Nucleotide and/or Amino Acid Sequence Disclosures
REQUIREMENTS FOR PATENT APPLICATIONS CONTAINING NUCLEOTIDE AND/OR AMINO ACID SEQUENCE DISCLOSURES
Items 1) and 2) provide general guidance related to requirements for sequence disclosures.
37 CFR 1.821(c) requires that patent applications which contain disclosures of nucleotide and/or amino acid sequences that fall within the definitions of 37 CFR 1.821(a) must contain a "Sequence Listing," as a separate part of the disclosure, which presents the nucleotide and/or amino acid sequences and associated information using the symbols and format in accordance with the requirements of 37 CFR 1.821 - 1.825. This "Sequence Listing" part of the disclosure may be submitted:
In accordance with 37 CFR 1.821(c)(1) via the USPTO patent electronic filing system (see Section I.1 of the Legal Framework for Patent Electronic System (https://www.uspto.gov/PatentLegalFramework), hereinafter "Legal Framework") as an ASCII text file, together with an incorporation-by-reference of the material in the ASCII text file in a separate paragraph of the specification as required by 37 CFR 1.823(b)(1) identifying:
the name of the ASCII text file;
ii) the date of creation; and
iii) the size of the ASCII text file in bytes;
In accordance with 37 CFR 1.821(c)(1) on read-only optical disc(s) as permitted by 37 CFR 1.52(e)(1)(ii), labeled according to 37 CFR 1.52(e)(5), with an incorporation-by-reference of the material in the ASCII text file according to 37 CFR 1.52(e)(8) and 37 CFR 1.823(b)(1) in a separate paragraph of the specification identifying:
the name of the ASCII text file;
the date of creation; and
the size of the ASCII text file in bytes;
In accordance with 37 CFR 1.821(c)(2) via the USPTO patent electronic filing system as a PDF file (not recommended); or
In accordance with 37 CFR 1.821(c)(3) on physical sheets of paper (not recommended).
When a “Sequence Listing” has been submitted as a PDF file as in 1(c) above (37 CFR 1.821(c)(2)) or on physical sheets of paper as in 1(d) above (37 CFR 1.821(c)(3)), 37 CFR 1.821(e)(1) requires a computer readable form (CRF) of the “Sequence Listing” in accordance with the requirements of 37 CFR 1.824.
If the "Sequence Listing" required by 37 CFR 1.821(c) is filed via the USPTO patent electronic filing system as a PDF, then 37 CFR 1.821(e)(1)(ii) or 1.821(e)(2)(ii) requires submission of a statement that the "Sequence Listing" content of the PDF copy and the CRF copy (the ASCII text file copy) are identical.
If the "Sequence Listing" required by 37 CFR 1.821(c) is filed on paper or read-only optical disc, then 37 CFR 1.821(e)(1)(ii) or 1.821(e)(2)(ii) requires submission of a statement that the "Sequence Listing" content of the paper or read-only optical disc copy and the CRF are identical.
Specific deficiencies and the required response to this Office Action are as follows:

Claim Objections
Claims 1, 4-6, and 8 are objected to because of the following informalities:
Claim 1: “L is bond,” should read “L is a bond,”;
Claim 1: all instances of “subsitiuted” should read “substituted”;
Claim 1: in the definitions of Ra, Rb, Rc, Rd, Re, Rf, and “two of Rf groups”, both “=O” and “oxo” are listed as substituents, which mean the same thing;
Claims 4-6: “v1” is difficult to read as it overlaps with a bond;
Claim 8: “neorodegenerative” should read “neurodegenerative”.
Appropriate correction is required.
Claim Rejections – Improper Markush Grouping
Claims 1-8 are rejected on the judicially-created basis that they contain 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). The improper Markush grouping includes species of the claimed invention that do not share both a substantial structural feature and a common use that flows from the substantial structural feature.
A Markush claim contains an “improper Markush grouping” if: (1) the species of the Markush group do not share a single structural similarity,” or (2) the species do not share a common use. Members of a Markush group share a "single structural similarity” when they belong to the same recognized physical or chemical class or to the same recognized physical or chemical class or to the same art-recognized class. Members of a Markush group share a common use when they are disclosed in the Specification or known in the art to be functionally equivalent (see Federal Register, Vol. 76, No. 27, Wednesday, February 9, 2011, p. 7166, left and middle columns, bridging paragraph).
