DETAILED ACTION
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 .
Response to Amendments
This office action is responsive to the amendment filed on 07/24/2026. As directed by the amendment: claims 1, 6, 8, and 16-17 have been amended, claims 2-3 and 11 have been canceled, and new claims 146-150 have been added. Thus, claims 1, 4-10, 12-19, and 146-150 are presently pending in the application.
Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claims 147-148 rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Claims 147 and 148 recite the limitation "the distal end of the tie" in line 1. It is unclear whether the “the distal end of the tie" is the same distal end from claim 1, wherein a tie that extends to “a distal end connected to the support structure”.
For examination purposes, the “distal end” from claims 1, 147, and 148 is where the tie is connected to the support structure.
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.
Claims 1, 4-10, 12-19, and 146-149 are rejected under 35 U.S.C. 103 as being unpatentable over Eves (US 20180272095 A1) in view of Guney (WO 2010148453 A1).
Regarding claim 1, Eves discloses a patient interface (FIG. 3A Patient interface 3000 as set forth in [0237]) comprising:

Eves fails to explicitly disclose, wherein the portion is a “textile” portion.
However, Guney teaches, wherein the portion of a sealing structure is a “textile” portion (Guney: FIG. 114 The sealing structure and tie are comprised of a laminated foam/fabric (air tight) fascia 7012, a semi-rigid skeleton frame 7010, a silicone/TPE undercushion 7004, a foam portion 7006, and a fabric layer 7008 along the outer side of the foam portion, undercushion, skeleton frame, and fascia, and the inner side of the undercushion, skeleton frame, and fascia as set forth in [00324]; wherein the material of the tie is a unitary homogenous material interpreted under its broadest interpretation as meaning the material, in this case used for the sealing structure and tie, are formed together to form one piece).
Eves and Guney are both considered to be analogous to the claimed invention because they are in the same field of respiratory facemasks. Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have modified the sealing structure including the “portion” as well as the support structure of Eves to incorporate the material composition of the sealing structure of Guney and include, wherein the portion is a “textile” portion (Guney: FIG. 114 The sealing structure and tie are comprised of a laminated foam/fabric (air tight) fascia 7012, a semi-rigid skeleton frame 7010, a silicone/TPE undercushion 7004, a foam portion 7006, and a fabric layer 7008 along the outer side of the foam portion, undercushion, skeleton frame, and fascia, and the inner side of the undercushion, skeleton frame, and fascia as set forth in [00324]; wherein the material of the tie is a unitary homogenous material interpreted under its broadest interpretation as meaning the material, in this case used for the sealing structure and tie, are formed together to form one piece). Doing so would improve the durability of the portion and may improve comfort (smooth surface finish, soft to touch, etc.) and aesthetics (Guney: As set forth in [00318]).
Regarding claim 4, Eves as modified discloses the claimed invention substantially as claimed as set forth for claim 1 above.
Eves as modified by Guney further teaches the patient interface, wherein the tie and the sealing structure comprise a unitary structure formed from a homogeneous material (The tie and the sealing structure may comprise a unitary structure formed from a homogeneous material as set forth in [0075]; and further, Guney: FIG. 114 The sealing structure and tie are comprised of a laminated foam/fabric (air tight) fascia 7012, a semi-rigid skeleton frame 7010, a silicone/TPE undercushion 7004, a foam portion 7006, and a fabric layer 7008 along the outer side of the foam portion, undercushion, skeleton frame, and fascia, and the inner side of the undercushion, skeleton frame, and fascia as set forth in [00324]; wherein the material of the tie is a unitary homogenous material interpreted under its broadest interpretation as meaning the material, in this case used for the sealing structure and tie, are formed together to form one piece).
Regarding claim 5, Eves as modified discloses the claimed invention substantially as claimed as set forth for claim 4 above.
Eves as modified by Guney further teaches the patient interface, wherein the homogeneous material comprises a textile material (Guney: FIG. 114 Fabric layer 7008 as set forth in [00324]).
