Claim Rejections - 35 USC § 112
The following is a quotation of the first paragraph of 35 U.S.C. 112(a):
(a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention.
The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112:
The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention.
Claims 1-16, 18 and 21-24 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. This is a written description rejection.
Claims 1-16, 18 and 21-24 encompass compounds of general Formula (I):

M.P.E.P. #2163 states: “An applicant shows possession of the claimed invention by describing the claimed invention with all of its limitations using such descriptive means as words, structures, figures, diagrams, and formulas that fully set forth the claimed invention….one must define a compound by ‘whatever characteristics sufficiently distinguish it’. A lack of adequate written description issue also arises if the knowledge and level of skill in the art would not permit one skilled in the art to immediately envisage the product claimed from the disclosed process”.
In Ariad Pharm., Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (en banc), the Federal Circuit stated that “the hallmark of written description is disclosure.” A specification adequately describes an invention when it “reasonably conveys to those skilled in the art that the inventor had possession of the claimed subject matter as of the filing date.” Id. at 1351. “A ‘mere wish or plan’ for obtaining the claimed invention is not adequate written description.” Centocor Ortho Biotech, Inc. v. Abbott Labs, 636 F.3d 1341, 1348 (Fed. Cir. 2011).
The description requirement of the patent statute requires a description of an actual invention, not merely an indication of a result that one might achieve if one made that invention. See, e.g., In re Wilder, 22 USPQ 369, 372-3 (Fed. Cir. 1984) (holding that a claim was not adequately described because the specification did ‘little more than outline goals appellants hope the claimed invention achieves and the problems the invention will hopefully ameliorate’). This matter is of particular importance in the evaluation of claims drawn to a chemical genus which identifies a core compound bearing variable substituents. It has been held that “a generic claim may define the boundaries of a vast genus of chemical compounds, and yet the question may still remain whether the specification...demonstrates that the applicant has invented species sufficient to support a claim to a genus” with such breadth. Ariad Pharmaceuticals, Inc. v. Eli Lilly & Co., 94 USPQ2D 1161, 1171 (Fed. Cir. 2010). An adequate written description requires a precise definition, such as by structure, formula, chemical name, physical properties, or other properties of species falling within the genus sufficient to distinguish the genus from other materials. Id., quoting Regents of the University of California v. Eli Lilly & Co., 119 F.3d 1559, 1568 (Fed. Cir. 1997).
However, merely drawing a fence around the outer limits of a purported genus is not an adequate substitute for describing a variety of materials constituting the genus and showing that one has invented a genus and not just a species. Ariad, 94 USPQ2D at 1171. 35 U.S. C. 112, first paragraph, requires a description of the invention that “clearly allow[s] persons of ordinary skill in the art to recognize that the inventor invented what is claimed.” Ariad at 1172, quoting Vas-Cath Inc. v. Mahurkar, 935 F.2d 1555 (1562-63) (Fed. Cir. 1991) (emphasis added). A sufficient disclosure is one which reasonably conveys to one having ordinary skill in the art that the inventor had possession of the claimed subject matter as of the filing date of the application in question. Vas-Cath, 935 F.2d at 1563. The description must reasonably describe the invention, not simply indicate a result which one might achieve if one actually made the invention. Eli Lilly, 119 F.3d at 1568. To properly evaluate whether an applicant has complied with the written description requirement therefore requires an analysis of whether the skilled artisan would recognize, from the description provided, the applicants were in possession of sufficient compounds representing the full breadth of diversity of the genus claimed.
A description of a chemical genus will usually comprise a recitation of structural features common to the members of the genus, which features constitute a substantial portion of the members of the genus, which features constitute substantial portion of the genus. See Univ. of California vs. Eli Lilly, 43 USPQ 2d 1398, 1406 (Fed. Cir. 1997). This is analogous to enablement of a genus under section 112 first, by showing enablement of a representative number of species within the genus. A chemical genus can be adequately described if the disclosure presents a sufficient number of representative species that encompass the genus. If the genus has a substantial variance, the disclosure must describe a sufficient number of species to reflect the variation within that genus.
Here, applicants have claimed an extraordinarily large genus of chemical compounds encompassed by general Formula (I). The specification discloses a list of 26 compounds that are encompassed by the general Formula (I) (see claim 17 and pages 47- 60 of the specification):

Wherein:
R1 is always Hydrogen, -CO-NHR, -CO-OR, -(CH2)3-CO-NHR or -(CH2)3-CO-OR,
R2 and R3 are always Chlorine, and
R4 is always -(CH2)3-OMe, -(CH2)-piperidine or -(CH2)-pyridine
The size of the genus claimed is phenomenal, against which the applicants have offered evidence of being in possession of about 26 compounds (see claim 17 and pages 47- 60 of the specification). This small set of compounds cannot be viewed as being reasonably representative of the genus of compounds of Formula (I) in its claimed scope because no readily apparent combination of identifying characteristics is provided, other than the disclosure of those specific species as examples of the claimed genus, and in no way either represent the breadth of variable moieties which applicants have claimed, nor permit the skilled artisan to recognize that such claim breadth was actually in the applicants possession as of the time of filing the instant application.
Given the broad scope of the claimed subject matter, Applicant has not provided sufficient written description that would allow the skilled in the art to recognize that Applicant was in possession of most the compounds of the above general Formula (I) claimed.
Claim Rejections - 35 USC § 112
The following is a quotation of the first paragraph of 35 U.S.C. 112(a):
(a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention.
The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112:
The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention.
