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 .
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 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.
In addressing the rejection ground, each claim may not have been separately discussed to the extent the claimed features are the same as or similar to the previously-discussed features; the previous discussion is construed to apply for the other claims in the same or similar way.
In the office action, “/” should be read as and/or as generally understood. For example, “A/B” means A and B, or A or B.
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 8-17 is/are rejected under 35 U.S.C. 103 as being unpatentable over Staudinger (US 2013/0194017) in view of George US 2010/0066427 (or Lam (US 2015/0171828).
Regarding claim 8, Staudinger discloses a plurality of series-coupled phase shifter cells [e.g. fig. 2/1] each providing at least one selectable phase shift state, wherein at least one phase shifter cell [e.g. 107, 109/109,111 or any two immediately adjacent phase shifting element] includes at least two selectable signal paths [each phase shifting element has at least one selectable signal path], each selectable signal path having an active state [e.g. the bottom path] and an inactive state [e.g. the top path], wherein a first selectable signal path initially in the active state remains in the active state for a selected period of time when a next selectable signal path is set to the active state, and thereafter the first selectable signal path is set to the inactive state. Staszewski does not disclose a distinct switching delay time.
However, George discloses a distinct switching delay time [see at least para. 0015, 0020, 0024, figs. 3-5], such that the combination discloses at least one phase shifter cell has a switching delay time distinct from the switching delay time of at least one other phase shifter cell. Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the device disclosed by Staudinger in accordance with the teaching of George regarding control signals in order to reduce or eliminate switch latch-up problem [para. 0015].
Alternatively, Lam discloses a distinct switching delay time [see at least abstract, figs. 5-6], such that the combination discloses at least one phase shifter cell has a switching delay time distinct from the switching delay time of at least one other phase shifter cell. Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the device disclosed by Staudinger in accordance with the teaching of Lam regarding the timing of state transitions in order to significantly reducing glitches [see at least abstract].
Regarding claim 9, the combination discussed above discloses the plurality of series-coupled phase shifter cells of claim 8, wherein at least two phase shifter cells provide approximately the same selectable phase shift state but have distinct switching delay times.
Regarding claim 10, the combination in claim 9 discloses the plurality of series-coupled phase shifter cells of claim 8, wherein at least three phase shifter cells provide approximately the same selectable phase shift state but have distinct switching delay times.
Regarding claim 11, the combination discussed above discloses the plurality of series-coupled phase shifter cells of claim 8, further including a control signal generation circuit [e.g. 123] coupled to the selectable signal paths of at least one phase shifter cell, and configured to be coupled to a master control signal [see 157] , for generating a sequence of time-delayed control signals [e.g. 1a, 1b, 2a,… Staudinger, also see at least para. 0015, 0020, 0024, figs. 3-5 George/ see at least abstract, figs. 5-6 Lam] for the coupled selectable signal paths such that when switching from the first selectable signal path initially in the active state to the next selectable signal path initially in the inactive state, the first selectable signal path remains in the active state for a selected period of time while the next selectable signal path is set to the active state, and thereafter the first selectable signal path is set to the inactive state.
Regarding claim 12, Staudinger discloses the plurality of series-coupled phase shifter cells of claim 8, wherein at least one phase shifter cell includes at least two selectable signal paths [each phase shifting element has at least one selectable signal path] and a selectable reference path [see 129, S1b, 143; 151. S2b, the capacitor], each selectable signal path and the selectable reference path having an active state and an inactive state, wherein: (a) a first selectable signal path initially in the active state remains in the active state for a selected period of time [see at least para. 0015, 0020, 0024, figs. 3-5 George/ see at least abstract, figs. 5-6 Lam] when a next selectable signal path is to be set to the active state; (b) the selectable reference path is set to the active state during the selected period of time and before the next selectable signal path is set to the active state; (c) the next selectable signal path is set to the active state and the first selectable signal path is set to the inactive state; and (d) thereafter the selectable reference path is set to the inactive state.
Regarding claim 13, the combination discussed above discloses the plurality of series-coupled phase shifter cells of claim 12, further including a control signal generation circuit [e.g. 123] coupled to the selectable signal paths and the selectable reference path of at least one phase shifter cell, and configured to be coupled to a master control signal [see 157], for generating a sequence of time-delayed control signals [see at least para. 0015, 0020, 0024, figs. 3-5 George; or see at least abstract, figs. 4-5 Lam] for the coupled selectable signal paths and selectable reference path such that when switching from the first selectable signal path initially in the active state to the next selectable signal path initially in the inactive state, the first selectable signal path remains in the active state for a selected period of time while the selectable reference path is set to the active state, and thereafter the next selectable signal path is set to the active state and the first selectable signal path is set to the inactive state, and thereafter the selectable reference path is set to the inactive state.
