([Col.3], lines 28-32, Velcro.RTM). 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. Claim(s) 9 and 12 are rejected under 35 U.S.C. 103 as being unpatentable over Berke as applied to claims 8 and 7 above, and further in view of Samuel (U.S. Publication No. 2022/0225700 A1). With respect to claim 9, Berke substantially discloses the invention as claimed except the nose cover includes a clip for attaching the nose cover to the mask main body. Samuel however, teaches a face mask for protecting people from spreading infectious diseases (abstract) comprising a panel (130) to which connectors are hereby contemplated, including, but not limited to, hook and loop fastener, such as a Velcro® fastener, as shown in FIG. 1C, a button, a clip, etc. [0016] for connecting the panel to the face mask. In view of the teachings of Samuel, it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the fastener for attaching the nose cover to the mask main body of Berke by incorporating a clip for detachably for attaching the nose cover to the mask main body. With respect to claim 12, Berke substantially discloses the invention as claimed except the nose cover includes a clip for attaching the nose cover to the mask main body. Samuel however, teaches a face mask for protecting people from spreading infectious diseases (abstract) comprising a panel (130) to which connectors are hereby contemplated, including, but not limited to, hook and loop fastener, such as a Velcro® fastener, as shown in FIG. 1C, a button, a clip, etc. [0016] for connecting the panel to the face mask. In view of the teachings of Samuel, it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the fastener for attaching the nose cover to the mask main body of Berke by incorporating a clip for detachably for attaching the nose cover to the mask main body. Response to Arguments Applicant's arguments filed 07/11/2025 have been fully considered but they are not persuasive. Applicant argues as to claim 1, prior art references drawn to Liang and Yamada does not teach or suggests “the mask has a usage mode (abstract) in which the mask is attached to the head in a state where the nose cover portion is capable of being folded to a front side of the mask main body at the boundary as the usage mode in which the mask is attached to the head in a state where the nose cover portion is folded with respect to the mask main body at the boundary”; however, as to Laing suggests the whole mask ventilation, can contact with the nose bridge and improve the user wearing comfort pad is folded, the user can according to the use environment determining whether the pad is folded to improve comfort ([Page 2], 5th paragraph). The claim does not require a specific structural or manipulative difference from the prior art; a recitation of the intended use of the claimed invention must result in a structural difference between the claimed invention and the prior art in order to patentably distinguish the claimed invention from the prior art. If the prior art structure is capable of performing the intended use, then it meets the claim. Furthermore, the proposed modification would not render the invention unsatisfactory for its intended purpose. Furthermore, as to Yamada, the claim does not require a specific structural or manipulative difference from the prior art; a recitation of the intended use of the claimed invention must result in a structural difference between the claimed invention and the prior art in order to patentably distinguish the claimed invention from the prior art. If the prior art structure is capable of performing the intended use, then it meets the claim. Furthermore, the proposed modification would not render the invention unsatisfactory for its intended purpose. As to the prior art drawn to Seo, Applicant argues whether the drawings as presented by the prior art drawn to Seo indeed shows the nose cover attach to the front side of the mask main body as it is not clearly shown or explicitly disclosed have been fully considered and are persuasive. The prior art has been withdrawn, however, upon further consideration, a new ground(s) of rejection is made in view of Berke.
