Office Action

§102
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 . 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) 1-15 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Ryu et al. (US 2013/0249391, cited by the applicant). Re claim 1: Ryu teaches an integrated ultrawideband pulse generator for high-power electromagnetic pulse radiation comprising an outer casing (200) having openings (i.e., a space S) formed on both sides; a pair of electrodes (210, 220) serving as a pair of antenna bodies installed to adhere to an inner side of the openings on both sides of the outer casing (i.e., the brackets 230 and 240) (paragraphs 0046, 0054) wherein a pair of directional electrodes also serving as the pair of antenna bodies and facing each other at a predetermined spacing inside the outer casing (fig. 3); and a pair of covers (i.e., a top and a bottom cover) for sealing the openings on both sides of the outer casing (see figs. 3, 4; paragraphs 0042-0058). Re claim 2: Wherein the pair of directional electrodes are fabricated such that facing surfaces thereof form an exponential shape, a linear shape, or a spherical shape when viewed from a side (fig. 5). Re claim 3: Wherein, in the pair of directional electrodes, a spark generation area (i.e. an area around the electrode assisting members (212, 222)) on the facing surfaces is fabricated to form a flat or curved surface (fig. 4). Re claim 4: Wherein the pair of directional electrodes include electrode protrusions (213) attached to a spark generation area on the facing surfaces (fig. 4). Re claim 5: Wherein edges of the pair of directional electrodes are fabricated with a blended structure (paragraph 0052). Re claim 6: Wherein: the pair of directional electrodes are fabricated with an aluminum material (paragraph 0052), and a spark generation area is fabricated with a material (212, 222) including one of copper, tungsten, copper-tungsten, and molybdenum (paragraph 0051). Re claim 7: Wherein a size and spacing of the pair of directional electrodes are set depending on a frequency and a discharge voltage (i.e., the electrodes 210 220) generate ultra-wideband electromagnetic pulses or frequency and the diameter of the electrode protrusion (213) depends on diameter of the electrode (210 or 220), paragraphs 0046-0048). Re claim 8: Ryu teaches an integrated ultrawideband pulse generator for high-power electromagnetic pulse radiation, configured to radiate a high-voltage ultrawideband pulse when high-voltage pulse power is applied (paragraph 0046) comprising a pair of directional electrodes (210, 220) facing each other at a predetermined spacing (see figs. 3, 4; paragraphs 0042-0058). Re claim 9: The integrated ultrawideband pulse generator further comprising: an outer casing (200) having openings (i.e., a space S) formed on both sides; a pair of electrodes (210, 220) serving as a pair of antenna bodies installed to adhere to an inner side of the openings on both sides of the outer casing (paragraph 0046); and a pair of covers (i.e., a top and a bottom cover) for sealing the openings on both sides of the outer casing (fig. 3). Re claim 10: Wherein the pair of directional electrodes are fabricated such that facing surfaces thereof form an exponential shape, a linear shape, or a spherical shape when viewed from a side (fig. 5). Re claim 11: Wherein, in the pair of directional electrodes, a spark generation area (i.e. an area around the electrode assisting members (212, 222)) on the facing surfaces is fabricated to form a flat or curved surface (fig. 4). Re claim 12: Wherein the pair of directional electrodes include electrode protrusions (213) attached to a spark generation area on the facing surfaces (fig. 4). Re claim 13: Wherein edges of the pair of directional electrodes are fabricated with a blended structure (paragraph 0052). Re claim 14: Wherein: the pair of directional electrodes are fabricated with an aluminum material (paragraph 0052), and a spark generation area is fabricated with a material (212, 222) including one of copper, tungsten, copper-tungsten, and molybdenum (paragraph 0051). Re claim 15: Wherein a size and spacing of the pair of directional electrodes are set depending on a frequency and a discharge voltage (i.e., the electrodes 210 220) generate ultra-wideband electromagnetic pulses or frequency and the diameter of the electrode protrusion (213) depends on diameter of the electrode (210 or 220), paragraphs 0046-0048).
