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/Restrictions
Applicant’s election without traverse of Group III (claims 5-7) in the reply filed on 01/07/2026 is acknowledged.
Claims 1-4 and 9 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to nonelected inventions, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on 01/07/2026.
Claim Objections
Claim 5 is objected to because of the following informalities:
In the last line of claim 5, there should be a comma immediately after “longitudinal direction”.
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.
Claims 5-7 are rejected under 35 U.S.C. 103 as being unpatentable over Suzuki et al. (US 20180230566 A1; cited in prior office action).
Regarding claim 1, with regard to the claimed steel wire composition for ultrahigh strength spring, Suzuki teaches overlapping compositional ranges as follows for a high strength spring steel:
[0014] (1) Spring steel for suspension containing, by mass %:
[0015] C: 0.40 to 0.70%;
[0016] Si: 0.80 to 2.20%;
[0017] Mn: 0.05 to 1.50%;
[0018] Cr: 0.05 to 1.00%;
[0019] P: limited to 0.020% or less;
[0020] S: limited to 0.020% or less, and
[0021] a balance of Fe and unavoidable impurities.
In the case where the claimed ranges "overlap or lie inside ranges disclosed by the prior art" a prima facie case of obviousness exists (MPEP 2144.05 I.). Similarly, a prima facie case of obviousness exists where the claimed ranges or amounts do not overlap with the prior art but are merely close (MPEP 2144.05 I.).
With regard to the claimed tempered martensite being 90% or more, Suzuki teaches that the tempered martensite is 90% or more [0063].
With regard to the claimed “wherein a ratio of an area satisfying one or more of C>0.8%, Si>0.9%, Cr>0.8% and Mn>0.8%, in wt %, in an area of 1 mm2 of a center of a cross-section perpendicular to a longitudinal direction is 5% or less”, Suzuki does not explicitly teach this limitation, but does teach a similar composition and similar process to that in the instant invention, of:
hot rolling a wire rod [0036], which is analogous to the step in the instant invention of drawing a wire rod,
heating to a temperature of 950°C to 1150°C [0036], analogous to the step in the instant invention of heating at 900-1000°C within 10 seconds,
quenching [0037], which is analogous to the step in the instant invention of water cooling at high pressure
tempering at 350-550°C [0084] within 3 seconds (claim 10 of Suzuki), which is analogous to the step of tempering at 400-500°C within 10 seconds in the instant invention.
Once a reference teaching product appearing to be substantially identical is made the basis of a rejection, and the examiner presents evidence or reasoning to show inherency, the burden of production shifts to the applicant. "[T]he PTO can require an applicant to prove that the prior art products do not necessarily or inherently possess the characteristics of his [or her] claimed product. Whether the rejection is based on ‘inherency’ under 35 U.S.C. 102, on ‘prima facie obviousness’ under 35 U.S.C. 103, jointly or alternatively, the burden of proof is the same." The burden of proof is similar to that required with respect to product-by-process claims. (MPEP 2112 V).
Regarding claim 6, Suzuki is silent regarding the hardness, but as discussed in the rejection of claim 5 above, Suzuki teaches a similar composition and process of making. Once a reference teaching product appearing to be substantially identical is made the basis of a rejection, and the examiner presents evidence or reasoning to show inherency, the burden of production shifts to the applicant. "[T]he PTO can require an applicant to prove that the prior art products do not necessarily or inherently possess the characteristics of his [or her] claimed product. Whether the rejection is based on ‘inherency’ under 35 U.S.C. 102, on ‘prima facie obviousness’ under 35 U.S.C. 103, jointly or alternatively, the burden of proof is the same." The burden of proof is similar to that required with respect to product-by-process claims. (MPEP 2112 V).
Regarding claim 7, Suzuki teaches that the steel has a tensile strength of at least 1800 MPa [0045], [0064], at an area reduction ratio of 40% or more [0045]. In the case where the claimed ranges "overlap or lie inside ranges disclosed by the prior art" a prima facie case of obviousness exists (MPEP 2144.05 I.). Similarly, a prima facie case of obviousness exists where the claimed ranges or amounts do not overlap with the prior art but are merely close (MPEP 2144.05 I.).
