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.
Claim(s) 1-7, 9, 11 is/are rejected under 35 U.S.C. 103 as being unpatentable over Shin (6,396,177) in view of Chao (CN 109713817).
As to independent claim 1, Shin teaches an outer rotor structure for a motor, comprising: a sleeve (760), wherein an edge of the sleeve (760) extends toward an axis of the sleeve (760) to form a retaining portion; and a rotor end cover (510), wherein the rotor end cover (510) is nested in the magnetic steel sleeve (760), and the portion (see annotated figure 9) presses against an edge of the rotor end cover (510) to unidirectionally fix the rotor end cover (510) relative to the sleeve (760) in an axis direction as shown in figure 9.
