DETAILED ACTION
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.
Claims 1-5 and 10-12 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Bach et al. (DE 102010030277 B4).
Re claim 1, Bach et al. teach an actuator assembly of an electromechanical vehicle brake, comprising a brake piston (1) which is linearly displaceable in an axial direction and which serves to apply a brake pad to a brake rotor, a brake calliper unit in which there is formed a holder (2) having an inner circumferential surface which forms a running surface for the brake piston, and a rotation prevention arrangement, wherein the rotation prevention arrangement comprises a ring (9) pushed onto a contact surface on the brake piston and connected in a rotationally fixed manner to the brake piston at an inner circumferential surface, said ring having at least one radially outwardly protruding securing projection (11), and a groove (12), associated with the securing projection, the groove running in an axial direction in the inner circumferential surface of the holder and in which the securing projection is held in such a manner that the brake piston is guided in a rotationally secure manner in the brake calliper unit. (Fig. 2-4)
Re claim 2, Bach et al. teach wherein the groove (12) is closed at an end directed towards the contact surface and forms an axial stop for the securing projection. (See element 12 – Fig. 1)
Re claims 3 and 10, Bach et al. teach wherein the ring (9) is capable of being pressed onto the brake piston (1). (Fig. 2-3)
Re claims 4 and 11, Bach et al. teach wherein the contact surface on the brake piston (1) is a circumferential surface at an axial end of the brake piston that is directed into an interior of the holder. (Fig. 2-3)
Re claims 5 and 12, Bach et al. teach wherein the contact surface terminates at an axial shoulder which forms an axial end stop for the ring (9) in a mounted state. See shoulder at element 11 in Fig. 2.
Allowable Subject Matter
Claims 6-9 and 13 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.
Hess teaches an actuator assembly comprising a brake piston which is linearly displaceable in an axial direction and which serves to apply a brake pad to a brake rotor, a brake calliper unit in which there is formed a holder having an inner circumferential surface which forms a running surface for the brake piston, and a rotation prevention arrangement, wherein the rotation prevention arrangement comprises a ring pushed onto a contact surface on the brake piston and connected in a rotationally fixed manner to the brake piston at an inner circumferential surface, said ring having at least one radially outwardly protruding securing projection, and a groove, associated with the securing projection, the groove running in an axial direction and in which the securing projection is held in such a manner that the brake piston is guided in a rotationally secure manner in the brake calliper unit.
Li teaches an actuator assembly comprising a brake piston which is linearly displaceable in an axial direction and which serves to apply a brake pad to a brake rotor, and a rotation prevention arrangement, wherein the rotation prevention arrangement comprises a ring pushed onto a contact surface on the brake piston and connected in a rotationally fixed manner to the brake piston said ring having at least one radially outwardly protruding securing projection, and a groove, associated with the securing projection in which the securing projection is held in such a manner that the brake piston is guided in a rotationally secure manner in the brake calliper unit.
Al-Mahshi ‘265 and ‘311 teach an actuator assembly of an electromechanical vehicle brake, comprising a brake piston which is linearly displaceable in an axial direction and which serves to apply a brake pad to a brake rotor, a brake calliper unit in which there is formed a holder having an inner circumferential surface which forms a running surface for the brake piston, and a rotation prevention arrangement, wherein the brake piston is guided in a rotationally secure manner in the brake calliper unit.