Regarding claim 6, Eves discloses the claimed invention substantially as claimed as set forth for claim 5 above.
Eves as modified by Guney further teaches the patient interface, wherein the homogeneous material comprises multiple layers, with at least one layer being a textile material (Guney: FIG. 114 The sealing structure and tie comprised of a laminated foam/fabric (air tight) fascia 7012, a semi-rigid skeleton frame 7010, a silicone/TPE undercushion 7004, a foam portion 7006, and a fabric layer 7008 along the outer side of the foam portion, undercushion, skeleton frame, and fascia, and the inner side of the undercushion, skeleton frame, and fascia as set forth in [00324]; A unitary homogenous material interpreted under its broadest interpretation as meaning the material, in this case used for the sealing structure and tie, are formed together to form one piece).
Regarding claim 7, Eves as modified discloses the claimed invention substantially as claimed as set forth for claim 6 above.
Eves as modified by Guney further teaches the patient interface, wherein at least one layer is air impermeable (Guney: FIG. 114 The sealing structure and tie comprised of a laminated foam/fabric (air tight) fascia 7012 and silicone/TPE undercushion 7004 as set forth in [00324]; set forth in as being air impermeable in Applicant specification [0329]).
Regarding claim 8, Eves as modified discloses the claimed invention substantially as claimed as set forth for claim 7 above.
Eves as modified by Guney further teaches the patient interface, wherein the at least one layer that is air-impermeable comprises at least one of silicone (Guney: FIG. 114 The sealing structure and tie comprised of a laminated foam/fabric (air tight) fascia 7012 and silicone/TPE undercushion 7004 as set forth in [00324]; set forth in as being air impermeable in Applicant specification [0329]).
Regarding claim 9, Eves as modified discloses the claimed invention substantially as claimed as set forth for claim 1 above.
Eves further discloses the patient interface, wherein the sealing structure comprises a sealing flap at an edge region (FIG. 4-5 Sealing flap 3125 that protrudes inwards towards an inner perimeter of the sealing structure 3100 having an unconnected edge as set forth in [0253] and [0075]), the sealing flap being shaped and positioned to seal at least against a side of the patient's nose in use (FIG. 4-5 The sealing flap 3125 may include a portion 3125a that is configured to form a seal against the sides of the nose above the nasal bones of the patient as set forth in [0253] and [0075]).
Regarding claim 10, Eves as modified discloses the claimed invention substantially as claimed as set forth for claim 9 above.
Eves further discloses the patient interface, wherein the sealing flap comprises a thin edge region that is thinner than adjacent regions of the sealing structure (As set forth in [0075]).
Regarding claim 12, Eves as modified discloses the claimed invention substantially as claimed as set forth for claim 1 above.
Eves fails to explicitly disclose wherein the tie extends contiguously from the sealing structure at an edge region such that the tie forms an extension of the sealing surface in reference to the embodiment of FIG. 4-5 and 7-7A.
However, Eves teaches, wherein the tie extends contiguously from the sealing structure at an edge region such that the tie forms an extension of the sealing surface in reference to the embodiment of FIG. 31K (FIG. 31K the tie 3110 extends contiguously from the sealing flap 3125 as set forth in [0322]).
Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have modified the embodiment of FIG. 4-5 and 7-7A to incorporate the teaching of the embodiment of FIG. 31K and include wherein the tie extends contiguously from the sealing structure at an edge region such that the tie forms an extension of the sealing surface in reference to the embodiment of FIG. 31K (FIG. 31K the tie 3110 extends contiguously from the sealing flap 3125 as set forth in [0322]). Doing so provides another possible configuration forming the tie structure of the sealing structure for the resistance of deformation and the prevention of blowout that may be more suitable to the user than other embodiments of the patient interface (As set forth in [0076] and 0275]).
Regarding claim 13, Eves as modified discloses the claimed invention substantially as claimed as set forth for claim 1 above.
Eves further discloses the patient interface, wherein the tie comprises an inner surface and the sealing structure comprises an interior surface, the inner surface of the tie being adjacent to and separated from the interior surface of the sealing structure (As set forth in [0075], as well as shown in annotated FIG. 5 below).

