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, 3-18 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 1,17,18, “exterior air” is indefinite as it is unclear what exterior refers to. It is believed the exterior air means ambient air.
Subsequent dependent claims are further rejected.
Regarding claim 3 and 9, “upside the first heat exchange part” is indefinite as it is unclear what upside refers to. It is also unclear if “circulation line” is the same as the “recirculation line”.
Regarding claim 8, “fuel having passed via the first heat exchange part” is indefinite as it is unclear when the fuel passes through the first heat exchange part, claim 3 claims it going through “the second heat exchange part”.
Regarding claim 12 and 18, “ejection nozzle connected to an outlet end” is indefinite as it is unclear what the outlet end is for.
Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
