Office Action

§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 . Election/Restriction Claims 1, 4-7 and 9 remain for examination of which claims 1, 4-7 and 9 were amended in Applicant’s reply. Claim 10 remains withdrawn from further consideration pursuant to 37 CFR 1.142(b), as being drawn to a nonelected invention, there being no allowable generic or linking claim. Applicant timely traversed the restriction (election) requirement in the reply filed on 26 September 2025 (affirmed on 12/22/2025). 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. List 1 Element Instant Claims (mass%) Prior Art (mass%) C 0.18 – 0.28 0.07 – 0.25 Si ≤ 0.20 0.04 – 2 Mn 1.20 – 2.0 1.2 – 3 P 0.030 – 0.080 0.05 or less S ≤ 0.004 0.02 or less Al 0.02 – 0.06 0.01 – 2 Nb 0.02 – 0.06 0.2 or less Ti 0.025 – 0.045 0.2 or less V 0.05 – 0.15 0.2 or less Cr 0.5 – 2.5 1 or less Mo 0.10 – 0.30 1 or less B 0.0015 – 0.0035 0.1 or less N ≤ 0.005 - Fe + impurities Balance Balance Claims 1, 4-7 and 9 are rejected under 35 U.S.C. 103 as being unpatentable over JP 2015-014025 A of Fujinaka and its English machine translation (JP’025). Regarding claim 1, JP 2015-014025 A of Fujinaka and its English machine translation (JP’025) teaches {abstract, claims 1-6, [0001], [0015]-[0019], [0022]-[0036]} “a steel sheet blank using, as a raw material, a high-strength steel sheet for laser processing which has excellent elongation and stretch-flanging properties while having a high strength of 780 MPa or higher” with a composition wherein the claimed ranges of the constituent elements of the instant alloy of the instant claims overlap or lie inside the ranges of various elements of the alloy of the prior art as shown in the List 1 above. As the claimed ranges overlap or lie inside ranges disclosed by the prior art, a prima facie case of obviousness is established as it 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 to select the claimed composition over the prior art disclosure since the prior art teaches the similar property/utility throughout the disclosed ranges. In the case where the claimed ranges "overlap or lie inside ranges disclosed by the prior art" a prima facie case of obviousness exists. In re Wertheim, 541 F.2d 257, 191 USPQ 90 (CCPA 1976); In re Woodruff, 919 F.2d 1575, 16 USPQ2d 1934 (Fed. Cir. 1990); In re Geisler, 116 F.3d 1465, 1469-71, 43 USPQ2d 1362, 1365-66 (Fed. Cir. 1997). See MPEP § 2144.05 I. Regarding the amended limitation of the microstructure of instant claim 1, the prior art teaches “[0014] Furthermore, the base material portion excluding the cut end surface portion has a composite structure in which the ferrite area ratio is 10 to 80%, the retained austenite area ratio is 2% or more, and the balance is martensite and bainite.” thereby meeting the instant recited limitations. In the case where the claimed ranges "overlap or lie inside ranges disclosed by the prior art" a prima facie case of obviousness exists. In re Wertheim, 541 F.2d 257, 191 USPQ 90 (CCPA 1976); In re Woodruff, 919 F.2d 1575, 16 USPQ2d 1934 (Fed. Cir. 1990); In re Geisler, 116 F.3d 1465, 1469-71, 43 USPQ2d 1362, 1365-66 (Fed. Cir. 1997). See MPEP § 2144.05 I. Regarding the limitation of “for automobiles” in the preamble, the prior art teaches [0020] “The steel sheet blank and the steel sheet for laser cutting according to the present invention are ideal as materials for structural members used in automobiles and various industrial machines, in particular as materials for structural members such as automobile seat parts and suspension parts.” thereby meeting the instant limitation. Regarding claims 4 and 7, the prior art teaches [0001] “the present invention relates to a steel sheet blank having a high tensile strength of 780 MPa or more and good elongation” [0045] “Therefore, the tensile strength is set to 780 MPa or more. The tensile strength is preferably 980 MPa or more.” and points out via examples elongation values of 15-24% thereby meeting the instant recited limitations. In the case where the claimed ranges "overlap or lie inside ranges disclosed by the prior art" a prima facie case of obviousness exists. In re Wertheim, 541 F.2d 257, 191 USPQ 90 (CCPA 1976); In re Woodruff, 919 F.2d 1575, 16 USPQ2d 1934 (Fed. Cir. 1990); In re Geisler, 116 F.3d 1465, 1469-71, 43 USPQ2d 1362, 1365-66 (Fed. Cir. 1997). See MPEP § 2144.05 I. Regarding claims 5-6, the prior art is silent regarding its alloy having the properties and values of a) yield strength and b) oxidation resistance as recited in the instant claims. Where the claimed and prior art products are identical or substantially identical in structure or composition, or are produced by identical or substantially identical processes, a prima facie case of either anticipation or obviousness has been established. In re Best, 562 F.2d 1252, 1255, 195 USPQ 430, 433 (CCPA 1977). See MPEP § 2112.01 I. “Products of identical chemical composition can not have mutually exclusive properties.” A chemical