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 Objections Claims 2-6, 8-9 are is objected to because of the following informalities: claims 2-6, 8-9, “,” shall be changed to --. -- to finish the sentence. Appropriate correction is required. Claims 4-11 are objected to under 37 CFR 1.75(c) as being in improper form because a multiple dependent claim cannot depend from any other multiple dependent claim. See MPEP 608.01(n). Accordingly, the claim has (these claims have) not been further treated on the merits. 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 1-11 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 1-11 are indefinite because the preamble purports to define a process for drying clothing or other objects. However, the body of claims recites only structural limitations and failed to include any active, positive method steps to define a drying process. The phrases “it”, “its” in claims 1-2, 5-10; “fast, effectively, and energy-efficiently” in claim 1; “an energy-efficient, effective, and sustainable way” in claim 2 render the claims indefinite. It is unclear what the phrases “it” and “its” mean. It is also unclear which way is an energy-efficient, effective and sustainable way. The phrase “(article weight, hot air pressure and temperature, energy consumed, etc)” in claim 11 renders the claim indefinite because the claim(s) include(s) elements not actually disclosed (those encompassed by “(article weight, hot air pressure and temperature, energy consumed, etc)”), thereby rendering the scope of the claim(s) unascertainable. See MPEP § 2173.05(d). Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Rensing et al. (US 2021/0372036 A1) discloses a laundry drying systems comprising sensors for sensing moisture, temperature and laundry weight. Xu et al. (CN 103820980 A) discloses a dryer comprising pressure sensor, compressor, condenser, heat exchanger and liquid collector (Figs. 1-5). Tuncel et al. (WO 2004/111327 A1) discloses a laundry dryer using microwave from a magnetron producing microwave energy for drying clothes (abstract). Smith (US 5,396,715) discloses a microwave clothes dryer comprising magnetron, valves and nozzles. (Fig. 1).