The members of the improper Markush grouping do not share a substantial feature and/or a common use that flows from the substantial structural feature for the following reasons:
The variable structure of Formula (I) is defined as seen below:
PNG
media_image2.png

media_image2.png
Greyscale
The structure of Formula (I) varies greatly in the identity of each cyclic group (Q3, Q4, Q5, Q7, and Q8) regarding the size, present or absence of heteroatoms, and whether they are monocyclic, fused, or spirocyclic. Additionally, Z2 is so broad that its full scope requires multiple searches as it reads on ring structures that are extremely large and/or variable.
Clearly no ‘‘single structural similarity’’ can be seen.
In response to this rejection, Applicant should either amend the claim(s) to recite only individual species or grouping of species that share a substantial structural feature as well as a common use that flows from the substantial structural feature, or present a sufficient showing that the species recited in the alternative of the claim(s) in fact share a substantial structural feature as well as a common use that flows from the substantial structural feature. This is a rejection on the merits and may be appealed to the Board of Patent Appeals and Interferences in accordance with 35 U.S.C. § 134 and 37 CFR41.31 (a) (1) (emphasis provided).
Claim Rejections - 35 USC § 112(b)
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 1-8 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.
Claims 1-8 recite “or a prodrug”. The term “prodrug” renders claims 1-8 indefinite as a prodrug does not have a defined structure known in the art. For example, one would not be apprised of the pharmacologically inactive form of the claimed compound from the simple recitation of “prodrug” as the compound itself has multiple cities to which a prodrug moiety could bind. Moreover, one could not ascertain as to which prodrug moieties are within the scope of the claim, resulting in millions of combinations. One could not possibly envisage all the possibilities of a prodrug of any compound of the instant invention.
Claim 1 recites “of said compound of Formula (I)”. This limitation lacks antecedent basis as the preamble of claim 1 recites “A compound of Formula (1)”. Correction is required. Claims 2-8 are rejected for not clarifying the limitation at issue.
Regarding claim 1, the phrase “e.g.” (or "for example") renders the claim indefinite because it is unclear whether the limitation(s) following the phrase are part of the claimed invention. See MPEP § 2173.05(d).
Claim 1 recites “said cycloalkyl, heterocycloalkyl, aryl, or heteroaryl of R3 or R4” and “said cycloalkyl, heterocycloalkyl, aryl, or heteroaryl of R4 or R5” and “said cycloalkyl, heterocycloalkyl, aryl, or heteroaryl of R5 or R6”. This causes confusion as the cycloalkyl, heterocycloalkyl, aryl, or heteroaryl is formed by the two R groups binding together, not one or the other. Should the claim read “of R3 and R4”, “of R4 and R5”, and “of R5 and R6”?
Claim 1 reads “said cycloalkyl, cycloalkenyl, heterocycloalkyl, heterocycloalkenyl, spiroheterocyclyl, fused heterocyclyl, bridged heterocyclyl, aryl, or heteroaryl of R7”. This causes confusion as the cycloalkyl, cycloalkenyl, heterocycloalkyl, heterocycloalkenyl, spiroheterocyclyl, fused heterocyclyl, bridged heterocyclyl, aryl, or heteroaryl is formed with R7 and -Z1-L-R9. Should the claim read “of R7 and -Z1-L-R9”?
Claims 3-6 define a and b as 0, 1, or 2. However, in claims 1 and 2, the variables a and b refer to the number of R1 and R2 substituents, respectively, on a ring, while in claim 3 the variables a and b refer both to the size of Q5 and the number of R1 and R2 substituents. Moreover, in claim 3, Formula (III) depicts a single R1 substituent which would be interpreted as “a is 1”. This causes confusion. It is additionally unclear whether the definitions for a and b in claim 3 are only meant to define the size of the spirocyclic ring in the Q5 position, or if they are also defining the number of R1 and R2 substituents.
Claims 4-6 define g as 0, 1, or 2. This causes confusion for the same reasons as given for claim 3 regarding a and b.
Claim 4 recites “A is O, S, SO2, N(Ra), or C(RaRb)”. The definition of A is not supported by the claims from which it depends (claim 3, which depends on claim 2, which depends on claim 1) wherein Q4 can only be substituted by R4, not Ra and/or Rb, which do not have the same scope as R4. Claims 5-6 are rejected for the same reasons.