composition and its properties are inseparable. Therefore, if the prior art teaches the identical chemical structure, the properties applicant discloses and/or claims are necessarily present. In re Spada, 911 F.2d 705, 709, 15 USPQ2d 1655, 1658 (Fed. Cir. 1990). See MPEP § 2112.01 II. Therefore, it is expected that the alloy of the prior art possesses the properties as claimed in the instant claims since a) the claimed and prior art products are identical or substantially identical in composition (see compositional analysis above), b) the claimed and prior art products are identical or substantially identical in structure (see microstructure analysis above) and c) the claimed and prior art products are produced by identical or substantially identical processes {instant alloy: instant specification [42]-[44]; Prior art: [0046]-[0061]}. Since the Office does not have a laboratory to test the reference alloy, it is applicant’s burden to show that the reference alloy does not possess the properties as claimed in the instant claims. See In re Best, 195 USPQ 430, 433 (CCPA 1977); In re Marosi, 218 USPQ 289, 292-293 (Fed. Cir. 1983); In re Fitzgerald et al., 205 USPQ 594 (CCPA 1980). Regarding claim 9, the prior art teaches [0019], [0022] “A method for manufacturing a steel sheet” “steel sheet” which would read on the instant recited thickness limitations as the definition or the thickness of steel sheet falls within the claimed ranges. Response to Arguments Applicant's arguments filed 12/22/2025 have been fully considered but they are not persuasive. With respect to the arguments that the embodiments provided by the prior art do not teach the claimed matter, the arguments have been fully considered but they are not persuasive. Patents are relevant as prior art for all they contain. "The use of patents as references is not limited to what the patentees describe as their own inventions or to the problems with which they are concerned. They are part of the literature of the art, relevant for all they contain." In re Heck, 699 F.2d 1331, 1332-33, 216 USPQ 1038, 1039 (Fed. Cir. 1983) (quoting In re Lemelson, 397 F.2d 1006, 1009, 158 USPQ 275, 277 (CCPA 1968)). Disclosed examples and preferred embodiments do not constitute a teaching away from a broader disclosure or nonpreferred embodiments. In re Susi, 440 F.2d 442, 169 USPQ 423 (CCPA 1971).See MPEP § 2123. Regarding the amended limitation of the microstructure of instant claim 1, the prior art teaches “[0014] Furthermore, the base material portion excluding the cut end surface portion has a composite structure in which the ferrite area ratio is 10 to 80%, the retained austenite area ratio is 2% or more, and the balance is martensite and bainite.” thereby meeting the instant recited limitations. In the case where the claimed ranges "overlap or lie inside ranges disclosed by the prior art" a prima facie case of obviousness exists. In re Wertheim, 541 F.2d 257, 191 USPQ 90 (CCPA 1976); In re Woodruff, 919 F.2d 1575, 16 USPQ2d 1934 (Fed. Cir. 1990); In re Geisler, 116 F.3d 1465, 1469-71, 43 USPQ2d 1362, 1365-66 (Fed. Cir. 1997). See MPEP § 2144.05 I. As noted above, the prior art renders the instant claims obvious. If a prima facie case of obviousness is established, the burden shifts to the applicant to come forward with arguments and/or evidence to rebut the prima facie case. See, e.g., In re Dillon, 919 F.2d 688, 692, 16 USPQ2d 1897, 1901 (Fed. Cir. 1990). Rebuttal evidence and arguments can be presented in the specification, In re Soni, 54 F.3d 746, 750, 34 USPQ2d 1684, 1687 (Fed. Cir. 1995), by counsel, In re Chu, 66 F.3d 292, 299, 36 USPQ2d 1089, 1094-95 (Fed. Cir. 1995), or by way of an affidavit or declaration under 37 CFR 1.132, e.g., Soni, 54 F.3d at 750, 34 USPQ2d at 1687; In re Piasecki, 745 F.2d 1468, 1474, 223 USPQ 785, 789-90 (Fed. Cir. 1984). However, arguments of counsel cannot take the place of factually supported objective evidence. See, e.g., In re Huang, 100 F.3d 135, 139-40, 40 USPQ2d 1685, 1689 (Fed. Cir. 1996); In re De Blauwe, 736 F.2d 699, 705, 222 USPQ 191, 196 (Fed. Cir. 1984). See MPEP § 2145. Attorney argument is not evidence unless it is an admission, in which case, an examiner may use the admission in making a rejection. See MPEP § 2129 and § 2144.03 for a discussion of admissions as prior art. The arguments of counsel cannot take the place of evidence in the record. In re Schulze, 346 F.2d 600, 602, 145 USPQ 716, 718 (CCPA 1965); In re Geisler, 116 F.3d 1465, 43 USPQ2d 1362 (Fed. Cir. 1997) ("An assertion of what seems to follow from common experience is just attorney argument and not the kind of factual evidence that is required to rebut a prima facie case of obviousness."). See MPEP § 716.01(c) for examples of attorney statements which are not evidence and which must be supported by an appropriate affidavit or declaration. See MPEP § 2145 I. Conclusion THIS ACTION IS MADE FINAL. 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.
