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 .
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 1-5 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 1, the recitation of the device “to generate nano hydrogen bubbles and nano ion water or alkaline electrolytic water” is confusing as to what the device generates.  The recitation of “and” followed by “or” makes it unclear as to precisely which types of water are being generated.  Applicant is suggested to more clearly define the device “configured to receive tap water and electrolyze the tap water to generate nano hydrogen bubbles with either nano ion water or alkaline electrolytic water to produce a cleaning fluid”.
Regarding claim 1, it is unclear how the “recycled water nano bubbles generation device” is used for “generating ozone nano bubbles”.  What is meant by “recycled by the system”?  Is this device configured to receive/recycle water from the washing machine?  Does the recycled water already include nano bubbles?  Or is the device configured to generate ozone nano bubbles by itself?  The structure and structural configuration is unclear.  As best understood from the original disclosure, the recycled water nano bubbles generation device is configured to receive tap water and water recycled by at least one washing machine and generate ozone nano bubbles from a mixture of the tap water and the recycled water to be supplied to the at least one washing machine.  Applicant is suggested to more clearly define the structural configuration in such manner to particularly point out and distinctly claim their invention and the structural cooperative relationship between the generation devices and the at least one washing machine.
Regarding claim 1, the recitation of at least one washing machine “capable of performing one of a plurality of wash cycles…” is indefinite because it is unclear what applicant intends.  As claimed, the wash cycles are merely intended use which may be performed by any programmable controller for a washing machine.  If applicant’s intent is to positively recite such features as structural elements of the claimed apparatus, applicant may wish to recite the at least one washing machine “programmed to perform one of a plurality of wash cycles…” so such features may be given patentable weight in the claimed apparatus.
Regarding claim 3, it is unclear what structure is being recited for a “treatment system”.  What treatment device is being used and what treatment is being performed?  Clarification and correction are required.
Claim Rejections - 35 USC § 102
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 (i.e., changing from AIA  to pre-AIA ) 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.
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.
Claim(s) 1 is/are rejected under 35 U.S.C. 102(a)(2) as being anticipated by CN 114797521 A to Chen et al. (“Chen”).
Regarding claims 1, Chen discloses a system for washing laundry comprising:
a cleaning fluid electrolytic hydrogen nano bubbles generation device for receiving tap water and electrolyzing the tap water to generate nano hydrogen bubbles and nano ion water or alkaline electrolytic water together as a cleaning fluid (note nano- bubble generator 1, electrolytic generator 2, and hydrogen generator 4);
a recycled water nano bubbles generation device for receiving tap water and water recycled by the system and generating ozone nano bubbles from a mixture of the tap water and the recycled water (note ozone generator 3 and recirculation lines leading to and from washing machine 14); and
at least one washing machine (14) capable of performing one of a plurality of wash cycles including pre-wash, main wash, and rinse (note the washing machine of Chen is fully capable of the recited intended use of performing such wash cycles);
wherein in the pre-wash or rinse, the recycled water nano bubbles generation device supplies the tap water having ozone nano bubbles to each of the at least one washing machine through a pre-wash or rinse line so that each of the at least one washing machine is configured to perform. the pre-wash or rinse (intended use, see above, the washing machine of Chen fully capable of performing such intended use); and
wherein in the main wash, the cleaning fluid electrolytic hydrogen nano bubbles generation device supplies the main solution to each of the least one washing machine through a cleaning fluid line so that each of the at least one washing machine is configured to perform the main wash (intended use, see above, the washing machine of Chen fully capable of performing such intended use).
Claim Rejections - 35 USC § 103
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 (i.e., changing from AIA  to pre-AIA ) 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.
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.
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.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary.  Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claim(s) 2-4 is/are rejected under 35 U.S.C. 103 as being unpatentable over Chen in view of US 5,493,743 to Schneider et al. (“Schneider”).
Regarding claims 2-4, Chen discloses the claimed invention including recycling water and generating ozone for washing water of a washing machine.  Chen does not discloses the filter or water treatment system as recited in claims 2-3.  Schneider teaches that it is known to provide a washing system with a recycling system having filters 22 and water treatment system 60 prior to ozone treatment of recycled water for washing machine 10 in order to remove particulates and ions that may interfere with generation of ozone (see Fig. 1 and col. 4, ll. 7-59).
