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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 04/23/2026 has been entered.
Status of Claims
Claims 1-12, 14-18, 22, 23, and 26 are pending. Claims 13, 19-21, 24, and 25 are cancelled.
Response to Arguments
Applicant's arguments filed a Request for Continued Examination (RCE) with an Information Disclosure Statement (IDS) on 04/23/2026. The references in the IDS have been considered. Applicant has not filed remarks or amendments to the pending claims, thus, the previous rejection remains. However, the rejection of claim 11 under 35 U.S.C 112 (a) or 35 U.S.C 112 (pre-AIA ), first paragraph has been reconsidered and the rejection is obviated by the original disclosure that states “Alternatively or additionally, VPLI (vapor permeable liquid impermeable) film may comprise a single-layer film that is a microporous film (para. 0047 published application US 2022/0378631), which provides support for the film materials claimed in claim 11.
The rejection of claims 1-4, 9-10, 14-18, 22, 23, and 26 under 35 U.S.C. 103 as being unpatentable over LaVon et al. USPN 5938648 and the rejection of claims 5-8 under 35 U.S.C. 103 as being unpatentable over LaVon in view of Collier, IV et al. US Patent Application Publication 2004/0224136 stands.
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.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
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.
Claims 1-4, 9-10, 14-18, 22, 23, and 26 are rejected under 35 U.S.C. 103 as being unpatentable over LaVon et al. USPN 5938648
As to claim 1, LaVon teaches a textile backsheet (TBS) 10 (LaVon Figures 1 and 2), comprising:
(i) a nonwoven fabric 14 (col. 5, lines 28-31; lines 50-56); and
(ii) a microporous film 12 (col. 10, line 60 through col. 11, line 8) that is vapor-permeable and liquid impermeable (col. 9, lines 65-67), wherein the nonwoven fabric is bonded to the microporous film via an adhesive layer (col. 7, lines 26-29; col. 11, lines 8-17);
wherein the TBS has:
(a) a basis weight from 10 grams-per-square-meter (gsm) to 20 gsm – where LaVon teaches an example of a nonwoven blend sheet material having a basis weight of 9.9 g/m2 to 28.3 g/m2 (col. 26, lines 21-23), which has values in the claimed range.
LaVon does not teach an abrasion resistance grade (“Grade”) of at least 3.0 as determined by SS-EN ISO 12945-2. However, when the structure or composition recited in the reference is substantially the same as that of the claims of the instant invention, claimed properties or functions are presumed to be inherent (MPEP 2112-2112.01). A prima facie case of either anticipation or obviousness has been established when the reference discloses all the limitations of a claim except for an abrasion resistance grade of having specific value of 3.0 as determined according to the claimed test method. The examiner cannot determine whether or not the reference inherently possesses properties that anticipate or render obvious the claimed invention but has a basis for shifting the burden of proof to the Applicant. In this case, LaVon discloses a backsheet comprising a breathable film of the claimed materials adhered to one or more nonwovens having the claimed basis weight where the composite web has moisture vapor transmission rates with the claimed values. Thus, one skilled in the art has reason to expect an abrasion resistance grade falling within the claimed range.
LaVon teaches the microporous film laminate film structure /substrate composite is a has a moisture vapor transmission rate (MVTR) comprising at least 4000 g/m2/24 hrs (LaVon col. 11, lines 9-16 and 62-67; col. 46, lines 37-42). LaVon does not teach the MVTR measured as determined according to NWSP 070.4.RO. However, the testing method for a material or structural property does not impart a patentable weight. The property is attributed to the material and structure, not the testing method. As such, a reference does not need to recite the specific test method to read on the claim limitation. Additionally, since LaVon teaches the materials and structure of the claimed invention, and obviously includes a backsheet composite that would achieve the claimed results when testing in same manner.
As to claim 2, the nonwoven fabric has a first basis weight from about 4 gsm to about 10 gsm - where LaVon teaches an example of a nonwoven blend sheet material having a basis weight of 9.9 g/m2 to 28.3 g/m2 (col. 26, lines 21-23; Table 4), which has values in the claimed range.
As to claim 3, the nonwoven fabric 14 comprises at least one spunbond layer, at least one meltblown layer, at least one carded layer, or any combinations thereof (LaVon col. 5, lines 50-56).
As to claim 4, LaVon teaches the nonwoven fabric 14, 16 comprises one or more spunbond layers – where LaVon teaches substrates 14 and 16 may be polyethylene spunbonded webs (LaVon Figure 2; col. 5, lines 50-56).
