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 .
Claim Rejections - 35 USC § 112a
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, 3-4, 11, and 14-17 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.
The Court has indicated in Amgen Inc vs Sanofi ( 2017-1480, Fed Cir, 2017) that the disclosure of a well characterized antigen is insufficient for an adequate written description of the antibody that binds the antigen. The Court stated that “an adequate written description must contain enough information about the actual makeup of the claim products – 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 material,” which may be present in “function “terminology “when the art has established a correlation between structure and function” (page 17, 1st paragraph). The Court went on to indicate that knowledge of the chemical structure of an antigen does not tell you anything about the structure of the antibody (Id).
The guidelines for the Examination of Patent Applications Under the 35 U.S.C. 112, § 1 "Written Description" Requirement make clear that if a claimed genus does not show actual reduction to practice for a representative number of species, then the Requirement may be alternatively met by reduction to drawings, or by disclosure of relevant, identifying characteristics, i.e., structure or other physical and or chemical properties, by functional characteristics coupled with a known or disclosed correlation between function and structure, or by a combination of such identifying characteristics, sufficient to show the Applicant was in possession of the genus (Federal Register, Vol. 66, No. 4, pages 1099-1111, Fri. January 5, 2001, see especially page 1106 column 3).
The specification does not provide adequate written description of the claimed invention. The legal standard for sufficiency of a patent's (or a specification's) written description is whether that description "reasonably conveys to the artisan that the inventor had possession at that time of the. . .claimed subject matter", Vas-Cath, Inc. V. Mahurkar, 19 USPQ2d 1111 (Fed. Cir. 1991). In the instant case, the specification does not convey to the artisan that the Applicant had possession at the time of invention of the claimed invention, the genus of antibodies and anything else that bind to MDA5 and having a MW of 60 kDa. The genus of antibodies and anything else are claimed by function, the ability to bind to MDA5 and having a MW of 60 kDa. The specification does not disclose sufficient members of the genus to show possession of the genus. The Federal Circuit addressed the application of the written description requirement to DNA-related inventions in University of California v. Eli Lilly and Co., 119 F.3d 1559, 43 USPQ2d 1398 (Fed. Cir. 1997). The court stated that “[a] written description of an invention involving a chemical genus, like a description of a chemical species, requires a precise definition, such as by structure, formula, [or] chemical name, of the claimed subject matter sufficient to distinguish it from other materials.” Id. At 1567, 43 USPQ2d at 1405. The court concluded that “naming a type of material generally known to exist, in the absence of knowledge as to what that material consists of, is not a description of that material.” Id.
The Federal Circuit clarified that a molecule can be adequately described without disclosing its complete structure. See Enzo Biochem, Inc. V. Gen-Probe Inc., 296 F.3d 1316, 63 USPQ2d 1609 (Fed. Cir. 2002). The Enzo court adopted the standard that the written description requirement can be met by “show[ing] that an invention is complete by disclosure of sufficiently detailed, relevant identifying characteristics ....i.e., complete or partial structure, other physical and/or chemical properties, functional characteristics when coupled with a known or disclosed correlation between function and structure, or some combination of such characteristics. “ Id. At 1324, 63 USPQ2d at 1613 (emphasis omitted, bracketed material in original).
Furthermore The Board in Ex Parte Kubin found that the written description of 35 USC 112 was not met, stating that
Without a correlation between structure and function, the claim does little more than define the claimed invention by function. That is not sufficient to satisfy the written description requirement. See Eli Lilly, 119 F.3d at 1568, 43 USPQ2d at 1406 (“definition by function … does not suffice to define the genus because it is only an indication of what the gene does, rather than what it is”).
The Board in Ex Parte Kubin further stated on page 16 that
Possession may not be shown by merely describing how to obtain possession of members of the claimed genus or how to identify their common structural features. See University of Rochester, 358 F.3d at 927, 69 USPQ2d at 1895.
The court in In re Alonso (Fed. Cir. 2008) citing In re Enzo, Enzo, 323 F.3d at 969 stated that
[F]or purposes of satisfying the written description requirement, it is not enough merely to disclose a method of making and identifying compounds capable of being used to practice the claimed invention.
In this case, the specification does not appear to describe the genus of antibodies and anything else that bind MDA5 having 65kDa MW and thus does not satisfy either the Lilly nor Enzo standards. There are insufficient structural features common to all members of the genus of binding molecules. The Board in Kubin indicated that possession may not be shown by merely describing how to obtain possession of members of the claimed genus. However, the specification does not disclose sufficient information on the structural function relationship to identify the claimed genus of binding molecules. One of ordinary skill in the art would not be able to identify the broad claimed genus of binding molecules.
For new claims 15-17 and all the other claims that have amended in the sequence the antibody binds to, this does not describe the antibody because you still have to screen for the antibody and as pointed out above, this does not show possession.
Thus, the specification does not provide an adequate written description of the genus of binding molecules that is required to practice the claimed invention. Since the disclosure fails to provide sufficient relevant identifying characteristics, and because the genus is highly variant, one of skill in the art would reasonably conclude that the disclosure fails to provide a representative number of species to describe the genus as broadly claimed.
Applicant argues examiner does not explain the rational for the method not having written description, and the examiner does not explain the rational for rejecting the kit as it is not drawn to a genus.
Applicant’s arguments have been fully considered and not found persuasive.
For new claims 15-17 and all the other claims that have amended to include the sequence the antibody binds to, this does not describe the antibody because you still have to screen for the antibody and as pointed out above, this does not show possession.
Both the method and the kit require the antibody and applicant has not shown how to recognize the antibodies without screening for them.
Allowable Subject Matter
Claims 8 and 10 are allowed.
Claims 5 and 7 are 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.
The prior art does not teach or make obvious the CDRs of the antibodies in claims 5, 7-8, and 10.
Citation of closest prior art: Kuwana et al. (USPGPUB 20110165600).
Kuwana et al. claim 1 teaches a kit for diagnosing dermatomyositis by detecting MDA5 but does not make obvious the specific these specific antibodies and detecting the 60kDa fragment.