Claims 7 and 8 recite “any one of Formulae (I)-(IV-B)… as defined in claim 1… or a prodrug of said compound of any one of Formulae (I)-(IV-B)”. However, claim 1 only sets forth Formula (I). Formulae (II)-(IV-B) lack antecedent basis.
Claim Rejections - 35 USC § 112(a)
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 1-8 are 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 a pharmaceutically acceptable salt, tautomer, , does not reasonably provide enablement for solvates, polymorphs, prodrugs, isotopic forms, or N-oxides. The specification does not enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make the invention commensurate in scope with these claims.
The claims are drawn to solvates, polymorphs, prodrugs, isotopic forms, or N-oxides of Formulae (I)-(IV-B). But the numerous examples presented in the instant specification all fail to produce a solvate, polymorph, prodrug, isotopic forms, or N-oxide. These cannot be simply willed into existence, nor are they predictable. Applicant additionally provides no guidance as to how a solvate, polymorph, prodrug, isotopic forms, or N-oxide would be made or what its characteristics would be (XRPD peaks, substituents, isotope identities and locations in the structure, etc.). One of ordinary skill in the art would not be able to arrive at any of these compounds without undue experimentation, absent any guidance or proof that they exist and can be made. As was stated in Morton International Inc. v. Cardinal Chemical Co., 28 USPQ2d 1190 “The specification purports to teach, with over fifty examples, the preparation of the claimed compounds with the required connectivity.” Hence, applicants must show that solvates, polymorphs, prodrugs, isotopic forms, and N-oxides can be made, or limit the claims accordingly.
Claim 8 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 alleviating or ameliorating the neoplastic diseases listed in the last paragraph of page 149 of the specification and the autoimmune diseases listed in the first paragraph of page 150 of the specification, does not reasonably provide enablement for treating, or curing, neoplastic, autoimmune, and neurodegenerative diseases generally. 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.
As a general rule, enablement must be commensurate with the scope of claim language. MPEP 2164.08 states, "The Federal Circuit has repeatedly held that "the specification must teach those skilled in the art how to make and use the full scope of the claimed invention without undue experimentation." In re Wright, 999 F.2d 1557, 1561, 27 USPQ2d 1510, 1513 (Fed. Cir. 1993)" (emphasis added). The "make and use the full scope of the invention without undue experimentation" language was repeated in 2005 in Warner-Lambert Co. v. Teva Pharmaceuticals USA Inc., 75 USPQ2d 1865, and Scripps Research Institute v. Nemerson, 78 USPQ2d 1019 asserts: "A lack of enablement for the full scope of a claim, however, is a legitimate rejection." The principle was explicitly affirmed most recently in Liebel-Flarsheim Co. v. Medrad, Inc., 481 F.3d 1371, 82 USPQ2d 1113; Auto. Tech. Int'l, Inc. v. BMW of N. Am., Inc., 501 F.3d 1274, 84 USPQ2d 1108 (Fed. Cir. 2007), Monsanto Co. v. Syngenta Seeds, Inc., 503 F.3d 1352, 84 U.S.P.Q.2d 1705 (Fed. Cir. 2007), and Sitrick v. Dreamworks, LLC, 516 F.3d 993, 85 USPQ2d 1826 (Fed. Cir. 2008).
Pursuant to In re Wands, 858 F.2d 731, 737, 8 USPQ2d 1400, 1404 (Fed. Cir. 1988), one considers the following factors to determine whether undue experimentation is required: (A) The breadth of the claims; (B) The nature of the invention; (C) The state of the prior art; (D) The level of one of ordinary skill; (E) The level of predictability in the art; (F) The amount of direction provided by the inventor; (G) The existence of working examples; and (H) The quantity of experimentation needed to make or use the invention based on the content of the disclosure. Some experimentation is not fatal; the issue is whether the amount of experimentation is "undue"; see In re Vaeck, 20 USPQ2d 1438, 1444.
The treatment of cancer generally cannot possibly be considered enabled.
The treatment of autoimmune and neurodegenerative diseases generally cannot possibly be considered enabled.
By way of background, four cases are of particular relevance to the question of enablement of a method of treating cancers broadly or even generally:
In In re Buting, 57 CCPA 777, 418 F.2d 540, 163 USPQ 689, the claim was drawn to "The method of treating a malignant condition selected from the group consisting of leukemias, sarcomas, adenocarcinomas, lymphosarcomas, melanomas, myelomas, and ascitic tumors" using a small genus of compounds. The Court decided that human testing "limited to one compound and two types of cancer" was not "commensurate with the broad scope of utility asserted and claimed".
