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 .
Status of Claims
Claims 1-7, 11-17, and 21-26 are currently pending in the application. Claims 21-26 are withdrawn for being drawn to a nonelected invention.
Election/Restrictions
Applicant’s election of Group I. in the reply filed on 12/31/2025 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)).
Claims 21-26 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected invention, there being no allowable generic or linking claim.
Priority
Acknowledgment is made of applicant’s claim for foreign priority under 35 U.S.C. 119 (a)-(d). Receipt is acknowledged of certified copies of papers filed on 07/26/2024 as required by 37 CFR 1.55.
Information Disclosure Statement
The information disclosure statement (IDS) submitted on 07/26/2024 is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner.
Drawings
The drawings are objected to because:
In Fig. 4 at 261 “SECOND GATE DRIVER” should read --SECOND INVERTER--.
In Fig. 5 at 261 “SECOND GATE DRIVER” should read --SECOND INVERTER--.
Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance.
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 2-3, 5-7, 12-13, and 15-17 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 pre-AIA the applicant regards as the invention.
Claim 2 recites the limitation “when the periodic signal is not received from the first processor, the second processor controls the parking brake based on the output signal of the parking switch” in lines 1-3. The claim is indefinite because the claim also recites controlling the parking brake based on the pedal sensor when the periodic signal is not received (claim 1 lines 12-13). Therefore, it is unclear whether the parking brake is controlled based on the pedal sensor or the parking switch when the periodic signal is not received. For examination purposes the claim has been considered as best understood by the Examiner.
Claim 3 recites the limitation “when…the output signal of the pedal sensor is valid” in lines 1-2. There is insufficient antecedent basis for the limitation in the claim because the claim does not recite determining the validity of the pedal sensor. For examination purposes the claim has been considered as reciting --wherein the second processor determines whether the output signal of the pedal sensor is valid-- after the preamble of claim 3.
Claim 5 recites the limitation “when…the output signal of the wheel speed sensor is valid” in lines 1-3. There is insufficient antecedent basis for the limitation in the claim because the claim does not recite determining the validity of the pedal sensor. For examination purposes the claim has been considered as reciting --wherein the second processor determines whether the output signal of the wheel speed sensor is valid-- after the preamble of claim 5.
Claim 6 recites the limitation “when the periodic signal is received from the first processor while the parking brake is controlled based on the output signal of the pedal sensor” in lines 1-3. There is insufficient antecedent basis for the limitation in the claim because the claim recites controlling the parking brake based on the pedal sensor when the periodic signal is not received. For examination purposes the limitation has been considered as best understood by the Examiner.
Claim 12 recites the limitation “when the periodic signal is not received from the first processor, controlling, by the second processor, the parking brake based on the output signal of the parking switch” in lines 1-3. The claim is indefinite because the claim also recites controlling the parking brake based on the pedal sensor when the periodic signal is not received. Therefore, it is unclear whether the parking brake is controlled based on the pedal sensor or the parking switch. For examination purposes the claim has been considered as best understood by the Examiner.
Claim 13 recites the limitation “when…the output signal of the pedal sensor is valid” in lines 3-4. There is insufficient antecedent basis for the limitation in the claim because the claim does not recite determining the validity of the pedal sensor signal. For examination purposes the claim has been considered as reciting --further comprising identifying whether the output signal of the pedal sensor is valid-- after the preamble of claim 13.
Claim 15 recites the limitation “when…the output signal of the wheel speed sensor is valid” in lines 3-4. There is insufficient antecedent basis for the limitation in the claim. For examination purposes the claim has been considered as reciting --further comprising identifying whether the output signal of the wheel speed sensor is valid” after the preamble of claim 15.
Claim 16 recites the limitation “when the periodic signal is received from the first processor while the parking brake is controlled based on the output signal of the pedal sensor” in lines 1-3. There is insufficient antecedent basis for the limitation in the claim because the claim recites controlling the parking brake based on the pedal sensor when the periodic signal is not received. For examination purposes the limitation has been considered as best understood by the Examiner.
Claims 7 and 17 are rejected for depending upon indefinite base claims.
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 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.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claims 1-5 and 11-15 are rejected under 35 U.S.C. 103 as being unpatentable over TARANDEK (WO 2020/204509, English language equivalent in US 12,472,918) in view of ALFORD (US 2021/0179051, provided by Applicant on 07/26/2024 IDS) and ZHANG (US 2024/0359669).
Regarding claim 1, TARANDEK discloses a brake device comprising:
a hydraulic pressure supply unit (15, Fig. 3) fluidly connected to wheel cylinders (FA,RA) of a vehicle (col. 5 lines 52-53, Fig. 3);
a parking brake (1, col. 4 lines 7-9) provided on at least one of the wheel cylinders (Fig. 3);
a first processor (2) electrically connected to the hydraulic pressure supply unit and the parking brake (col. 4 lines 12-15); and
a second processor (3) electrically connected to the parking brake (col. 4 lines 15-19, Fig. 3) and electrically connected to the first processor through a signal line (implied by “communication interface” connecting microprocessors in Fig. 2, Fig. 3),
wherein the first processor (implied) controls the hydraulic pressure supply unit based on an output signal of a pedal sensor (12) of the vehicle (col. 5 lines 65-67), and controls the parking brake based on an output signal of a parking switch (10) of the vehicle (col. 6 lines 3-7).
TARANDEK is not relied upon to teach the second processor controls the parking brake based on the output signal of the pedal sensor when the first processor malfunctions.
ALFORD teaches when a first processor (180, Fig. 2) malfunctions (0098 lines 1-5; failure of functional unit 110 may include failure of first processor, 0089 lines 12-13), a second processor (180’, Fig. 2) controls a parking brake (EPB1,EPB2, Fig. 2) based on the output signal of a pedal sensor (130, 0098 lines 5-8) in order to cause, increase or reduce a vehicle deceleration or in order to increase or reduce a wheel velocity in a wheel-specific manner (0089 lines 15-18).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to configure the second processor of TARANDEK to control the parking brake based on the output signal of the pedal sensor when the first processor malfunctions as taught by ALFORD in order to cause, increase or reduce a vehicle deceleration or in order to increase or reduce a wheel velocity in a wheel-specific manner and potentially prevent an accident.
TARANDEK and ALFORD are silent regarding how the second processor determines malfunction of the first processor.
ZHANG teaches a first processor (121) provides a periodic signal (0141 lines 5-7) to a second processor (123) through a signal line (0141 lines 1-5), and
when the periodic signal is not received from the first processor (0141 lines 12-13), the second processor determines malfunction of the first processor (0141 lines 13-15) so that the second processor may switch to an effective state to perform braking based on a stepping indication of a driver (0141 lines 16-18).
Absent guidance from TARANDEK and ALFORD, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to configure the brake device of TARANDEK such that the second processor may determine malfunction of the first processor as taught by ZHANG so that the second processor may switch to an effective state to perform braking based on a stepping indication of a driver and potentially prevent an accident.
