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 1. 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. Claim 6-13, 25, 27, 37 and 48 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 pre-AIA the applicant regards as the invention. Claim 6, recites the limitation of “the inlet air stream being characterized by a first parameter and a second parameter” which is confusing as it is unclear what constitute “characterized by a first parameter and a second parameter” as recited in the claim. As such the claim limitation is indefinite. Claim 7, recites the limitation "the signal indicative of a temperature and a humidity of the supply air stream measured by the sensor” in lines 3-4. There is insufficient antecedent basis for this limitation in the claim. Claim 7, recites the limitation “a first parameter and a second parameter associated with the supply air stream”, in lines 5-6; is confusing as it is unclear how it relates to previously recited “a first parameter and a second parameter” in claim 6, line 3. Claim 8, lines 2-3, the term “less than about 4 percent” is a relative term which renders the claim indefinite. The term “less than about 4 percent” is not defined by the claim, the specification does not provide a standard for ascertaining the requisite degree, and one of ordinary skill in the art would not be reasonably apprised of the scope of the invention. Claim 9, lines 2-3, the term “less than about 2 percent” is a relative term which renders the claim indefinite. The term “less than about 2 percent” is not defined by the claim, the specification does not provide a standard for ascertaining the requisite degree, and one of ordinary skill in the art would not be reasonably apprised of the scope of the invention. Claim 10, lines 2-3, the term “less than about 0.5 percent” is a relative term which renders the claim indefinite. The term “less than about 0.5 percent” is not defined by the claim, the specification does not provide a standard for ascertaining the requisite degree, and one of ordinary skill in the art would not be reasonably apprised of the scope of the invention. Claim 11, line 3, the term “less than about 0.6 BTU/lbs” is a relative term which renders the claim indefinite. The term “less than about 0.6 BTU/lbs” is not defined by the claim, the specification does not provide a standard for ascertaining the requisite degree, and one of ordinary skill in the art would not be reasonably apprised of the scope of the invention. Claim 12, line 3, the term “less than about 0.3 BTU/lbs” is a relative term which renders the claim indefinite. The term “less than about 0.3 BTU/lbs” is not defined by the claim, the specification does not provide a standard for ascertaining the requisite degree, and one of ordinary skill in the art would not be reasonably apprised of the scope of the invention. Claim 13, line 3, the term “less than about 0.06 BTU/lbs” is a relative term which renders the claim indefinite. The term “less than about 0.06 BTU/lbs” is not defined by the claim, the specification does not provide a standard for ascertaining the requisite degree, and one of ordinary skill in the art would not be reasonably apprised of the scope of the invention. Claim 25, line 3, calls for the limitation of the "eliminated or reduced substantially”; this phrase renders the claim indefinite because the meaning of “substantially” is unclear and potentially could lead to multiple interpretations; the specification does not provide a standard for ascertaining the requisite degree, and one of ordinary skill in the art would not be reasonably apprised of the scope of the invention. Claim 27, recites the limitation "the signal indicative of a temperature and a humidity of the supply air stream measured by the sensor” in line 5. There is insufficient antecedent basis for this limitation in the claim. Claim 37, line 2, recites the limitation "another system”. It is unclear what constitutes “another system”. Claim 48, calls for the limitation of absolute humidity which is confusing; the specification does not provide any range or volume of air for this. Conclusion 2. The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. US-11761644-B1 to Qasem; Naef A. A. . US-20190184334-A1 to MOGHADDAM; Saeed.