In Ex parte Jovanovics, 211 USPQ 907 the claims were drawn to "the treatment of certain specified cancers in humans" by the use of a genus of exactly two compounds, the N-formyl or N-desmethyl derivative of leurosine. Applicants submitted "affidavits, publications and data" for one of the compounds, and a dependent claim drawn to the use of that species was allowed. For the other, no data was presented, applicants said only that the other derivative would be expected to be less effective; claims to the genus were refused.
In Ex parte Busse, et al., 1 USPQ2d 1908, claims were drawn to "A therapeutic method for reducing metastasis and neoplastic growth in a mammal" using a single species. The decision notes that such utility "is no longer considered to be "incredible", but that "the utility in question is sufficiently unusual to justify the examiner's requirement for substantiating evidence. Note also that there is also a dependent claim 5 which specified "wherein metastasis and neoplastic growth is adenocarcinoma, squamous cell carcinoma, melanoma, cell small lung or glioma." The decision notes that "even within the specific group recited in claim 5 some of the individual terms used actually encompass a relatively broad class of specific types of cancer, which specific types are known to respond quite differently to various modes of therapy."
In Ex parte Stevens, 16 USPQ2d 1379 a claim to "A method for therapeutic or prophylactic treatment of cancer in mammalian hosts" was refused because there was "no actual evidence of the effectiveness of the claimed composition and process in achieving that utility."
Pursuant to In re Wands, 858 F.2d 731, 737, 8 USPQ2d 1400, 1404 (Fed. Cir. 1988), one considers the following factors to determine whether undue experimentation is required: (A) The breadth of the claims; (B) The nature of the invention; (C) The state of the prior art; (D) The level of one of ordinary skill; (E) The level of predictability in the art; (F) The amount of direction provided by the inventor; (G) The existence of working examples; and (H) The quantity of experimentation needed to make or use the invention based on the content of the disclosure. Some experimentation is not fatal; the issue is whether the amount of experimentation is "undue"; see In re Vaeck, 20 USPQ2d 1438, 1444.
The analysis is as follows:
1) Breadth of claims.
"Cancer" is not a single disease, or cluster of closely related disorders. There are hundreds of cancers, which have in common only some loss of controlled cell growth. Cancers are highly heterogeneous at both the molecular and clinical level, something seen especially in, for example, the cancers of the breast, brain and salivary glands. They can occur in pretty much every part of the body. To be able to simply stop cancer cells generally from being able to proliferate. Many of these approaches --- and there have been others as well --- have produced anti-cancer drugs. However, despite high hopes for success, and a plausible theory why these should work for cancers generally, none of these approaches have ever produced a drug which come remotely near such a goal.
Specifically, the prior art knows that there never has been a compound capable of treating cancers generally. "The cancer therapy art remains highly unpredictable, and no example exists for efficacy of a single product against tumors generally." (<http://www.uspto.gov/web/offices/pac/dapp/1pecba.htm#7> ENABLEMENT DECISION TREE, Example F, situation 1). A similar statement appears at In re Application of Hozumi et al., 226 USPQ 353: "In spite of the vast expenditure of human and capital resources in recent years, no one drug has been found which is effective in treating all types of cancer. Cancer is not a simple disease, nor is it even a single disease, but a complex of a multitude of different entities, each behaving in a different way". There are compounds that treat a modest range of cancers, but no one has ever been able to figure out how to get a compound to be effective against cancer generally, or even a majority of cancers.
The attempts to find compounds to treat the various cancers arguably constitute the single most massive enterprise in all of pharmacology. This has not resulted in finding any treatment for tumors generally. Indeed, the existence of such a "silver bullet" is contrary to our present understanding in oncology. This is because it is now understood that there is no "master switch" for cancers generally; cancers arise from a bewildering variety of differing mechanisms. Even the most broadly effective antitumor agents are only effective against a small fraction of the vast number of different cancers known. This is true in part because cancers arise from a wide variety of sources, primarily a wide variety of failures of the body's cell growth regulatory mechanisms, but also such external factors such as viruses (an estimated at least 20% are of viral origin e.g. Human papillomavirus, EBV, Hepatitis B and C, HHV-8, HTLV-1 and other retroviruses, and quite possibly Merkel cell polyomavirus, and there is some evidence that CMV is a causative agent in glioblastoma), exposure to chemicals such as tobacco tars, excess alcohol consumption (which causes hepatic cirrhosis, an important cause of HCC), ionizing radiation, and unknown environment factors.