Regarding claim 14, the combination discussed above discloses the plurality of series-coupled phase shifter cells of claim 12, except wherein the first selectable signal path has an opposite phase shift polarity with respect to the next selectable signal path. However, such the opposite phase shift polarity, is just am optimization for the circuitry and it is a design choice to achieve that optimum phase, since it has been held that where the general conditions of a claim are disclosed in the prior art, discovering an optimum value of a result effective variable involves only routine skill in the art. In re Boesch, 617 F.2d 272, 205 USPQ 215 (CCPA 1980).
Regarding claim 15, the combination discussed above discloses the plurality of series-coupled phase shifter cells of claim 8, wherein at least one selectable phase shift state of at least one phase shifter cell includes at least two phase shifting states [e.g. the top path for 107, the bottom path for 109; the bottom path for 107, the top path for 109; or the bottom path for 107, the bottom path for 109, Staudinger] and a through-path state [e.g. the top path for 107, the top path for 109], wherein when switching from a first phase shifting state [e.g. the top path for 107, the bottom path for 109; the bottom path for 107, the top path for 109; or the bottom path for 107, the bottom path for 109] to a next phase shifting state [e.g. the bottom path for 107, the top path for 109; the bottom path for 107, the bottom path for 109; or the top path for 107, the bottom path for 109], the at least one phase shifter cell is set to the through-path state before being set to the next phase shifting state.
Regarding claim 16, Staudinger discloses the plurality of series-coupled phase shifter cells of claim 15, further including a control signal generation circuit coupled to at least one phase shifter cell and configured to be coupled to a master control signal [see 107], the control signal generation circuit configured to generate a sequence of time-delayed control signals [see at least para. 0015, 0020, 0024, figs. 3-5 George; or see at least abstract, figs. 4-5 Lam] for the coupled at least one phase shifter cell in response to the master control signal such that when switching from the first phase shifting state to the next phase shifting state, the coupled at least one phase shifter cell is set to the through-path state before being set to the next phase shifting state.
Regarding claim 17, the combination discussed above discloses the plurality of series-coupled phase shifter cells of claim 16, wherein the control signal generation circuit is configured to delay generating the time-delayed control signals for a selectable period time.
Allowable Subject Matter
Claims 1-7 are allowed. Claims 18-20 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
Response to Arguments
Applicant's arguments filed 07/17/2026 have been fully considered but they are not persuasive.
Applicant argues:
‘Staudinger fails to disclose any teaching or suggestion that Staudinger's circuit operates such that "wherein a first selectable signal path initially in the active state remains in the active state for a selected period of time when a next selectable signal path is set to the active state, and thereafter the first selectable signal path is set to the inactive state".
Indeed, Staudinger at para. 0025 states "... wherein the first and second switch [125, 131] or integrated circuit switch [225, 231] are alternatively activated (when switch 125 is ON or CLOSED, switch 131 is OFF or OPEN)" [emphasis added]. Thus, there is no selection of a first selectable signal path that is initially in the active state and remains in the active state for a selected period of time when a next selectable signal path is set to the active state, and thereafter the first selectable signal path is set to the inactive state.’
However, a next selectable signal path does not have to be the path corresponding to switch 131/231. A next selectable signal path can be the path corresponding to switch 153/253.
For example, when bypass mode is considered as the active state, Staudinger discloses the first delay cell is in bypass mode (a first selectable signal path initially in the active state) and the second delay cell is in non-bypass/bypass mode change to the first delay cell is in bypass mode and the second delay cell is in bypass (e.g. a next selectable signal path is set to the active state), then the first delay cell transitions to non-bypass mode (e.g. inactive state); or similarly when non-bypass mode is considered as the active state, Staudinger discloses the first delay cell is in non-bypass mode and the second delay cell is in non-bypass/bypass mode (a first selectable signal path initially in the active state) change to the first delay cell is in non-bypass mode and the second delay cell is in non-bypass mode (e.g. a next selectable signal path is set to the active state), then the first delay cell transitions to bypass mode (e.g. inactive state). Accordingly, at least Staudinger discloses the features.
