Office Action

§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 . Information Disclosure Statement The information disclosure statement filed 9/18/25 fails to comply with the provisions of 37 CFR 1.98(a)(4) because it lacks the appropriate size fee assertion. It has been placed in the application file, but the information referred to therein has not been considered as to the merits. 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 1-2, 6-10, 12-15, and 20 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. Claim 1 recites, “the images having a submicron spatial resolution and frequency bandwidth extending from substantially 0 Hz (DC) to at least 1 GHz.” It is unclear what is meant by a “frequency bandwidth” in the context of images. In particular, this limitation could refer to the frequency of image refresh (i.e., 1 GHz = 10^9 images per second) or it could refer to the electrical signals generated by the Josephson Junction. This lack of clarity makes the claims indefinite. The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claims 1-2, 6-10, 12-15, and 20 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. Claim 1 is amended to recite a display for displaying “concurrently and in real time without scanning…a sequence of spatial images collectively depicting temporal changes in magnetic flux.” The applicant has provided no explanation of where these limitations may find support in the original disclosure, and a review of the disclosure has found no such support. As such, the limitations at issue are new matter, and the claim is rejected for failing the written description requirement. Claim 10 is rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. Claim 10 is amended to recite an indicator array “is a magnified two-dimensional scaling of the sensor array, each indicator region being a magnified representation of a corresponding sensor pixel, such that submicron flux variations are presented in a format directly perceivable by a human observer without post- processing.” The applicant has provided no explanation of where these limitations may find support in the original disclosure, and a review of the disclosure has found no such support. As such, the limitation at issue is new matter, and the claims are rejected for failing the written description requirement. Response to Arguments Applicant’s arguments with respect to claim(s) 1-20 have been considered. The applicant’s amendments to overcome the indefiniteness, obviousness, and anticipation rejections of the past action have rendered the claims noncompliant with respect to 35 USC 112(a). Nonetheless, these amendments have overcome the previous office action’s rejections in those regards. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. US 10,539,633 is relevant to the instant invention. Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). 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.
