Claim(s) 1, 2, 4 is/are rejected under 35 U.S.C. 102a1 as being anticipated by ISHIKAWA (2007/0037645) Regarding Claim 1, ISHIKAWA teaches A derailleur for a human-powered vehicle, the derailleur (97r)(97f)[0032] comprising: a base member (12f) configured to be attached to a vehicle body (90) of the human-powered vehicle; a movable member (14f) configured to be movable relative to the base member in a first direction and a second direction different from the first direction; a linkage (16a)(16b) configured to movably connect the movable member (14f) to the base member (12f); an electrical actuator (125f) configured to operatively move the movable member (14f) relative to the base member (12f), the electrical actuator (125f) being configured to receive electricity from a generator [0032] mounted to a hub assembly to generate electricity using a rotation of a wheel; a capacitor [0032] directly mounted to the derailleur, the capacitor being electrically connected to the electrical actuator (125f); and a saver member (18c) pivotally coupled to at least one of the base member, the movable member, the linkage (16b)(16a), and the electrical actuator. Regarding Claim 2, ISHIKAWA teaches wherein the capacitor [0032] is not directly mounted to the linkage (16b)(16a). Regarding Claim 4, ISHIKAWA teaches further comprising a controller (127f) configured to be powered by the capacitor and the generator [0032]. 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) 3 is/are rejected under 35 U.S.C. 103 as being unpatentable over ISHIKAWA (2007/0037645) in view of KITAMURA (2005/0285461) Regarding Claim 3, ISHIKAWA does not teach further comprising a connector configured to be electrically connected to the generator. KITAMURA teaches further comprising a connector (66)(67) configured to be electrically connected to the generator. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to change the derailleur and generator in ISHIKAWA so it has the connector in KITAMURA so the two devices can be easily connected and disconnected from each other for servicing or replacement. Claim(s) 5-14, 16-20 is/are rejected under 35 U.S.C. 103 as being unpatentable over ISHIKAWA (2007/0037645) in view of FUKUDA (2004/0102270) Regarding Claim 5, ISHIKAWA does not teach further comprising: a first biasing member configured to deform if first external force is applied to move the movable member in the first direction; and a second biasing member configured to deform if second external force is applied to move the movable member in the second direction. FUKUDA teaches further comprising: a first biasing member (712)(632) configured to deform if first external force is applied to move the movable member in the first direction; and a second biasing member (704) configured to deform if second external force is applied to move the movable member in the second direction. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to change the derailleur in ISHIKAWA so it has the biasing member arrangement in FUKUDA to protect the derailleur from damage due to impacts from either the left or right side of the chain guide. Regarding Claim 6, ISHIKAWA as modified teaches wherein the electrical actuator includes an output part configured to be operatively coupled to the movable member (14f) to move the movable member relative to the base member (12f), the first biasing member (FUKUDA 712) is configured to reduce the first external force transmitted to the output part, and the second biasing member (FUKUDA 704) is configured to reduce the second external force transmitted to the output part. Regarding Claim 7, ISHIKAWA as modified teaches wherein the first biasing member (FUKUDA 712) is configured to allow the movable member to move relative to the base member in the first direction in response to the first external force, and the second biasing member (FUKUDA 704) is configured to allow the movable member to move relative to the base member in the second direction in response to the second external force. Regarding Claim 8, ISHIKAWA as modified teaches wherein the first biasing member (FUKUDA 712) includes a first end and a first opposite end, and the first end of the first biasing member is operatively coupled to the output part (FUKUDA 452) of the electrical actuator.