Accordingly, there is substantive "reason for one skilled in the art to question the objective truth of the statement of utility or its scope" (In re Langer, 183 USPQ 288, 297), specifically, the scope of covering cancer generally.
Similarly, In re Novak, 134 USPQ 335, 337-338, says "unless one with ordinary skill in the art would accept those allegations as obviously valid and correct, it is proper for the examiner to ask for evidence which substantiates them." There is no such evidence in this case. Likewise, In re Cortright, 49 USPQ2d 1464, states: "Moreover, we have not been shown that one of ordinary skill would necessarily conclude from the information expressly disclosed by the written description that the active ingredient" does what the specification surmises that it does. That is exactly the case here. Moreover, even if applicants' assertion that cancer in general could be treated with these compounds were plausible --- which it is not ---, that "plausible" would not suffice, as was stated in Rasmusson v. SmithKline Beecham Corp., 75 USPQ2d 1297, 1301: "If mere plausibility were the test for enablement under section 112, applicants could obtain patent rights to "inventions" consisting of little more than respectable guesses as to the likelihood of their success."
Different types of cancers affect different organs and have different methods of growth and harm to the body, and different vulnerabilities. The skill thus depends on the particular cancer involved. There are some cancers where the chemotherapy skill level is high and there are multiple successful chemotherapeutic treatments. The mechanism in these situations, however, is not necessarily the same as is alleged for these compounds.
One skilled in the art knows that chemotherapy of brain tumors is especially difficult. This is because 1) the blood-brain barrier, which is often intact in parts or all of a brain tumor, will block out many drugs, as it is the purpose of the blood-brain barrier to protect the brain from alien chemicals, and 2) CNS tumors are characterized by marked heterogeneity, which greatly decreases vulnerability to chemotherapy. As a result, many categories of CNS tumors simply have no chemotherapy available. These include, generally, hemangioblastomas, meningiomas, craniopharyngiomas, acoustic neuromas, pituitary adenomas, optic nerve gliomas, glomus jugulare tumors and chordomas, to name just some. With regard to gliomas, GBM is considered untreatable; no effective agents have emerged for the treatment of GBM, despite 20 years of enrolling patients in clinical trials. It is radiation and surgery which are used for low grade gliomas (e.g. pilocytic astrocytoma and diffuse astrocytomas), as no drug has been found effective. There is no drug treatment established as effective for optic nerve gliomas or gangliogliomas. Indeed, very few gliomas of any type are treated with pharmaceuticals; it is one of the categories of cancer that is the least responsive to drugs.
Lymphomas of the stomach are not commonly treated with anti-cancer agents per se, but instead, surgery or radiation and antibiotic therapy (e.g. amoxicillin, metronidazole, bismuth, and omeprazole) are the primary treatments.
Neuroendocrine tumors of the cervix generally do not respond to chemotherapy.
A number of sarcomas, including alveolar soft part sarcoma (ASPS), retroperitoneal sarcoma, most liposarcomas, and the assorted chondrosarcomas, are generally considered not to respond to chemotherapy; no chemotherapeutic agent has been established as effective.
It is important to note that tumors can need to be treated quite differently even though they are tumors of the same organ. For example, the drugs used most often to treat Wilms tumor, the most common malignant tumor of the kidneys in children, are actinomycin D and vincristine. Such drugs are never used with clear cell renal carcinoma, which is treated, although without much success, with immunotherapy using the cytokines interleukin-2 and interferon-alpha. However, such immunotherapy has never been established as effective in non-clear cell RCC forms such as papillary renal cell carcinoma. Despite strenuous efforts over a period of decades, no chemotherapeutic agent has ever been found effective against this cancer. Cancers of the stomach can be lymphomas, GISTs, carcinoid tumors, carcinomas, or soft tissue sarcomas, and for a single agent to be effective against all or even most of these categories would be contrary to what is known in oncology.
The scope of treating inflammation generally is extraordinarily broad. Inflammation is a process which can take place in virtually any part of the body. There is a vast range of forms that it can take, causes for the problem, and biochemical pathways that mediate the inflammatory reaction. It is one of the most pervasive of all body processes. Inflammation is a very general term which encompasses a huge variety of specific processes.
