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. Claims 1-20 are rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor, or for pre-AIA the applicant regards as the invention. Regarding Claim 1, the limitation “the third port, the fourth port, the fifth port and the sixth port are configured such that a first fluid flows in the heat exchange assembly through the third port and flows out of the heat exchange assembly through the fourth port, the fifth port and the sixth port, respectively” is indefinite, in context, since it cannot be discerned in what flow configuration the fluid flows out of the heat exchange assembly from the sixth port, wherein figure 5 shows fluid flowing into the heat exchange assembly from the sixth port. For Examination purposes and in accordance with the specification and drawings, “the third port, the fourth port, the fifth port and the sixth port are configured such that a first fluid flows in the heat exchange assembly through the third port and flows out of the heat exchange assembly through the fourth port, the fifth port and the sixth port, respectively” will be interpreted as –the third port, the fourth port, the fifth port and the sixth port are configured such that a first fluid flows into the heat exchange assembly through the third port and sixth port and flows out of the heat exchange assembly through the fourth port and fifth port--. Allowable Subject Matter Claims 2-20 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). 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.