Claim 21 is rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, because the specification, while being enabling for colon cancer comprising the administration of a compound of Formula (I), does not reasonably provide enablement for the treatment of any other type of cancer.
The specification does not enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to use the invention commensurate in scope with these claims. This is a scope of enablement rejection.
The factors that may be considered in determining whether a disclosure would require undue experimentation are set forth In re Wands, 8 USPQ2d 1400 (CAFC 1988) at 1404 wherein, citing Ex parte Forman, 230 USPQ 546 (Bd. Apls. 1986) at 547 the court recited eight factors:
1- the quantity of experimentation necessary,
2- the amount of direction or guidance provided,
3- the presence or absence of working examples,
4- the nature of the invention,
5- the state of the prior art,
6- the relative skill of those in the art,
7- the predictability of the art, and
8- the breadth of the claims
These factors are always applied against the background understanding that scope of enablement varies inversely with the degree of unpredictability involved. In re Fisher, 57 CCPA 1099, 1108, 427 F.2d 833, 839, 166 USPQ 18, 24 (1970). Keeping that in mind, the Wands factors are relevant to the instant fact situation for the following reasons:
1. The nature of the invention
Claim 21 recites: A method of treating cancer in a subject in need thereof,
comprising administering to said subject a therapeutically effective amount of a compound of Formula (I) as in claim 1.
2. The relative skill of those in the art
The relative skill of those in the art is high, generally that of an M.D. or Ph.D. The artisan using Applicant’s invention would generally be a physician with a M.D. degree and several years of experience.
3. The state and predictability of the art
A search of the literature reveals that the compounds of Formula (I) in claim 1 are novel and as such there is no prior biological/pharmacological data.
Further, there is no single known drug that can treat every single type of cancer
These articles plainly demonstrate that the treatment of any type of cancer with a single compound, is extremely unpredictable.
4. The breadth of the claims
Claim 21 is very broad in terms of the compounds of Formula (I) claimed and in terms of claiming every type of cancer.
5. The amount of direction or guidance provided and the presence or absence of working examples
MPEP 2164.03 states: “The scope of the required enablement varies inversely with the degree of predictability involved, but even in unpredictable arts, a disclosure of every operable species is not required. A single embodiment may provide broad enablement in cases involving predictable factors, such as mechanical or electrical elements. In re Vickers, 141 F.2d 522, 526-27, 61 USPQ 122, 127 (CCPA 1944); In re Cook, 439 F.2d 730, 734, 169 USPQ 298, 301 (CCPA 1971). However, in applications directed to inventions in arts where the results are unpredictable, the disclosure of a single species usually does not provide an adequate basis to support generic claims. In re Soll, 97 F.2d 623, 624, 38 USPQ 189, 191 (CCPA 1938). In cases involving unpredictable factors, such as most chemical reactions and physiological activity, more may be required. In re Fisher, 427 F.2d 833, 839, 166 USPQ 18, 24 (CCPA 1970) (contrasting mechanical and electrical elements with chemical reactions and physiological activity). See also In re Wright, 999 F.2d 1557, 1562, 27 USPQ2d 1510, 1513 (Fed. Cir. 1993); In re Vaeck, 947 F.2d 488, 496, 20 USPQ2d 1438, 1445 (Fed. Cir. 1991). This is because it is not obvious from the disclosure of one species, what other species will work”.
The specification provides biological data for the 26 compounds of Formula (I) in an in vitro assay that correlates with the efficacy in treating colon cancer (see specification pages 62-64).
The specification appears to be silent on a nexus between the effectiveness in this in vitro assay and the effectiveness in treating any type of cancer, besides colon cancer.
As such, if there is no correlation then the examples do not constitute working examples. While it is understood that the absence of working examples should never be the sole reason for rejecting a claim as being broader than an enabling disclosure, the criticality of working examples in an unpredictable art, such as the treatment of any cancer (other than colon cancer) comprising the administration of a compound of Formula (I), is required for practice of the claimed invention.
6. The quantity of experimentation necessary
As discussed above (see: 3. the state and predictability of the art), there is a high unpredictability in the art of treating any type of cancer comprising a single drug. Based on this and in the absence of experimental evidence commensurate in scope with the claims (see: 5. The amount of direction or guidance and the presence or absence of working examples above), the skilled in the art will not accept that the administration of a compound of Formula (I) will be effective in treating any type of cancer (except for colon cancer) as inferred by the claims and contemplated by the specification because neither the prior art nor the specification disclose a single in vitro or in vivo data that will correlate the biological activity of the compounds of Formula (I) with the treatment any cancer, except for colon cancer.
So, determining if the administration of a compound of Formula (I) will be effective in treating any type of cancer (except for colon cancer)., will require assaying this compound in different assays that correlate with the treatment of different types of cancer, and then further determine their efficacy in a validated animal model.
All this is undue experimentation given the limited guidance and direction provided by Applicants.
7. Conclusion
Accordingly, the invention of claim 21 does not comply with the scope of enablement requirement of 35 U.S.C 112, first paragraph, since to practice the claimed invention a person of ordinary skill in the art would have to engage in undue experimentation with no assurance of success.
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.
1) Claims 1-18 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-18 of copending Application No. 18/681,173 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because both applications claim the same or very similar compounds.
This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented.
2) Claims 21-24 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 19-22 of copending Application No. 18/681,173 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because both applications claim methods of treating cancer or methods of modulating the activity of RBM39 and/or DCAF15 comprising the administration of the same or similar compounds
This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented.
Conclusion
No claims are allowed.
