Office Action

§103 §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 . Priority Acknowledgment is made of applicant’s claim for foreign priority under 35 U.S.C. 119 (a)-(d). The certified copy has been filed in parent Application No. EP19189871.7, filed on 8/2/2019. Specification The abstract of the disclosure is objected to because lines 4-5 are directed to the purported merits of the invention. A corrected abstract of the disclosure is required and must be presented on a separate sheet, apart from any other text. See MPEP § 608.01(b). Applicant is reminded of the proper language and format for an abstract of the disclosure. The abstract should be in narrative form and generally limited to a single paragraph on a separate sheet within the range of 50 to 150 words in length. The abstract should describe the disclosure sufficiently to assist readers in deciding whether there is a need for consulting the full patent text for details. The language should be clear and concise and should not repeat information given in the title. It should avoid using phrases which can be implied, such as, “The disclosure concerns,” “The disclosure defined by this invention,” “The disclosure describes,”, “The invention relates to” etc. In addition, the form and legal phraseology often used in patent claims, such as “means” and “said,” should be avoided. Claim Objections Claim 11 is objected to because of the following informalities: The limitation “absorbance peaks” should be peak to maintain proper grammar. 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 4-6,7,11,13,15-18 and 22 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. Claim 4 has the limitation “a plurality of emitter pairs” which is unclear. Specifically, it is unclear if this element is the same/different from the previously introduced “one or more capacitive emitter pairs”, as recited in claim 1. Claim 4 has the limitation “the emitters” which is unclear. Specifically, it is unclear if this element is the same/different from the previously introduced “one or more capacitive emitter pairs”, as recited in claim 1 or “a plurality of emitter pairs” in claim 4. Claim 5 recites the limitation "the device generator" in line 3. There is insufficient antecedent basis for this limitation in the claim. Claim 6 has the limitation “the plurality of emitter pairs” which is unclear. Specifically, it is unclear if this element is the same/different from the previously introduced “one or more capacitive emitter pairs”, as recited in claim 1. The limitation of “one or more capacitive emitter pairs” can be interpreted as having one pair, so it is unclear what the limitation in claim 6 is referring to. Claim 7 has the phrase “preferably” which renders the claim indefinite because it is unclear whether the limitation(s) following the phrase are part of the claimed invention. See MPEP § 2173.05(d). A broad range or limitation together with a narrow range or limitation that falls within the broad range or limitation (in the same claim) may be considered indefinite if the resulting claim does not clearly set forth the metes and bounds of the patent protection desired. See MPEP § 2173.05(c). In the present instance, claim 7 recites the broad recitation “distance of less than 10mm”, and the claim also recites “distance of less than 6 mm” which is the narrower statement of the range/limitation. The claim(s) are considered indefinite because there is a question or doubt as to whether the feature introduced by such narrower language is (a) merely exemplary of the remainder of the claim, and therefore not required, or (b) a required feature of the claims. Claim 11 has the phrase “preferably” which renders the claim indefinite because it is unclear whether the limitation(s) following the phrase are part of the claimed invention. See MPEP § 2173.05(d). Claim 13 has the phrase “preferably” which renders the claim indefinite because it is unclear whether the limitation(s) following the phrase are part of the claimed invention. See MPEP § 2173.05(d). A broad range or limitation together with a narrow range or limitation that falls within the broad range or limitation (in the same claim) may be considered indefinite if the resulting claim does not clearly set forth the metes and bounds of the patent protection desired. See MPEP § 2173.05(c). In the present instance, claim 13 recites the broad recitation “frequency between about 100 Hz and 1,000,00 Hz”, and the claim also recites “between 500 to 10,000 Hz” which is the narrower statement of the range/limitation. The claim(s) are considered indefinite because there is a question or doubt as to whether the feature introduced by such narrower language is (a) merely exemplary of the remainder of the claim, and therefore not required, or (b) a required feature of the claims. A broad range or limitation together with a narrow range or limitation that falls within the broad range or limitation (in the same claim) may be considered indefinite if the resulting claim does not clearly set forth the metes and bounds of the patent protection desired. See MPEP § 2173.05(c). In the present instance, claim 13 recites the broad recitation “frequency between about 1 Hz and 1,000 Hz”, and the claim also recites “between 10 and 100 Hz” which is the narrower statement of the range/limitation. The claim(s) are considered indefinite because there is a question or doubt as to whether the feature introduced by such narrower language is (a) merely exemplary of the remainder of the claim, and therefore not required, or (b) a required feature of the claims. Claim 15 recites the limitation "the step of measuring conductivity…" in lines 1-2. There is insufficient antecedent basis for this limitation in the claim. Claim 14 has no step of measuring conductivity, therefore there is no basis for it in the claim. Claim 16 recites the limitation "the step of determining…" in lines 1-2. There is insufficient antecedent basis for this limitation in the claim. Claim 14 has no step of determining, therefore there is no basis for it in the claim. Claim 16 has the phrase “preferably” which renders the claim indefinite because it is unclear whether the limitation(s) following the phrase are part of the claimed invention. See MPEP § 2173.05(d). Claim 17 recites the limitation "the determination step…" in lines 1-2. There is insufficient antecedent basis for this limitation in the claim. Claim 14 has no determination step, therefore there is no basis for it in the claim. Claim 17 recites the limitation "the step of real-time monitoring…" in lines 1-2. There is insufficient antecedent basis for this limitation in the claim. Claim 14 has no step of real-time monitoring, therefore there is no basis for it in the claim. Claim 18 is also rejected as being dependent from claim 17. Claim 22 has the phrase “preferably” which renders the claim indefinite because it is unclear whether the limitation(s) following the phrase are part of the claimed invention. See MPEP § 2173.05(d). A broad range or limitation together with a narrow range or limitation that falls within the broad range or limitation (in the same claim) may be considered indefinite if the resulting claim does not clearly set forth the metes and bounds of the patent protection desired. See MPEP § 2173.05(c). In the present instance, claim 22 recites the broad recitation “distance less than 1 0mm”, and the claim also recites “less than 6 mm” which is the narrower statement of the range/limitation. The claim(s) are considered indefinite because there is a question or doubt as to whether the feature introduced by such narrower language is (a) merely exemplary of the remainder of the claim, and therefore not required, or (b) a required feature of the claims. 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. Claim(s) 1-5,14,19 and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Zongyi (CN101473951A) in view of Chew et al (US 10,858,268). With regards to claim 1, Zongyi discloses a system for treating a liquid beverage using an electromagnetic field comprising alternating current (AC) and direct current (DC) components (apparatus for making a negative potential antioxidant health-care tea beverage having a power supply that rectifies an AC 220V to 150 DC, Title, Fig. 1), a power supply for supplying power to the device (source of the AC 220V, Fig. 1), a treatment chamber containing a treatment liquid beverage in a static state (electrolytic cell body 1 made of ABS plastic that holds a liquid, Fig. 1), one or more capacitive emitter pairs arranged in a predetermined pattern and placed to be in direct contact with the treatment liquid beverage (an anode plate 2 and cathode plate 4 in direct contact with the liquid inside of electrolytic cell body 1 for treatment , Fig. 1), wherein each two adjacent capacitive emitters are spaced at a predefined distance and respectively electrically coupled with first and second output terminals of the device (anode plate 2 and cathode plate 4 are each connected by wiring to power supply 5, Fig. 1), wherein current is provided in the treatment liquid beverage to produce a negative oxidation reduction potential (ORP) shift in the treatment liquid beverage (rectified 150 V DC signal is applied to anode plate 2 and cathode plate 4 in order to produce water that has a negative ORP of -800mv, page 1, lines 36-38) whose pH substantially remains constant (slightly alkaline PH of 8.5 is produced by the rectified 150 V DC signal to the anode plate 2 and cathode plate 4, page 1, lines 43-46). Zongyi does not disclose a device for generating a DC biased time-varying frequency pulsating electromagnetic wave comprising a biased DC component, wherein the device is configured to apply the DC biased time-varying frequency pulsating electromagnetic wave to the treatment liquid beverage to generate a pulsating capacitive field having a field strength between the capacitive emitters.

