§103
DETAILED ACTION Notice of Pre-AIA or AIA Status 1. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . 2. Claims 1-7 and 9-20 are pending. 3. 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 final rejection. 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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 06/24/2026 has been entered. Response to Arguments 4. Applicant’s arguments with respect to the amended independent claims have been considered but are moot in view of the new ground(s) of rejection in which the Examiner has cited newly presented prior art, Nakamura (US Pub. No. 2011/0019231 A1 hereinafter “Nakamura”), as necessitated by the amended independent claims disclosing wherein the process of converting the input information into the transmission packet comprises: by the main control device, interpreting parameters of the input information and mapping the parameters of the input information into a data format conforming to the transmission protocol to generate the transmission packet. Claim Rejections - 35 USC § 103 5. 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. 6. Claims 1-7, 10-18 and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Chang et al. (US Pub.

[0064] discloses when the data to be transmitted is input from the CPU 21, the serial interfaces 2A, 2B convert the input data and produce packets conforming to the protocol defined by the relevant specification, and transmit the resulting packets through the communication lines 3A, 3B. See Fig. 6 & par. [0103-0108].). It would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to include Nakamura’s teachings with Chang, Jiangsu and Suzhou’s techniques for the benefit of connecting a host computer and recording device using an existing communication interface so that data can be transmitted at high speed between the host computer and recording device (Nakamura – Par. [0006]). Referring to claim 2, Chang, Jiangsu, Suzhou and Nakamura disclose method for switching the input device according to claim 1, wherein connecting the main control device to the input device and detecting the input information of the input device comprises: retrieving, by the main control device, an input event of the input device by using a system event hook program, wherein the input event comprises the input information (Chang – Par.
