Office Action

§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. Claim Objections Claims 1, and 13 is objected to because of the following informalities: Regarding claims 1 and 13, in line 1, the recitation “An inerting device for a battery comprising a first terminal and a second terminal, the first terminal and the second terminal presenting opposite polarity, the inerting device comprising a connection circuit”, is unclear. It is unclear whether a first terminal and a second terminal are a part of the battery or inerting device. By reviewing the specification, the examiner figured out that the terminals are the battery terminals. For clarity purposes, the claim can be written as : “An inerting device for a battery, where the battery comprising a first terminal and a second terminal, the first terminal and the second terminal presenting opposite polarity, the inerting device comprising: a connection circuit” . 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 appl icant regards as his invention. Claim 4 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. Regarding claim 4, the claim recites “ wherein the connection circuit is configured to supply the same charging circuit ” , is not clear. It is unclear that what charging circuit the connection circuit is configured to supply and how the recited limitation should be interpreted. The scope of this limitation cannot be determined with reasonable certainty, the claim is indefinite. Appropriated correction is required. 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. Claim (s) 1-15 is/are rejected under 35 U.S.C. 103 as being unpatentable over IRVIMÄKI, M., "COMPONENT TESTING FOR SPACECRAFT POWER SUBSYSTEM PASSIVATION FUNCTION" TAMPEREEN TEKNILLINEN YLIOPISTO TAMPERE UNIVERSITY OF TECHNOLOGY, (2017 ), and Newton ( US 9 , 263 , 903 ).