The scope of "neurodegenerative disorder" cannot be deemed enabled. The term "neurodegenerative disorder" covers a broad array of different disorders that have different modes of action and different origins. The term covers such diverse disorders as Alzheimer's Disease; Parkinson's Disease; ALS and variants such as forms of ALS-PDC; Gerstmann-Straussler-Scheinker Disease (GSS); Pick's Disease; Diffuse Lewy Body Disease; Hallervordon-Spatz disease; progressive familiar myoclonic epilepsy; Corticodentatonigral degeneration; progressive supranuclear palsy (Steele-Richardson-Olszewski); Huntington's disease; more than a dozen dementias collectively called "frontotemporal dementia and Parkinsonism linked to chromosome 17" (FTDP-17); Tourette's syndrome; Shy-Drager syndrome; Friedrich's ataxia and other spinocerebellar degenerations; Olivopontocerebellar atrophy (OPCA); spasmotic torticollis; Striatonigral degeneration; various types of torsion dystonia; certain spinal muscular atrophies, such as Werdnig-Hoffmann and Wohlfart-Kugelberg-Welander; Hereditary spastic paraplegia, Primary lateral sclerosis; peroneal muscular atrophy (Charcot-Marie-Tooth); Creutzfeldt-Jakob Disease (CJD); Hypertrophic interstitial polyneuropathy (Dejerine-Sottas); retinitis pigmentosa; Leber's Disease; and Hypertrophic interstitial polyneuropathy. These exhibit a very broad range of effects and origins.
For example, some give progressive dementia without other prominent neurological signs, such as Alzheimer's disease, whereas other dementias have such signs, such as Diffuse Lewy Body Disease. Some give muscular wasting without sensory changes, e.g., ALS, and some do have the sensory changes such as Werdnig-Hoffmann. Some are abnormalities of posture, movement or speech, such as Striatonigral degeneration, and other are progressive ataxias, such as OPCA. Some are linked to tau mutations, such as Alzheimer's disease and FTDP-17, and other such as Parkinson's clearly do not. Some affect only vision such as retinitis pigmentosa. Even within those that fall into the same category of effects, there are often striking differences. For example, Alzheimer's disease and Pick's disease both give progressive dementia without other prominent neurological signs. But the characteristic Alzheimer's neurofibrillary tangles are not seen in Pick's Disease, which has straight fibrils, as opposed to the paired helical filaments of Alzheimer's disease. Pick's Disease gives lobal atrophy, not seen in Alzheimer's disease. There are differences in origins, even with what little is known. Thus, among progressive dementias, CJD is definitely caused by an infectious agent; so far as can be determined, this is not so for Huntington's disease. Even among the hereditary disorders, the origins are different. Thus, FTDP-17 comes from chromosome 17, Huntington's disease from 4, and the neurodegenerative disorder that people with Down's syndrome develop later in life is presumably connected in some way to 21.
2) The nature of the invention and predictability in the art.
With specific reference to cancer, Ex parte Kranz, 19 USPQ2d 1216, 1219 notes the "general unpredictability of the field [of] …anti-cancer treatment." In re Application of Hozumi et al., 226 USPQ 353 notes the "fact that the art of cancer chemotherapy is highly unpredictable". More generally, the invention is directed toward medicine and is therefore physiological in nature. It is well established that "the scope of enablement varies inversely with the degree of unpredictability of the factors involved," and physiological activity is generally considered to be an unpredictable factor. See In re Fisher, 427 F.2d 833, 839, 166 USPQ 18, 24 (CCPA 1970).
The great majority of neurodegenerative diseases have no treatment at all, and of those that do, none or virtually none have been treated with such inhibitors as are disclosed here. The great diversity of diseases falling within the "neurodegenerative disorder" category means that it is contrary to medical understanding that any agent (let alone a genus of trillions of compounds) could be generally effective against such diseases. The intractability of these disorders is clear evidence that the skill level in this art is low relative to the difficulty of the task. Further, what little success there has been does not point in this direction. Thus, what very few treatments that the massive research effort on Alzheimer's disease has produced are means of providing Acetylcholinesterase inhibition, unrelated to the mechanism of action in this case.
3) State of the Prior Art. The claimed compounds are of Formula (I). So far as the examiner is aware these compounds have not been successfully used as broad range anticancer agents or agents for treatment of autoimmune and/or neurodegenerative diseases generally.
