OFFICE ACTION:
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 .
The preliminary amendments of 01/06/2023 have been entered in full. Claims 21-40 are pending and under consideration.
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.

Claims 21-24, 30, 32, 33, 36, 37, and 40 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-8 and 10-17 of U.S. Patent No. 12030924. Although the claims at issue are not identical, they are not patentably distinct from each other because the claims encompass overlapping subject matter as follows.
Both sets of claims encompass an exosome comprising a fusion protein, wherein the fusion protein comprises (i) an immunomodulating component and (ii) a prostaglandin F2 receptor negative regulator (PTGFRN) or a functional fragment thereof (patented claims 1 and 4, pending claim 21). Both sets encompass embodiments comprising more than one immunomodulating component (patented claims 5-7, 10-12). Both sets encompass embodiments wherein the fusion protein is present on the exterior surface of the microsome (patented claim 7, pending claims 21 and 33). In both sets, the immunomodulating component may be IL-15 (patented claim 3, pending claim 22). Both sets encompass embodiments wherein an immunomodulating component may be an activator for a positive co- stimulatory molecule or an activator for a binding partner of a positive co-stimulatory molecule (patented claim 2, pending claims 32 and 33). Pending claims 36, 37, and 40 recite that the composition comprising the claimed exosome comprises a pharmaceutically acceptable carrier, which is both implicit and obvious in view of patented claims 13-17, which recite methods of treating disease comprising administering the claimed exosome.
Claims 21, 22, 24, 25, 36, and 37 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1, 2, 5-7, 9, 10, 17, and 18 of U.S. Patent No. 10723782. Although the claims at issue are not identical, they are not patentably distinct from each other because the claims encompass overlapping subject matter as follows.
Both sets of claims encompass an exosome comprising a fusion protein, wherein the fusion protein comprises (i) an immunomodulating component and (ii) a prostaglandin F2 receptor negative regulator (PTGFRN) or a functional fragment thereof, wherein the an immunomodulating component comprises a cytokine (patented claims 1,2, and 7, pending claim 21). In both sets, the immunomodulating component may be IL-15 (patented claims 5 and 6, pending claim 22). Both sets encompass embodiments comprising full-length PTGFRN or a functional fragment comprising the region before the C-terminal-most IgV domain, the transmembrane domain, and the intracellular domain of PTGFRN (patented claims 17 and 18, pending claims 24 and 25). Both sets of claims encompass a composition comprising the claimed exosome of and a pharmaceutically- acceptable carrier (patented claim 9, pending claims 36 and 37).
Conclusion
Claims 21-25, 30, 32, 33, 36, 37, and 40 are rejected.
Claims 26-29, 31, 34, 35, and 39 are 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.
