Office Action

§112
DETAILED ACTION 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 2-5 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. Claims 2-3 are indefinite because the “fluorine-containing ethylenic copolymer” has no antecedent basis. Note that only fluorine polymer is recited in claim 1 upon which claims 2-3 depend. Claims 4-5 are deemed indefinite in view of their dependency on claim 1. Allowable Subject Matter Claims 1 and 6-12 are allowed. The following is a statement of reasons for the indication of allowable subject matter: None of the prior art references of record teach or suggest a powder coating comprising carbon nanotube present in an amount of 0.01 to 0.35 mass% based on the total amount of the electroconductive material, which includes the carbon nanotube, and a fluorine-containing ethylenic polymer. As shown in the instant specificatwion, when the amount of carbon nanotube exceeds 0.35 mass%, the coating cannot be formed.
