2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
Claim 1,2,9,10,13 are rejected under 35 U.S.C. 103 as being unpatentable over Numomura (Japanese Patent Publication JP2011193573A hereinafter “Numomura”) in view of Shinoda (Japanese Patent Document JP2010279131a hereinafter “Shinoda”) OR Motoishi et al. (US PG Pub 20230412030 hereinafter “Motoishi”).
Re-claim 1, Numomura discloses an electrical insulator (64) configured to be fitted onto a radially extending tooth (56) of a stator core (51), the tooth having a first outer wall surface (annotated fig.13b) axially spaced from a second outer wall surface (annotated fig.13b), and a third outer wall surface (annotated fig.13b) circumferentially spaced from a fourth outer wall surface (annotated fig.13b), the electrical insulator (64) including a tooth insertion hole (inside 64) in which the tooth (56) is configured to be received (inside 64), the electrical insulator (64) being configured to be mounted on the tooth (56) and restrained from moving relative to the tooth (by 65,67,66), the electrical insulator including an inner wall (64a) defining the tooth insertion hole (inside 64) and at least two projections (66) that protrude from the inner wall into the tooth insertion hole (see fig.13a), the inner wall (64a) including a first inner wall surface (annotated fig.13a) configured to face the first outer wall surface of the tooth (annotated fig.13b), a second inner wall surface (annotated fig.13a) configured to face the second outer wall surface (annotated fig.13b) of the tooth (56), a third inner wall surface (annotated fig.13a) configured to face the third outer wall surface (annotated fig.13b) of the tooth and a fourth inner wall surface (annotated fig.13a) configured to face the fourth inner wall surface (annotated fig.13b) of the tooth in a state in which the tooth is in the tooth insertion hole (annotated fig.13b), and the inner wall including the at least one set of projections (66) selected from a group consisting of a first set of projections located on the first inner wall surface and the second inner wall surface and a second set of projections (66) located on the third inner wall surface and the fourth inner wall surface (see fig.13 a and b, projection 66), the first set of projections including at least one first projection formed on the first inner wall surface and at least one second projection formed on the second inner wall surface, and the second set of projections including at least one third projection formed on the third inner wall surface and at least one fourth projection surface (see fig.13 a and b, projection 66), formed on the fourth inner wall surface, wherein the electrical insulator (64) is configured to be restrained from moving relative to the tooth (56) by abutment between the first and second outer wall surfaces of the tooth and the projections of the first set of projections and/or by abutment (66 is inside of 67) between the third and fourth outer wall surfaces (annotated fig.12) of the tooth (56) and the projections of the second set of projections (66).
Numomura is silent that the insulator is an “electrical” insulator.
However, Shinoda teaches that the insulator (bobbin 5) is an electrical insulator (Provides electrical insulation, P[0023]).
Therefore, it is obvious to one with ordinary skill in the art before the effective filling date of the invention to modify the insulator of Numomura and explicitly state it is an electrical insulator as mentioned by Shinoda to provide electrical insulation between windings and core preventing contact, (Shinoda, P[0005]).

Motoishi teaches that the insulator (bobbin 9a) is an electrical insulator (P[0086]).
Therefore, it is obvious to one with ordinary skill in the art before the effective filling date of the invention to modify the insulator of Numomura and explicitly state it is an electrical insulator as mentioned by Motoishi to provide electrical insulation between core and coils and minimize short circuit, providing a reliable circuit and device (Motoishi, P[0086]).
Re-claim 2, Numomura as modified discloses the electrical insulator as defined in claim 1, including the second set of projections (66).
Re-claim 9, Numomura as modified discloses the electrical insulator as defined in claim 2,
Numomoura fails to explicitly teach wherein the projections include the first set of projections.
However, Shinoda teaches that the projections (5f) includes the first set of projections (5f, see fig from Shinoda).
Therefore, it is obvious to one with ordinary skill in the art before the effective filling date of the invention to modify the insulator of Numomura wherein the projections include the first set of projections as shown by Motoishi to provide holding structure and prevent rattling of coils (Shinoda, P[0031]).
Re-claim 10, , Numomura as modified teach the electrical insulator as defined in claim 1, wherein the projections include the first of projections (66).
Re-claim 13, Numomura as modified discloses a motor (title), having a stator (5) and a rotor (4), the stator (5) including a stator core (51), electrical insulators (bobbins 70) and one or more stator windings (coil 52), the stator core being tubularly (see fig.2a showing tubular, rounding 57) composed of electromagnetic steel sheets (58, tubular portions) laminated in an axial direction (see fig.1, shwonig 58 stacked axially) and having a yoke (57) extending in a circumferential direction (around rotor) and teeth (56) extending radially inward from the yoke (see fig.2a), the electrical insulators (70) being respectively fitted onto the teeth, the stator winding (52) being wound around the electrical insulators (64, coil bobbin) fitted onto the teeth (56), wherein: each of the electrical insulators (70,64) comprises the electrical insulator (65) as defined in claim 1.
Claim 14 are rejected under 35 U.S.C. 103 as being unpatentable over Numomura in view of Shinoda OR Motoishi and in further view of Jeong et al (US Patent 11909296 hereinafter “Jeong”).
Re-claim 14, Numomura as modified the motor comprises the motor as defined in claim 13.
Numomura fails to explicitly teach discloses the compressor, having a compression mechanism part for compressing a working medium and a motor for driving the compression mechanism part.
However, Jeong teaches discloses the compressor (100), having a compression mechanism part (120) for compressing a working medium (compresses gaseous medium, air, col.4, L.45-60) and a motor (130) for driving the compression mechanism part (120).
Therefore, it would have been obvious to one with ordainry skill before the effective filling date of the invention to modify the device of Numomura such that is used in the compressor, having a compression mechanism part for compressing a working medium and a motor for driving the compression mechanism part as suggested by Jeong to use the device for cooling system and provide cooling (Jeong, Col.6, L.43-52).
