Office Action

§102 §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/Restrictions Applicant's election with traverse of group 1 and species 1 in the reply filed on 08/17/26 is acknowledged. The traversal is on the ground(s) that the identified inventions pertain to a generic invention and are not mutually exclusive, and it would impose no undue burden to search and examine the claims corresponding to all of the identified inventions. . This is not found persuasive because as previously mentioned in the most recent office action, the inventions have acquired a separate status in the art in view of their different classification; also the inventions require a different field of search (for example, searching different classes/subclasses or electronic resources, or employing different search queries) and the figures to the different species recite mutually exclusive characteristics of such species which are not obvious variants of each other resulting in a serious search burden if a restriction was not implemented. Also claim 7 is withdrawn from consideration since the limitations about a third aperture reads on species 2 or 3 and not species 1 (figures 2a/4a). The requirement is still deemed proper and is therefore made FINAL. Claim Rejections - 35 USC § 102 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 the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. 1 Claims 1, 3-4 and 6 are rejected under 35 U.S.C. 102a1 as being anticipated by Erturk et al.

Regarding claim 3, Shen et al. (Col 3,lines 60-67) discloses wherein the magnetic conductor contains at least one of iron, nickel, cobalt, manganese, zinc or a combination thereof, or an alloy material of a combination thereof, including nickel/iron alloy, cobalt/nickel/iron alloy or zinc/nickel alloy. Regarding claim 4, Shen et al. (figure 3) discloses wherein the magnetic conductive layer is in a shape of a plane plate. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. 3 Claims 1, 3-4 and 6 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Feng et al. (US 2024/0312693). Regarding claim 1, Feng et al. (figures 1-10 and para 0048-0090) discloses a core body (10) having a first side and a second side opposing the first side (see figure 4) and a first aperture and a second aperture communicating with the first and the second side (see figure 4 and para 0048) and a magnetic conductor (3)(see para 0051) embedded in the core body and configured with respect to the first aperture and the second aperture of the core body (see figures 4-8), wherein the first aperture and the second aperture of the core body are formed on opposite sides of the magnetic conductor (see figure 4), wherein the magnetic conductor includes at least one magnetic conductive layer(see figures 5-8). Regarding claim 3, Feng et al (para 0051) discloses wherein the magnetic conductor contains at least one of iron, nickel, cobalt, manganese, zinc or a combination thereof, or an alloy material of a combination thereof, including nickel/iron alloy, cobalt/nickel/iron alloy or zinc/nickel alloy. Regarding claim 4, Feng et al.. (figures 2-10) discloses wherein the magnetic conductive layer is in a shape of a plane plate. Regarding claim 6, Feng et al. (figure 2) discloses wherein a top view shape of the magnetic conductive layer is a rectangular structure, a ring structure or a structure with a plurality of parallel slots in a rectangular outline. 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. 4 Claim 2 is rejected under 35 U.S.C. 103 as being unpatentable over Erturk et al. (US 20160163443) in view of Gozu et al. (US 20180061765). Regarding claim 2, Erturk et al.
