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 1-3, 5-7 and 21 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.
Claims 1, 11 and 21 recite “the multiplexing circuit is free from coupling a passive inductor to the output terminal of the multiplexing circuit.” It is unclear how the multiplexing circuit is free from coupling a passive inductor to the output terminal of the multiplexing circuit. The applicant drawing figure 2 shows that the multiplexing circuit is coupling [through R1] a passive inductor [L1] to the output terminal of the multiplexing circuit [OUT].
Claims 2-3 and 5-7 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being depended on claim 1.
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 1-2 and 7 are rejected under 35 U.S.C. 103 as being unpatentable over Forbes (US 6597203) in view of in view of Raman et al. (US 6424170 and Raman hereinafter).
Regarding claim 1, Forbes discloses a multiplexing circuit [figs. 6, 7 and 15], comprising: a first type transistor [604, fig. 6], wherein a gate terminal [gate 604, fig. 6] of the first type transistor is configured to receive a control signal [signal A] and free from receiving a clock signal [CLK]; a second type transistor [610, fig. 6], coupled to the first type transistor, wherein a gate terminal [gate 610] of the second type transistor is configured to receive the clock signal [CLK], and an output terminal [612], coupled between the first type transistor and the second type transistor; wherein the multiplexing circuit is free from coupling a passive inductor to the output terminal of the multiplexing circuit [Examiner noted that a passive inductor not required as claim limitation because multiplexing circuit is free from coupling a passive inductor to the output terminal of the multiplexing circuit and a passive inductor is not recited anywhere else in the claim and is not structurally connected to any other claimed element.]. Forbes does not disclose an impedance circuit arranged to provide an impedance between the first type transistor and the second type transistor.
However, Raman discloses [figs. 1 and 3] an impedance circuit [LRB, fig. 3] arranged to provide an impedance between a first type transistor [30, fig. 3] and a second type transistor [20, fig. 1]. It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention was made to modify the invention of Forbes by incorporating the impedance circuit as taught in Raman in order to provides matching termination that suppresses overshoots and residual noises, and also improves signal quality, timing, and device reliability [cl. 3~cl. 4].
Regarding claim 2, Forbes in view of Raman discloses [fig. 6] wherein the impedance circuit is connected to the output terminal [fig. 3].
Regarding claim 7, Forbes in view of Raman discloses [fig. 6] wherein the impedance circuit is free from connecting to the gate terminal of the second type transistor.
Claims 5-6 are rejected under 35 U.S.C. 103 as being unpatentable over Forbes in view of in view of Raman et al.
Regarding claim 5, Forbes in view of Raman discloses all the features with respect to claim 2 as indicated above. Forbes in view of Raman further discloses [fig. 6] wherein the first type transistor is a N-type Metal Oxide Semiconductor [604], a drain terminal of the NMOS is coupled to a first reference voltage [ground], and a source terminal of the NMOS is coupled to the output terminal. Forbes in view of Raman does not explicitly disclose the first type transistor is a P-type Metal Oxide Semiconductor. Although Forbes in view of Raman discloses uses N-type MOSFETs instead of P-type Metal Oxide Semiconductor for the first transistor, the transistor is just different type of transistor and thus it would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to substitute one type of transistor for the other in the absence of unexpected results in order to have an optimum working condition for the circuit since this practice is well known in the art.
Regarding claim 6, Forbes in view of Raman discloses all the features with respect to claim 2 as indicated above. Forbes in view of Raman further discloses [fig. 6] wherein the second type transistor is P-type Metal Oxide Semiconductor (PMOS) [610], a drain terminal of the NMOS is coupled to the output terminal, and a source terminal of the NMOS is coupled to a second reference voltage [VDD]. Forbes in view of Raman does not explicitly disclose the second type transistor is N-type Metal Oxide Semiconductor. Although Forbes in view of Raman discloses uses P-type MOSFETs instead of N-type Metal Oxide Semiconductor for the second transistor, the transistor is just different type of transistor and thus it would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to substitute one type of transistor for the other in the absence of unexpected results in order to have an optimum working condition for the circuit since this practice is well known in the art.
Response to Arguments
Applicant's arguments filed 05/11/2026 have been fully considered but they are not persuasive.
Regarding claim 1, the amended feature “and an output terminal, coupled between the first type transistor and the second type transistor”. Forbes discloses an output terminal [612, fig. 6], coupled between the first type transistor [604, fig. 6] and the second type transistor [610, fig. 6]. And for the amended limitation “wherein the multiplexing circuit is free from coupling a passive inductor to the output terminal of the multiplexing circuit”. Examiner noted that a passive inductor is not required as claim limitation because the claim recites multiplexing circuit is free from coupling a passive inductor to the output terminal of the multiplexing circuit and a passive inductor is not recited anywhere else in the claim and is not structurally connected to any other claimed element. Accordingly, since the cited reference does not include passive inductor and therefore free from any coupling to the output of multiplexing circuit. Therefore, Forbes/Raman still read on the claims and the rejection stands.
Allowable Subject Matter
Claims 8-10 and 12-20 are allowed.
Claims 3, 11 and 21 would be allowable if rewritten to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action and to include all of the limitations of the base claim and any intervening claims.
