Office Action

§DP
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. DETAILED NON-FINAL ACTION This is the initial Office Action (OA), on the merits, based on the 18/794,963 application filed on August 5, 2024. Claims 1-26 were cancelled in a preliminary amendment. Claims 27-44 are pending and have been fully considered. The examined claims are directed to a apparatus. Information Disclosure Statement The Examiner has considered the information disclosure statements (IDS) submitted on 08/20/2024 (2), 12/31/2024 (3), 09/21/2025, 02/20/2026, 02/25/2026 and 09/09/2026. Please refer to the signed copy of the PTO-1449 form attached herewith. Specification The title of the invention is not descriptive since there are no method claims. Also, the title is the same or similar to an existing publication or patent and in that sense is not descriptive, if the instant claims and invention is considered different and unique compared to that publication/patent. To the extent that the claims are unique, titles should be as well. A unique title that is more clearly indicative of the invention to which the claims are directed will assist future examiners and reviewers. Therefore, a new title is required that is clearly indicative of the invention to which the claims are directed. Claim Objections Claim 31 is objected to because of the following informality: The claim recites “. . . wherein said at least one cold storage tank configured to circulate cold process water through said at least one condenser.” The verb “is” appears to me missing between ‘tank’ and ‘configured.’ Appropriate correction is required. Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the claims at issue are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); and In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13. The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/apply/applying-online/eterminal-disclaimer. Claims 27-44 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-19 of U.S. Patent No. US 12,054,402. Although the claims at issue are not identical, they are not patentably distinct from each other because the patent and application recite the same or similar limitations relating to a water harvesting system for capturing water from surrounding including a chamber, plates (structural elements) coated with at least one water capture material, a gap between adjacent structural elements (plates), at least one condenser positioned adjacent to one end of said plurality of plates (structural elements), at least one gate valve, at least one heat exchange manifold connected to, or positioned around, said plurality of structural elements (plates), at least one fan positioned adjacent to said plurality of structural elements at an end opposite to said at least one condenser, at least one vacuum pump connected to the chamber, and a water storage tank, configured to receive liquid water from the at least one condenser in the chamber. Each of the structures also have several of the same or similar additional functional features, such as the water capture material adsorbing water from said surrounding air during an adsorption phase, and desorbing water vapor during a desorption phase. Conclusion Other than the double patenting rejection, Examiner did not apply prior art to the claims. The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Kim et al. (Adsorption-based atmospheric water harvesting device for arid climates, Nature Communications, Vol. 9, Article No. 1191) demonstrates an air-cooled sorbent-based atmospheric water harvesting device using the metal−organic framework (MOF)-801 [Zr6O4(OH)4(fumarate)6] operating in an exceptionally arid climate (Abstract). Bulang (US 4,185,969) discloses a process and an apparatus for recovering water from moist gas, e.g., humid air, where the apparatus comprises fans, solar energy collectors, moisture absorber beds, and heat-accumulators that are connected by conduit means in such a manner that in a first reaction stage, e.g., at night time, moist gas, e.g., humid air, is sucked into the apparatus, is divided into two partial flows (Abstract). However, it does not appear to teach or suggest the localized structural matrix, manifold, and fan-to-condenser path recited in Claim 27. Kim et al. (US20180171604) (IDS of 08-24-2024) is in the same field of atmospheric water harvesting and typifies the baseline art of this era. It addresses moisture collection via a sorbent but appears to lack certain structural features recited in claim 27. Examiner recommends that Applicant carefully review each identified reference and all objections/rejections before responding to this office action to properly advance the case in light of the pertinent objections/rejections and the prior art. With respect to the patentability analysis, Examiner has attempted to claim map to one or more of the most suitable structures or portions of a reference. However, with respect to all OAs, Examiner notes that citations to specific pages, columns, paragraphs, lines, figures or reference numerals, in any prior art or evidentiary reference, and any interpretation of such references, should not be considered to be limiting in any way. A reference is relevant for all it contains and may be relied upon for all that it would have reasonably disclosed and/or suggested to one having ordinary skill in the art. The use of publications and patents as references is not limited to what one or more applicant/inventor/patentee describes as their own inventions or to the problems with which they are concerned. They are part of the literature of the art, relevant for all they contain. MPEP §2123. Examiner further recommends that for any substantive claim amendments made in response to this Office Action, or to otherwise advance prosecution, or for any remarks concerning support for added subject matter or claim priority, that Applicant include either a pinpoint citation to the original Specification (i.e. page and/or paragraph and/or line number and/or figure number) to indicate where Applicant is drawing support for such amendment or remarks, or a clear explanation indicating why the particular limitation is implicit or inherent to the original disclosure. Electronic Inquiries Any inquiry concerning this communication or an earlier communications from the examiner should be directed to Hayden Brewster whose telephone number is (571) 270-1065. The examiner can normally be reached M-Th 9 AM - 4 PM. Alternatively, to contact the examiner, Applicant may send a communication, via e-mail or fax. Examiner’s direct fax number is: (571) 270-2065. Examiner's official e-mail address is: "Hayden.Brewster@uspto.gov." However, since e-mail communication may not be secure, Examiner will not respond to a substantive e-mail unless Applicant’s communication is in accordance with the provisions of MPEP §502.03 & related sections that discuss the required Authorization for Internet Communication (AIC). Nonetheless, all substantive communications will be made of record in Applicant’s file. To facilitate the Internet communication authorization process, Applicant may file an appropriate letter, or may complete the USPTO SB439 fillable form available at https://www.uspto.gov/sites/default/files/documents/sb0439.pdf, preferably in advance of any substantive e-mail communication. Since one may use an electronic signature with this particular form, Applicant is encouraged to file this form via the Office’s system for electronic filing of patent correspondence (i.e., the electronic filing system (Patent Center)). Otherwise, a handwritten signature is required. In addition to Patent Center, Applicant can submit their Internet authorization request via US Postal Service, USPTO Customer Service Window, or Central Fax. Examiner can also provide a one-time oral authorization, but this will only apply to video conferencing. It is improper to request Internet Authorization via e-mail. Examiner interviews are available via telephone, in-person, and via video conferencing using a USPTO supplied web-based collaboration tool. To schedule an interview, Applicant is encouraged to use the USPTO Automated Interview Request (AIR) form available at http://www.uspto.gov/interviewpractice, or Applicant may call Examiner, if preferable. Applicant can access a general list of patent application forms at either https://www.uspto.gov/patent/forms/forms-patent-applications-filed-or-after-september-16-2012 (applications filed on or after September 16, 2012) or https://www.uspto.gov/patent/forms/forms (applications filed before September 16, 2012). Note that the language in an AIR form is not a substitute for the requirements of an AIC, where appropriate. The mere filing of an Applicant Initiated Interview Request Form (PTOL-413A) or a Letter Requesting Interview with Examiner, in EFS-Web, may not apprise Examiner of such a request in a timely manner. If attempts to reach the Examiner are unsuccessful, Applicant may reach Examiner’s supervisor, Bobby Ramdhanie at 571-270-3240. The central fax phone number for the organization where this application or proceeding is assigned is 571-273-8300. Information regarding the status of published or unpublished applications may be obtained from Patent Center. Unpublished application information in Patent Center is available to registered users.
