OFFICE ACTION:
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’s response is acknowledged and appreciated.  The amendment of claim 3 has overcome the objection.  Applicant’s Terminal Disclaimer filed 1/30/2025 has been disapproved and therefore the following double patenting rejection is maintained.
Double Patenting
The non-statutory 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 non-statutory double patenting rejection is appropriate where the conflicting claims 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); 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 non-statutory 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 non-statutory 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.
Claim 1 is rejected on the ground of non-statutory double patenting as being unpatentable over claim 1 of U.S. Patent No. 11,760,493.  Although the claims at issue are not identical, they are not patentably distinct from each other because the only difference between the instant claim 1 and the conflicting claim 1 is at line 11 of the instant claim 1 stating “the second conduit inlet is arranged separate from the first conduit outlet and wherein the first conduit inlet is arranged separate from the second conduit outlet”.  Note that although the language is not identical, at line 19 of claim 1 of the conflicting patent, the language “each of the first conduit, the second conduit, the first duct and the second duct are separate from one another” encompasses the instant claim 1 language since it logically teaches that the first and second conduits as well as their respective inlets and outlets, are separate from one another.
Allowable Subject Matter
Claims 2-13 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
The following is a statement of reasons for the indication of allowable subject matter:  With respect to claim 2, the closest prior at fails to teach or make obvious, including all the limitations of claim 2, a first guide element arranged at the second conduit outlet in the second duct for separating the air stream coming from the second conduit from the air stream in the second conduit at least on a part of a length of the second duct.  Note that it is assumed that claim 3 was intended to depend from claim 2 as it pertains to the indication of allowable subject matter for claims 3, 7, 10, 11 and 13.
Summary/Conclusion
Claim 1 is rejected and claims 2-13 are objected to.
THIS ACTION IS MADE FINAL.  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 extension fee 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.

APPLICANT REBUTTAL: Remarks
A Petition for a One (1) month Extension of Time pursuant to relevant portions of 37 CFR
X1
.136 and the r
eq
uired fee are filed concurrently with this paper.
Status of Claims
Claim 1-13 are pending. Claim 3 has been objected to due to informalities, and claim 1 has been rejected under the doctrine of obviousness-type double patenting based on claim 1 of commonly owned U.S. Patent No. 11,760,493. Applicant respectfully requests reconsideration based on the amended claim, attached Terminal Disclaimer, and the following discussion.
Applicant gratefully acknowledges the allowability of all pending claims over the prior art of record.
Claim Objection
Claim 3 has been amended to depend from pending claim 2. Withdrawal of this rejection and reconsideration are respectfully requested.
Double Patenting
A properly executed Terminal Disclaimer is filed concurrently with this paper under relevant portions of 35 USC § 1.321, thereby obviating the above-noted rejection. Withdrawal and reconsideration is respectfully requested.
Conclusion

NEXT OFFICE ACTION: 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’s response dated 3/26/2025 is acknowledged and appreciated.  The Terminal Disclaimer submitted 2/24/2025 is now approved and the application is allowable as follows.
Terminal Disclaimer
The terminal disclaimer filed on 2/24/2025 disclaiming the terminal portion of any patent granted on this application which would extend beyond the expiration date of patent 11,760,493 has been reviewed and is accepted.  The terminal disclaimer has been recorded.
Allowable Subject Matter
Claims 1-13 are allowed.
The following is an examiner’s statement of reasons for allowance: The closest prior art fails to teach or make obvious, that each of the first conduit, the second conduit, the first duct and the second duct are separate from one another and that the first duct and the second duct each carry humidified air downstream the first conduit inlet and downstream the second conduit inlet.
Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee.  Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.”
