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 4-5 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. Regarding Claim 4: Claim 4 recites “a heat capacity of a portion with a melting point greater than or equal to 1,200 °C.” It is not clear if the heat absorbing portion is required to contain a portion with a melting point greater than or equal to 1,200 °C or if the claim simply limits the heat capacity of any portion that happens to have a melting point greater than or equal to 1,200 °C. Regarding Claim 5: Claim 5 recites the limitation "the refrigerant circuit" and “the device” in lines 1 and 2 respectively. There is insufficient antecedent basis for these limitations in the claim. Response to Arguments Applicant's arguments filed June 2, 2026 have been fully considered and sufficiently addressed in the new grounds of rejection as set forth above.
