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 .
Information Disclosure Statement
1.	The information disclosure statements (IDS) submitted on 10/25/2023 has been considered by the examiner.
Claim Rejections - 35 USC § 101
2.	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.
3.	Claims 22-38 are rejected under 35 U.S.C. 101 because the claimed invention is directed to a judicial exception (i.e., a law of nature, a natural phenomenon, or an abstract idea) without significantly more.
Claims 22, 25, 28, and 35 are directed to  “comparing”, “detecting” and/or “determining” steps.  These are considered mental steps and thus represent an abstract idea as these steps can be done by a user by simply observing the machine.
After the “determining” step takes place then no action is taken based on the “determining”.  Maintaining a current state and/or outputting and performing an operation “based on” the detected information is not a particular application but merely insignificant extra solution activity, and just applying it, respectively.  The claims are directed to linking the abstract idea to a field of endeavor and not a particular practical application.
The claims do not recite any elements which are significantly more than the abstract idea, as the combination of a drying and washing unit seems to be routine and conventional.
As such, the claims are not considered to be proper under 35 USC 101.  Any amendment must be commensurate with the corresponding specification.
Regarding dependent claims 23-24, 26-27, 29-34, and 36-38, they do not overcome the 101 rejections because they do not contribute significantly more beyond the abstract idea.
Claim Rejections - 35 USC § 103
4.	The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
5.	The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
6.	Claims 1 and 39 are rejected under 35 U.S.C. 103 as being unpatentable over Scheible et al. (PG Pub U.S 2020/0370226) and further in view of Grunert (PG Pub U.S 2010/0101606).
7.	Regarding claim 1, Scheible teaches a method for controlling a laundry management apparatus (figs 1-2 and abstract) including a washing unit (102) and a drying unit (104) (para 0021), the method comprising performing a washing operation of the washing unit (para 0023); performing a hygienic operation of the drying unit (para 0033); and terminating the hygienic operation of the drying unit and the washing operation of the washing unit (para 0035).
8.	Scheible fails to teach wherein the hygienic operation comprises automatically washing and drying a condenser of the drying unit.  However, Grunert teaches a washer/dryer combo operation method wherein it is known to wash the condenser (abstract and claim 16) in order to effectively remove deposits and lint from the condenser.  Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Scheible such that the hygienic operation comprises automatically washing and drying a condenser of the drying unit in order to effectively remove deposits and lint from the condenser.
9.	Regarding the limitation of performing the hygienic operation of the drying unit simultaneously with the washing operation of the washing unit and terminating the hygienic operation on or before the completion time of the washing operation, it would be obvious to one of ordinary skill in the art to operate them simultaneously and terminate the hygienic operation on or before the completion of the washing operation in order to save time and allow for condenser to be prepared prior to the next laundry cycle.
10.	Regarding claim 39, the present combination of Scheible and Grunert teaches setting a hygiene management mode of the drying unit (abstract of Grunert); and maintaining the drying unit in the hygiene management mode until receiving an external signal for releasing the hygiene management mode after the hygiene management mode is set (para 0038-0039 of Grunert).
11.	Claim 21 is rejected under 35 U.S.C. 103 as being unpatentable over Scheible et al. (PG Pub U.S 2020/0370226) and Grunert (PG Pub U.S 2010/0101606) and further in view of Park et al. (PG Pub U.S 2008/0053164).
12.	Regarding claim 21, the present combination of Scheible and Grunert teaches the drum of the dryer being configured to receive laundry (abstract and para 0035 of Scheibler), but fails to teach sterilizing and drying an inside of a drum of the drying unit.  However, Park also teaches cleaning a drying unit (abstract) wherein it is known to sterilize and dry an inside of a drying drum (para 0070) in order to prevent contamination and achieve clean laundry.  Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention for the present combination of Scheible and Grunert to include sterilizing and drying an inside of a drum of the drying unit as taught by Park in order to prevent contamination and achieve clean laundry.
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.

APPLICANT REBUTTAL: REMARKS
In response to the Office Action of June 5, 2024, Applicant asks that the application be allowed in view of the amendments above and the following remarks. Claims 1 and 21-39 are pending, with claim 1 being independent. Claim 1 has been amended, claims 2-20 have been canceled without prejudice or disclaimer of subject matter, and claims 2 1-39 have been added. Support for the amendments and new claims can be found throughout the specification as filed, for example, at page 12, lines 1-13. No new matter has been introduced.
