Office Action

§112
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 . Claims 1-16 are presented for examination. Applicants’ information disclosure statement filed March 2, 2026 has been received and entered. Applicants’ response and terminal disclaimers filed April 13, 2026 have been received and entered. Accordingly, the rejection made under provisionally 35 USC 101 as claiming the same invention as that of claims 1-12 of copending Application No. 18/884,836 (reference application) as set forth in the previous Office action dated February 4, 2026 at pages 2-3 as applied to claims 1-12 is hereby WITHDRAWN because claims 1-12 were cancelled in copending Application No. 18/884,836. Accordingly, the rejection made under non-statutory double patenting as being unpatentable over claims 1, 10 and 11 of U.S. Patent No. 12,171,866 B2 as set forth in the previous Office action dated February 4, 2026 at pages 3-5 as applied to claims 1, 3, 4, and 12 is hereby WITHDRAWN because the applicants filed a terminal disclaimer. Accordingly, the rejections made under provisional non-statutory double patenting as being unpatentable over claims 77 and 92 of copending Application No. 17/059,932 (reference application) and claims 1 and 16 of copending Application No. 19/318,846 (reference application) as set forth in the previous Office action dated February 4, 2026 at pages 5-7 as applied to claims 1, 3-6, 9 and 12 are hereby WITHDRAWN because the applicants filed two terminal disclaimers. Claims 13-16 are withdrawn from consideration as being drawn to the non-elected invention (37 CFR 1.142(b)). Claim Objections Claims 2-8 and 10-12 are objected to as being dependent upon a rejected base claim 1. 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 claims 13-15 and 17 of copending Application No. 18/884,836 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because the present application teaches a lipid emulsion for parental nutrition comprising an aqueous phase and about 5% to about 35% by weight of an oil phase based on the total weight of the lipid emulsion (w/w) wherein the lipid emulsion comprises: from about 2.0 g/L to about 15.0 g/L of DHA; from about 0 g/L to about 1.2 g/L of EPA: and from about 5.0 g/L to about 20.0 g/L of ARA (A product), and the copending application teaches method of use claims and a multi-chamber bag containing the lipid emulsion of the present application therein which makes the composition claims of the present application an obvious variation of the copending application’s claims. Claim 1 is not allowed. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. 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. Claim 9 is 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. Claim 9 is rendered indefinite and vague by the phrase “□-tocopherol”. What is this compound? Should it be, -- α-tocopherol--. Correction is required. Claim 9 is not allowed.
