DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
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.
Specification
The title of the invention is not descriptive. A new title is required that is clearly indicative of the invention to which the claims are directed.
Claim Objections
Claims 38 and 45 are objected to because of the following informalities: claims 38 and 45 depend on cancelled claim 33. Appropriate correction is required.
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.
Claims 27-32, 38-39, and 53 are rejected under 35 U.S.C. 103 as being unpatentable over CN 201078308 Y to Qin et al. in view of US 20090058093 A1 to Bridwell and US 4720640 A to Anderson et al.
Regarding claim 27, Qin et al. discloses a wind turbine comprising:
a first rotor (Fig. 2: 5) comprising a hub (1) and at least one blade (2) extending from the hub, the first rotor configured to rotate as wind engages the at least one blade;
a rotor hub support (4), the first rotor (5) being coupled to the rotor hub support and configured to rotate relative to the rotor hub support;
a tower (3) coupled to the hub (1) via the rotor hub support (4) and configured to support the first rotor, wherein a longitudinal axis of the tower (vertical) is perpendicular to a longitudinal axis of the hub (horizontal);

a first generator configured to generate electrical power from rotation of the first rotor, the first generator comprising at least one magnet (7) and a conductor coil (14),
wherein one of the at least one magnet and conductor coil is coupled to the first rotor and configured to rotate therewith (magnet 7 is coupled to rotor ring 6), and the other one of the at least one magnet and the conductor coil is fixed relative to the frame (coil 14 fixed to frame at 13), such that rotation of the first rotor causes relative movement between the conductor coil and the at least one magnet.
However, it fails to disclose a second rotor configured to rotate in an opposed direction to a direction of rotation of the first rotor; and a second generator configured to generate electrical power on rotation of the first rotor relative to the rotor hub support, the second generator comprising at least one magnet and a conductor coil, wherein one of the at least one magnet and conductor coil of the second generator is coupled to the first rotor and configured to rotate therewith, and the other of the at least one magnet and the conductor coil of the second generator is fixed to the rotor hub support, such that rotation of the first rotor causes relative movement between the conductor coil and the at least one magnet of the second generator.
