Office Action

§112
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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 03/19/2026 has been entered. Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claims 1-2, 5-10 and 14-26 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. The added material which is not supported by the original disclosure is as follows: as to claim 1: “at least one bicomponent fiber comprising a core surrounded by a sheath and having a first melting point; and a second fiber having a second melting point, wherein the second melting point is at least about 15 0C higher than the first melting point”. As best understood, Applicant attempts to incorporate the claim subject matter of claim 13 into claim 1, however, the scope of claim 1 has been changed and hence support the claim 1 is missing for the following reasons: (a) previously recited claim 13 recites: “wherein the at least one non-thermally bondable fiber has a first melting and the thermally bondable fiber has a second melting point, wherein the first melting point is at least about 15 °C higher than the thermally bondable fiber”. (b) in previously presented claim 13, “the at least one non-thermally bondable fiber has a first melting point”, however, in currently amended claim 1, the second layer thermally bonded comprises the first melting point as set forth in claim 1. c. in addition, previously presented claim 13 recites:” the thermally bondable fiber has a second melting point” which is opposite of what is claimed in currently amended claim 1. Furthermore, as to claim 1, “a second fiber” is not supported in the original filed specification. In the original filed specification para [00106] states “In embodiments, the method further comprises providing at least one non-thermally bondable fiber within the second or fiber layer. The non-thermally bondable fiber has a melting point that is at least about 15 ºC higher than the melting point of the thermally bondable fiber. The non-thermally bondable fiber may comprise a bicomponent fiber”; which is different from what is claimed in currently amended claim 1. The original filed disclosure does not provide evidence that Applicant possessed these claim limitations at the time the application was filed. An objective standard for determining compliance with the written description requirement is, “does the description clearly allow persons of ordinary skill in the art to recognize that he or she invented what is claimed.” In reGosteli, 872 F.2d 1008, 1012, 10 USPQ2d 1614, 1618 (Fed. Cir. 1989). Under Vas-Cath, Inc.v. Mahurkar, 935 F.2d 1555, 1563-64, 19 USPQ2d 1111, 1117 (Fed. Cir. 1991), to satisfy the written description requirement, an applicant must convey with reasonable clarity to those skilled in the art that, as of the filing date sought, he or she was in possession of the invention, and that the invention, in that context, is whatever is now claimed. The test for sufficiency of support in a parent application is whether the disclosure of the application relied upon “reasonably conveys to the artisan that the inventor had possession at that time of the later claimed subject matter.” Ralston Purina Co.v.Far-Mar-Co., Inc., 772 F.2d 1570, 1575, 227 USPQ 177, 179 (Fed. Cir. 1985) (quoting In reKaslow, 707 F.2d 1366, 1375, 217 USPQ 1089, 1096 (Fed. Cir. 1983)). When filing an amendment an applicant should show support in the original disclosure for new or amended claims. See MPEP § 714.02 and § 2163.06. Claims 2, 5-10 and 14-26 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement since they depend directly or indirectly on rejected base claim 1 and therefore, contain the same deficiencies. Response to Arguments Applicant’s arguments, see pages 1-4, filed 03/19/2026, with respect to claims 1-2 and 5-26 have been fully considered and are persuasive. The rejection of claims 1-2 and 5-26 has been withdrawn.