Therefore, the position is taken that it would have been obvious at the time of effective filing to provide the system of Chen with the filter and water treating water softener system of Schneider to achieve the predictable results of treating recycled water prior to ozonation and resupply to a washing machine.
Claim(s) 5 is/are rejected under 35 U.S.C. 103 as being unpatentable over Chen in view of Schneider, as applied to claim 4 above, and further in view of US 2022/0316190 to Connolly et al. (“Connolly”).
Chen and Schneider, supra, disclose the claimed invention including recycling ozonated water to a washing machine.  Neither discloses electrolyzing the ozone bubbles as recited in claim 5.  However, it is old and known to provide various known techniques to recycled washing water including both electrolysis treatment and ozone treatment.  For instance, Connolly teaches a water recycling system for a washing machine, and treating the recycled water with filtering, electrolysis treatment, and ozone treatment (see Schneider at ¶ [0081]-[0084]).
Therefore, the position is taken that it would have been obvious at the time of effective filing to provide the combination of Chen and Schneider with electrolysis treatment and ozone treatment, such as that taught in Connolly, to achieve the same and predictable results of treating recycled washing water for reuse.

Q
In responding to the Office's prior art rejections, Applicant here mainly justifies the patentability of the independent claim 1.  As the Examiner will appreciate, should the independent claim be patentable over the prior art, narrower dependent claims would also necessarily be patentable. Accordingly, Applicant does not separately discuss the patentability of each dependent claim, although it reserves the right to do so at a later time if necessary.
Chen teaches A micro-nano hydrogen bubble water generation system, as shown in Figure [, includes a micro-nano bubble water generator 1, an electrolysis module 2, an ozone generation module 3, a hydrogen treatment module 4, a water storage module 5, a sensor module 6, a valve module 7, a piping module 8, a water pump module 9, and a control module I 1. It can also be connected to a washing wastewater treatment system 10 and a washing system 14, forming a
complete system for the preparation of washing water, item washing, and washing wastewater treatment. (see Chen, paragraph [0041]).
Chen further teaches The upper part of the water storage module 5 is equipped with a hydrogen treatment module 4, which dilutes the hydrogen gas escaping from the water storage module 5 by 500 to 1000 times, reducing the hydrogen concentration to a safe level (<0.1%) before releasing it, thus preventing the hydrogen content in the water storage module 5 from becoming too high and causing an explosion. The bottom of the water storage module 5 is equipped with a sensor module 6, which includes a temperature sensor, an ORP sensor, a pH sensor, and a liquid level sensor, each of which is signal-connected to the control module 11. These sensors measure the water temperature, ORP, pH, and liquid level in the water storage module 5 and send the collected data to the control module 11. (see Chen, paragraph [0042]).
Accordingly, contrary to the features recited in the amendment claim 1, Chen merely teaches the inclusion of recycling water and generating ozone for washing water of a washing machine.
However, in the present application, the perforated basket of the washing machine 7 rotates to remove dirty water from the washed clothes. The dirty water is drained the washing machine 7 to a pre-wash (or rinse) water filter 1 through a pre-wash (or rinse) recycled water line 10. Water is filtered by the pre-wash (or rinse) water filter 1 to remove dirt and then the filtered water flows to a pre-wash (or rinse) water treatment system 2 for treatment. The treatment includes biological, chemical and physical treatment methods. The treated water (i.e., recycled water) flows to the recycled water nano bubbles generating device 3 which activates to generate ozone nano bubbles in the recycled water. The perforated basket of the washing machine 7 rotates to remove dirty water from the washed clothes. The dirty water flows to a cleaning fluid filter 4 through a cleaning fluid recycled line 11. The cleaning fluid filter 4 removes solid particles from the dirty water. The filtered water flows to a dirty cleaning fluid ozone nano bubbles treatment device 5. The dirty cleaning fluid ozone nanometer bubbles treatment device 5 used with electrolysis device as an advance oxidation system for washed water treatment. This advanced oxidation treatment can purify dirty water, decrease chemical oxygen demand (COD), and increase oxidation power.
