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
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 1-15 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Alzingre et al (US 20220021289 A1).
With respect to claim 1, Alzingre discloses a three-phase electric motor, comprising: a stator part excited by three electric windings (fig. 11 stator 16); and a rotor comprising a plurality of magnetized poles (fig. 11, rotor 18), the stator part having radially extending teeth (fig. 11, motor coil 20) the radially extending teeth including:-three consecutive wound teeth (fig. 11, motor 20 are wound), each carrying a winding (paragraph 76 “three poles (17) carry motor coils (20) in order to generate the rotating field driving the magnetic rotor (18),”), in a first angular set (see figure 11, poles 17 are in a set); and one to three non-wound complementary teeth, in a second angular sector complementary to the first angular sector (see fig. 11 marked below).

With respect to claim 2, Alzingre discloses an angular width and a length non-wound teeth are configured so as to shape a current-free torque curve of the three-phase electric motor, to favor the regularity and smoothness, or a more or less steep indexing of the current-free torque (see at least figure 11, and paragraph 77 “A device according to the present disclosure makes it possible to introduce a controllable force into an electric motor or actuator by making it possible to add, for example: a torque for maintaining a defined position, a torque for returning to a predefined position, or a periodic residual torque.” The Examiner is interpreting the controllable forces as more or less smooth).
With respect to claim 3, Alzingre discloses the angular, width and the length of the non-wound teeth are configured so as to balance radial magnetic forces exerted between the rotor and the teeth of the stator (paragraph 80 “The controllable interaction between the yoke (22) and the second, stationary structure (3) makes it possible to modulate the force applied to the magnetized rotor (18).”).
With respect to claim 4, Alzingre discloses the angular spacing between two consecutive wound teeth is 60 (see figure 11, the angle between the consecutive coils appears to be 60 degrees).
With respect to claim 5, Alzingre discloses the one to three non-wound complementary teeth include three non-wound teeth (4 to 6) separated by an angle of 600 each of the non-wound teeth being diametrically opposite to one of the wound teeth (see figure 11, the angle between the non-wound teeth appears to be 60 degrees).
With respect to claim 6, Alzingre discloses the one to three non-wound complementary teeth include two non-wound teeth located in the second angular sector, an angle defined between each non-wound tooth and the adjacent wound tooth being identical (see figure 11, each non-wound tooth appears to be identically spaced).
With respect to claim 7, Alzingre discloses the stator has a cut-out between the non-wound teeth, a space thin the cut-out is configured to house a magnetically sensitive probe for measuring the position of the rotor (paragraph 95 “In this example, the device according to the present disclosure (DI) is rigidly connected to this user interface and also to a position sensor and it is controlled by a microcontroller”).
With respect to claim 8, Alzingre discloses the one to three non-wound complementary teeth comprises a single non-wound tooth single non-wound tooth (5) being diametrically opposite to a central wound tooth of the three consecutive wound teeth (see figure 11, 3 non-wound teeth are opposed to the motor coils 20).
With respect to claim 9, Alzingre discloses a length of the windings measured radially is less than the a diameter of the rotor (see figures 10-11, radius of the rotor 18 appears larger than that of the coils 20).
With respect to claim 10, Alzingre discloses the stator is made of two or more parts (see at least figure 11, stator is made of a plurality of laminations)
With respect to claim 11, Alzingre discloses a geared motor provided with a housing comprising a three- phase electric motor according to and a movement transformer (fig. 10, motion reduction gear 29).
With respect to claim 12, Alzingre discloses the housing also comprises control electronics configured to control the three-phase electric motor (paragraph 95 “In this example, the device according to the present disclosure (DI) is rigidly connected to this user interface and also to a position sensor and it is controlled by a microcontroller”).
With respect to claim 13, Alzingre discloses the rotor has 2N pairs of magnetic poles, N being a natural number smaller than or equal to 2 (see at least figure 10a, marked below there are at least 8 poles).

With respect to claim 14, Alzingre discloses a shape of the non-wound teeth are configured so as to shape a current-free torque curve of the three-phase electric motor, to favor the regularity and smoothness, or a more or less steep indexing of the current-free torque (see at least figure 11, and paragraph 77 “A device according to the present disclosure makes it possible to introduce a controllable force into an electric motor or actuator by making it possible to add, for example: a torque for maintaining a defined position, a torque for returning to a predefined position, or a periodic residual torque.” The Examiner is interpreting the controllable forces as more or less smooth).
With respect to claim 15, Alzingre discloses a shape of the non-wound teeth is configured so as to balance radial magnetic forces exerted between the rotor and the teeth of the stator (paragraph 80 “The controllable interaction between the yoke (22) and the second, stationary structure (3) makes it possible to modulate the force applied to the magnetized rotor (18).” The Examiner is interpreting controllable as being more or less balanced between the wound and non-wound teeth).
