OFFICE ACTION:
DETAILED ACTION
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.
Claim(s) 1-20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Buckland (U.S. Pat. NO. 10,895,197) in view of Shamoto (U.S. Pub. No. 2010/0250042).
Regarding claims 1, 9 and 17, Buckland discloses a computer-implemented (14 is the computer with 16 being the sensors and 81 being the actuators) method that, when executed by data processing hardware of a motor vehicle including a turbocharger having a turbine, causes the data processing hardware to perform operations comprising:
receiving an accelerator pedal position input indicating that a vehicle accelerator pedal has moved to an overrun position (206 and 208.  Tip-in is acceleration and tip-out is construed as the overrun position);
receiving a plurality of vehicle performance parameter inputs each corresponding to a measured vehicle performance parameter (the accelerator pedal position is a performance parameter, claim 7 of this application also states this);
calculating a vehicle dynamic score (construed as a determination of accelerating, slowing, or maintaining) based on the plurality of vehicle performance parameter inputs (206 and 208);
Note: as per applicants specification ¶46 this is simply a determination that the vehicle is in a “dynamic operating state” which will be understood as not being in steady state.
Note: the determination of a dynamic score is only “based on” the plurality of parameters which only requires using one of the plurality in order to be satisfied.
determining a target boost profile based on the calculated vehicle dynamic score (210 is determining current boost conditions in comparison to desired); and
instructing one or more outputs of the vehicle to transition to a dynamic mode to generate an increased turbine power based on the target boost profile (212).
Buckland does not disclose the plurality of vehicle performance parameter inputs including accelerator pedal position, accelerator pedal position rate of change, and accelerator pedal position accumulation.
Shamoto, which deals in vehicle control, teaches the plurality of vehicle performance parameter inputs including accelerator pedal position, accelerator pedal position rate of change, and accelerator pedal position accumulation (¶77 which discloses an integration of the pedal overtime which is rate data).
It would have been obvious to one having ordinary skill in the art at the time the invention was made to have modified Buckland with the manipulation of data of Shamoto because this allows for control of the battery (¶64).
Regarding claim 2, 10 and 18 which depends from claim 1, 9 and 17 respectively, Buckland discloses further comprising: determining that the vehicle is in a dynamic state when the calculated vehicle dynamic score exceeds a threshold vehicle dynamic score (206 and 208); and when the vehicle is in the dynamic state, instructing the one or more outputs of the vehicle to transition to the dynamic mode to generate the increased turbine power (212).
Regarding claim 3, 11 and 19 which depends from claim 1, 9 and 17 respectively, Buckland discloses wherein the one or more vehicle performance parameter inputs includes a vehicle acceleration input (pedal position option addressed with 206, 208).
Regarding claim 4, 12 and 20 which depends from claim 1, 9 and 17 respectively, Buckland discloses wherein determining that the vehicle is in a dynamic state includes determining that the vehicle is the dynamic state while the accelerator pedal is in the overrun position (208).
Regarding claim 5 and 13 which depends from claim 1 and 9 respectively, Buckland discloses wherein the one or more outputs of the vehicle include an air intake rate (wastegate option addressed), a fuel intake rate (wastegate option addressed), a wastegate actuator output (212 adjusts the wastegate), and a camshaft phaser output (wastegate option addressed).
Regarding claim 6 and 14 which depends from claim 1 and 9 respectively, Buckland discloses wherein the operation of instructing one or more outputs of the vehicle to transition to a dynamic mode occurs while the accelerator pedal is in the overrun position (212 is due to 208 which is construed as the overrun position).
Regarding claim 8 and 16 which depends from claim 7 and 15 respectively, Buckland discloses wherein the one or more vehicle performance parameter inputs includes brake pedal position, braking force, vehicle lateral force, vehicle longitudinal force, driver selected vehicle mode, engine speed, vehicle speed, and transmission gear selection (accelerator pedal position option addressed).
Regarding claim 21 which depends from claim 17, Shamoto discloses wherein the plurality vehicle of vehicle performance parameter inputs includes brake pedal position (84), braking force (¶65), vehicle lateral force (¶65 the torque request result in lateral forces), vehicle longitudinal force (¶65 the torque request result in lateral forces which can be a longitudinal force), driver selected vehicle mode (drive, reverse, park), engine speed (Ne) vehicle speed (88), and transmission gear selection (¶38).

