Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of pre-AIA 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 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Satoh et al US 7,978,027.
Satoh et al discloses a coplanar waveguide filter comprising: a substrate 105;
first and second ground metal plates103 (ground conductor ) each coupled to ground and disposed on a rectangular CPW plane at a top surface of the substrate, wherein the first and second ground metal plates extend continuously from a first end to a second end of the CPW plane along a longitudinal direction of the CPW plane and are positioned on opposite sides of the CPW plane in a transverse direction of the CPW plane, thereby defining a signal region between the first and second ground metal plates, and wherein the signal region extends continuously along the longitudinal direction;
an input signal transmission line (input/output terminal 851) and an output signal transmission line (input/output terminal 852) respectively positioned at two ends of the signal region in the longitudinal direction and each aligned with a first midline, the first midline being a midline of the CPW plane in the longitudinal direction, wherein the input and output signal transmission lines are symmetrically arranged with respect to a second midline, the second midline being a midline of the CPW plane in the transverse direction, wherein the input signal transmission line is separated from the output signal transmission line by a central transverse gap, and wherein a middle signal region is composed of the input and output signal transmission lines and the central transverse gap;
first and second CPW resonators (104a 104b 104e 104d each line conductors) longitudinally arranged between the first ground metal plate and the middle signal region, wherein the first CPW resonator is separated from the second CPW resonator by a first transverse gap, the first transverse gap being aligned with the second midline, and wherein, in the transverse direction, the first and second CPW resonators are separated from the middle signal region by a first longitudinal gap and from the first ground metal plate by a second longitudinal gap; and
third and fourth CPW resonators (104a 104b 104e 104d each line conductors) each longitudinally arranged between the second ground metal plate and the middle signal region, wherein the third CPW resonator is separated from the fourth CPW resonator by a second transverse gap, the second transverse gap being aligned with the second midline, and wherein, in the transverse direction, the third and fourth CPW resonators are separated from the middle signal region by a third longitudinal gap and from the second ground metal plate by a fourth longitudinal gap,
wherein the first and third CPW resonators are symmetrically arranged with respect to the first midline, the second and fourth CPW resonators are symmetrically arranged with respect to the first midline, the first and second CPW resonators are symmetrically arranged with respect to the second midline, and the third and fourth CPW resonators are arranged symmetrically metrical about the second midline.