Stat
utorv
Double
Patenting
Claims 1-20 were rejected under 35 U.S.C. @ 101 over claims 1-20 of U.S. Patent No.
11,828,019 ("Park"). In an effort to advance prosecution, Applicant has amended claim 1 as set forth above to obviate the statutory double patenting rejection. Specifically, claim 1 has been amended to recite "automatically washing and drying a condenser of the drying unit while performing the washing operation of the washing unit" and "terminating the hygienic operation of the drying unit on or before a completion time of the washing operation of the washing unit." Park does not recite at least these features of amended claim 1.
Accordingly, Applicant submits that amended independent claim 1 is in condition for allowance.
New
Claims
New claims 21-39 depend from amended independent claim 1. Therefore, Applicant respectfully submits that claims 21-39 are allowable for the reason of that dependency and the reasons discussed above with respect to claim 1.
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 .
Continued Examination Under 37 CFR 1.114
A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection.  Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.  Applicant's submission filed on 5/28/2025 has been entered.
Examiner’s Amendment
An examiner’s amendment to the record appears below. Should the changes and/or additions be unacceptable to applicant, an amendment may be filed as provided by 37 CFR 1.312. To ensure consideration of such an amendment, it MUST be submitted no later than the payment of the issue fee.
Authorization for this examiner’s amendment was given in an interview with Minseung Ahn on July 10, 2025.
The application has been amended as follows:
Claim 1: (Currently Amended) A method for controlling a laundry management apparatus including a washer and a dryer, the method comprising: performing a washing operation by the washer; while the washing operation is performed by the washer, performing a hygienic operation by the dryer before performing a drying operation by the dryer, wherein the hygienic operation comprises washing and drying a condenser of the dryer; and synchronizing the washing operation of the washer and the hygienic operation of the dryer such that the hygienic operation is completed on or before a completion time of the washing operationwherein performing the hygienic operation comprises: based on a first operation time of the washing operation being less than a second operation time of the hygienic operation, resetting the first operation time to be greater than or equal to the second operation time or resetting the second operation time to be less than or equal to the first operation time to thereby terminate the hygienic operation of the dryer on or before terminating the washing operation of the washer.
Claim 22: (Canceled)
Claim 23: (Currently Amended) The method of claim 1, wherein the washing operation of the washer is performed according to the first operation time that is reset to be greater than or equal to the second operation time.
Reasons for Allowance
Claims 1, 21, 23-27, 29-30, and 32-39 are allowed.
The following is an examiner’s statement of reasons for allowance:
The closest prior art of record is Scheible et al. (PG Pub U.S 2020/0370226) and Grunert (PG Pub U.S 2010/0101606).
Scheible teaches a method for controlling a laundry management apparatus including a washing unit and a drying unit, the method comprising performing a washing operation of the washing unit; performing a hygienic operation of the drying unit; and terminating the hygienic operation of the drying unit and the washing operation of the washing unit.
Scheible fails to teach wherein performing the hygienic operation comprises: based on a first operation time of the washing operation being less than a second operation time of the hygienic operation, resetting the first operation time to be greater than or equal to the second operation time or resetting the second operation time to be less than or equal to the first operation time to thereby terminate the hygienic operation of the dryer on or before terminating the washing operation of the washer.
Grunert teaches a washer/dryer combo operation method wherein it is known to wash the condenser.
Grunert fails to teach wherein performing the hygienic operation comprises: based on a first operation time of the washing operation being less than a second operation time of the hygienic operation, resetting the first operation time to be greater than or equal to the second operation time or resetting the second operation time to be less than or equal to the first operation time to thereby terminate the hygienic operation of the dryer on or before terminating the washing operation of the washer.
Regarding the limitation of performing the hygienic operation of the drying unit simultaneously with the washing operation of the washing unit and terminating the hygienic operation on or before the completion time of the washing operation, it would be obvious to one of ordinary skill in the art to operate them simultaneously and terminate the hygienic operation on or before the completion of the washing operation in order to save time and allow for condenser to be prepared prior to the next laundry cycle.
Thus, the prior art of record does not fairly teach or suggest a method for controlling a laundry management apparatus as in the context of claim 1.
