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 .
According to paper filed on Jan. 6, 2026, the applicants have elected group II (claims 16-23) for further prosecution. The applicants have also elected compound 17 (disclosed on page 11 of specification) as specific species within compounds of formulae (I) and (II). The applicants have also amended claims 1 and 16.
Claims 1-2 and 16-23 are pending in the application. Claims 1-12 are withdrawn from further consideration as being directed to non-elected subject matter.
The elected species is allowable over the prior art. Therefore, search has now been extended to additional species of instant compounds of formulae (I) and (II).
Claim Rejections - 35 USC § 112
5. 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 16, 17, 19 and 21 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.
A broad range or limitation together with a narrow range or limitation that falls within the broad range or limitation (in the same claim) may be considered indefinite if the resulting claim does not clearly set forth the metes and bounds of the patent protection desired. See MPEP § 2173.05(c).
Claim 16 recites the broad recitation heteroaryl for the value of variable R3, and the claim also recites pyridinyl which is the narrower statement of the range/limitation.
Claim 17 recites the broad recitation C1-C6 alkyls for the values of variable R1, R2, R4 and R5, and the claim also recites preferably C1-C4 alkyls which is the narrower statement of the range/limitation.
Claim 19 recites the broad recitation C1-C6 alkyls for the values of variable R7, R8 and R9, and the claim also recites preferably C1-C4 alkyls which is the narrower statement of the range/limitation.
Claim 21 recites the broad recitation halogen for the values of variable R1, R2, R4 and R5, and the claim also recites preferably fluorine which is the narrower statement of the range/limitation.
The claim(s) are considered indefinite because there is a question or doubt as to whether the feature introduced by such narrower language is (a) merely exemplary of the remainder of the claim, and therefore not required, or (b) a required feature of the claims.
Claim Rejections - 35 USC § 102
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claim(s) 16-23 are rejected under 35 U.S.C. 102(a) (1) as being anticipated by Boschi (WO 2019/234186 A1, cited on applicant’s form 1449).
Boschi discloses HDHODH inhibitors. The compounds disclosed in claims 1-7 (specifically see claim 7) by Boschi anticipate the instant claims when variables X, Y and Z represent C in the instant compounds of formulae (I) and (II). It is of note that there is an additional inventor/applicant (Drug discovery and clinic) in the instant application as compared to WO 2019/234186 and therefore, inventive entity is different.
Claim(s) 16-23 are rejected under 35 U.S.C. 102(a) (1) as being anticipated by Sainas (J. Med. Chem., cited on applicant’s form 1449).
Sainas discloses dihydroorotate dehydrogenase inhibitors for treating leukemia. The compounds 4-10 disclosed in figure 2 (see page 6036) by sainas anticipate the instant claims when variables X, Y and Z represent C in the instant compounds of formulae (I) and (II).
(a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
Claims 16-23 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Boschi (WO 2019/234186 A1, cited on applicant’s form 1449).
Boschi discloses HDHODH inhibitors. The compounds disclosed in claims 1-7 (specifically see claim 7) by Boschi anticipate the instant claims when variables X, Y and Z represent C in the instant compounds of formulae (I) and (II).
The applied reference has a common inventor with the instant application. Based upon the earlier effectively filed date of the reference, it constitutes prior art under 35 U.S.C. 102(a)(2). This rejection under 35 U.S.C. 102(a)(2) might be overcome by: (1) a showing under 37 CFR 1.130(a) that the subject matter disclosed in the reference was obtained directly or indirectly from the inventor or a joint inventor of this application and is thus not prior art in accordance with 35 U.S.C. 102(b)(2)(A); (2) a showing under 37 CFR 1.130(b) of a prior public disclosure under 35 U.S.C. 102(b)(2)(B) if the same invention is not being claimed; or (3) a statement pursuant to 35 U.S.C. 102(b)(2)(C) establishing that, not later than the effective filing date of the claimed invention, the subject matter disclosed in the reference and the claimed invention were either owned by the same person or subject to an obligation of assignment to the same person or subject to a joint research agreement.
IMPROPER MARKUSH GROUP
Claims 16-23 are rejected on the basis that it contains an improper Markush grouping of alternatives. See In re Harnisch, 631 F.2d 716, 721-22 (CCPA 1980) and Ex parte Hozumi, 3 USPQ2d 1059, 1060 (Bd. Pat. App. & Int. 1984). A Markush grouping is proper if the alternatives defined by the Markush group (i.e., alternatives from which a selection is to be made in the context of a combination or process, or alternative chemical compounds as a whole) share a “single structural similarity” and a common use. A Markush grouping meets these requirements in two situations. First, a Markush grouping is proper if the alternatives are all members of the same recognized physical or chemical class or the same art-recognized class, and are disclosed in the specification or known in the art to be functionally equivalent and have a common use. Second, where a Markush grouping describes alternative chemical compounds, whether by words or chemical formulas, and the alternatives do not belong to a recognized class as set forth above, the members of the Markush grouping may be considered to share a “single structural similarity” and common use where the alternatives share both a substantial structural feature and a common use that flows from the substantial structural feature. See MPEP § 2117.
The Markush grouping of compounds of formulae (I) or (II) and formulae (III), (IV) and (V) is improper because the alternatives defined by the Markush grouping do not share a single structural similarity for the following reasons: The core structure of compounds of formulae (I) or (II) is structurally different based on the values of variables M, Q and Het.
To overcome this rejection, Applicant may set forth each alternative (or grouping of patentably indistinct alternatives) within an improper Markush grouping in a series of independent or dependent claims and/or present convincing arguments that the group members recited in the alternative within a single claim in fact share a single structural similarity as well as a common use.
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.
Claims 16-23 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-6, 8 and 20-25 of U.S. Patent No. 12,162,877. Although the claims at issue are not identical, they are not patentably distinct from each other because the compounds of the cited patent anticipate the instant claims when variables X, Y and Z represent C in the instant compounds of formulae (I) and (II).
