Office Action

§103
DETAILED ACTION 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. Response to Arguments Applicant’s arguments filled 07/24/2026 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Claim Rejections - 35 USC § 103 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, 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claims 1-7, 9-18, 20 and 23 are rejected under 35 U.S.C. 103 as being unpatentable over Abboud(US 5179712 A) in view of Halma(US 5907684 A) Regarding claim 1, Abboud discloses A method for ordered statistics constant false alarm rate (OS-CFAR) detection (“a number ranking circuit for an OS CFAR detector circuit “ [(Col.2, ll.46-47]), comprising: storing, at storage circuitry comprising a plurality of storage segments (“ranking circuitry is provided which includes a number of identically structured rank cells for storing and ranking sample values” [Col.2, ll.64-66]) address data (FIG.2, Parts RC1-RC8)[…]; and performing a sorting algorithm for OS-CFAR detection comprising the steps of: comparing a new data element of the radar data to at least one data element indicated by address data (“a new sample VIN is added to the rank array RC1 . . . RC8, the new sample VIN is compared to the sample VQ in each of the other rank cells RC1 . . . RC8” [Col.4, ll.58-61]) […], determining a storage segment of the plurality of storage segments at which address data of the new data element is to be stored based on the comparing (“The signals in the rank cells RC1 . . . RC8 are then shifted in a manner such that there exists a vacancy for the new sample VIN “ [Col.4, ll.61-64]), and controlling the storage circuitry to shift address data stored at the determined storage segment to another storage segment (“ all signals are once again ranked in descending order after the new sample VIN has been inserted into the vacant rank cell.” [Col.4, ll.64-66]). Abboud does not explicitly disclose nor limit wherein the address data indicates the addresses of data elements of radar data stored at a further storage circuitry. Halma discloses, address data indicating addresses of data elements of radar data stored at a further storage circuitry that is separate from the storage circuitry (“the indexed logical address comprises a pointer into the logical address table which contains the actual image identifier concatenated with the process node identifier at the channel end of the link in a channel path” [Col.6, ll.50-53]), wherein each portion of the address data has a smaller bit- width than the data element of the radar data indicated by that portion of the address data (“said indexed logical address having less bits than a concatenation of said Image.sub.-- ID and said PN.sub.-- ID.” [CLM. 25]) Halma teaches in the same field of data processing systems. It would have been obvious to one of ordinary skill in the art prior to the effective filing date of the claimed invention to modify Abboud with the teachings of Halma to incorporate the features of storing addresses of data elements of radar data at a further storage circuitry so as to gain the advantage of improving information retrieval efficiency. Also, since it has been held that if a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill (MPEP 2143).

RC8 may be cleared or reset by placing a sample value of zero in each rank cell RC1 . . . RC8. To build up the window size after such a reset, as shown in FIG. 4, video samples must be inserted into the window one at a time, while at the same time extracting zero amplitude samples.” [Cpl.4, ll.42-48]); and performing the sorting algorithm for the second window by removing a portion of the address data stored in the storage circuitry during performance of the sorting algorithm for the first window, wherein the portion of the address data is less than an entirety of the address data (“FIG. 5 illustrates a method of reducing the window size utilizing the rank cell array of the preferred embodiment. In this method, zero is inserted into the window, while, at the same time, one of the video samples is extracted from the window.” [Col.4, ll.48-52]) Regarding claim 6, Abboud as modified by Halma discloses all the limitations of claim 5.
