Office Action

§103 §112
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 . This Office Action is responsive to the Applicant's communication filed on April 8, 2024. In view of this communication, claims 9-16 are now pending in the application. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(d): (d) REFERENCE IN DEPENDENT FORMS.—Subject to subsection (e), a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. The following is a quotation of pre-AIA 35 U.S.C. 112, fourth paragraph: Subject to the following paragraph [i.e., the fifth paragraph of pre-AIA 35 U.S.C. 112], a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. Claim 16 rejected under 35 U.S.C. 112(d) or pre-AIA 35 U.S.C. 112, 4th paragraph, as being of improper dependent form for failing to further limit the subject matter of the claim upon which it depends, or for failing to include all the limitations of the claim upon which it depends. Claim 16 recites an "ancillary unit or electromechanical brake booster of a motor vehicle" comprising an electric motor of an ancillary unit or electromechanical brake booster of a motor vehicle of claim 9, but does not recite any additional limitations of said electric motor of an ancillary unit or electromechanical brake booster of a motor vehicle. Thus, the claim does not further limit the subject matter of the claim upon which it depends. Applicant may cancel the claim(s), amend the claim(s) to place the claim(s) in proper dependent form, rewrite the claim(s) in independent form, or present a sufficient showing that the dependent claim(s) complies with the statutory requirements. 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. 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. The Examiner points out the limitation of an interference fit in claim 11 and a clearance fit in claim 12, are considered as a product-by-process limitation. “Even though product-by-process claims are limited by and defined by the process, determination of patentability is based on the product itself. The patentability of a product does not depend on its method of production. If the product in the product-by-process claim is the same as or obvious from a product of the prior art, the claim is unpatentable even though the prior product was made by a different process.” In re Thorpe, 777F, 2d 659, 698, 227 USPQ 964, 966 (Fed. Cir. 1985); see also MPEP 2113 Claim(s) 9-16 is/are rejected under 35 U.S.C. 103 as being unpatentable over RITTER (US 20140054996 A1) in view of HOSHINA (JP 2020118179 A). In regards to claim 9, RITTER teaches: An electric motor (Fig 1; 10) of an ancillary unit or electromechanical brake booster of a motor vehicle[0002], the electric motor (Fig 1; 10) comprising: a rotor shaft (Fig 1; 26)disposed along a rotor axis(Fig 1; A), said rotor shaft (Fig 1; 26)including: a cylindrical main portion (Fig 1; 26) having a round cross section perpendicular to said rotor axis(Fig 1; A)(Fig 1 shows a cylindrical shaft) a gear wheel (Fig 1; 42) PNG media_image1.png 384 728 media_image1.png Greyscale RITTER does not teach: an assembly portion adjoining said main and having a barrel- shaped cross section perpendicular to said rotor axis, two mutually parallel main edges, and two convex edges; and a gear wheel disposed on said assembly portion, said gear wheel having a central assembly opening with a barrel-shaped cross section perpendicular to said rotor axis. HOSHINA teaches: a cylindrical main portion(Fig 5; 55) (Fig 1; 26) having a round cross section perpendicular to said rotor axis(Fig 1; A)(Fig 1 shows a cylindrical shaft)(Fig 5 shows a circular cross section of main portion 55), and an assembly portion (Fig 5; 51)adjoining said main portion (Fig 5; 55) (Fig 7 shows parts adjoined)and having a barrel- shaped cross section perpendicular to said rotor axis(Fig 5 shows a barrel cross section of assembly portion 51), two mutually parallel main edges(Fig 5; 53), and two convex edges(Fig 5; 52); and a gear wheel (Fig 1; 42) (Fig 5; 60)disposed on said assembly portion(Fig 5; 51), said gear wheel(Fig 1; 42) (Fig 5; 60) having a central assembly opening (Fig 5; 62)with a barrel-shaped cross section