Office Action

§102
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 . Claim Rejections - 35 USC § 102 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 the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claim(s) 1-7 and 15 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by JP 57-21068 B2. Re-claim 1, JP ‘068 discloses a brake device (see figures 5-9) for a vehicle, the brake device comprising: a housing part 19 (not shown, see page 4 paragraphs 6-8); a gear part 47 (or pulley 49) is rotatably disposed at the housing part and rotates in response to a rotational force received from a motor 14; a motion conversion part 44/45 is housed within the housing part, coupled to the gear part, and converts a rotational motion of the gear part into a rectilinear motion (see comparison between figures 8 and 9); a piston part 7 is coupled to the motion conversion part and is rectilinearly movable; a master cylinder part 2 is coupled to a first side of the housing part, the piston part 7 is inserted into the master cylinder part; and a pedal simulator part 18 is slidably disposed at a second side of the housing part and coupled to the motion conversion part. Re-claim 2, a first bearing part 43 disposed within the housing part, the gear part 47 is rotatably coupled to the first bearing part. Re-claim 3, the motion conversion part comprises: a screw bolt part 44 slidably coupled to the gear part (as shown the gear part 47 is slide over or pressed onto bolt part 44, this is consistent with the instant invention, see paragraphs 42-44) and rotates together with the gear part 47; a nut part 45 is coupled to the screw bolt part and moves along the screw bolt part. Re-claim 4, the piston part 7 is coupled to the nut part and configured to move together with the nut part. Re-claim 5, a first elastic part 29 is disposed within the housing part and elastically supports the nut part 45 (which includes 51/52, as 51/52 is fixedly attached to the nut, see page 4 paragraph 8: “ link member 50 includes a connection portion 51 that is connected to the outer periphery of the linear motion member 45 so as not to be relatively rotatable, and a disk-shaped propulsion portion 52”). Re-claim 6, the nut part 45 comprises: a nut body part 45 spirally coupled to the screw bolt part 44; and an anti-rotation part 53 (as part of 52) is disposed on the nut body part and restricts a rotation of the nut body part. Re-claim 7, the anti-rotation part comprises: a first seating portion 52 protruding from the nut body part (see figure 6), the first elastic part 29 is disposed on the first seating portion; and a protruding portion 53 protruding from the first seating portion and adjoining an inner surface of the housing part (see page 4 paragraph 8: “rotation preventing portion 53 can be moved in the axial direction of the piston 7 by a support portion (not shown) of the housing 19 and is supported so as not to move in the circumferential direction of the piston 7”). Re-claim 15, JP ‘068 discloses a brake device for a vehicle, the brake device comprising: a housing part 19; a gear part 47 is rotatably housed within the housing part and rotates in response to a rotational force received from a motor 14; a motion conversion part 44/45 is disposed within the housing part, coupled to the gear part, and converts a rotational motion of the gear part into a rectilinear motion; a piston part 7 is coupled to the motion conversion part and is rectilinearly movable; a master cylinder part 2 is coupled to a first side of the housing part, the piston part is inserted into the master cylinder part to generate a hydraulic pressure; a pedal simulator part 18 disposed at a second side of the housing part and coupled to the motion conversion part, wherein the pedal simulator part is configured (1) not to move by a reaction force of the hydraulic pressure when the motor is operated, and (2) to slidably move when the motor is not operated (see figure 9). Operation of the pedal will compress the pedal simulator. The pedal simulator is not fixedly attached to the nut 45 (and 52) and thus will not compress when only the motor is operated to move the nut 45. Allowable Subject Matter Claims 8-14 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. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Hu teaches a nut that is moved along a screw for actuating a piston. Wieberle, Vollert and Svensson each teach a mechanically actuated brake booster.
