Office Action

§102 §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 . In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. Election/Restrictions Applicant’s election without traverse of Group I in the reply filed on 29 March 2026 is acknowledged. Claims 13-18 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected species, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on 29 March 2026 Claim Objections Claims are objected to because of the following informalities: Cl.2 and 9: “the tray defining” is believed to be in error for --the tray to define-- Cl.3 and 10: “extend across” is believed to be in error for --extends across-- Cl.5: “between film” is believed to be in error for --between the film-- Cl.6: “film joined” is believed to be in error for --film is joined-- Cl.8: “housing configured” is believed to be in error for --housing is configured-- 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 2-3, 5, and 8-12 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 pre-AIA the applicant regards as the invention. Regarding Claim 2, the recitation(s) “the first enclosure includes a tray” renders the claim indefinite because it is unclear whether the tray is part of first enclosure or a separate element. Similarly, claim 8, recites “the first enclosure includes an inner wall and a tray along the inner wall”, which is unclear whether the tray, the first enclosure, and the inner wall, are all separate elements or whether one or more of them are subcomponents of the other. Regarding claim 5, “between film” is unclear because “between” requires two elements (i.e. between A and B) and only one (film) is recited. Dependent Claims 3 and 9-12 are also rejected for relying on at least one rejected claim above. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale or otherwise available to the public before the effective filing date of the claimed invention. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
