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 . Information Disclosure Statement The information disclosure statements filed April 24,2025 have been submitted for consideration by the Office. It has been placed in the application file and the information referred to therein has been considered. Applicants must continue to submit prior art references throughout the patent application process. A supplemental IDS must be submitted if prior art is discovered through a foreign patent application or an International Patent Search, or a related application before a prosecution closes. Election/Restriction Applicant’s election with traverse of Group I, encompassing claims 1-8 and 15-20 in the reply filed on April 21, 2026 is acknowledged. However, no reason was given for the traversal; therefore, the requirement is still deemed proper and is made FINAL. 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 and 15-20 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. Rejection of claims 1, and 15, limitations “ busbars formed on opposite surfaces of a substrate; and a power module formed on the substrate sandwiched between the busbars and electrically connected to the busbars, the power module comprising power switches that control flow of an electrical current between the busbars’ is unclear or indefinite. It is not clear how busbars formed on opposite surfaces of a substrate such that busbars has a first portion of each of the busbars on a first surface of the opposite surfaces of a substrate, and a second portion of each of the busbars on a first surface of the opposite surfaces of a substrate; or busbars has a first set of busbars on a first surface of the opposite surfaces of a substrate, and a a second set of busbars on a second surface of the opposite surfaces of a substrate; and so on. Proper clarification is required. Similarly, same reason applied to a power module formed on the substrate sandwiched between the busbars. Furthermore, it requires that through hole via conductors in the substrate are connected to power switches as necessary structure to a power module electrically connected to the busbars. Therefore, proper modification is required. Rejection of claim 2-8, and 16-20, claims 2-8, and 16-20 are rejected by the same reason applied to rejection of claims 1, or 15. 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-AlA) 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. Claim Rejections - 35 USC § 103 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. Claims 1-3 and 8 are rejected under 35 U.S.C. 103 as being unpatentable over Kratzer et al. (US20210360788, herein referred to as Kratzer) or Forssell et al. (US20230187713, herein referred to as Forssell).
