Office Action

§112
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 § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: 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 32, 36, 52, 53 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 32 recites the limitation “the quasi-periodic wave structures” in line 22. There is insufficient antecedent basis for this limitation in the claim. Claim 32 recites “in particular within the inverse cones…” The phrase “in particular” makes the claim unclear. Claim 36 recites in lines 3-4 “for each wavelength in the partial range in a partial range of the electromagnetic spectrum.” The recitation is not clear. Claim 52 recites the limitation “the quasi-periodic wave structure” in lines 1-2. There is insufficient antecedent basis for this limitation in the claim. Claim 52 recites the limitation “the structural features” in line 3. There is insufficient antecedent basis for this limitation in the claim. Claim 53 recites the limitation “the quasi-periodic wave structure” in lines 1-2. There is insufficient antecedent basis for this limitation in the claim. Claim Objections Claim 41 is objected to under 37 CFR 1.75 as being a substantial duplicate of claim 32. When two claims in an application are duplicates or else are so close in content that they both cover the same thing, despite a slight difference in wording, it is proper after allowing one claim to object to the other as being a substantial duplicate of the allowed claim. See MPEP § 608.01(m). Claim 42 is objected to under 37 CFR 1.75 as being a substantial duplicate of claim 32. When two claims in an application are duplicates or else are so close in content that they both cover the same thing, despite a slight difference in wording, it is proper after allowing one claim to object to the other as being a substantial duplicate of the allowed claim. See MPEP § 608.01(m). Examiner’s Note Claims 32-47, 52, and 53 would be allowable on the merits if the claims rejected under 35 USC 112(b) are amended. The following is a statement of reasons for the indication of allowable subject matter: the closest prior art Iwata and Sebastian fail to teach or suggest the patterned substrate of claim 32. Conclusion THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
