Office Action

§DOUBLEPATENT §DP
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 . Response to Amendment 1. This office action is responsive to communication(s) filed on 4/3/2026. 2. Newly added claims 2-21 are presented for examination. Double Patenting 3. 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. See 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) may be used to overcome an actual or provisional rejection based on a nonstatutory double patenting ground provided the conflicting application or patent is shown to be commonly owned with this application. See 37 CFR 1.130(b). 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). 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. 4. Claims 2-21 are rejected under the judicially created doctrine of obviousness-type double patenting as being unpatentable over claims 1, 7-8 and 14 of U.S. Patent No. 10998080. Although the conflicting claims are not identical, they are not patentably distinct from each other because the examined application claim is either anticipated by, or would have been obvious over, the reference claims as follows: Claims 2, 5 and 9 of the examined application are anticipated and the same scope of invention by claim 14 of the reference such as a memory system, comprising: one or more memory devices; and one or more controllers coupled with the one or more memory devices and configured to cause the memory system to: determine to perform an imprint recovery procedure on a memory cell configured to store one of a set of logic states, wherein the imprint recovery procedure increases an ability of the memory cell to switch between storing a first logic state of the set of logic states and storing a second logic state of the set of logic states; and apply to the memory cell, based at least in part on determining to perform the imprint recovery procedure, a set of one or more access operations to increase the ability of the memory cell to switch between storing the first logic state of the set of logic states and storing the second logic state of the set of logic states. The claims 3-4, 11-12 and 19-20 of examined application are obvious over the claims of reference 14 because the claim seems to differ because the claim seems to differ from the reference in that the claimed invention of the examined application recites modify one or more parameters of the set of one or more access operations while in the reference is silent. However, a claim 22 of the U.S. Patent No. 11217303 disclose this limitation. Claims 6-8 are obvious to claims 6-8 of the reference. Claims 10 and 13-17 of the examined application are anticipated and the same scope of invention by claim 1 and6-8 of the reference such as an method, comprising: determining to perform an imprint recovery procedure on a memory cell configured to store one of a set of logic states, wherein the imprint recovery procedure increases an ability of the memory cell to switch between storing a first logic state of the set of logic states and storing a second logic state of the set of logic states; and applying to the memory cell, based at least in part on determining to perform the imprint recovery procedure, a set of one or more access operations to increase the ability of the memory cell to switch between storing the first logic state of the set of logic states and storing the second logic state of the set of logic states. The claims 18 and 21 of examined application are obvious over the claims of reference 14 because the claim seems to differ because the claim seems to differ from the reference in that the claimed invention of the examined application recites comprising instructions which, when executed by one or more processors of an electronic device while in the reference is silent. However, a claim 17 of the U.S. Patent No. 11557371 or a claim 19 the U.S. Patent No. 12040038 disclose this limitation. 5. Claims 2-21 are rejected under the judicially created doctrine of obviousness-type double patenting as being unpatentable over claims 1, 8-9, 18, 22 and 25 of U.S. Patent No. 11217303. Although the conflicting claims are not identical, they are not patentably distinct from each other because the examined application claim is either anticipated by, or would have been obvious over, the reference claims as follows: Claims 2-16 of the examined application are apparatus claims but they encompass the same scope of invention as to that of method claims 1, 8-9, 14, 18, 22 and 25 of the reference. Claims 2-5, 9-13, and 17 of the examined application are anticipated and the same scope of invention by a claim 22 of the reference such as a memory system, comprising: one or more memory devices; and one or more controllers coupled with the one or more memory devices and configured to cause the memory system to: determine to perform an imprint recovery procedure on a memory cell configured to store one of a set of logic states, wherein the imprint recovery procedure increases an ability of the memory cell to switch between storing a first logic state of the set of logic states and storing a second logic state of the set of logic states; and apply to the memory cell, based at least in part on determining to perform the imprint recovery procedure, a set of one or more access operations to increase the ability of the memory cell to switch between storing the first logic state of the set of logic states and storing the second logic state of the set of logic states. Claims 6-8 and 14-16 are obvious to claims 14, 18 and 25 of the reference. The claims 18 and 21 of examined application are obvious over the claims of reference 14 because the claim seems to differ because the claim seems to differ from the reference in that the claimed invention of the examined application recites comprising instructions which, when executed by one or more processors of an electronic device while in the reference is silent. However, a claim 17 of the U.S. Patent No. 11557371 or a claim 19 the U.S. Patent No. 12040038 disclose this limitation. Claims 19-20 are obvious to a claim 22 of the reference. 