As to claim 9, LaVon teaches the microporous film comprises a thickness from 10 to 200 microns – where LaVon teaches laminating the substrates 14, 16 to a very thin film (<25 microns) (col. 6, lines 27-28; col. 7, lines 4-6, Table 4; col. 12, lines 5-14) and <25 microns has values in the claimed range of 10 to 200 microns.
As to claim 10, LaVon refers to the microporous film layer in terms of “a microporous film” (col. 10, lines 60-62), which suggests the film 12 comprises a single-layer film, unless otherwise noted.
As to claim 14, Lavon teaches the present invention substantially as claimed, but does not teach the TBS has a first ratio between a machine direction tensile strength (MDTS) at peak (N / 25 mm) and a basis weight of the TBS (gsm) from 1:1 to 1.5:1. LaVon teaches the backsheet has a tensile strength and a basis weight (LaVon Table 4). One having ordinary skill in the art would be able to determine through routine experimentation the tensile strength to basis weight ratio for desired breathability, conformability, and softness of the backsheet laminate.
As to claim 15, LaVon teaches that preferably a composite sheet material to be used as the backsheet in an absorbent article has an elongation of at least 30%, and more preferably of at least 50% in both machine and cross directions (col. 13, lines 35-44), which has values in the claimed range of from about 40% to about 100%. LaVon does not specifically teach the elongation at peak is determined by the ASTM D5035. However, the testing method for a material or structural property does not impart a patentable weight. The property is attributed to the material and structure, not the testing method. As such, a reference does not need to recite the specific test method to read on the claim limitation. Additionally, since LaVon teaches the materials and structure of the claimed invention, the reference obviously includes a backsheet composite that would achieve the claimed results when testing in same manner.
As to claim 16, LaVon teaches an absorbent article 250, comprising:
(i) a TBS 247 according to claim 1 (Figure 7; col. 34, lines 55 through col. 35, line 2; col. 37, lines 38-42);
(ii) a liquid permeable topsheet 249; and
(iii) an absorbent body 275 located between the TBS 247 and the liquid permeable topsheet 249.
As to claim 17, LaVon teaches the absorbent article 250 comprises a diaper (Figure 7; col. 37, lines 38-42).
As to claim 18, LaVon teaches a method of forming a textile backsheet (TBS), comprising:
(i) providing or forming a nonwoven fabric 14 (col. 5, lines 28-31; lines 50-56); and
(ii) providing for forming a microporous film 12 (col. 10, line 60 through col. 11, line 8), that is vapor-permeable and liquid impermeable (col. 9, lines 65-67)
(iii) bonding the nonwoven fabric to the film via an adhesive layer to form the TBS;
(col. 7, lines 26-29; col. 11, lines 8-17);
wherein the TBS has:
(a) a basis weight from 10 grams-per-square-meter (gsm) to 20 gsm – where LaVon teaches an example of a nonwoven blend sheet material having a basis weight of 9.9 g/m2 to 28.3 g/m2 (col. 26, lines 21-23), which has values in the claimed range.
LaVon does not teach an abrasion resistance grade (“Grade”) of at least 3.0 as determined by SS-EN ISO 12945-2. However, when the structure or composition recited in the reference is substantially the same as that of the claims of the instant invention, claimed properties or functions are presumed to be inherent (MPEP 2112-2112.01). A prima facie case of either anticipation or obviousness has been established when the reference discloses all the limitations of a claim except for an abrasion resistance grade of having specific value of 3.0 as determined according to the claimed test method. The examiner cannot determine whether or not the reference inherently possesses properties that anticipate or render obvious the claimed invention but has a basis for shifting the burden of proof to the Applicant. In this case, LaVon discloses a backsheet comprising a breathable film of the claimed materials adhered to one or more nonwovens having the claimed basis weight where the composite web has moisture vapor transmission rates with the claimed values. Thus, one skilled in the art has reason to expect an abrasion resistance grade falling within the claimed range.
LaVon teaches the microporous film laminate/nonwoven substrate composite has a moisture vapor transmission rate (MVTR) comprising at least 4000 g/m2/24 hrs (LaVon col. 11, lines 9-16 and 62-67; col. 46, lines 37-42). LaVon does not teach the MVTR measured as determined according to NWSP 070.4.RO. However, the testing method for a material or structural property does not impart a patentable weight. The property is attributed to the material and structure, not the testing method. As such, a reference does not need to recite the specific test method to read on the claim limitation. Additionally, since LaVon teaches the materials and structure of the claimed invention, Lavon obviously includes a backsheet composite that would achieve the claimed results when tested in same manner.
As to claim 22, LaVon teaches the nonwoven fabric 14, 16 comprises one or more spunbond layers comprising bi-component fibers (LaVon col. 6, lines 18-20).
