Office Action

§103 §112
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 . Rejections Claim Rejections - 35 USC § 112 1. 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. 2. Claims 1-14 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 the disclosed substituted compounds, does not reasonably provide enablement for all of the compounds encompassed by the instantly claimed recitations of “substituted”. 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 and/or use the invention commensurate in scope with these claims. A. The instant claims recite “substituted” without specifying the substituents. Therefore, the claims encompass all possible substituents. The instantly claimed “substituted” reads on an infinite number of compounds resulting from the potentially infinite number of substitutions which can be performed on the recited compounds. In re Wands has 8 criteria, (MPEP 2164.01(a)), as shown below. (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. It is noted that the instant claims read on all potential substitutions of the recited compounds which encompasses an infinite number of compounds (Wands factors A and B). The specification does not describe how to make all such substituents, how to add them to the claimed compounds, nor how to select those substituents from the infinite list thereof which will function as required in the instant invention (Wands factors B, F, G). It would require an infinite amount of experimentation to determine how to make all of the substituents encompassed by the instant claims and another infinite amount of experimentation to determine which of these substituted compounds would function in the instantly claimed invention as required (Wands factors B and H). Chemistry is an unpredictable art (Wands factors B and E). The ordinary skilled artisan has not imagined nor figured out how to make all of the substitutions encompassed by the instant claim of “substituted” yet (Wands factors B, C, D, E, F, G, and H). The enabling disclosure is not commensurate with the full scope of the claimed “substituted”. See Sitrick v Dreamworks, LLC (Fed Cir, 2007-1174, 2/1/2008), particularly “Before MICHEL, Chief Judge, RADER and MOORE, Circuit Judges. MOORE, Circuit Judge. 112(1) Enablement - The enablement requirement is satisfied when one skilled in the art, after reading the specification, could practice the claimed invention without undue experimentation We review the grant of summary judgment de novo. LiebeI-Flarsheim Co. v. Medrad, Inc., 481 F.3d 1371, 1377 (Fed. Cir. 2007). Summary judgment is appropriate “if the pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any, show that there is no genuine issue as to any material fact and that the moving party is entitled to judgment as a matter of law.” Fed. R. Civ. P. 56(c). Whether a claim satisfies the enablement requirement of 35 U.S.C. § 112, ¶ 1 is a question of law, reviewed de novo, based on underlying facts, which are reviewed for clear error. AK Steel Corp. v. Sollac, 344 F.3d 1234, 1238-39 (Fed. Cir. 2003). The evidentiary burden to show facts supporting a conclusion of invalidity is one of clear and convincing evidence because a patent is presumed valid. Id. The “enablement requirement is satisfied when one skilled in the art, after reading the specification, could practice the claimed invention without undue experimentation.” Id. at 1244. 112(1) Enablement - The full scope of the claimed invention must be enabled. A patentee who chooses broad claim language must make sure the broad claims are fully enabled. The full scope of the claimed invention must be enabled. See Auto. Techs. Int’l, Inc. v. BMW of N. Am., Inc., 501 F.3d 1274, 1285 (Fed. Cir. 2007). The rationale for this statutory requirement is straightforward. Enabling the full scope of each claim is “part of the quid pro quo of the patent bargain.” AK Steel, 344 F.3d at 1244. A patentee who chooses broad claim language must make sure the broad claims are fully enabled. “The scope of the claims must be less than or equal to the scope of the enablement” to “ensure[] that the public knowledge is enriched by the patent specification to a degree at least commensurate with the scope of the claims.” Nat’l Recovery Techs., Inc. v. Magnetic Separation Sys., Inc., 166 F.3d 1190, 1195-96 (Fed. Cir. 1999).” Claim Rejections - 35 USC § 103 3. 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. 4. Claims 1-14 are rejected under 35 U.S.C. 103 as being unpatentable over JP 2019-026747 Yamamoto et al., the English language translation provided by the applicant being referenced below unless otherwise noted. Yamamoto discloses a water repellant composition which contains a non-fluorinated polymer containing lauryl acrylamide, stearyl acrylamide or the other acrylamide monomers (a) of Yamamoto which fall within the scope of the instantly claimed monomers (a1) of the instant claims 1-3 and 10. This monomer is used in 30-70 wt.% based on the polymer which includes amounts of (a1) of the instant claims 1, 6, and 11. The amounts of (d) of claim 8 of Yamamoto encompass the amounts of the instantly claimed monomer (a2) of the instant claims 1 and 11. See the abstract of Yamamoto and the remainder of the document. The water repellant composition of Yamamoto is in a liquid medium containing water and the instantly claimed water soluble solvents and amounts thereof of the instant claims 1, 7-9, and 11, noting Yamamoto, paragraph [0009], [0049], [0051], and [0078]. The cyclic monomer of Yamamoto, claim 5 falls within the scope of the instant claim 4. The non-fluorine containing crosslinkable monomer of Yamamoto’s claim 4 falls within the scope of the instant claim 5. Yamamoto discloses vinyl chloride and vinylidene chloride in their polymers at their claim 7, which falls within the scope of the instantly claimed repeating unit (a2). The method of Yamamoto per se encompasses the method of the instant claim 11 with Yamamoto’s polymerization necessarily lowering the concentration of unreacted chloride monomer as it polymerizes and Yamamoto does not require any remaining unreacted chloride monomer. Yamamoto, claim 12 and their entire disclosure gives the inventions of the instant claims 12-14. Yamamoto does not require any unreacted chloride monomer which falls within the scope of the instantly claimed amounts of chloride monomer of the instant claims 1 and 10-11. Yamamoto does not disclose or exemplify the instantly claimed inventions with sufficient specificity to anticipate the instant claims. It would have been obvious to one of ordinary skill in the art prior to the instantly claimed invention to make the inventions of the instant claims 1-14 from the disclosure of Yamamoto because Yamamoto encompasses the instantly claimed inventions as discussed above and such in inventions would have been expected to give the properties of the inventions of Yamamoto, including those properties explicitly discussed by Yamamoto and those properties inherent to the inventions of Yamamoto.