APPLICANT REBUTTAL: REMARKSApplicant's representative would like to thank Examiner Laguarda for the courtesies extended during an interview conducted on March 27, 2025. During the interview, Applicant's representative and the Examiner discussed the interpretation of the step of calculating a vehicle dynamic score based on the plurality of vehicle parameter inputs, as provided in independent Claims 1, 9, and 17. No agreements were reached with respect to patentability. Applicant's representative and the Examiner further discussed the previous amendments to Claims 8 and 16 to recite that the vehicle performance parameter inputs include "a plurality of' instead of "one or more" of the claimed inputs. The Examiner acknowledged that the amendment was not considered in the Office Action and requires further review. Furthermore, no exhibits were shown or demonstrations conducted.Claims 1-6, 9-14, and 17-18 are now pending in the application. By this paper, Claims 1, 9, and 17 are amended, and Claims 8, 16, and 21 are cancelled without prejudice or disclaimer of the subject matter contained therein. The basis for the foregoing amendments can be found throughout the specification, claims, and drawings originally filed. No new matter has been added.The preceding amendments and the following remarks are believed to be fully responsive to the outstanding Office Action and are believed to place the application in condition for allowance.The Examiner is respectfully requested to reconsider and withdraw the rejections in view of the amendments and remarks contained herein.Rejections Under 35 U.S.C. §103 Claims 1-6, 8-14, and 16-21 stand rejected under 35 U.S.C. §103 as being unpatentable over Buckland (U.S. Patent No. 10,895,197) in view of Shamoto (U.S. Publication No.2010/0250042). These rejections are respectfully traversed.Dependent Claims 8 and 16 Initially, and as discussed in the interview on March 27, 2025, Applicant notes that the rejections of Claims 8 and 16 are based on the originally-filed claims and do not consider the amendments presented in Applicant's response filed on November 26, 2024, wherein Applicant amended each of Claims 8 and 16 to specify that "the one or more plurality of vehicle performance parameter inputs further includes brake pedal position, braking force, vehicle lateral force, vehicle longitudinal force, driver selected vehicle mode, engine speed, vehicle speed, and transmission gear selection. Accordingly, Applicant respectfully requests further examination of Claims 8 and 16 based on the amendments submitted in the response filed on November 26, 2024 In the interest of advancing prosecution, Applicant has amended each of independent Claims 1 and 9 to incorporate the elements of dependent Claims 8 and 16. Applicant respectfully submits that the amendments do not change the overall scope of the claim set from that presented in the response filed on November 26, 2024, and that the current amendments are merely intended to place the claims in condition for allowance.Independent Claims 1, 9, and 17 Applicant respectfully submits that the cited art of record, either alone or in combination, fails to teach, suggest, or disclose a method including the operations of receiving a plurality of vehicle performance parameter inputs each corresponding to a measured vehicle performance parameter, the plurality of vehicle performance parameter inputs including accelerator pedal position, accelerator pedal position rate of change, accelerator pedal position accumulation, brake pedal position, braking force, vehicle lateral force, vehicle longitudinal force, driver selected vehicle mode, engine speed, vehicle speed, and transmission gear selection, and calculating a vehicle dynamic score based on the plurality of vehicle performance parameter inputs.Buckland generally relates to a method and system for improving surge control in a boosted engine system. See Buckland at the abstract. As relied upon in the Office Action, Figure 2 of Buckland discloses steps for estimating an engine operating condition (202) and determining an initial wastegate position, CCRV position, and electric assist motor power based on the estimated engine conditions (204). See Buckland at Column 11, Lines 34-42, and Figure 2. The method then determines if there is a tip-in event (206) or a tip out event (208) based on operator torque demand and/or accelerator pedal depression. See Buckland at Column 12, Lines 19-30 and Figure 2. The method further includes determining whether there is an indication of a surge (210, 214) in connection with the tip-in event (206) or the tip-out event (206), and when there is an indication of a surge, adjusting the opening of the CCRV and the wastegate (212, 218) and adjusting output of the electric motor (218). If there is no indication of a surge, the wastegate is moved to a scheduled position, and the CCRV and electric assist motor torque are coordinated to deliver desired boost pressure (216).

The Office Action also cites generally to Paragraph [0038] of Shamoto, which discloses that a power distribution/integration mechanism (30) includes a sun gear (31), a ring gear (32), a plurality of pinion gears (34), a carrier (34), and a gear mechanism (60). As noted in the Office Action, Shamoto further discloses that an engine ECU (24) calculates engine speed (Ne) and vehicle speed (V). See Shamoto at Paragraphs [0037] and [0041].Applicant submits that the cited art of record is silent with respect to method of controlling a turbine of a motor vehicle that includes (i) receiving a plurality of vehicle performance parameter inputs including accelerator pedal position, accelerator pedal position rate of change, and accelerator pedal position accumulation, brake pedal position, braking force, vehicle lateral force, vehicle longitudinal force, driver selected vehicle mode, engine speed, vehicle speed, and transmission gear selection, and (ii) calculating a vehicle dynamic score based on the plurality of vehicle performance parameter inputs.Initially, Applicant submits that Buckland and Shamoto fail to contemplate receiving at least some of the plurality of vehicle performance parameter inputs recited in the claims. For example, the Office Action cites to Paragraph [0065] of Shamoto as disclosing the step of receiving vehicle lateral force and vehicle longitudinal force. However, as noted above and in the Office Action, Paragraph [0065] only relates to generating requests for torque. While requesting torque may cause a change in vehicle forces, Shamoto does not contemplate measuring or communicating such forces, let alone using such forces to calculate a vehicle dynamic score. Vehicle lateral force and vehicle longitudinal force are only contemplated in the Office Action as theoretical results of the requested torque.Applicant further submits that Shamoto does not contemplate receiving or using a driver selected gear mode or a transmission gear selection. The Office Action cites to Paragraph [0038] of Shamoto as disclosing a transmission gear selection. However, Paragraph [0038] appears to disclose physical gears (e.g., ring gear, sun gear, pinion gears) of a distribution mechanism instead of a gear selection.Based on the foregoing, Applicant respectfully submits that independent Claim 1, 9, and 17, as well as claims depending therefrom, are in condition for allowance. Reconsideration and withdrawal of the rejections are respectfully requested.CONCLUSIONApplicant believes this communication is fully responsive to the final Office Action mailed February 14, 2025. In the event that the Examiner does not find that the claims are in condition for allowance, Applicant requests that the Examiner contact the undersigned to discuss the merits of the case.It is believed that no additional fees are required for filing this response. However, if there are any additional charges or credits associated with this filing, please apply them to Deposit Account No. 07-0960, and reference Attorney Docket No.: P105434-PRI-NP-US01 from which the undersigned is authorized to draw.Dated: April 11, 2025
