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 .
Status of the claims
Claims 1-21 are pending and are examined.
Information Disclosure Statement
The information disclosure statements (IDS)s submitted on 09/27/2021 and 04/24/2024 were considered by the examiner.
The listing of references in the specification is not a proper information disclosure statement.  37 CFR 1.98(b) requires a list of all patents, publications, or other information submitted for consideration by the Office, and MPEP § 609.04(a) states, the list may not be incorporated into the specification but must be submitted in a separate paper.  Therefore, unless the references have been cited by the examiner on form PTO-892, they have not been considered.
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 1-21 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 claims contain 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 inventors, at the time the application was filed, had possession of the claimed invention.
“[T]he purpose of the written description requirement is to ‘ensure that the scope of the right to exclude, as set forth in the claims, does not overreach the scope of the  inventor’s contribution to the field of art as described in the patent specification.’” Ariad Pharm., Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1353-54 (Fed. Cir. 2010) (en banc) (quoting Univ. of Rochester v. G.D. Searle & Co., 358 F.3d 916, 920 (Fed. Cir. 2004)).  To satisfy the written description requirement, the specification must describe the claimed invention in sufficient detail that one skilled in the art can reasonably conclude that the inventor had possession of the claimed invention. Vas-Cath, Inc. v. Mahurkar, 935 F.2d 1555, 1562-63, 19 USPQ2d 1111 (Fed. Cir. 1991).  See also MPEP 2163.04.
“[A] sufficient description of a genus . . . requires the disclosure of either a representative number of species falling within the scope of the genus or structural features common to the members of the genus so that one of skill in the art can ‘visualize or recognize’ the members of the genus.” Ariad, 598 F.3d at 1350 (quoting Eli Lilly, 119 F.3d at 1568-69).  A “representative number of species” means that those species that are adequately described are representative of the entire genus.  AbbVie Deutschland GMBH v. Janssen Biotech, 111 USPQ2d 1780, 1790 (Fed. Cir. 2014).
In Amgen Inc. v. Sanofi, 124 USPQ2d 1354 (Fed. Cir. 2017), relying upon Ariad Pharms., Inc. v. Eli Lily & Co., 94 USPQ2d 1161 (Fed Cir. 2010), it is noted that to show invention, a patentee must convey in its disclosure that is “had possession of the claimed subject matter as of the filing date. Demonstrating possession “requires a precise definition” of the invention. To provide this precise definition” for a claim to a genus, a patentee must disclose “a representative number of species within the scope of the genus of structural features common to the members of the genus so that one of skill in the art can visualize or recognize the member of the genus” (see Amgen at page 1358).
Also, it is not enough for the specification to show how to make and use the invention, i.e., to enable it (see Amgen at page 1361).
In the instant case, the claims are drawn to a genus of methods of treatment of IL1RAP mediated diseases. The diseases claimed comprise: acne, acute pancreatitis, acute severe ulcerative colitis, adult-onset Still's disease, age-related macular degeneration (MJID), airway hyperresponsiveness, airway inflammation, allergic conjunctivitis, allergic rhinitis, allergy, Alzheimer's disease, amyotrophic lateral sclerosis (ALS), anaphylaxis, arthritis pain, asthma, atherosclerosis, atopic dermatitis, atopic eczema, autoimmune vasculitis, Behcet's disease, bone cancer, brain cancer, breast cancer, cachexia/anorexia, cartilage damage, cerebral ischemia, chronic fatigue syndrome, chronic obstructive pulmonary disease, Clostridium associated illnesses, colon cancer, congestive heart failure, conjunctivitis, coronary artery bypass graft, coronary restenosis, Crohn's disease, diabetes, diabetic macular edema, diabetic retinopathy, dry eye disease, endometriosis, eosinophil-associated gastrointestinal disorder, eosinophilic esophagitis, familial cold autoinflammatory syndrome, familial Mediterranean fever, fever, fibromyalgia, fibrotic disorder, food allergy, generalized pustular psoriasis, glaucoma, glomerulonephritis, gouty arthritis, graft versus host disease, helminth infection, hemorrhagic shock, hidradenitis suppurativa, hyperalgesia, hyper-lgD syndrome, hyperuricemia, idiopathic pulmonary fibrosis (IPF), cancer-related pain, infection, inflammatory bowel disease (I8D), inflammatory conditions resulting from strain, inflammatory eye disease associated with corneal transplant, inflammatory pain, influenza, intestinal cancer, ischemia, juvenile arthritis, Kawasaki's disease, kidney cancer, Leber’s congenital amaurosis, liver cancer, liver disease, lung cancer, Muckle-Wells syndrome, multiple myeloma, multiple sclerosis, musculoskeletal pain, myelogenous and other leukemias, myocardial dysfunction, myopathies, nasal polyp, neonatal onset multisystem inflammatory disease, neurotoxicity, non-infectious conjunctivitis, non-small cell lung cancer, orthopedic surgery, osteoarthritis, osteoporosis, pain, palmoplantar pustulosis, pancreas cancer, Parkinson's disease, periodontal disease, peripheral vascular disease, polymyalgia rheumatica, polypoidal choroidal vasculopathy (PCV), pre-term labor, prostate cancer, protozoan infection, psoriasis, psoriatic arthritis, pyoderma gangrenosum, reperfusion injury, respiratory syncytial virus (RSV), restenosis, retinal detachment, retinitis pigmentosa, retinopathy of prematurity (ROP), rheumatoid arthritis, septic shock, sickle-cell anemia, side effects from radiation therapy, sinusitis, skin cancer, sleep disturbance, sprain, Stargardt's disease, stomach cancer, temporal mandibular joint disease, TNF receptor associated periodic syndrome, transplant rejection, trauma, traumatic eye injury, type-2 diabetes, ulcerative colitis, and uveitis. This extensive menu of diseases claimed to be treated are not backed by any data showing even a bare bones method (administration regimen, dose, length of treatment and metrics for assessing the efficacy of the treatment). There is no indication that any of the diseases claimed were treated. The only method that Applicant is in possession of is an in vitro method of blocking IL1RAP activity with antibody 14F4 (example 17) and an in vivo method of blocking complex phenotypes induced in mouse models of asthma ([0490]).
