Office Action

§DP
CTNF 18/952,668 CTNF 79572 DETAILED ACTION Application filed 11/19/2024 has been examined. 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. Claims 1-20 are pending. Specification and drawings are accepted. IDS has been considered. PTO-1449 is attached. Application is pending. Double Patenting 08-33 AIA 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 § 2146 et seq. 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 filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13. The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual 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/apply/applying-online/eterminal-disclaimer. Claims 1-20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-19 of U.S. Patent No. 12,164,373. Although the claims at issue are not identical, they are not patentably distinct from each other. For example, claim 1 of the present application teaches a memory chip, comprising: a storage array having a plurality of rows individually configured to include storage cells to store a count value of a respective row’s activations and to store error correction code (ECC) information; and circuitry configured to: correct a detected error in a count value of a row from among the plurality of rows; increment the count value if the count value is below a threshold; determine new ECC information for the incremented count value; and write the incremented count value and the new ECC information into the row’s storage cells. Whereas claim 1 of U.S. patent ‘373 teaches a memory chip, comprising: a) storage cells along a row of the memory chip's storage cell array to store a count value of the row's activations and error correction code (ECC) information to protect the count value; b) ECC read logic circuitry to correct an error in the count value; c) a comparator to compare the count value against a threshold; d) circuitry to increment the count value if the count value is deemed not to have reached the threshold and ECC write logic circuitry to determine new ECC information for the incremented count value, and write driver circuitry to write the incremented count value and the new ECC information into the storage cells; and ,e) circuitry to cause the row to be refreshed if the count value is deemed to have reached the threshold. Both sets of claims are directed towards a memory chip with the capability of storing a count value of the row’s activations and error correction information to protect the count value wherein the ECC detects an error in the count value and increments the count value if below threshold, determines new ECC information for the incremented count value and then writes the incremented count value to the row’s storage cells. Therefore the claims are obvious variations and obvious embodiments of each other and not patentably distinct. A terminal disclaimer would obviate the rejection. Conclusion 07-96 AIA The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. See PTO-892 .
