Office Action

§102
CTNF 18/668,454 CTNF 75190 Notice of Pre-AIA or AIA Status 07-03-aia AIA 15-10-aia The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA. This is in response to Application filed 05/20/24. Claims 1 – 10 have been examined and are pending. Claim Rejections - 35 USC § 102 07-07-aia AIA 07-07 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 – 07-12-aia AIA (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. 07-15-03-aia AIA Claim(s) 1 – 10 is/are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Ebcioglu et al. US 896,6457 . Regarding claims 1 7, and 9, Ebcioglu anticipates a code conversion device comprising: a memory storing instructions; and one or more processors configured to execute the instructions to: accept input of a target program code which is the program code to be processed; extract, from the target program code (135:55 – 60, see target and extract), a first program code indicating that aggregation processing of each column in a data frame is performed based on a predetermined column value for a data frame representing data in a two-dimensional tabular format, and a second program code indicating predefined processing to be performed on each data frame for which the aggregation processing is performed and a function that calls the predefined processing (25:63 – 26:15, shows converting to single threaded code regarding aggregation and see combining instructions ); convert the extracted first program code and second program code into alternative program code, which is program code indicating a process that does not make a function call that invokes the predefined processing by the function and that produces a same result as the processing by the first program code and the second program code; and output the alternative program code (25:63 – 26:15, shows converting to single threaded code regarding aggregation and see combining instructions and invocation). Regarding claims 2, 8 and 10, the code conversion device according to claim 1, wherein the processor is configured to execute the instructions to generate the alternative program code by converting a program code contained in the function indicated by the second program code into a corresponding predetermined program code (10:14 – 40, see parallel code for generating alternative program code). Regarding claim 3, the code conversion device according to claim 1, wherein the processor is configured to execute the instructions to convert the first program code and the second program code into the alternative program code when a type of arguments used to call a processing and a type of a return value of the processing match (143:8 – 30, see convert and match). Regarding claim 4, the code conversion device according to claim 1, wherein the processor is configured to execute the instructions to convert a code indicated by a first operation, which is expressed by an expression linked by an equal sign among operations in predefined processing, into a code for speed-up the processing when both right and left sides of the expression are operations on the data frame to be the argument when invoking the processing, and when there is no possibility of changing the number of lines of the data frame to be the argument by the first operation (36:20 – 30, see operands). Regarding claim 5, the code conversion device according to claim 1, wherein the processor is configured to execute the instructions to convert a code indicated by a first operation, which is expressed by an expression linked by an equal sign among operations in predefined processing, into a code for speed-up the processing when at least one of right and left sides of the expression is not an operation on the data frame to be the argument when invoking the processing(36:20 – 30, see operands). Regarding claim 6, the code conversion device according to claim 5, wherein the processor is configured to execute the instructions to convert a code indicated by the operation expressed by the expression linked by an equal sign into a code for speed-up the processing when a data frame other than the data frame is generated by an equal sign filter by a key to be aggregated in the data frame to be the argument (25:63 – 26:15, shows converting to single threaded code regarding aggregation and see combining instructions ).
