Claim Rejections - 35 U.S.C. 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
4. Claim 1 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Claim 1 recites “the major axis being inclined at a first angle relative to a rolling direction of the analysis target”. However it is not clear what is meant by “a first angle relative to a rolling direction of the analysis target”, since the metes and bounds of this very generic and broad claim recitation are not clear. Instant specification [0023] discloses “analysis of two-dimensional magnetic properties of an analysis target, such as a grain-oriented electrical steel sheet or non-oriented electrical steel sheet”. Therefore the claim should be amended to recite the same to avoid confusion about what “a rolling direction of the analysis target refers to” and clarify “a rolling direction of a grain-oriented electrical steel sheet or non-oriented electrical steel sheet”, commensurate with the disclosure in the specification. Appropriate correction to the claim language is required to bring clarity to the claim recitation.
Claim 1 recites “…….elliptical magnetization applied….”. However in practice, elliptical magnetization is not applied, but rather a rotating magnetic field is applied or a target object is subjected to a rotating magnetic field which results in an elliptical magnetization being produced/realized in the target object, and in general magnetic field is applied and magnetization is produced in the target object. Appropriate correction to the claim language is required to bring clarity to the claim recitation.
5. Claims 2-13 are rejected under 35 U.S.C. 112 (b) due to their dependency.
Allowable Subject Matter
6. Claims 1-13 are allowable subject to overcoming the 35 USC 112 rejections cited above.
In related art Inoue et al (US 2020/0373046 A1) teaches, A grain-oriented electrical steel sheet for a stacked transformer core. The steel sheet having a sheet thickness t, where t and an iron loss deterioration ratio obtained by subjecting the steel sheet under elliptic magnetization satisfy the following relations: (i) when t 0.20 mm, the iron loss deterioration ratio is 85% or less; (ii) when 0.20 mm<t<0.27 mm, the iron loss deterioration ratio is 80% or less; and (iii) when 0.27 mm≤t, the iron loss deterioration ratio is 75% or less. The iron loss deterioration ratio is calculated from ((W.sub.A−W.sub.B)/W.sub.B)×100, where W.sub.A is iron loss under 50 Hz elliptic magnetization of 1.7 T in a rolling direction and 1.0 T in a direction orthogonal to the rolling direction, and W.sub.B is iron loss under 50 Hz alternating magnetization of 1.7 T in the rolling direction.
Masuda et al (US 2022/0051840 A1 ) teaches, An iron core (1, 11, 31) for a stationary induction apparatus according to one embodiment is configured by laminating a plurality of electromagnetic steel plates (5, 16, 33). The electromagnetic steel plates are laminated so that joint parts (6, 17, 18, 32), at which the end portions of the electromagnetic steel plates abut one another, are disposed in a staggered manner; and the electromagnetic steel plates are provided with a magnetic domain fine differentiation processed part (7, 19, 34), which is located on the portion, of a surface of the end portion of each of the electromagnetic steel plates, lapped with the joint part of another electromagnetic steel plate, and which has been subjected to warping-derived magnetic domain fine differentiation.
Omura et al (US 2018/0119244 A1 ) teaches, Provided is a grain-oriented electrical steel sheet having an excellent noise property in an actual transformer. Magnetostrictive properties of the grain-oriented electrical steel sheet are set such that the number of acceleration/deceleration points that are present in the magnetostriction velocity level dλ/dt in one period of magnetostrictive vibration is 4 and the magnitude of velocity level change between adjacent velocity change points in an acceleration zone or deceleration zone of magnetostrictive vibration is 3.0×10.sup.−4 sec.sup.−1 or less.
Cited prior art neither individually nor in combination, fails to teach, anticipate or render obvious, “A data set generation method of acquiring two-dimensional magnetic properties for use in analyzing an electromagnetic field of an analysis target by taking magnetic field strength and magnetic flux density as vector quantities, the data set generation method comprising: measuring a first magnetic field strength vector generated in the analysis target in response to first elliptical magnetization applied clockwise along an ellipse having a major axis and a minor axis with a predetermined axis ratio, the major axis being inclined at a first angle relative to a rolling direction of the analysis target; measuring a second magnetic field strength vector generated in the analysis target in response to second elliptical magnetization applied counterclockwise along an ellipse having a major axis and a minor axis with the predetermined axis ratio, the major axis being inclined at a second angle relative to the rolling direction of the analysis target, the second angle being opposite in sign from the first angle; calculating a first average magnetic field strength vector by averaging the first magnetic field strength vector and the second magnetic field strength vector; calculating a first average magnetic flux density vector by averaging a first magnetic flux density vector corresponding to the first elliptical magnetization and a second magnetic flux density vector corresponding to the second elliptical magnetization; and generating a data set of the two-dimensional magnetic properties that associates the first average magnetic field strength vector and the first average magnetic flux density vector with the predetermined axis ratio and the first angle” (as recited in the independent claim 1).
Claims 2-13 are allowed due to their dependency on claim 1.