Regarding claim 149, Eves as modified discloses the claimed invention substantially as claimed as set forth for claim 1 above.
Eves as modified by Guney further teaches the patient interface, wherein the support structure is constructed from silicone (Guney: FIG. 114 The sealing structure and tie are comprised of a laminated foam/fabric (air tight) fascia 7012, a semi-rigid skeleton frame 7010, a silicone/TPE undercushion 7004, a foam portion 7006, and a fabric layer 7008 along the outer side of the foam portion, undercushion, skeleton frame, and fascia, and the inner side of the undercushion, skeleton frame, and fascia as set forth in [00324], as set forth above for claim 1, the sealing structure including the “portion” as well as the support structure of Eves is modified to incorporate the material composition of the sealing structure of Guney, which includes silicone, meaning that the support structure is constrcted partially of silicone).
Claim 150 is rejected under 35 U.S.C. 103 as being unpatentable over Eves (US 20180272095 A1) in view of Guney (WO 2010148453 A1) as applied to claim 149, in view of Romagnoli (US 20150335846 A1).
Regarding claim 150, Eves as modified discloses the claimed invention substantially as claimed as set forth for claim 149 above.
Eves as modified further discloses, wherein the plenum chamber is constructed from a plastic material (FIG. 3A Plenum chamber 3200 is constructed from transparent polycarbonate as set forth in [0344]; know by one ordinary skill in the art as a plastic material),
Eves as modified fails to explicitly disclose the support structure is overmolded onto the plastic material.
However, Romagnoli teaches, wherein a portion of the sealing structure can be attached to a portion of the plenum by the sealing structure being overmolded onto a portion of the plenum (Romagnoli: FIG. 11b The main body 3180 may be permanently (e.g., co-molded, overmolded) connected to the seal-forming structure 3200. In an example, the seal-forming structure 3200 is constructed of a relatively flexible or pliable material (e.g., silicone) and the main body 3180 is constructed of a relatively rigid material (e.g., polycarbonate as set forth in [0130]).
Eves and Romagnoli are both considered to be analogous to the claimed invention because they are in the same field of respiratory facemasks. Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have modified connection between the support structure and plenum chamber of Eves to incorporate the method of connection utilized by Romagnoli and include, wherein a portion of the sealing structure can be attached to a portion of the plenum by the sealing structure being overmolded onto a portion of the plenum (Romagnoli: FIG. 11b The main body 3180 may be permanently (e.g., co-molded, overmolded) connected to the seal-forming structure 3200. In an example, the seal-forming structure 3200 is constructed of a relatively flexible or pliable material (e.g., silicone) and the main body 3180 is constructed of a relatively rigid material (e.g., polycarbonate) as set forth in [0130]). In the case of Eves as modified, the portion of the sealing structure being the support structure connected to the plenum. Doing so provides a method in which the sealing structure portion of a mask can be attached to the plenum or frame portion of the mask known in the art (Romagnoli: As set forth in [0120])
Response to Arguments
Applicant's arguments filed 07/24/2026 have been fully considered but they are not persuasive.
New grounds of rejection are made above to address the amendments to the claims.
Applicant argues that the term textile does not appear anywhere in the rejection to claim 1, however, the fabric layer taught by Guney is the feature relied upon when considering the “portion” to be “textile”, which is clear given that a textile is a fabric and is further explained in the rejection for claim 1 above. How Eves as modified by Guney discloses a “textile portion comprises a free, inner edge that at least partly forms a hole through which the flow of air is delivered to at least the entrance to the patient's nares” and “a distal end connected to the support structure or an inner surface of the textile portion opposite the sealing surface” are also set forth above in the rejection for claim 1. Additionally, it is noted that the definition of an edge used is "the outside limit of an object, area, or surface; a
place or part farthest away from the center of something" which the Examiner believes is consistent with what would be interpreted as the "edge" of the textile portion of Eves as modified by Guney set forth above.
Conclusion
Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
