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 1, 2, 9, 10, 15, and 16 are objected to because of the following informalities:
Regarding claim 1, in line 6, replace “the real part and the imaginary part” with --a real part and an imaginary part--. In lines 16-17, replace “for the first part” with --for the first part cross-correlation--. In line 21, replace “for the second part” with --for the second part cross-correlation--.
Regarding claim 2, in lines 2-3, replace “the frame in the first frequency-domain signal” with --a frame in the first frequency-domain signal--. In lines 3-4, replace “the frame in the second frequency-domain signal” with --a frame in the second frequency-domain signal--.
Regarding claim 9, in line 3, replace “the greatest received signal power” with --a greatest received signal power--.
Regarding claim 10, in lines 3-4, replace “the most concentrated autocorrelation or the flattest spectrum” with --a most concentrated autocorrelation or a flattest spectrum--.
Regarding claim 15, in line 6, replace “the real part and the imaginary part” with --a real part and an imaginary part--. In line 19, replace “for the first part” with --for the first part cross-correlation--. In line 23, replace “for the second part” with --for the second part cross-correlation--.
Regarding claim 16, in lines 3-5, replace “the cross-correlation for the second part for frames where the frame in the first frequency-domain signal is one frame ahead of the frame in the second frequency-domain signal” with --the cross-correlation where a frame in the first frequency-domain signal is one frame ahead of a frame in the second frequency-domain signal--.
Appropriate correction is required.
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 1-20 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 independent claim 1, the limitation “a Fourier-related transform” recited in line 4 renders claim indefinite. A Fourier transform can be in a form of Discrete Fourier Transform, Short-time Fourier Transform, Generalized Discrete Fourier Transform, Modified Discrete Cosine Transform, Modified Discrete Sine Transform, Fast Fourier Transform, etc… Therefore, a Fourier-related transform fails to meet the “metes and bounds” of the claim.
Regarding independent claim 15, the limitation “a Fourier-related transform” recited in line 4 renders claim indefinite. A Fourier transform can be in a form of Discrete Fourier Transform, Short-time Fourier Transform, Generalized Discrete Fourier Transform, Modified Discrete Cosine Transform, Modified Discrete Sine Transform, Fast Fourier Transform, etc… Therefore, a Fourier-related transform fails to meet the “metes and bounds” of the claim.
Other claims are automatically rejected to for the reasons as set forth in rejected independent claims 1 and 15.
Allowable Subject Matter
Claims 1-15 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action.
The prior art does not teach or fairly suggest that wherein only one part, of a real part and an imaginary part from the Fourier transform, is included in the frequency-domain signals, wherein a first part is the part, real or imaginary, that is included in the frequency-domain signals and a second part is the part, real or imaginary, that is not included in the frequency-domain signals, determining a first part cross-correlation between the first frequency-domain signal and the second frequency-domain signal by cross-correlating corresponding frames in the first frequency-domain signal and the second frequency-domain signa, for the first part cross-correlation; and determining a second part cross-correlation between the first frequency- domain signal and the second frequency-domain signal by cross-correlating non-corresponding frames in the first frequency-domain signal and the second frequency-domain signal, for the second part cross-correlation, as specified in independent claims 1 and 15.
