Office Action

§112
-10DETAILED 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 . Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after allowance or after an Office action under Ex Parte Quayle, 25 USPQ 74, 453 O.G. 213 (Comm'r Pat. 1935). Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, prosecution in this application has been reopened pursuant to 37 CFR 1.114. Applicant's submission filed on 06/01/2026 has been entered. Information Disclosure Statement The information disclosure statement (IDS) submitted on 06/01/2026 is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. 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 1-8, 10-24 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. Regarding Claims 1, 21, 22, 23, and 24, the limitations of these claims introduce a sub list of components belonging to the magnetic coupling device by stating “wherein each magnetic coupling device of the at least one magnetic coupling device comprises:” and then lists a number of components ending with “and, at least one sensor…” but then goes on to list “and a controller…”. This structural rendering introduces vagueness and contradiction into the scope of the claim leaving the boundaries of the claim unclear. It is not understood if the controller is a standalone or a distinct component of those that are part of the magnetic coupling device. Because the scope of the claim hinges on the structural boundaries of the controller and its relationship to the coupling device, this layout fails to particularly point out and distinctively claim the subject matter of the invention. Claims 2-8, 10-20 are rejected as having the same deficiencies as its parent claims. Conclusion Any inquiry concerning this communication or earlier communications from the examiner should be directed to Bernard Rojas whose telephone number is (571)272-1998.
