Office Action

§102 §103
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 . Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 04/29/2026 has been entered. Claims 1, 9, 17, and 23 have been amended, and claims 1-14, 17, and 19-23 remain pending in this application. 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 text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action. Claim(s) 9-14, 17, 19, and 20-23 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Issler (US 2010/0319214). Regarding claim 9, Issler discloses a footwear product comprising: at least one bladder (60); wherein the at least one bladder comprises a plurality of chambers (62, 64, 66), a top surface and a bottom surface; wherein the plurality of chambers are located in between the top surface and the bottom surface (Fig. 2); and wherein the at least one bladder comprises a liner (wherein the bladder may be placed on top of footbed 106 or act as the sole insole/liner: paragraph 0145; Fig. 7); wherein the top and bottom surface comprise at least six areas (for example: a toe area, a forefoot area, a front arch area, a rear arch area, a front heel area, and a rear heel area); wherein physical characteristics of the least six areas are different from each other (wherein the chambers may be made of different materials, for example rubber, cloth, or canvas: paragraph 0052; and wherein the areas each have different physical shapes) wherein at least one of the plurality of chambers is filled with at least one filler (72, 74, 76); wherein the top surface comprises at least two functional outer surfaces (wherein the chambers may be made of different materials, for example rubber, cloth, or canvas; paragraph 0052) which are separate from one another and wherein the bottom surface comprises at least two functional outer surfaces (wherein the chambers may be made of different materials, for example rubber, cloth, or canvas; paragraph 0052) which are separate from one another; wherein the at least one bladder further comprises at least one baffle (90) which controls flow of the at least one filler (paragraphs 0039-0041, 0046-0048, 0052; Fig. 1-6c). Regarding claim 10, Issler discloses that the at least one bladder is reversibly placeable inside the footwear (wherein the bladder is loose and capable of being reversibly placed). Regarding claim 11, Issler discloses that the at least one bladder comprises a longitudinal axis, and wherein the at least one baffle is placed at an angle relative to the longitudinal axis (paragraph 0047; Fig. 4a). Regarding claim 12, Issler discloses that the at least one bladder further comprising multiple baffles which are at different angles from one another (paragraph 0047; Fig. 4a). Regarding claim 13, Issler discloses that the at least one baffle is a permeable membrane (paragraph 0048; Fig. 5a-5d). Regarding claim 14, Issler discloses an upper (50), at least one footbed (106), an outsole (108) and at least one spacer (110) (paragraph 0145; Fig. 7). Regarding claim 17, Issler discloses a footwear product comprising: a sole (108); an upper (50); a bladder (60); wherein the bladder is filled with at least one filler (72, 74, 76); wherein the bladder comprising a top and a bottom; wherein the top comprises at least two functional outer surfaces which are separate from one another (wherein the chambers of the bladder may be made of different materials, for example rubber, cloth, or canvas; paragraph 0052); wherein the bottom comprises at least two functional outer surfaces which are separate from one another (wherein the chambers of the bladder may be made of different materials, for example rubber, cloth, or canvas; paragraph 0052); wherein all of the functional outer surfaces have physical characteristics different from each other (wherein the surfaces may be made of different materials and have different shapes); wherein the bladder has a profile analogous with a shape of a foot of a wearer (Fig. 1, 7) and is configured to be oriented with either the top in contact with a foot of a wearer or the top in contact with a footbed of the footwear; wherein the bladder is reversibly placeable on the footbed (wherein the bladder is capable of being oriented with either side facing upwards or downwards); wherein the bladder further comprises at least one baffle (90) which controls flow of the at least one filler (paragraphs 0039-0041, 0046-0048, 0052; Fig. 1-6c). Regarding claim 19, Issler discloses that the bladder further comprises ridges and/or grooves (grooves between chambers; Fig. 6a-6c). Regarding claim 20, Issler discloses that the at least one baffle is a permeable membrane (paragraph 0048; Fig. 5a-5d). Regarding claim 21, Issler discloses that the at least one bladder further comprises ridges and/or grooves (grooves between chambers; Fig. 6a-6c). Regarding claim 22, Issler discloses that the bladder further comprising multiple baffles which are at different angles from one another (paragraph 0047; Fig. 4a). Regarding claim 23, Issler discloses an upper (50), at least one footbed (106), an outsole (108) and at least one spacer (110) (paragraph 0145; Fig. 7). Claim Rejections - 35 USC § 103 The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action. Claim(s) 1-8 is/are rejected under 35 U.S.C. 103 as being unpatentable over Issler (US 2010/0319214) in view of Celia (US 7,908,772). Regarding claim 1, Issler discloses a footwear product comprising: a bladder (60) which is removably and reversibly placeable inside the footwear (wherein the bladder is