4) Working Examples. Applicants have provided no working examples which are successfully used as broad range anticancer agents or agents for treatment of autoimmune and/or neurodegenerative diseases. Applicants have, however, demonstrated the cytotoxicity of compounds of the instant invention against an acute lymphoblastic leukemia cell line (p. 428-430 of specification).
5) Skill of those in the art. Many, many mechanisms have been proposed over the decades as methods of treating the assorted cancers generally. Cytotoxic agents could be applied directly to the tumors cells, directly killing them. Immunotherapy involves stimulating the patient's immune system to attack cancer cells generally, either by immunization of the patient, in which case the patient's own immune system is trained to recognize tumor cells as targets, or by the administration of therapeutic antibodies as drugs, so the patient's immune system is recruited to destroy tumor cells by the therapeutic antibodies. Another approach would be to increase the amount or activity of the body's tumor suppressor genes, e.g. p53, PTEN, APC and CD95, which can for example activate DNA repair proteins, suppress the Akt/PKB signaling pathway, or initiate apoptosis of cancer cells. The angiogenesis inhibitor strategy was based on cutting off the blood supply that growing tumors need by shutting off the growth of new blood vessels by, for example, suppressing proliferation of endothelial cells or inducing apoptosis of endothelial cells. There is also the cancer stem cell paradigm, which hypothesizes that cancer could be treated generally, either by targeting the cancer stem cells themselves, or by targeting the epithelial-to-mesenchymal transition which supposedly generates the cancer stem cells. Yet another approach is to inhibit one or more of the assorted HSP90 proteins, which will supposedly disrupt the proper folding of signaling proteins that all cancers rely on. Inhibiting telomerase was said to be able to be able to simply stop cancer cells generally from being able to proliferate. Many of these approaches --- and there have been others as well --- have produced anti-cancer drugs. However, despite high hopes for success, and a plausible theory why these should work for cancers generally, none of these approaches have ever produced a drug which come remotely near such a goal.
Accordingly, there is substantive "reason for one skilled in the art to question the objective truth of the statement of utility or its scope" (In re Langer, 183 USPQ 288, 297), specifically, the scope of covering cancer generally. Moreover, even if applicants' assertion that cancer in general could be treated with these compounds were plausible --- which it is not ---, that "plausible" would not suffice, as was stated in Rasmusson v. SmithKline Beecham Corp., 75 USPQ2d 1297, 1301: "If mere plausibility were the test for enablement under section 112, applicants could obtain patent rights to "inventions" consisting of little more than respectable guesses as to the likelihood of their success."
6) Scope of the claims. The scope of the claims involves the compounds of the following formula:

and their use as potential treatment to neoplastic, autoimmune, and neurodegenerative diseases, thus, the scope of claims is very broad.
7) The quantity of experimentation needed. Given the fact that, historically, the development of new drugs for the treatment of cancers, autoimmune diseases, and neurodegenerative diseases has been difficult and time consuming, and especially in view of factors 1 and 4 and 6, the quantity of experimentation needed is expected to be great.
MPEP 2164.01(a) states, "A conclusion of lack of enablement means that, based on the evidence regarding each of the above factors, the specification, at the time the application was filed, would not have taught one skilled in the art how to make and/or use the full scope of the claimed invention without undue experimentation. In re Wright, 999 F.2d 1557, 1562, 27 USPQ2d 1510, 1513 (Fed. Cir. 1993)." That conclusion is clearly justified here.
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.

Additionally, when making obviousness-type double patenting decisions, the Federal Circuit has stated, “[O]bviousness-type double patenting encompasses any use for a compound that is disclosed in the specification of an earlier patent claiming the compound and is later claimed as a method of using that compound”. Sun Pharm. Indus., Ltd. v. Eli Lilly & Co., 611 F.3d 1381 (Fed. Cir. 2010).
The specification of the ‘950 patent discloses that the claimed compounds can be used to treat neoplastic, autoimmune, and neurodegenerative diseases (col. 6). Therefore, since the claims of the ‘950 patent substantially overlap in scope with the instant invention, it would be prima facie obvious for one of ordinary skill in the art to arrive at the instant invention.
Claims 1-8 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-17 and 28-29 of U.S. Patent No. 12,220,419 B2. Although the claims at issue are not identical, they are not patentably distinct from each other because the claims are directed to the following genus, compositions thereof, and a method of treating neoplastic, autoimmune, and neurodegenerative diseases.
