Office Action

§102
Final 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 . Response to Arguments Applicant's arguments filed 07/21/2026 have been fully considered but they are not persuasive. The rejections under 35 USC 102(a)(2) of claims 1-26 and 29 as anticipated by Marchand as part of US 20140360062 A1, hereinafter referred to as Marchand, are sustained. With respect to the rejections under 35 USC 112(a) and 112(b) of claims 13 and 26, in light of the amendments made to remove the non-enabling and indefinite language, said rejections are moot and have been withdrawn. In the interest of compact prosecution, examiner wishes to respond to specific arguments made by applicant. Applicant directs arguments to the requirements shared between claims 1 and 14, specifically that the tertiary fit face of the mounting nose is required to 1) extend laterally at an angle between each side wall and one of either the top surface or bottom surface, and 2) extend rearwardly, substantially in a plane, from the front bearing face to a rear end of the mounting nose. Applicant argues that Marchand does not disclose, teach, or suggest an excavator mounting nose that has both of these limitations. Applicant argues that the tertiary fit faces described in the previous office action do not extend rearwardly, substantially in a plane, from the front bearing surface to a rear end of the mounting nose as required. Applicant asserts that the tertiary fit face is comprised of three faces that lie in different planes along the extension from the front bearing face to the rear end of the mounting nose, and as such is fundamentally incompatible with the claimed invention. Applicant further asserts that the fit faces do not extend between a top surface and a side wall, rather extending between a further surface that is located between the fit face and the top surface, and on the other side, a further surface between the fit face and the side wall. Examiner does not find these arguments persuasive. The claimed language does not require a single, substantially planar face that extends between the front bearing face and the rear end of the socket cavity; instead, the claim language specifically refers to “tertiary fit faces extending laterally at an angle between each opposed side wall and one of the top or bottom wall, wherein each tertiary fit face also extends rearwardly substantially in a plane”. In light of the broad language defining the tertiary fit faces, a broad, reasonable interpretation of the tertiary fit faces comprising several, independently substantially planar faces that extend contiguously between a front bearing surface and a rear end of the part, such as is taught by Marchand, is possible. Further, there is no requirement that the top surface or bottom surface and respective side surface between which the tertiary fit faces laterally extend cannot be joined by an additional face; in the case of Marchand, the beveled edge described by Applicant. 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)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claims 1-26 and 29 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Marchand as part of US 20140360062 A1, hereinafter referred to as Marchand. Regarding Claim 1: Marchand teaches of an excavator wear member, the excavator wear member comprising: a socket cavity opening at a rear end of the wear member, the socket cavity at least partially defined by a top wall, a bottom wall, opposed side walls and a front bearing face (Fig. 1-3,; Paragraph 39, tooth 10 comprises an internal recess designed to have a complementary profile of support 20 and nose 30, which comprises a top surface comprising top face 41, 61, and 81, bottom surface comprising bottom face 45,65, and 85, a left-handed face comprising face 47,67, and 87, a right handed face comprising face 43, 63, and 83, and flat face 34); and tertiary fit faces extending laterally at an angle between each opposed side wall and one of the top wall or the bottom wall (Fig. 3-4, tooth 10 comprises complementary surfaces to nose 30, namely the symmetrical right hand top face 42, 62, and 82, right hand bottom face 44, 64, and 84, left hand bottom face 46, 66, and 88, and left hand top face 48, 68, and 88, which extend laterally at an angle between each respective left hand and right hand faces and the top and bottom faces); wherein each tertiary fit face also extends rearwardly substantially in a plane within the socket cavity from the front bearing face to a rear end of the socket cavity (Fig. 3-4, each complementary tertiary face matching the profile of nose 30 extends rearwardly in a plane along the interior of the recess towards the opening of the recess).
