Claim Rejections[Symbol font/0xBE] Nonstatutory Obviousness-Type Double Patenting
5. Basis for nonstatutory 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. 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) 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.

6. Claims 1-19 are rejected on the ground of nonstatutory obviousness-type double patenting as being unpatentable over claims 1-20 of US Patent No. 11,890,350 B2. Although the conflicting claims are not identical, they are not patentably distinct from each other for the following reasons.
Claims 1-20 of US Patent No. 11,890,350 B2 are drawn to a pharmaceutical composition comprising a bile acid-peptide conjugate as a cytotoxic or cytostatic agent, the conjugate being free or releasably bound to a carrier molecule and being present in the pharmaceutical composition at an effective concentration of at least 40 micromolar, wherein the peptide comprised in the bile acid-peptide conjugate comprises a nuclear localization signal (NLS), wherein the bile acid-peptide conjugate when releasably bound to the carrier molecule is bound via an enzymatically cleavable linker, a photocleavable linker, a redox-sensitive linker, or a pH-sensitive linker, and wherein the carrier molecule is not a polypeptide antigen.
On the other hand, claims 1-19 of the instant application are drawn to a pharmaceutical composition comprising a steroid acid-peptide conjugate, the conjugate being free or releasably bound to a carrier molecule and being present in the pharmaceutical composition at an effective concentration sufficient to induce cytostasis or cytotoxicity, wherein the peptide comprised in the steroid acid-peptide conjugate comprises a nuclear localization signal (NLS), and wherein the carrier molecule is not a polypeptide antigen. Claims 1-20 of US Patent No. 11,890,350 B2 and claims 1-19 of the instant application vary in scope and are obvious over each other.
7. Claims 1-19 are provisionally rejected on the ground of nonstatutory obviousness-type double patenting as being unpatentable over claims 1, 5, 7-8, 10-11, 16, and 19 of copending Application No. 18/717,506. Although the conflicting claims are not identical, they are not patentably distinct from each other for the following reasons.
Claims 1, 5, 7-8, 10-11, 16, and 19 of copending Application No. 18/717,506 are drawn to a composition comprising a steroid acid-peptide conjugate covalently linked to and/or admixed with a cargo for intracellular delivery, wherein the peptide comprises a nuclear localization signal and the cargo is or comprises a protein, peptide, polynucleotide, polynucleotide analog, polysaccharide, drug, or any combination thereof, and wherein: (a) the cargo does not bind specifically to a cell surface receptor or ligand; (b) the cargo is not an antibody, and (c) the cargo is not or does not comprise an antigen.
On the other hand, claims 1-19 of the instant application are drawn to a pharmaceutical composition comprising a steroid acid-peptide conjugate, the conjugate being free or releasably bound to a carrier molecule and being present in the pharmaceutical composition at an effective concentration sufficient to induce cytostasis or cytotoxicity, wherein the peptide comprised in the steroid acid-peptide conjugate comprises a nuclear localization signal (NLS), and wherein the carrier molecule is not a polypeptide antigen.
It is noted that claims 1, 5, 7-8, 10-11, 16, and 19 of copending Application No. 18/717,506 use the term “cargo”, whereas 1-19 of the instant application use the term ‘carrier”. Claims 10 and 17 of the instant application limit the carrier to a protein carrier; a polysaccharide carrier; a polynucleotide carrier; a polynucleotide analog carrier; a polyethylene glycol carrier; or a lipid carrier. Thus, claims 1-19 of the instant application and claims 1, 5, 7-8, 10-11, 16, and 19 of copending Application No. 18/717,506 vary in scope and are obvious over each other.
Conclusions
8. No claims are allowed.
