Claim Rejections - 35 USC § 102
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.
Claims 1-3 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Takeshi, Japanese Patent JP2008205210A.
Regarding Claim 1, Takeshi teaches, a transformer unit (Fig. 4), comprising a primary side coil (21, 22, 24, 25, 27, 28) and a secondary side coil (23, 26) that are arranged to face each other in a winding axis direction, wherein
one of the primary side coil and the secondary side coil is formed by metal plate winding bodies (“metal plate-winding type coils” [0030]) each formed of a wound metal plate,
the other of the primary side coil and the secondary side coil includes a first winding and a second winding (23, 26) having a greater number of turns than the metal plate winding bodies,
each of the metal plate winding body, the first winding, and the second winding is wound around a winding axis extending in the winding axis direction (Fig. 4), and
the first winding and the second winding (23, 26) are disposed on opposite sides of the metal plate winding bodies (24, 25) in the winding axis direction, the number of the metal plate winding bodies (two) being equal to a combined number of the first winding and the second winding (two). (Takeshi: Figs. 1-6, machine translation, para. [0029]-[0031]).
Regarding Claim 2, Takeshi further teaches, wherein each of the first winding and the second winding (23, 26) includes multiple windings that are connected in parallel (“formed into a ring shape by winding two parallel core wires” [0030]). (Takeshi: Fig. 5, machine translation, para. [0030]).
Regarding Claim 3, Takeshi further teaches, wherein the transformer unit (80) (Fig. 4) is configured to be used in a push-pull power conversion device (transformer 80 is capable of being configured as a push-pull conversion device since it is disclosed at least as “a switching power supply such as a power module power supply or an on-board power supply” [0039]),
and the first winding and the second winding (23, 26) are disposed on opposite sides of both of the two metal plate winding bodies (24, 25) in the winding axis direction. (Takeshi: Figs. 1-6, machine translation, para. [0029]-[0031], [0039]).
