Office Action

§103 §112
DETAILED ACTION Claim Rejections - 35 USC § 112 The following is a quotation of the second paragraph of 35 U.S.C. 112: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 4 and 7 are rejected under 35 U.S.C. 112, second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which applicant regards as the invention. In claim 4, line 4, the language, “the antenna connection box” lacks an antecedent basis. In claim 7, line 3, the language, “the means of insertion and extraction” lacks an antecedent basis. Claim Objections Claims 1-10 are objected to because of the following informalities: Throughout the claims, a period “.” is not allowed at the middle of a claim, see (for example, claim 1, line 6, “ends.”). In claim 1, lines 9 and 10, “the” should inserted before – director bars--. In claim 1, line 12, “that” should be deleted. In claims 2 and 3, line 1, “number” should be deleted. In claim 6, line 1, “number” should be deleted. 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 1-10 are rejected under 35 U.S.C. 103(a) as being unpatentable over the publication of EP 2093838 A1. Regarding claim 1, the publication of EP 2093838 A1 teaches a Yagi-type multiband antenna (para10) comprising a dipole 13 connected to an input/output cable of the antenna (fig1), a plurality of n director bars 1,2,3, each of the director bars designed for a frequency band, fastening and supporting means 4,5 to which the director bars are joined at one of their ends, the dipole is designed for a bandwidth comprising the multiband (para19), the director bars are at distances from each other (fig1), the director bars form angles with one another (fig1, para18). Regarding claims 2-10, the publication of EP 2093838 A1 further teaches the insertion and extraction means are implicitly disclosed as the director bars are implicitly inserted and extracted in the device; the fastening and supporting means are integrated with the antenna connection box (fig4, paras29-30); at least one of the means of insertion and extraction of the director bars being attached to the reflectors 6; means to configure the distance or the angle are implicitly disclosed in the publication of EP 2093838 A1, as the distance or the angle have been configured at the assembly stage; at least three director bars (fig1) and a filter C1-C15 between the dipole and the output cable (fig5). The publication of EP 2093838 A1 had been discussed but fails to expressly teach at least two director bars are designed for different frequency bands. However, the publication of EP 2093838 A1 discloses the directors bars 1,2,3 have different lengths therefore would provide different frequency bands. It would have been obvious before the effective filing date of the claimed invention to a person having ordinary skilled in the art to provide the publication of EP 2093838 A1 with at least two director bars are designed for different frequency bands for the purpose of improving the antenna gain. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. The patents to Timofeev, Chen, Wright, Eckwielen, Van Buren and Berkowitz are cited as of interested and illustrated a similar structure to a Yagi-type multiband antenna.
