Office Action

§101 §112
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 Objections Claims 23-28 are objected to because of the following informalities: The claims refer to “A film according to claim 22”, which should be “The film according to claim 22” because the film is previously recited. Appropriate correction is required. Claim Rejections - 35 USC § 101 35 U.S.C. 101 reads as follows: Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title. Claim 28 is rejected under 35 U.S.C. 101 because the claimed recitation of a use, without setting forth any steps involved in the process, results in an improper definition of a process, i.e., results in a claim which is not a proper process claim under 35 U.S.C. 101. See for example Ex parte Dunki, 153 USPQ 678 (Bd.App. 1967) and Clinical Products, Ltd. v. Brenner, 255 F. Supp. 131, 149 USPQ 475 (D.D.C. 1966). Claim Rejections - 35 USC § 112 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 15-28 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. In claim 1, “determined as described in an experimental part” and ”determined as described in the experimental part” are recited in the fourth and last line. It is unclear whether applicant intends to claim can property can be determined by any experiment, the specific experiment part of the instant disclosure, or something other. It is recommended that the limitations be deleted. Claim 28 provides for the use of a film, but, since the claim does not set forth any steps involved in the method/process, it is unclear what method/process applicant is intending to encompass. A claim is indefinite where it merely recites a use without any active, positive steps delimiting how this use is actually practiced. Allowable Subject Matter Note that the claims are not rejected over prior art. The closes prior art is: WO 2021/013552, WO 2016/083208, and US 2014/019277, which do not teach the claimed properties of the copolymer as outlined in the ISR. US 2010/00299827 and US 2019/0077946 disclose multimodal polyethylene copolymers having low and high crystalline fractions, however is silent on the claimed properties of the ratio of molecular weights and claimed TREF profile. Copending application 19/118,549 claims similar claims, however is later filed.