Given the complexity of the diseases claimed and the lack of guidance and working examples, a person of ordinary skill in the art would conclude that the genus of methods claimed were not in Applicant’s possession. In the best case scenario, Applicant may be in possession of a method of treating asthma with the antibodies claimed.
Claims 1-21 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 treating asthma with the antibodies claimed in the independent claim 1, does not reasonably provide enablement for treating all diseases IL1RaP mediated diseases.  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.
The claims are drawn to a genus of methods of treatment of IL1RAP mediated diseases. The diseases claimed comprise acne, acute pancreatitis, acute severe ulcerative colitis, adult-onset Still's disease, age-related macular degeneration (MJID), airway hyperresponsiveness, airway inflammation, allergic conjunctivitis, allergic rhinitis, allergy, Alzheimer's disease, amyotrophic lateral sclerosis (ALS), anaphylaxis, arthritis pain, asthma, atherosclerosis, atopic dermatitis, atopic eczema, autoimmune vasculitis, Behcet's disease, bone cancer, brain cancer, breast cancer, cachexia/anorexia, cartilage damage, cerebral ischemia, chronic fatigue syndrome, chronic obstructive pulmonary disease, Clostridium associated illnesses, colon cancer, congestive heart failure, conjunctivitis, coronary artery bypass graft, coronary restenosis, Crohn's disease, diabetes, diabetic macular edema, diabetic retinopathy, dry eye disease, endometriosis, eosinophil-associated gastrointestinal disorder, eosinophilic esophagitis, familial cold autoinflammatory syndrome, familial Mediterranean fever, fever, fibromyalgia, fibrotic disorder, food allergy, generalized pustular psoriasis, glaucoma, glomerulonephritis, gouty arthritis, graft versus host disease, helminth infection, hemorrhagic shock, hidradenitis suppurativa, hyperalgesia, hyper-lgD syndrome, hyperuricemia, idiopathic pulmonary fibrosis (IPF), cancer-related pain, infection, inflammatory bowel disease (I8D), inflammatory conditions resulting from strain, inflammatory eye disease associated with corneal transplant, inflammatory pain, influenza, intestinal cancer, ischemia, juvenile arthritis, Kawasaki's disease, kidney cancer, Leber’s congenital amaurosis, liver cancer, liver disease, lung cancer, Muckle-Wells syndrome, multiple myeloma, multiple sclerosis, musculoskeletal pain, myelogenous and other leukemias, myocardial dysfunction, myopathies, nasal polyp, neonatal onset multisystern inflammatory disease, neurotoxicity, non-infectious conjunctivitis, non-small cell lung cancer, orthopedic surgery, osteoarthritis, osteoporosis, pain, palmoplantar pustulosis, pancreas cancer, Parkinson's disease, periodontal disease, peripheral vascular disease, polymyalgia rheumatica, polypoidal choroidal vasculopathy (PCV), pre-term labor, prostate cancer, protozoan infection, psoriasis, psoriatic arthritis, pyoderma gangrenosum, reperfusion injury, respiratory syncytial virus (RSV), restenosis, retinal detachment, retinitis pigmentosa, retinopathy of prematurity (ROP), rheumatoid arthritis, septic shock, sickle-cell anemia, side effects from radiation therapy, sinusitis, skin cancer, sleep disturbance, sprain, Stargardt's disease, stomach cancer, temporal mandibular joint disease, TNF receptor associated periodic syndrome, transplant rejection, trauma, traumatic eye injury, type-2 diabetes, ulcerative colitis, and uveitis.
For this extensive menu of diseases, which have different etiologies and largely different methods of treatment, Applicant does not present any experimental data for in vivo treatment. The only method that could somehow come closer to the blue print for a method of treatment is an in vivo method of blocking complex phenotypes induced in mouse models of asthma with the antibody 14F4 ([0490]).
The art is aware of method of treatment for leukemias and solid tumor selected from prostate cancer, breast cancer, lung cancer, colorectal cancer, melanomas, bladder cancer, brain/CNS cancer, cervical cancer, oesophageal cancer, gastric cancer, head/neck cancer, kidney cancer, liver cancer, lymphomas, ovarian cancer, pancreatic cancer, and sarcomas (Ågerstam et al., U.S. Pat. No. 10,100,119; Fioretos et al., U.S. Pat. No. 9,403,906, all cited by Applicant)  as well as Hidradenitis Suppurativa (Fischer et al., U.S. Pat. No.11, 639,392). However, for the diseases shown to be treated, the structure of the antibodies used is different from the structure of the antibody claimed in the instant Application. Each antibody to be used in vivo needs to be thoroughly tested in order to assess its, potential therapeutical value and the testing methods are cumbersome  and time consuming, with no a priori knowledge of their efficacy. Such an amount of experimentation is, in view of the extremely limited guidance and working examples, considered to be undue.
Thus the only method considered enabled is the method of treating asthma with the antibodies claimed in the independent claim 1.
Conclusion
No claims are allowed.
