Office Action

§102
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 . Allowable Subject Matter Claims 1-6, 8, and 10-11 are allowed. The prior art fails to disclose determining a reference picture index i1 of a first reference picture list as a first reference picture index that corresponds to a current block and that is of the first reference picture list when mvd_l1_zero_flag equals to 0… and if one or both of the first reference picture index or the second reference picture index are not identified: searching the second reference picture list to identify the first reference picture index and searching the first reference picture list to identify the second reference picture index. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. 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 (i.e., changing from AIA to pre-AIA ) 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. Claim 7 and 9 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by U.S. Patent Publication No. 2013/0016789 (“Lou”). With respect to claim 7, patentable weight is given to data stored on a non-transitory computer-readable medium when there exists a functional relationship between the data and its associated substrate. MPEP 2111.05 III. For example, if a claim is drawn to a computer-readable medium containing programming, a functional relationship exists if the programming “performs some function with respect to the computer with which it is associated.” Id. However, if the claim recites that the computer-readable medium merely serves as a support for information or data, no functional relationship exists and the information or data is not given patentable weight. Id. Claim 7 is directed to a non-transitory storage medium storing a bitstream and steps describing how the bitstream is generated. These elements or steps are not performed by an intended computer, and the bitstream is not a form of programming that causes functions to be performed by an intended computer. This shows that the computer-readable medium merely serves as support for the bitstream and provides no functional relationship between the steps/elements that describe the generation of the bitstream and intended computer system. Therefore, those claim elements are not given patentable weight. Thus the claim scope is just a storage medium storing data and is anticipated by Lou which recites a storage medium storing a bitstream (see ¶155). Similarly, Claim 9 is directed to a non-transitory storage medium storing a bitstream and instructions and operations/steps describing how the bitstream is generated. These elements or steps are not performed by an intended computer, and the bitstream is not a form of programming that causes functions to be performed by an intended computer. This shows that the computer-readable medium merely serves as support for the bitstream and provides no functional relationship between the steps/elements that describe the generation of the bitstream and intended computer system. Therefore, those claim elements are not given patentable weight. Thus the claim scope is just a storage medium storing data and is anticipated by Lou which recites a storage medium storing a bitstream (see ¶155).