Accordingly, Chen fails to teach a pre-wash or rinse water filter wherein after the pre-wash or rinse has been performed, water flows through a pre-wash or rinse recycled water line into the pre-wash or rinse water filter and the pre-wash or rinse water filter is configured to filter the water;a pre-wash or rinse water treatment system connected between the pre-wash or rinse water filter and the recycled water nano bubbles generation device, the pre-wash or rinse water treatment system is configured to treat the filtered water from the pre-wash or rinse water filter and send the treated water to the recycled water nano bubbles generation device.
At least for the foregoing reasons, independent claim 1, as amended, is patentable over Chen, under 35 U.S.C. §102b.
Schneider discloses that after a wash cycle is completed, the spent wash water in sump 18 is pumped by a sump pump 20 through
a suitable bag
o
r screen filter 22 into a holding tank 21.
[Emphasis added]. Holding tank 21 has weir 25 which overflows to drain 13 to avoid any spillage if holding tank 21 becomes too full.
Water from holding tank 21 is transferred by pump 27 through particulate filter 29 into storage tank 24.
[Emphasis added]. A supply of fresh water may also be added from a make-up water supply line 26 to storage tank 24 or sump 18 by means of a make-up water valve 28. An optional water softener 60 may be added if the indigenous water supply is subject to hardness. The water softener removes ions (Fe, Mn, Mg, Ca) that interfere with the generation of ozone, as they will oxidize and use up some of ozone in the system making it difficult to maintain an active residual level of ozone. (see Schneider, col.4, lines 27-43).
Schneider further discloses that pump 30 draws water from storage tank 24 and pumps it
through particulate or p
o
lish filter 32.
[Emphasis added]. The filters in the system starting with filter 22 function as a tiered filtration system, that is the size of particulate material filtered out of the recycled water gradually becomes smaller. This prevents the initial filter 22 from becoming clogged as it does not try to collect all particulate. (see Schneider, col.4, lines 44-50).
Therefore, Schneider teaches
a suitable ba

f

However, in the present application, the perforated basket of the washing machine 7 rotates to remove dirty water from the washed clothes. The dirty water is drained the washing machine 7 to a pre-wash (or rinse) water filter 1 through a pre-wash (or rinse) recycled water line
10. Water is filtered by the pre-wash (or rinse) water filter 1 to remove dirt and then the filtered water flows to a pre-wash (or rinse) water treatment system 2 for treatment. The treatment includes biological, chemical and physical treatment methods. The treated water (i.e., recycled water) flows to the recycled water nano bubbles generating device 3 which activates to generate ozone nano bubbles in the recycled water.
Accordingly, this application specifically introduces a biochemical-physical method that combines biodegradation, chemical reactions, and physical actions, which can effectively remove organic pollutants, bacteria, viruses, and other difficult-to-remove contaminants from water. The biochemical-physical method employed in this application not only removes solid pollutants that can be eliminated by traditional physical filtration, but also removes harmful microorganisms, dissolved organic matter, and inorganic substances in the water. Compared to the method in the reference document, which only uses physical filtration, the present invention provides a more efficient wastewater treatment solution that can more comprehensively purify water quality.
ls to teach a pre-wash or rinse water treatment system connectedbetween the pre-wash or rinse water filter and the recycled water nano bubbles generation device, the pre-wash or rinse water treatment system is configured to treat the filtered water from the pre-wash or rinse water filter and send the treated water to the recycled water nano bubbles generation device.
Schneider discloses a reclaimed water treatment system, which mainly includes filters such as bag filters, screen filters, particle filters, and particle or polishing filters, used for the initial solid particle filtration of reclaimed water. These filters are primarily designed to remove large particulate contaminants in the water, such as sand, dust, and other solid particles, thereby improving water quality. From  simple physical filtration to the comprehensive use of biochemical-physical methods, this application offers significant advantages in improving water quality, reducing pollution, and enhancing water recovery efficiency. Through these improvements, the present invention not only provides a more efficient and environmentally friendly water treatment method at a technical level but also has important economic and social benefits.
Withdrawal of the 35 U.S.C. § 103 rejection to claim 1 is respectfully requested.
Accordingly, claims 4-5, which depend from  now allowable amended claim    1, are patentable as well.
Accordingly, claims 2 and 3 has been canceled, which makes the rejections to claims 2 and
3 moot.
Accordingly, Applicant submits that the rejection under 35 U.S.C. 103 has been overcome, and respectfully requests consideration and withdrawal of outstanding rejection and an indication that the claims are allowable at the Examiner's earliest convenience.
