Office Action

§103
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 § 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. Claim(s) 1, 5 and 10 is/are rejected under 35 U.S.C. 103 as being unpatentable over Ge et al. (CN 113113743 A). As to claim 1, Ge et al.’s figure 2 shows a filter for a communication device comprising: a filter body comprising a cavity that is a dielectric (air) filling space, the cavity having a bottom opened (that is closed by 11); a lower cover panel (11) of a first material, which is coupled to shield the opened bottom of the filter body; and a resonator frame (2 or 22) of a second material (Ge et al. teaches that “the first resonance sheet 21 and the second resonance sheet 22 is a metal sheet structure, in some other examples, also can be gold-plated sheet structure” and “the bottom shell 121 is a metal shell or gold-plated shell”. Therefore, selecting metal sheet structure and gold-plated shell respectively for the resonator and lower cover panel is seen as an obvious design preference to ensure optimum performance),which is coupled to the lower cover panel and comprises a plurality of resonant bars extending in a predetermined length toward a top surface (that contains 122, see figure 8) of the filter body, wherein the resonator frame is formed in the lower cover panel in a way to penetrate an inside and outside of the cavity, and after a bottom of the resonator frame is coupled by being forcibly fit into a plurality of fitting through holes that is spaced apart from each other in a length direction thereof (figure 11) and provided in two columns or more in a width direction thereof (figure 9), surroundings of the plurality of fitting through holes are fixed within the cavity through soldering and coupling (soldering coupling is well known in the art. It would have been obvious to join the shown components with soldering for the purpose of ensuring a strong connection). As to claim 5, selecting the material as claimed is seen as an obvious design preference to ensure optimum performance (copper is a type of metal). As to claim 10, deep drawing press method is well known in the art. It would have been obvious to one having ordinary skill in the art to manufacture the filter body with a deep drawing press method so that a bonding part brought into surface-contact with an end of an edge of the lower cover panel is formed. Allowable Subject Matter Claims 2-4, 6-9 and 11 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
