Office Action

§102 §DP
DETAILED ACTION The action is responsive to the following communications: the Application filed June 26, 2024 and the information disclosure statement (IDS) filed July 02, 2024. This application is a CON of 17/546,425 filed December 09, 2021. Claims 1-20 are pending. Claims 1, 8 and 15 are independent. Notice of Pre-AIA or AIA Status The present application is being examined under the first inventor to file provisions of the AIA . Information Disclosure Statement The information disclosure statement (IDS) submitted on July 02, 2024 is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. 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 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); 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 nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP §§ 706.02(l)(1) - 706.02(l)(3) for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/process/file/efs/guidance/eTD-info-I.jsp. Independent claims 1-20 are rejected on the ground of nonstatutory double patenting as being unpatentable over independent claims 1-20 of US Patent No. 12,062,394. Although the claims at issue are not identical, they are not patentably distinct from each other. Instant Application US Patent 12,062,394 Comment Claim 1. A system comprising: a memory device; and a processing device, operatively coupled to the memory device, to perform operations comprising: performing a write operation to program first data to a first set of memory cells addressable by a first wordline of a first plurality of wordlines of a block of the memory device; performing a read operation on a second wordline of the plurality of wordlines, wherein the second wordline is adjacent to the first wordline; determining a number of bits programmed in a first logical level in the second wordline; and responsive to determining that the number of bits programmed in the first logical level fails to satisfy a threshold criterion, performing a write operation on the second wordline to program second data. Claim 1. A system comprising: a memory device; and a processing device, operatively coupled to the memory device, to perform operations comprising: performing a write operation to program first data to a first set of memory cells addressable by a first wordline of a first plurality of wordlines of a first block of the memory device; performing a read operation on a second wordline of the plurality of wordlines, wherein the second wordline is a sequentially next and unwritten to wordline in the first block and is adjacent to the first wordline; determining a number of bits programmed in a first logical level in the second wordline; and responsive to determining that the number of bits programmed in the first logical level satisfies a threshold criterion, copying second data from the first block to a second block. Note footnote1 Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of AIA 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)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale or otherwise available to the public before the effective filing date of the claimed invention. Claims 1-20 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Koh et al. (US 2013/0229868). Regarding independent claims 1, 8 and 15, Koh et al. disclose a system comprising: a memory device (see FIG. 1); and a processing device, operatively coupled to the memory device, to perform operations comprising: performing a write operation (e.g., Abstract: the data from a previously written) to program first data to a first set of memory cells addressable by a first wordline of a first plurality of wordlines of a block of the memory device; performing a read operation (… adjacent is word line is read back) on a second wordline of the plurality of wordlines, wherein the second wordline is adjacent to the first wordline; determining (… If a short occurs, …) a number of bits programmed in a first logical level in the second wordline (… both word lines); and responsive to determining that the number of bits programmed in the first logical level fails to satisfy a threshold criterion (… If a short occurs, …), performing a write operation on the second wordline to program second data (… it (i.e., both word lines) can be written to a new location; also see para. 0162). Further, reprogramming a defected (claimed fail to satisfy a threshold criterion) word line due to interference with adjacent word lines is a well-known technology in a memory device. For support, see for example, Hsu et al. (US 2017/0322843), para. [0004]: For example, if the failure is due to a short between word lines … both the word line being programmed …; and Kleveland et al. (US 7,212,454), Abstract: The word lines are then reprogrammed and … a defect on that word line and a previously-programmed adjacent word line. If a defect is detected on that word line, that word line and the previously-programmed adjacent word line are repaired … Regarding claims 2, 9 and 16, Koh et al. disclose retiring the block from further use by the memory device (see e.g., para. 0096: … then remove it from … usable blocks). Regarding claims 3, 10 and 17, Koh et al. disclose performing another write operation to program the first data to a third block (para. 0162: the other block, which implies a third block in multi-block structure). Regarding claims 4, 11 and 18, Koh et al. disclose the first set of memory cells comprises each memory cell associated with the first wordline (see FIGS. 1 and 4, and accompanying disclosure). Regarding claims 5, 12 and 19, Koh et al. disclose the first set of memory cells comprises a predetermined subset of memory cells associated with the first wordline (e.g., para. 0069: … the subset of cells … the entire row …). Regarding claims 6, 13 and 20, Koh et al. disclose the processing device to perform further operations comprising: the threshold criterion comprises a threshold value of set bits (see e.g., para. 0062-0063). Regarding claims 7 and 14, Koh et al. disclose determining a count of memory cells programmed in a second logical level in the second wordline (see e.g., para. 0116: … using the total program loop count to judge this failure could result in false alarms). Documents Considered but not Relied Upon The documents below were considered. Hsu et al. (US 2017/0322843), Kleveland et al. (US 7,212,454), Karr et al. (US 2020/0082890), and Shappir et al.
