without traverse. This compound appears to be compound ID 3 from claim 13.
Claim 20 has been amended to depend from Claim 1, hence, the rejoinder.
Claims 3, 4, 8, 10, 11, 16, 17, 22, 23, 25-49, 51, 52, 56, 59, 60, 62, 67-69 and 71-76 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected inventions and species, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on 09/18/2025.
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, 6, 7, 9, 12-15, 18-20, 22-36, 41-45, 50, 53, 55, 57, 58, 61, 63-66 and 70 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.
This rejection has been withdrawn in view of the Amendment filed 04/30/2026.
Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(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 1, 6, 7, 9, 12, 14, 15, 19, 20, 22-36, 41-45, 50, 53, 55, 57, 58, 61, 63-66 and 70 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by WO 2019/038717 A1 (WO ‘717).
This rejection has been withdrawn in view of the Amendment filed 04/30/2026.
Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claims 1, 6, 7, 9, 12, 14, 15, 18-20, 50, 53, 55, 57, 58, 61, 63-66 and 70 are rejected under 35 U.S.C. 103 as being unpatentable over Greig et al. US 20150359784 A1, in view of Man et al. Bioorganic & Medicinal Chemistry Letters 13 (2003).
Greig teaches a compound having formula below:

Greyscale
where R8 is hydrogen, hydroxyl, acyl, substituted acyl, acyloxy, substituted acyloxy, alkyl, substituted alkyl, alkenyl, substituted alkenyl, alkynyl, substituted alkynyl, alkoxy, substituted alkoxy, aryl, substituted aryl, amino, substituted amino, halogen, heterocycloalkyl, substituted heterocycloalkyl, heteroaryl, substituted heteroaryl, or a thio-containing group. See page 1 and 5-6. The disclosed compounds include one or more asymmetric centers, thus, these compounds can exist in different stereoisomeric forms. Accordingly, compounds and compositions may be provided as individual pure enantiomers or as stereoisomeric mixtures, including racemic mixtures. In certain embodiments the compounds disclosed herein are synthesized in or are purified to be in substantially enantiopure form, such as in a 90% enantiomeric excess, a 95% enantiomeric excess, a 97% enantiomeric excess or even in greater than a 99% enantiomeric excess, such as in enantiopure form. See paragraph 0060.
Greig does not expressly teach the alpha-fluoro-substituted thalidomide analogues. However, alpha-fluoro-substituted thalidomide analogues is known in the art. See for example the teaching in Man et al.
Thus, it would have been prima facie obvious to one of ordinary skill in the art to optimize the teaching in Greig in view of the teaching in Man with the expectation to obtain a thalidomide derivative or analogue useful for the treatment of cancer. This is because Man teaches the use of an alpha-substituted thalidomide compound for the treatment of a wide variety of diseases including tumor is known in the art.
Response to Arguments
Applicant’s arguments filed 04/30/2026 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument.
Allowable Claims
Claim 13 is 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.
Conclusion
Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
