CTNF 18/458,901 CTNF 80859 Notice of Pre-AIA or AIA Status 07-03-aia AIA 15-10-aia 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 § 101 07-04-01 AIA 07-04 35 U.S.C. 101 reads as follows: Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title. Claims 1-14 are rejected under 35 U.S.C. 101 because the claimed invention is directed to an abstract idea without significantly more. The claim(s) (1,13,14) recite(s) acquire an environmental sound, calculate colorability and variation in frequency spectrum intensity, and determine whether or not the environmental sound includes the operating sound by comparing. This judicial exception is not integrated into a practical application because acquire, calculate and determine can be done by general computer. The claim(s) does/do not include additional elements that are sufficient to amount to significantly more than the judicial exception because acquiring sound, calculate colorability and frequency, and determines whether or not, which is just a mathematical relationship. With respect to claim 14, the sound collection units, elevator car, and processing circuitry are not abstract, how they do not integrate the method into practical application. Claim Rejections - 35 USC § 112 07-30-02 AIA 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. 07-34-01 Claims 1-14 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. With respect to claims 1, and 13, it is not clear of what is meant by “calculate colorability and variation in frequency spectrum intensity concerning the environmental sound; and determine whether or not the environmental sound includes the operating sound by comparing the colorability and a degree of the variation with thresholds.” With respect to claim 14, it is not clear of what is meant by “calculate colorability and variation in frequency spectrum intensity concerning the environmental sound; and compare the colorability and a degree of the variation with thresholds and determine whether the environmental sound includes the operating sound.” It is unclear to examiner how acquiring of sound, then calculating colorability and frequency specturum, comparing them is leading to detecting anomaly among the elevator ?
