Office Action

§102 §103 §112
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 . Specification The lengthy specification has not been checked to the extent necessary to determine the presence of all possible minor errors. Applicant’s cooperation is requested in correcting any errors of which applicant may become aware in the specification. Claim Objections Claim 1 is objected to because of the following informalities: Claim 1, line 1, "for diagnostic evaluation" should read --for a diagnostic evaluation--. Claim 1, line 3, "walls, a wall" should read -- walls, wherein a wall--. Claim 1, line 5, "components configured" should read --components is configured--. Appropriate correction is required. Claim Rejections - 35 USC § 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. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 4 and 5 are 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. Claims 4 and 5, line 1, it is unclear if the limitation "the wall" refers to the firstly recited "a wall" in claim 1. Examiner suggests to amend to "at least one of the plurality of walls". Claim 5, line 2, “or a mumetal is built around a nonmagnetic frame” is unclear as it raises the question if the limitation “is built around a non magnetic frame” applies to just a mumetal or both a permalloy and a mumetal. 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. Claims 1 – 2, 4 – 5, 12 and 14 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Shibuya (US 20190368191 A1). Regarding claim 1, Shibuya teaches a shielded chamber system for diagnostic evaluation of a condition of an individual (Figures 1 - 8; [0025]), comprising: a. an enclosure (“shielded room 1” [0025] Figures 1 - 8) comprising a plurality of walls (“an upper shielding body 11, a side periphery shielding body 12, a lower shielding body 13” [0025] Figures 1 - 8), a wall comprising a plurality of layers of magnetic shielding material (“permalloy plates 61, aluminum plates 62 and a nonmagnetic material 63” [0028] Figures 1 - 8); b. one or more application-specific modular components configured to be inserted within the enclosure (instances of “magnetic sensors 83”; Figure 6; [0027], [0030] - [0031]), wherein an application-specific modular component comprises an array of biomagnetic field sensors configured to sense an electromagnetic field associated with the individual and generate electromagnetic field data therefrom (instances of “magnetic sensors 83”; Figure 6; [0027], [0030] - [0031]); and c. one or more holes or passthroughs inserted into at least one wall of the plurality of walls (“holes 50” [0028] Figure 3 - 4), wherein a hole or passthrough is configured for passing electrical or data cabling into and out of the enclosure (“A through hole 50 for letting wirings connected to the unshown measurement equipment and the power cords and cables of the unshown supplementary equipment pass therethrough”; Figures 3 - 4; [0028]). Regarding claim 2, Shibuya teaches all limitations of claim 1. Shibuya teaches the wall comprises two or more layers (“permalloy plates 61, aluminum plates 62 and a nonmagnetic material 63” [0028] Figures 1 - 8).

Shibuya teaches the array of biomagnetic field sensors comprises at least three biomagnetic field sensors (instances of “magnetic sensors 83”; see annotated Shibuya’s Figure 6 below; [0027], [0030] - [0031]). PNG media_image1.png 418 584 media_image1.png Greyscale 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.
