Office Action

§DP
DETAILED ACTION Summary This office action for US Patent application 18/817451 is responsive to communications filed on August 28th, 2024. Currently, claim 1 are pending are presented for examination. 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 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 Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); and 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 a nonstatutory 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). Claim 1 provisionally rejected on the ground of nonstatutory obviousness-type double patenting as being unpatentable over claim 24 of copending Application No 18/008992. Although the conflicting claims are not identical, they are not patentably distinct from each other because it is merely in the terminology used in both sets of claims. This is a provisional obviousness-type double patenting rejection because the conflicting claims have not in fact been patented. Below is a list of limitations that perform the same function. However different terminology is used in both sets to describe the limitations. Conflicting Co-pending Application 18/008992 Instant Application-18/817451-Note* bold means difference in the instant application 24. A method of decoding an input data signal representing successive data items, the method comprising: storing history data for decoded data items, the history data indicating one or more aspects of decoding the decoded data items; decoding a given data item by a first decoding technique, the first decoding technique comprising decoding a series of zero or more data sets, each data set representing a respective range of values of the data items and selecting the series of data sets from a plurality of candidate data sets in dependence upon (i) a number of previously decoded data sets; and (ii) the history data applicable to a given property of the given data item; and decoding, by circuitry, any remaining value of the given data item, the remaining value being an amount by which the given data item exceeds a maximum value which can be decoded by the first decoding technique, by a second decoding technique different to the first decoding technique. 1. A method of encoding successive data items, the method comprising: storing history data for encoded data items, the history data indicating one or more aspects of encoding the encoded data items; encoding a given data item by a first encoding technique, the first encoding technique comprising encoding a series of zero or more data sets, each data set representing a respective range of values of the data items and selecting the series of data sets from a plurality of candidate data sets in dependence upon (i) a number of previously encoded data sets; and (ii) the history data applicable to a given property of the given data item; and encoding any remaining value of the given data item, the remaining value being an amount by which the given data item exceeds a maximum value which can be encoded by the first encoding technique, by a second encoding technique different to the first encoding technique. Although the conflicting claims are not identical, they are not patentably distinct from each other because claim 1 is generic to all that is recited in claim 24 respectively of co-pending application. That is, claim 1 is/are anticipated by claim 24 respectively of co-pending application. Claim 1 is provisionally rejected on the ground of nonstatutory obviousness-type double patenting as being unpatentable over claim 24 respectively of copending Application. Allowable Subject Matter Claim 1 is/are rejected on the ground of nonstatutory obviousness-type double patenting. However, these claims would be allowable if the obvious-type double patenting is overcome.
