Office Action

§101 §103 §DP
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 . Specification The abstract of the disclosure is objected to because the language, “[r]elated devices and computer program products are disclosed,” in the abstract recites legal phraseology and is making the reader go into the Specification. Correction is required. See MPEP § 608.01(b). Applicant is reminded of the proper language and format for an abstract of the disclosure. The abstract should be in narrative form and generally limited to a single paragraph on a separate sheet within the range of 50 to 150 words in length. The abstract should describe the disclosure sufficiently to assist readers in deciding whether there is a need for consulting the full patent text for details. The language should be clear and concise and should not repeat information given in the title. It should avoid using phrases which can be implied, such as, “The disclosure concerns,” “The disclosure defined by this invention,” “The disclosure describes,” etc. In addition, the form and legal phraseology often used in patent claims, such as “means” and “said,” should be avoided. Claim Rejections - 35 USC § 101 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. Claim 134 is rejected under 35 U.S.C. 101 because the claimed invention is directed to non-statutory subject matter. Regarding claim 134, the claim is drawn to a, “computer program product.” Computer programs or software per se do not fit within recognized categories of statutory subject matter. See In re Nuijten, 500 F.3d 1346, 1356-57 (Fed. Cir. 2007) (transitory embodiments are not directed to statutory subject matter) and Interim Examination Instructions for Evaluating Subject Matter Eligibility Under 35 U.S.C. § 101, Aug. 24, 2009; p. 2. A claim directed to a computer program itself or signal or carrier wave and/or non-transitory media is non-statutory because it is not: A process occurring as a result of executing the program, or A machine programmed to operate in accordance with the program, A manufacture structurally and functionally interconnected with the program in a manner which enable the program to act as a computer component and realize its functionality, or A composition of matter. The applicant is advised to amend claims so that the claim(s) are directed to a form of non-transitory tangible media. Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102 of this title, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claims 1, 134 & 136 are rejected under 35 U.S.C. 103 as being unpatentable over Bruls et al. (US 6,614,989 B1) (hereinafter Bruls) in view of Sita (US 2004/0150747 A1) (hereinafter Sita). Regarding claim 1, Bruls discloses a computer-implemented method of encoding a colour video, the colour video comprising colour video frames, the colour video frames including 1920 pixels by 1080 pixels [Cols. 2-4, ll. 66-25, HDTV encoder implementing encoding of HDTV video frames being 1920x1080 luminance pixels], the method including the step of: (i) encoding colour video frames using a 240 elements by 135 elements representation of the 1920 pixels by 1080 pixels, each element comprising an encoded 8x8 pixel block, wherein each encoded 8x8 pixel block is represented using a representation including a codeword [Cols. 2-4, ll. 66-25, encoding of HDTV video frames being 1920x1080 luminance pixels, with 240x135 blocks as shown in Fig. 1, dividing into image blocks of 8x8 pixels, transformed into 64 spectral coefficients represented by 12 bits as codewords]. However, Bruls does not explicitly disclose the codeword including 64 bits, wherein the codeword comprises 64 bits including a codeword type, with zero or more extension codewords depending on the codeword type specified. Sita teaches the codeword including 64 bits, wherein the codeword comprises 64 bits including a codeword type, with zero or more extension codewords depending on the codeword type specified [Paragraph [0207], The coefficients for the exemplary embodiment are placed in a 64 bit word from left to right, C0 to C7. The coefficients C0, C1, C6 and C7 are signed 7-bit 2's complement values, and C2 and C5 are signed 8-bit 2's complement and C3 and C4 are signed 10-bit 2's complement values representing a range from -256 to 767. C3 and C4 are adjusted to derive the 11-bit 2's complement values. If both bit 8 and bit 9 (the most significant bit) are 1, then the sign of the 11-bit value is 1 (negative), otherwise the value is 0 (positive)]. It would have been obvious to the person of ordinary skill in the art before the effective filing date of the claimed invention to modify the method disclosed by Bruls to integrate the 64-bit codeword data in Sita as above, to provide decoding systems that are relatively inexpensive and yet have sufficient power to decode digital signals in real time and supports conversion into multiple low resolution formats that must minimize processor memory (Sita, Paragraph [0008]). Regarding claim 134, claim 134 is drawn to a computer program product that recites limitations similar to the same method as claimed in claim 1, and therefore is also rejected for the same reasons of obviousness as listed above. Regarding claim 136, device claim 136 is drawn to the device using/performing the same method as claimed in claim 1. Therefore device claim 12 corresponds to method claim 1, and is rejected for the same reasons of obviousness as used above. Allowable Subject Matter Claims 2-5, 8-10, 13-27 & 137 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims, and overcoming the nonstatutory double patenting rejections outlined above. Claims 2-5, 8-10, 13-27 & 137 contain allowable subject matter. The following is a statement of reasons for the indication of allowable subject matter: The various claimed limitations mentioned in the claims are not taught or suggested by the prior art taken either singly or in combination, with emphasize that it is each claim, taken as a whole, including the interrelationships and interconnections between various claimed elements make them allowable over the prior art of record.
