DETAILED ACTION
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
In the event the determination of the status of the application as subject to AIA 35U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, anycorrection of the statutory basis for the rejection will not be considered a new ground ofrejection if the prior art relied upon, and the rationale supporting the rejection, would bethe same under either status.
Double Patenting
The non-statutory 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 non-statutory obviousness-type 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 Orne, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); and In re Torrington, 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 a non-statutory double patenting ground provided the conflicting application or patent either is shown to be commonly owned with this application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement.
Effective January 1, 1994, a registered attorney or agent of record may sign a terminal disclaimer. A terminal disclaimer signed by the assignee must fully comply with 37 CFR 3.73(b).
Claims 1-3 are rejected on the ground of non-statutory obviousness-type double patenting as being unpatentable over claims 1-3 of issued application of Seo et al., U.S. Patent No. 12,137,248 B2 (Seo’248 hereinafter). Although the conflicting claims are not identical, they are not patentably distinct from each other because the subject matter claimed in the instant application is covered by the issued patent Seo’248.
Regarding claims 1-3 the difference between the conflicting claims of the instant application and issued patent, Seo’248, are set forth in the discussion below.

Regarding claim 1, Sakai (US 2006/0067403 A1) teaches generating a prediction block based on the intra prediction mode, and generating a reconstructed block using the prediction block and the residue signal block (Figs. 1 and 6A-6C, [0018-0019, 0021], a bit stream is input to a CABAC decoder 110. The CABAC decoder 110 outputs a value obtained by performing discrete cosine transform and quantization of a residual error signal in unit of macro block, and a mode whether intra prediction or inter prediction. Further, the CABAC decoder 110 outputs values such as motion vectors in the case of inter prediction. From the intra prediction unit 120 or the inter prediction unit 125, either of the prediction signals is output to the adder 130 according to the prediction mode by means of a mode determining unit 127. The adder 130 adds the output value from the inverse discrete cosine transform unit 114 and the prediction signal from the mode determining unit 127, and outputs a local decode image. Decoder 100 that enables intra prediction. In order to enhance the resolution of decode images after decoding processing by the decoder, information of the intra prediction direction that the prediction mode of intra prediction shows (intra prediction mode), and differential (residual signal) information from original images at intra prediction are stored into a main memory (not shown)).
Regarding claim 2, Sakai (US 2006/0067403 A1) teaches determining an intra prediction mode (Fig. 1, [0018], a bit stream is input to a CABAC decoder 110. The CABAC decoder 110 outputs a value obtained by performing discrete cosine transform and quantization of a residual error signal in unit of macro block, and a mode whether intra prediction or inter prediction. Further, the CABAC decoder 110 outputs values such as motion vectors in the case of inter prediction. The dispersion cosine transformed and quantized value among the output signals from the CABAC decoder 110 is inverse quantized and reserve dispersion cosine transformed by an inverse quantization unit 112 and an inverse discrete cosine transform unit 114, respectively, and is input into an adder 130. On the other hand, an intra prediction mode is output from the CABAC decoder 110 to an intra prediction unit 120 according to prediction modes, and an inter prediction mode and a motion vector are output to an inter prediction unit 125).
Regarding claim 3, Sakai (US 2006/0067403 A1) teaches determining an intra prediction mode (Fig. 1, [0018], a bit stream is input to a CABAC decoder 110. The CABAC decoder 110 outputs a value obtained by performing discrete cosine transform and quantization of a residual error signal in unit of macro block, and a mode whether intra prediction or inter prediction. Further, the CABAC decoder 110 outputs values such as motion vectors in the case of inter prediction. The dispersion cosine transformed and quantized value among the output signals from the CABAC decoder 110 is inverse quantized and reserve dispersion cosine transformed by an inverse quantization unit 112 and an inverse discrete cosine transform unit 114, respectively, and is input into an adder 130. On the other hand, an intra prediction mode is output from the CABAC decoder 110 to an intra prediction unit 120 according to prediction modes, and an inter prediction mode and a motion vector are output to an inter prediction unit 125).
It would have been obvious to one of the ordinary skill in the art before the effective filing date of the claimed invention to modify the system of Seo’248 by incorporating the features as taught by Sakai in order to provide a more effective and efficient system that is capable of generating a prediction block based on the intra prediction mode, and generating a reconstructed block using the prediction block and the residue signal block, and determining an intra prediction mode. The motivation is to support an improved method by quantifying intra prediction precision and adding it to parameters, a high-definition image can be generated (see [0009]).