As to claim 23, LaVon does not specifically teach the nonwoven fabric 14, 16 comprises one or more spunbond layers and one or more meltblown layers. However, LaVon does teach the selection of materials for a nonwoven web provide the desired softness and breathability and suitable materials for the nonwoven fabric includes spunbond webs, meltblown webs, carded webs and the like (col. 43, lines 37-39). It would have been obvious to one having ordinary skill in the art before the invention was originally filed to modify the composite with at least one spunbond and at least one meltblown layer since 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.
As to claim 26, the microporous film consists of one or more microporous film layers (LaVon col. 10, lines 60-62).
Claims 5-8 are rejected under 35 U.S.C. 103 as being unpatentable over LaVon as applied to claim 1 above in view of Collier, IV et al. US Patent Application Publication 2004/0224136.
As to claim 5, LaVon teaches the present invention substantially as claimed. LaVon does not teach the nonwoven fabric comprises a high-loft nonwoven fabric having a density of less than 60 kg/m*, a thickness comprising from 0.3 mm to 3 mm, or both. Collier teaches high loft low density nonwoven webs for use in absorbent articles where the laminate nonwoven fabrics may be given appropriate functionalities such as breathability and fluid barrier properties (Collier paragraph 0007). Collier teaches the nonwoven web including web laminates may particularly be utilized to obtain breathable liquid-barrier layers having a soft cloth-like feel for use in garment outer covers and the like (Collier paragraph 0024). It would have been obvious to one having ordinary sklll in the art before the invention was originally filed to modify the nonwoven of LaVon with the high loft nonwoven of Collier for the benefits taught in Collier.
Collier/LaVon teaches the lofty webs have a density range of from .04 to .0003 g/cc, which meets the claimed density of less than 60 kg/m3. Collier further teaches the nonwoven web has a bulk to about 0.1 inches in the Z axis (Collier paragraph 0011).
As to claim 6, LaVon/Collier teaches the nonwoven fabric comprises a first plurality of multi-component crimped fibers – where Collier teaches crimped bicomponent fibers for the high loft, low density nonwoven webs (paragraphs 0006, 0008-0009, ad 0018-0019).
As to claim 7, LaVon/Collier teach the multi-component crimped fibers comprise continuous fibers (Collier paragraph 0008).
As to claim 8, Lavon/Collier teach the multi-component crimped fibers comprise crimped continuous spunbond fibers (Collier paragraph 0008).
Claims 11 and 12 are rejected under 35 U.S.C. 103 as being unpatentable over LaVon as applied to claims 1 and 9 above, in view of Haffner et al. USPN 6045900.
As to claims 11 and 12, LaVon teaches the present invention substantially as claimed. LaVon teaches the microporous film comprises a multi-layer film (col. 10, line 60 through col. 11, line 16). LaVon does not teach the microporous film comprising at least a first skin layer and a core layer, wherein the first skin layer has a first thickness and the core layer has a second thickness, and the first thickness is less than the second thickness. Haffner teaches a breathable multilayer film for use as a barrier layer (Haffner col. 2, lines 53-60). Haffner teaches the film comprises multi-layer film 52 having a first skin layer 56a and a core layer 54 comprising a microporous film – where Haffner teaches the composition of the base film 54 corresponds to the breathable base layer 14 and the composition of the layers 56a and 56b can correspond to the layer 16 (Haffner col. 7, lines 29-35; col. 11, lines 27-43). The breathable base layer and the outer layers comprise at least one of a thermoplastic urethane, a polyether-block-amide copolymer, a polyether-block-ester copolymer, polyester- block-amide copolymer, or a copolyester thermoplastic elastomer (Haffner col. 7, line 49 through col. 9, line 4). Haffner further teaches the thickness of the outer layer 56a, 56b is less than the core of the film 54 (Haffner Fig. 2.) It would have been obvious to one having ordinary skill in the art to provide the multi-layer film of LaVon with the structure of the multi-layer film of Haffner since both are from the same field of endeavor and solve the same problem of providing barrier materials.
Double Patenting
The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969).
A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b).
The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13.
The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/apply/applying-online/eterminal-disclaimer.
Claims 1-12, 14-18, and 22-25 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims of copending Application No. 17/951,668. Although the claims 1-18 at issue are not identical, they are not patentably distinct from each other because the claims of the present invention contain each and every limitation of claims of the 17/951,668 application as well as additional features. The claims of the instant application are a broader recitation of the claims of the 17/951,668 application in that the ‘668 application does not set forth a specific moisture vapor transmission rate.
This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented.
