Office Action

§101 §DP
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application is being examined under the pre-AIA first to invent provisions. Double Patenting A rejection based on double patenting of the “same invention” type finds its support in the language of 35 U.S.C. 101 which states that “whoever invents or discovers any new and useful process... may obtain a patent therefor...” (Emphasis added). Thus, the term “same invention,” in this context, means an invention drawn to identical subject matter. See Miller v. Eagle Mfg. Co., 151 U.S. 186 (1894); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Ockert, 245 F.2d 467, 114 USPQ 330 (CCPA 1957). A statutory type (35 U.S.C. 101) double patenting rejection can be overcome by canceling or amending the claims that are directed to the same invention so they are no longer coextensive in scope. The filing of a terminal disclaimer cannot overcome a double patenting rejection based upon 35 U.S.C. 101. Claim 1 is/are rejected under 35 U.S.C. 101 as claiming the same invention as that of claim 1 of prior U.S. Patent No. 11,475,325. This is a statutory double patenting rejection. Claim of the present application Claim of Patent No. 11,474,325 An interchangeable lens attachable to a camera body, the interchangeable lens comprising: a focusing optical system configured to vary a focal position of the interchangeable lens; a detector configured to detect a position of the focusing optical system on an optical axis of the interchangeable lens; and a transmitter configured to transmit a first value and a second value to the camera body, the first value indicating a first relationship between an amount of movement of the focusing optical system and an amount of movement of an image plane and being determined based on the position of the focusing optical system detected by the detector, the second value indicating a second relationship between the amount of movement of the focusing optical system and the amount of movement of the image plane, the second value being a minimum value of the second first relationship between the amount of movement of the focusing optical system and the amount of movement of the image plane, when the position of the focusing optical system detected by the detector is a first position, the first value is larger than the second value, and when the position of the focusing optical system detected by the detector is a second position, the first value is equal to the second value, wherein the first value is a first coefficient corresponding to TI/TL where the TL is the amount of movement of the focusing optical system and the TI is the amount of movement of the image plane. An interchangeable lens attachable to a camera body, the interchangeable lens comprising: a focusing optical system configured to vary a focal position of the interchangeable lens; a detector configured to detect a position of the focusing optical system on an optical axis of the interchangeable lens; and a transmitter configured to transmit a first value and a second value to the camera body, the first value indicating a first relationship between an amount of movement of the focusing optical system and an amount of movement of an image plane and being determined based on the position of the focusing optical system detected by the detector, the second value indicating a second relationship between the amount of movement of the focusing optical system and the amount of movement of the image plane, the second value being a minimum value of the first relationship between the amount of movement of the focusing optical system and the amount of movement of the image plane, when the position of the focusing optical system detected by the detector is a first position, the first value is larger than the second value, and when the position of the focusing optical system detected by the detector is a second position, the first value is equal to the second value, wherein the first value is a first coefficient corresponding to Tl/TL, where the TL is the amount of movement of the focusing optical system and the Tl is the amount of movement of the image plane.
