Office Action

§103
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 . Claims 1-20 have been presented and pending in the application. 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. Claims 1, 19 & 20 are rejected under 35 U.S.C. 103 as being unpatentable over Hoshino et al. (US 2007/0192565 A1). Examiner relies on the entire teachings of the Hoshino reference for this rejection; the examiner advises the applicant to carefully consider the entire teachings of the Hoshino reference to better understand the examiner’s position and claimed interpretations applied to the claimed invention. The Hoshino reference teaches functionally equivalent recitations of the claimed invention, when the examiner applies Broadest Reasonable Interpretation, as follows: CLAIMS 1, 19 & 20 Hoshino REF. TEACHINGS 1.An embedded control circuit, comprising: Fig 1-13 with accompanying description; the examiner relies more on the teachings of fig 9 with 13 a bus interface circuit for communicating with a host processor; Figs 1, 9 & 13 with accompanying description; par 69, “external interface 140 posses and interface 143, and an external CPU 201 can be connected via the interface unit 143”; the examiner notes that the external CPU 201 is connected to a third bus 193 via 140 a processor; Figs 1, 9 & 13 with accompanying description; par 76, “internal CPU 113 controls the processing…through the first bus 191…by selecting circuits 131-136” one or more peripheral modules; Figs 1, 9 & 13 with accompanying description; par 78, “the processing circuits 121-126 can be connected to the first bus 191 or to the second bus 192…” a circuit system connected to the bus interface circuit; Figs 1, 9 & 13 with accompanying description; all connections between (140) & (191/192) a first bus connected between the one or more peripheral modules and the circuit system; and Figs 1, 9 & 13 with accompanying description; par 78, “the first bus 191 or to the second bus 192 by switching connection of each corresponding circuits 131-136” & all connections between (140) & (191/192) a second bus connected between the one or more peripheral modules and the processor; Figs 1, 9 & 13 with accompanying description; par 78, “the first bus 191 or to the second bus 192 by switching connection of each corresponding circuits 131-136” & all connections between (140) & (191/192) wherein the circuit system is configured to: Figs 1, 9 & 13 with accompanying description; all connections between (140) & (191/192) communicate with the host processor through the bus interface circuit, and access the one or more peripheral modules via the first bus according to a command from the host processor; Figs 1, 9 & 13 with accompanying description; par 70, “the external CPU 201 via the interface unit 143, and the selecting 131-136 which select each connection of the plurality of processing circuits 121-126 to the first bus or to the second bus 192” and the processor is configured to access the one or more peripheral modules via the second bus. Figs 1, 9 & 13 with accompanying description; par 70, “the internal bus 191 connected to the internal CPU 113…via interface unit 143 and selecting circuits 131-136 which select each connection of the plurality of processing circuits 121-126 to the first bus” 19.
