Office Action

§112 §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 . Non-Final Rejection This is to accept/enter the election without traverse, and replace the prior (non-final) communication, which had an SSP, and reset the reply period to 3 mos. from this rejection. 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 1-25 are rejected under 35 USC 112. The claim recites a “composition” but includes system- and method-like limitations, including “a polymerase to add nucleotides” and “detection circuitry to detect a sequence in which the polymerase adds the nucleotides,” such that it is unclear what structural relationship is required among the recited components in the claimed composition. Additionally, the phrases “using at least a sequence of the second polynucleotide,” “the labels corresponding to those nucleotides respectively altering an electrical characteristic,” and “using at least changes in an electrical signal through the bridge” fail to clearly and distinctly define the metes and bounds of the claim. 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 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. Claim 1 is provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claim 1 of copending Application No. 18/008,953 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because: Claim 1 is rejected under the judicially created doctrine of obviousness-type double patenting as being unpatentable over claim 1 of the reference. Amended claim 1 of the reference recites, inter alia, “wherein when the polymerase respectively acts upon each nucleotide of the plurality of nucleotides, such action maintains the label corresponding to that nucleotide at a location that is sufficiently close to the bridge for a sufficient amount of time to alter the labels corresponding to those nucleotides respectively altering an electrical characteristic of at least one of the first and second polymer chains.” Claim 1 of this unamended 371 application discloses substantially the same inventive concept involving a polymerase acting on nucleotides, labels associated with the nucleotides, and alteration of an electrical characteristic of the polymer chain(s) for detection. The amended limitation in claim 1 of the reference merely restates the same subject matter in a more specific form and would have been obvious to one of ordinary skill in the art. Accordingly, unamended claim 1, herein, is not patentably distinct from amended claim 1 of the reference. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented.