loose and capable of being reversibly placed); wherein the bladder further comprises a top and a bottom; wherein the bladder further comprises at least a first and a second chamber (62, 64, 66) in between the top and the bottom; wherein the first chamber is filled with a first filler (72); wherein the second chamber is filled with a second filler (74); wherein the top comprises at least a first and a second functional outer surfaces (wherein the chambers may be made of different materials, for example rubber, cloth, or canvas; paragraph 0052); wherein the bottom comprises at least a first and a second functional outer surfaces (wherein the chambers may be made of different materials, for example rubber, cloth, or canvas; paragraph 0052); wherein all of the functional outer surfaces have physical characteristics different from each other (wherein the surfaces may be made of different materials and have different shapes); wherein at least one of bladders is generally asymmetrical about a longitudinal axis (Fig. 6b); wherein at least one of the plurality of bladders fits in and compatible to be used as a liner in both a left shoe and a right shoe (wherein the bladder is capable of being oriented with either side facing upwards or downwards, in either a right shoe or a left shoe); wherein at least one of the chambers comprises at least one baffle (90) which controls flow of at least one of the fillers (paragraphs 0039-0041, 0046-0048, 0052; Fig. 1-6c). Issler does not disclose a plurality of bladders. Celia teaches a footwear product with a plurality of inserts (footbeds 36), each insert having different physical characteristics (column 4, lines 30-57). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to provide a plurality of bladders, as taught by Celia, in order to allow a user to select the insert/bladder which best matches their needs. Regarding claim 2, Issler discloses that the first filler and the second filler have different densities (paragraph 0043). Regarding claim 3, Issler discloses that the at least one baffle is a permeable membrane (paragraph 0048; Fig. 5a-5d). Regarding claim 4, Issler discloses that at least one of the functional outer surfaces may be cloth (paragraph 0052), but does not specifically disclose a non-woven fiber. Celia teaches that an insert functional surface may include a non-woven fiber (column 9, lines 25-35). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to make at least one of the functional surfaces a non-woven fiber, as taught by Celia, in order to use a material well known in the art for shoe inserts, which provides strength, moisture wicking, and comfort to the foot. It further would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to use a non-woven fiber having a hardness of approximately 0-70 measured on the Shore durometer Scale O in order to use a material providing sufficient support and durability. It has been held to be within the general skill of a worker in the art to select a known material on the basis of its suitability for the intended use as a matter of obvious design choice. In re Leshin, 125 USPQ 416. Regarding claim 5, Issler discloses that the at least one of the plurality of bladders further comprises an arch support (Fig. 6a-6b). Regarding claim 6, Issler discloses the at least one of the plurality of bladders further comprises an affixing mechanism (stitching) which affixes the at least one of the plurality of bladders with the footwear (paragraph 0148; Fig. 10). Regarding claim 7, Issler does not disclose a bactericide. Celia teaches that a footwear insert (footbed) may include a bactericide or odor reducing property (column 6, lines 1-31). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have provided a bactericide, as taught by Celia, to one of the functional outer surfaces of Issler in order to reduce odor within the footwear element. Regarding claim 8, Issler discloses that the at least one of the plurality of bladders further comprises a third chamber (66) filled with a third filler (76), a third functional outer surface on the top, and a third functional outer surface on the bottom. Response to Arguments Applicant's arguments filed 03/30/2026 have been fully considered but they are not persuasive. Regarding claim 9, Applicant argues that the prior art does not disclose the top and bottom surfaces comprising at least six areas with each area having different physical characteristics. However, inasmuch as Applicant has defined different physical characteristics within the claims, Issler does disclose six different areas having different physical characteristics, including different materials and different physical shapes (see rejection of claim 9 above). Regarding claim 17, Applicant argues that the prior art does not disclose the bladder being reversibly placeable on the footbed. However, the bladder of Issler is capable of being placed with either side up on the footbed (see rejection of claim 17 above). Regarding claim 1, Applicant argues that the prior art does not disclose at least one of the bladders being asymmetrical about a longitudinal axis. However, Issler does disclose this limitation, as clearly shown in Fig. 6b. Applicant further argues that the prior art does not disclose the bladder fitting in and being compatible to be used as a liner in both a left shoe and a right shoe. However, the bladder is shaped such that it is capable of being oriented with either side facing upwards or downwards, in either a right shoe or a left shoe (see rejection of claim 1 above).
