Double Patenting
The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969).
A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b).

Allowable Subject Matter
Claims 1-20 are allowed over the prior art of record.
The following is an examiner’s statement of reasons for allowance:
With respect to the independent claims, the prior art of record fail to disclose generating a first excitation signal based on a first non-linear processing function, generating a second excitation signal based on a second non- linear processing function, and generating a high-band excitation signal based on the first excitation signal and the second excitation signal. Vos (20070088558) generates lowband and highband signals based on information from the wideband signal – para 0009, with the associated sampling – para 0119-0120; and fig 2a, 2b). Vos (20070088558) further describes that a nonlinear function calculator 520 is configured to apply a nonlinear function to an upsampled signal. Vos describes that a potential advantage of the absolute value function over other nonlinear functions for spectral extension, such as squaring, is that energy normalization is not needed. See Vos, para. [0120]. Each of Plot (c) of FIG. 12a and Plot (c) of FIG. 12b shows an example of the extended spectrum after application of a nonlinear function. See Vos, para. [0122] and FIGS. 12a and 12b. Vos thus describes applying a single nonlinear function (e.g., absolute value function OR squaring) to generate a highband excitation signal. The cited portions of Vos do not disclose generating the high-band excitation signal based on a plurality of non-linear processing functions. McCree, Alan V. (20020007280) teaches, para[0060], coders and decoders follow the first preferred embodiment coders and decoders and partition the sampled input into a lowband and a highband, downsample, and apply a narrowband coder to the lowband. However, the second preferred embodiments vary the encoding of the highband with modulated noise-excited LP by deriving the modulation from the envelope of lbdh(m) rather than its absolute value. In particular, find the envelope en(m) of lbdh(m) by lowpass (0-1 kHz) filtering the absolute value .vertline.lbdh(m).vertline. plus notch filtering to remove dc. FIG. 7 illustrates en(m) for the voiced speech of FIG. 6 in the time domain.
Rajendran et al. 20080027717, para [0091], teaches a description of a spectral envelope of a frame also includes a description of temporal information of the frame (e.g., as in an ordered sequence of Fourier transform coefficients). In other cases, the set of speech parameters of an encoded frame may also include a description of temporal information of the frame. The form of the description of temporal information may depend on the particular coding mode used to encode the frame. For some coding modes (e.g., for a CELP coding mode), the description of temporal information may include a description of an excitation signal to be used by a speech decoder to excite an LPC model (e.g., as defined by the description of the spectral envelope). A description of an excitation signal typically appears in an encoded frame in quantized form (e.g., as one or more indices into corresponding codebooks). The description of temporal information may also include information relating to a pitch component of the excitation signal. For a PPP coding mode, for example, the encoded temporal information may include a description of a prototype to be used by a speech decoder to reproduce a pitch component of the excitation signal. A description of information relating to a pitch component typically appears in an encoded frame in quantized form (e.g., as one or more indices into corresponding codebooks).
Gupta et al 20090319262, para [0195], teaches apparatus MF200 also includes means FD200 for decoding a portion of a second encoded frame to obtain a second excitation signal, where the portion includes representations of a pitch pulse shape differential and a pitch period differential. Means FD200 includes means FD210 for calculating a second pitch pulse shape based on the time-domain pitch pulse shape and the pitch pulse shape differential. Means FD200 also includes means FD220 for calculating a second pitch period based on the pitch period and the pitch period differential. Means FD200 also includes means FD230 for arranging two or more copies of the second pitch pulse shape within the second excitation signal according to the pitch pulse position and the second pitch period. Means FD230 may be configured to calculate a position for each of the copies within the second excitation signal as a corresponding offset from the pitch pulse position, where each offset is an integer multiple of the second pitch period. Means FD200 and/or apparatus MF200 may also be implemented to include means for obtaining a set of LPC coefficient values from the second encoded frame (e.g., by dequantizing one or more quantized LSP vectors from the second encoded frame and inverse transforming the result), means for configuring a synthesis filter according to the set of LPC coefficient values, and means for applying the second excitation signal to the configured synthesis filter to obtain a second decoded frame.
However, none of the prior art of record explicitly teaches the claimed generating a high-band excitation signal based on a first and second high band frequency subrange generated on two different non-linear processing functions.
