Office Action

§102 §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 . Priority Acknowledgment is made of applicant's claim for foreign priority under 35 U.S.C. 119(a)-(d). The certified copy has been filed in present Application filed on June 07, 2024. Information Disclosure Statement The information disclosure statements filed April 29, 2024 have been submitted for consideration. It has been placed in the application file and the information referred to therein has been considered. Applicants must continue to share 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 of Group I and Species 2 encompassing claims 1-6 in the reply filed on June 01, 2026 is acknowledged. Because applicant did not distinctly and specifically point out the supposed errors in the restriction requirement, the election has been treated as an election without traverse (MPEP § 818.01(a)). Claim Rejections - 35 USC § 112 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 1-6 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 enablement requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to enable one skilled in the art to which it pertains, and 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. Rejection of claim 1, the limitation “the first signal connector and the inter circuit board connector being configured to be capable of outputting a first signal… and wherein the first signal is input from the first circuit board to the second circuit board via the inter circuit board connector” is new matter and has enablement issue. See figure 6 wherein the inter circuit board connector 2a and 2b are connected to only 24v power. Also, see specification wherein power connectors 2a and 2b, and the main board 1 supplies power source voltage to the first circuit board 8 via the power connectors 2a and 2b. The main board 1 transmits signals to the first circuit board 8 via the signal connector 3 and receives signals from the first circuit board 8 via the connector 3. Therefore, it appears new matter based on elected species as well as having enablement issue, because no proper structure provided that showing the power connectors 2a and 2b connected to first signal. Therefore, claims contains subject matter which is not supported by proper structure and not able to understand how is able to output first signal. Rejection of claims 2-6, claims 2-6 are rejected by the same reason applied to rejection of claim 1. 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. Claim 1-6 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 claim 1, the limitation “the first signal connector and the inter circuit board connector being configured to be capable of outputting a first signal… and wherein the first signal is input from the first circuit board to the second circuit board via the inter circuit board connector” is new matter and has enablement issue. See figure 6 wherein the inter circuit board connector 2a and 2b are connected to only 24v power. Also, see specification wherein power connectors 2a and 2b, and the main board 1 supplies power source voltage to the first circuit board 8 via the power connectors 2a and 2b. The main board 1 transmits signals to the first circuit board 8 via the signal connector 3 and receives signals from the first circuit board 8 via the connector 3. Therefore, it appears new matter based on elected species as well as having enablement issue, because no proper structure provided that showing the power connectors 2a and 2b connected to first signal. Rejection of claims 2-6, claims 2-6 are rejected by the same reason applied to rejection of claim 1. Rejection of claim 5, the limitation “wherein the inter circuit board connector includes: a first inter circuit board connector that transmits the first signal, and a second inter circuit board connector that transmits the power” is indefinite or unclear. It appears that claim is misleading in term of what to consider as “a connector” or “connectors”. From the specification “A circuit board unit”, “a second signal”, and “a second signal connector” appears to be defining signal object. And “slots” “drums” “second circuit boards” “inter circuit board connectors” appears to be defining plurality. Additionally see other analogy, for example, there is clear difference between a car or a paper and cars or papers. Wherein cars includes a car; but a car can not have cars and a car can only be part of cars. Therefore, proper clarification is required. 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. Note: Rejection under USC 102 below is given to advance prosecution, however, a proper clarification or amendment is required as mentioned above under USC 112 and requires proper clarification or amendment. Claim Rejections - 35 USC § 102 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.