perpendicular to said rotor axis(Fig 5 shows a barrel cross section of assembly opening 62). PNG media_image2.png 755 405 media_image2.png Greyscale PNG media_image3.png 767 438 media_image3.png Greyscale Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the rotor shaft of RITTER by adding the assembly portion taught by HOSHINA and using the gear wheel taught by HOSHINA in order to preventing rattling of gear parts mounted on a rotary shaft and concentrically disposing the rotary shaft and the gear parts [0005 HOSHINA]. Additionally, the Applicant should note that it would have been obvious to one having ordinary skill in the art at the time the invention was made to use a “Double-D shaft” or “flat shaft” since it was known in the art that a “Double-D shaft” or “flat shaft” is a common structure used in machine design to fix rotation. In regards to claim 10, RITTER, in view of HOSHINA, teaches the electric motor according to claim 9: wherein said gear wheel (Fig 1; 42)is helically toothed(shown in Fig 1) relative to said rotor axis(Fig 1; A). In regards to claim 11, RITTER, in view of HOSHINA, teaches the electric motor according to claim 9. RITTER does not teach: wherein said assembly opening has main edges, and an interference fit is established between said main edges of said assembly portion and said main edges of said assembly opening. HOSHINA teaches: wherein said assembly opening(Fig 5; 62) has main edges(Fig 5; 65’), and an interference fit(interference fit is a product by process) is established between said main edges(Fig 5; 53) of said assembly portion and said main edges(Fig 5; 65’) of said assembly opening. In regards to claim 12, RITTER, in view of HOSHINA, teaches the electric motor according to claim 9. RITTER does not teach: wherein said assembly opening has convex edges, and a clearance fit is established between said convex edges of said assembly portion and said convex edges of said assembly opening. HOSHINA teaches: wherein said assembly opening (Fig 5; 62)has convex edges(Fig 5; 65), and a clearance fit (clearance fit is a product by process) is established between said convex edges (Fig 5; 52)of said assembly portion and said convex edges (Fig 5; 65)of said assembly opening. In regards to claim 13, RITTER, in view of HOSHINA, teaches the electric motor according to claim 9. RITTER does not teach: wherein said assembly opening has main edges, convex edges and corners each formed between a respective one of said main edges and a respective adjacent one of said convex edges, said gear wheel has teeth, and each tooth is disposed adjacent to a respective one of said corners in a radial direction. HOSHINA teaches: wherein said assembly opening (Fig 5; 62)has main edges(Fig 5; 65’), convex edges (Fig 5; 65)and corners (Fig 5; 63/64)each formed between a respective one of said main edges (Fig 5; 65’)and a respective adjacent one of said convex edges(Fig 5; 65), said gear wheel(Fig 5; 60) has teeth(Fig 5; 61), and each tooth(Fig 5; 61) is disposed adjacent to a respective one of said corners(Fig 5; 63/64) in a radial direction. In regards to claim 14, RITTER, in view of HOSHINA, teaches the electric motor according to claim 9. RITTER does not teach: wherein said rotor shaft has a circumferentially encircling step formed between said assembly portion and said main portion. HOSHINA teaches: wherein said rotor shaft (Fig 5; 50)has a circumferentially encircling step(step shown in Fig 7) formed between said assembly portion (Fig 7; 51)and said main portion(Fig 7; 55). In regards to claim 15, RITTER, in view of HOSHINA, teaches the electric motor according to claim 9. RITTER does not teach: wherein said assembly portion has a beveled end facing away from said main portion. HOSHINA teaches: wherein said assembly portion(Fig 7; 51) has a beveled end(step shown in Fig 7) facing away from said main portion(Fig 7; 55). In regards to claim 16, RITTER, in view of HOSHINA, teaches the electric motor according to claim 9: an ancillary unit or electromechanical brake booster of a motor vehicle[0002], the ancillary unit or electromechanical brake booster [0002]comprising an electric motor(Fig 1; 10).
