Office Action

§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 . Response to Arguments Applicant has argued that the prior art of record does not disclose, teach, or suggest the limitation of the vent channel comprising one or more valves and a cavity in the path of the vent channel, as required by the amendment to independent claim 1, and the Examiner agrees. Therefore, the prior art rejections of the previous Office Action have been withdrawn. Applicant’s amendment has necessitated a new grounds of rejection due to the rejoinder of previously withdrawn claims 11-20. Election/Restrictions Claim 1 is allowable. Claims 11-20, previously withdrawn from consideration as a result of a restriction requirement, require all the limitations of an allowable claim. Pursuant to the procedures set forth in MPEP § 821.04(a), the restriction requirement between inventions Groups I- III, as set forth in the Office action mailed on 04/10/2025, is hereby withdrawn and claims 11-20 are hereby rejoined and fully examined for patentability under 37 CFR 1.104. In view of the withdrawal of the restriction requirement, applicant(s) are advised that if any claim presented in a divisional application is anticipated by, or includes all the limitations of, a claim that is allowable in the present application, such claim may be subject to provisional statutory and/or nonstatutory double patenting rejections over the claims of the instant application. Once the restriction requirement is withdrawn, the provisions of 35 U.S.C. 121 are no longer applicable. See In re Ziegler, 443 F.2d 1211, 1215, 170 USPQ 129, 131-32 (CCPA 1971). See also MPEP § 804.01. Claim Objections Claim 16 is objected to because of the following informalities: It is recommended to amend “the container interior” so as to read “a container interior”. Appropriate correction is required. 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 16-20 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. Regarding claim 16, the phrase "such as" renders the claim indefinite because it is unclear whether the limitations following the phrase are part of the claimed invention. See MPEP § 2173.05(d). It is unclear if the narrower limitation “such as a vacuum flask” is a required limitation and therefore the intended scope of the claim is unclear. Regarding claim 19, the phrase "such as" renders the claim indefinite because it is unclear whether the limitations following the phrase are part of the claimed invention. See MPEP § 2173.05(d). It is unclear if the narrower limitation “such as liquid nitrogen” is a required limitation and therefore the intended scope of the claim is unclear. Regarding claim 20, the phrase "such as" renders the claim indefinite because it is unclear whether the limitations following the phrase are part of the claimed invention. See MPEP § 2173.05(d). It is unclear if the narrower limitation “such as a metal or metallic block” is a required limitation and therefore the intended scope of the claim is unclear. Dependent claims are rejected for the same reason(s) as the base claim(s) upon which they depend. Allowable Subject Matter Claims 1 and 3-15 are allowed. The following is a statement of reasons for the indication of allowable subject matter: Regarding independent claim 1, McCormick (US Patent Application 2019/0063688) in view of Kotake et al. (US Patent Application Publication 2018/0250913) provides the closest prior art, as discussed in the prior Office Action. However, the prior art of record does not fairly teach the limitation of the vent channel comprising one or more valves and a cavity in the path of the vent channel, within the claim environment. Claim 11 is directed to a shipping system comprising the bung according to claim 1 and is accordingly also allowable. Claim 16 is directed to a method of using the bung according to claim 1. Claim 16 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
