Claim Rejections - 35 USC § 102
In the event the determination of the status of the application as subject to AIA  35 U.S.C. 102 and 103 (or as subject to pre-AIA  35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA  to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
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)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claim(s) 1-18 is/are rejected under 35 U.S.C. 102a1 as being anticipated by Kagiya (JP 2000249107).
Kagiya discloses the limitations in the claims below:
1, 10. A pneumatic actuator (See fig. 2-3), comprising: a housing 11; an actuator shaft 13 disposed within the housing and configured to actuate between a first position and a second position (Fig. 2-3); and a single bushing 17 located within the housing between the housing and the actuator shaft, wherein the single bushing is configured to support the actuator shaft 13 without the actuator shaft being supported at a second location while allowing actuator motion under set operating conditions, the actuator actuates a crank (Fig. 5 23a, 23b, 23c).
2, 11. The actuator of claim 1, wherein the actuator shaft includes a pneumatic cup at a first end, and a drive connection assembly at a second end (12b with 12 and the connection drive at left end of 13 – Fig. 2).
3-4, 12-13. The actuator of claim 2, wherein the bushing includes a length to diameter ratio of greater than 1, wherein the length to diameter ratio is between 2 and 3. (Clearly shown in Fig. 1).

6, 15. The actuator of claim 5, wherein the bushing has a length of about a third of the shaft length (shown in Fig. 2).
7, 16. The rejection applied above to the limitations regarding a slotted crank shaft in claim 19 are applied mutatis mutandis to the limitations in claim 7 and 16.
8-9, 17-18. The actuator of claim 7, (The feature of the formula of claim 8 and 17 to be solved for and defining the length x2-x1 of an inner diameter of the bushing between two contact points by the actuator shaft when actuating by the actuator to force a crank to achieve a required crank force, is merely a known formula resulting from the equilibrium of moments by the respective forces and geometric properties and layout of the actuator shaft, bushing and slotted crank mechanism).
Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA  35 U.S.C. 102 and 103 (or as subject to pre-AIA  35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA  to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
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) 19-20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Kagiya (JP 2000249107).
19-20.Kagiya discloses A pneumatic actuator (See fig. 2-3), comprising: a housing 11; an actuator shaft 13 disposed within the housing and configured to actuate between a first position and a second position (Fig. 2-3); and a single bushing 17 located within the housing between the housing and the actuator shaft, wherein the single bushing is configured to support the actuator shaft 13 without the actuator shaft being supported at a second location while allowing actuator motion under set operating conditions, the actuator actuates a crank (Fig. 5 23a, 23b, 23c) further comprising selecting dimensions of the bushing to allow actuation of the actuator shaft under a set operating actuator force (inherent in the operation of the actuator).
Although Kagiya does not specifically disclose a slotted crank to be driven, It would have been obvious design choice for one having ordinary skill in the art at the time the invention and with a reasonable expectation of success to us an obvious variant of the crank shaft to an equivalent mechanism to drive rotary motion from linear motion, since it has been held that broadly providing an equivalent means which accomplishes the same result involves only routine skill in the art. In this case it would have been obvious in order to provide a reduced weight shaft.
