Office Action

§103
DETAILED ACTION Summary The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Applicant’s arguments and claim amendments submitted on January 9, 2026 are entered into the file. Currently claim 1 is amended, resulting in claims 1-5 pending for examination. Claim Objections Claims 1-4 are objected to because of the following informalities: in claims 1-4 the Wt1/3, Tt1/2, Wy1/3, and Ty1/2 in Formulas (1-1), (1-2), (2-1), and (2-2) should read Wt1/3, Tt1/2, Wy1/3, and Ty1/2. Additionally “constructionmembrane” in line 14 of claim 1 should read –construction membrane--. Appropriate correction is required. 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. Claim(s) 1-5 is/are rejected under 35 U.S.C. 103 as being unpatentable over Brandel (US 2005/0130534) in view of Nonaka (US 2013/0210602). With respect to claims 1-4, Brandel teaches a glass fiber textile fabric which is aesthetically pleasing and fibers particular applicability as a fabric for wall coverings (construction membrane material) (paragraph [0002]). The warp yarn used in the woven, patterned glass fiber textile has a titer in the range of 155-300 tex, preferably 270-290 tex, most preferably about 278 tex (Tt) (paragraph [0012]). The weft yarn used together with the warp yarn can have a titer in the range of from 68 to 660 tex, preferably 190-350 tex, Most preferably 200-330 tex (Ty) (paragraph [0013]). It is noted that a 1 tex = 1 g/1000 m. The warp density (Wt) generally ranges from 2.5 to 20 threads/cm (6.25-50 threads/25 mm), preferably in the range of 6-10 threads/cm (15-25 threads/25 mm), with 6.5 threads/cm (16.25 threads/25 mm) being the most preferred (paragraph [0012]). The weft yarn density (Wy) ranges from 2.0 to 12 threads/cm (5-30 threads/25 mm), and is more preferably about 2.4 threads/cm (6 threads/25 mm) or 5.0 threads/cm (12.5 threads/25 mm) (paragraph [0013]). Brandel is silent as to the warp and weft glass fibers having an average Al2O3 content of 17.5 mass% or more. Nonoka teaches high elasticity glass fibers with an Al2O3 (At and Ay) content of 19.0-23.0 (paragraphs [0001], [0008]). When the Al2O3 content is 19.0% by weight or higher the elastic modulus of the glass fiber is raised (paragraph [0021]). On the other hand, when the content is 23.0% by weight or lower, the working temperature range of the glass is broadened (paragraph [0021]). The Al2O3 content is preferably 19.5 to 22.0% by weight, and more preferably 20.0 to 21.0% by weight based on the total weight of the composition of the glass fiber (paragraph [0021]). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the warp and weft glass fibers of Brandel to have an Al2O3 content of 19.0-23.0, preferably 19.5-22.0, more preferably 20.0-21.0% by weight of the glass fiber composition in order to provide a glass fiber with improved elastic modulus and workability. The most preferred value for Tt/Ty for the combination above is therefore 0.842-1.39 (278 tex/200-330 tex). This results in preferred values for formulas (1-1) and (1-2) ranging from 375 (when Ty = 200 tex and At = Ay = 20 wt%) to 422 (when Ty = 330 tex and At = Ay = 20 wt%). The preferred values for formulas (2-1) and (2-2) consequently range from 355 (when Ty = 330 tex, Tt/Ty = 0.842, and At = Ay = 20 wt%) to 521 (when Ty = 200 tex, Tt/Ty = 1.39, and At = Ay = 20 wt%). The values for formula (2-2) ranges of Brandel in view of Nonoka substantially overlaps the claimed ranges in the instant claim 4. It has been held that obviousness exists where the claimed ranges overlap or lie inside ranges disclosed by the prior art. See MPEP 2144.05 (I). Therefore, it would have been obvious to one of ordinary skill in the art at the time of the invention to have selected from the overlapping portion of the range taught by Brandel in view of Nonoka, because overlapping ranges have been held to establish prima facie obviousness. With respect to claim 5, Brandel in view of Nonoka teaches all the limitations of claim 1 above. Brandel further teaches the glass fiber textile may be coated in a conventional fashion to provide the final characteristics of the product (paragraph [0017]). Brandel does not explicitly teach the coating is applied to both the front and back surfaces of the fabric, however it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to try coating the front, the back, and the front and the back of the glass fabric in order to determine which provides the desired final characteristics to the product. See MPEP 2143. Response to Amendment Response – Claim Rejections 35 USC §103 The rejections of claim(s) 1-5 under 35 U.S.C. 103 as being unpatentable over Degroote (US 2004/0115439) have been withdrawn in light of the amendments to the claims in the response filed January 9, 2026. Applicant’s arguments with respect to claim(s) 1-5 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. 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). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
