Office Action

§103 §112 §DP
DETAILED ACTION 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 . Information Disclosure Statement Acknowledgment is made of applicant's Information Disclosure Statement (IDS) Form PTO-1449, filed. The information disclosed therein was considered. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 2-11, 13-18 and 20 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claims 2, 13 and 20 recite “being in one of a plurality of groups”. Parent claims previously establish “computing a group” and it is unclear if these terms are tied together and therefore the antecedent basis is unclear. For examination purposes (see below), it is interpreted as referring to the same group which is computed in the parent claim(s). 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 § 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 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. Claims 1-20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-20 of U.S. Patent No. 11,335,407. Although the claims at issue are not identical, they are not patentably distinct from each other because the claims of the ‘407 patent clearly anticipate the claims of the instant application. Claims 1-20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-20 of U.S. Patent No. 11,990,186. Although the claims at issue are not identical, they are not patentably distinct from each other because the claims of the ‘186 patent clearly anticipate the claims of the instant application. 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. Claim(s) 1, 12 and 19 is/are rejected under 35 U.S.C. 103 as being unpatentable over Conley in view of Yoo (US 8,331,144). Regarding claims 1, 12 and 19, Conley discloses a device, comprising: memory cells (see Figure 3); and a logic circuit coupled with the memory cells (see Figure 5) and configured to: receive a plurality of pages of data bits (see Figure 20); and program a page of the memory cells to have threshold voltages representative of the plurality of pages of data bits, via: programming, in a first pass, a threshold voltage of each respective memory cell in the page of the memory cells (see paragraph 0122) and increasing a voltage applied to the page of the memory cells to a sequence of read voltages in an increasing order (see Figure 11). Conley fails to teach the step of computing a group identification for the respective memory cell. However, one of ordinary skill was aware at the time of many reasons for determining a group identification of memory cells. For example, Yoo teaches computing a group identification for cells as aggressor cells or victim cells (see Figure 3 for example). Therefore, it would have been obvious to one having ordinary skill at the time of filing to compute a group identification for the respective memory cells being programmed in order to reduce disturbance in a program operation. Allowable Subject Matter Claims 2-11, 13-18 and 20 are provisionally objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims and an overcoming of the double patenting rejection by Terminal Disclaimer and the overcoming of the antecedent issues in the manner interpreted by the Examiner above. The following is a statement of reasons for the indication of allowable subject matter: while the prior art teaches various embodiments of grouping and program passes, the prior art fails to teach or reasonably suggest in combination each of the threshold levels being in one of a plurality of groups, each of the plurality of groups containing a subset of the threshold levels and having a set of associated read voltages that separate threshold levels in the subset.
