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 1-6 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. Regarding claim 1, the recitation of “the cyclone dust collector is connected to the plastic drying barrel to suck out and filter the air…” is indefinite because it is unclear what applicant intends. The claim recites different filters and it is unclear if the cyclone dust collection is providing the filtering function or one of the previously recited filters. Clarification and correction are both required to more clearly recite the function of the cyclone dust collector and the filtering function. Claim 1 recites the limitation "the manufacturing process" in line 25. There is insufficient antecedent basis for this limitation in the claim. Claim 1 recites the limitation "the imbalance" in line 28. There is insufficient antecedent basis for this limitation in the claim. Claim 1 recites the limitation "the atmosphere" in line 29. There is insufficient antecedent basis for this limitation in the claim. Claim 1 recites the limitation "the above structure" in line 45. There is insufficient antecedent basis for this limitation in the claim. Claim 1 recites the limitation "the temperature difference" in line 46. There is insufficient antecedent basis for this limitation in the claim. Claim 1 recites the limitation "the dew condensation" in line 47. There is insufficient antecedent basis for this limitation in the claim. Claim 1 recites the limitation "the humid air " in line 47. There is insufficient antecedent basis for this limitation in the claim. Claim 1 recites the limitation "the effect" in line 48. There is insufficient antecedent basis for this limitation in the claim. Claims 2-6 are rejected based on their dependency on rejected claim 1. The following is a quotation of 35 U.S.C. 112(d): (d) REFERENCE IN DEPENDENT FORMS.—Subject to subsection (e), a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. The following is a quotation of pre-AIA 35 U.S.C. 112, fourth paragraph: Subject to the following paragraph [i.e., the fifth paragraph of pre-AIA 35 U.S.C. 112], a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. Claims 3-6 are rejected under 35 U.S.C. 112(d) or pre-AIA 35 U.S.C. 112, 4th paragraph, as being of improper dependent form for failing to further limit the subject matter of the claim upon which it depends, or for failing to include all the limitations of the claim upon which it depends. Independent claim 1 recites an apparatus/device and associated features, and claims 3-6 recite intended use operations with no additional structure and/or structural configurations to further limit the claimed device. Claims directed to apparatus must be distinguished from the prior art in terms of structure rather than function. In re Danly, 263 F.2d 844, 847, 120 USPQ 528, 531 (CCPA 1959). “[A]pparatus claims cover what a device is, not what a device does.” Hewlett-Packard Co. v. Bausch & Lomb Inc., 909 F.2d 1464, 1469, 15 USPQ2d 1525, 1528 (Fed. Cir. 1990). (emphasis in original) Applicant may cancel the claim(s), amend the claim(s) to place the claim(s) in proper dependent form, rewrite the claim(s) in independent form, or present a sufficient showing that the dependent claim(s) complies with the statutory requirements. Allowable Subject Matter Claims 1-6 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action.