6. Claims 2-21 are rejected under the judicially created doctrine of obviousness-type double patenting as being unpatentable over claims 1-6 and 13-17 of U.S. Patent No. 11557371. Although the conflicting claims are not identical, they are not patentably distinct from each other because the examined application claim is either anticipated by, or would have been obvious over, the reference claims as follows: Claims 2 and 5-9 of the examined application are anticipated and the same scope of invention by claims 13-16 of the reference such as a memory system, comprising: one or more memory devices; and one or more controllers coupled with the one or more memory devices and configured to cause the memory system to: determine to perform an imprint recovery procedure on a memory cell configured to store one of a set of logic states, wherein the imprint recovery procedure increases an ability of the memory cell to switch between storing a first logic state of the set of logic states and storing a second logic state of the set of logic states; and apply to the memory cell, based at least in part on determining to perform the imprint recovery procedure, a set of one or more access operations to increase the ability of the memory cell to switch between storing the first logic state of the set of logic states and storing the second logic state of the set of logic states. The claims 3-4, 11-12 and 19-20 of examined application are obvious over the claims of reference 14 because the claim seems to differ because the claim seems to differ from the reference in that the claimed invention of the examined application recites modify one or more parameters of the set of one or more access operations while in the reference is silent. However, a claim 22 of the U.S. Patent No. 11217303 disclose this limitation. claims as follows: Claims 10 and 13-17 of the examined application are anticipated and the same scope of invention by claims 1 and 3-8 of the reference such as a method, comprising: determining to perform an imprint recovery procedure on a memory cell configured to store one of a set of logic states, wherein the imprint recovery procedure increases an ability of the memory cell to switch between storing a first logic state of the set of logic states and storing a second logic state of the set of logic states; and applying to the memory cell, based at least in part on determining to perform the imprint recovery procedure, a set of one or more access operations to increase the ability of the memory cell to switch between storing the first logic state of the set of logic states and storing the second logic state of the set of logic states. Claims 18 and 21 of the examined application are anticipated and the same scope of invention by a claim 17 of the reference such as a non-transitory computer-readable medium storing code comprising instructions which, when executed by one or more processors of an electronic device, cause the electronic device to: determine to perform an imprint recovery procedure on a memory cell configured to store one of a set of logic states, wherein the imprint recovery procedure is to increase an ability of the memory cell to switch between storing a first logic state of the set of logic states and storing a second logic state of the set of logic states; and apply to the memory cell, based at least in part on determining to perform the imprint recovery procedure, a set of one or more access operations to increase the ability of the memory cell to switch between storing the first logic state of the set of logic states and storing the second logic state of the set of logic states. 7. Claims 2-21 are rejected under the judicially created doctrine of obviousness-type double patenting as being unpatentable over claims 1-6 and 13, 17-19 of U.S. Patent No. 12040038. Although the conflicting claims are not identical, they are not patentably distinct from each other because the examined application claim is either anticipated by, or would have been obvious over, the reference claims as follows: Claims 2 and 5-9 of the examined application are anticipated and the same scope of invention by claims 13 and 17-18 of the reference such as a memory system, comprising: one or more memory devices; and one or more controllers coupled with the one or more memory devices and configured to cause the memory system to: determine to perform an imprint recovery procedure on a memory cell configured to store one of a set of logic states, wherein the imprint recovery procedure increases an ability of the memory cell to switch between storing a first logic state of the set of logic states and storing a second logic state of the set of logic states; and apply to the memory cell, based at least in part on determining to perform the imprint recovery procedure, a set of one or more access operations to increase the ability of the memory cell to switch between storing the first logic state of the set of logic states and storing the second logic state of the set of logic states. The claims 3-4, 11-12 and 19-20 of examined application are obvious over the claims of reference 14 because the claim seems to differ because the claim seems to differ from the reference in that the claimed invention of the examined application recites modify one or more parameters of the set of one or more access operations while in the reference is silent. However, a claim 22 of the U.S. Patent No. 11217303 disclose this limitation. claims as follows: Claims 10 and 13-17 of the examined application are anticipated and the same scope of invention by claims 1 and 5-7 of the reference such as a method, comprising: determining to perform an imprint recovery procedure on a memory cell configured to store one of a set of logic states, wherein the imprint recovery procedure increases an ability of the memory cell to switch between storing a first logic state of the set of logic states and storing a second logic state of the set of logic states; and applying to the memory cell, based at least in part on determining to perform the imprint recovery procedure, a set of one or more access operations to increase the ability of the memory cell to switch between storing the first logic state of the set of logic states and storing the second logic state of the set of logic states.