Before the effective filing date of the claimed invention, it would have been obvious to one of ordinary skill in the art, having the teachings of Zongyi and Chew et al before him or her, to modify the power supply of Zongyi to include the AC wave generator and DC biasing unit of Chew et al because the combination allows for an economical and convenient power supply for a treating a liquid. With regards to claim 2, Zongyi discloses wherein the currents are provided to energize the treatment beverage such that one or more treatment effects are induced in the treatment liquid beverage (rectified 150V DC signal produced by power supply 5 are supplied to anode plate 2 and cathode plate 4 to treat the liquid to provide a negative potential and anti-oxidation to the liquid, page 2, lines 15-17). With regards to claim 3, Zongyi discloses wherein the treatment effects comprise reducing throat burning sensation of the treatment liquid beverage (the cathode effluent produced by the electrolytic method has small molecular clusters (5-6), high activity, slightly alkaline pH 8.5,page 1, lines 44-46).

Claim(s) 7 and 22 are rejected under 35 U.S.C. 103 as being unpatentable over Zongyi and Chew et al as applied to claims 1 and 14 above, and further in view of Satoh et al (US 6,251,259). With regards to claims 7 and 22, Zongyi and Chew et al does not teach wherein the two adjacent capacitive emitters are spaced at a distance of less than 10 mm, preferably less than 6 mm. Satoh et al teaches wherein the two adjacent capacitive emitters are spaced at a distance of less than 10 mm, preferably less than 6 mm (a distance between a pair of mutually facing electrode plates 116 and 117 is 0 mm to 5.0 mm, more preferably, 1.5 mm, col 7, lines 5-7). Before the effective filing date of the claimed invention, it would have been obvious to one of ordinary skill in the art, having the teachings of Zongyi, Chew et al and Satoh et al before him or her, to modify the anode and cathode plate of Zongyi and Chew et al to include the distance part as taught by Satoh et al because the combination allows for producing liquid capable of controlling pH and ORP. Claim(s) 10 and 21 are rejected under 35 U.S.C. 103 as being unpatentable over Zongyi and Chew et al as applied to claims 1 and 14 above, and further in view of Fujimura et al (US 2020/0017384). With regards to claim 10, Zongyi and Chew et al does not teach an ORP meter for real-time monitoring and measuring the ORP of the treatment liquid beverage. Fujimura et al teaches an ORP meter for real-time monitoring and measuring the ORP of the treatment liquid beverage (ORP meter 10B is used for monitoring and measuring liquid W2 in real time, paragraph 0048, lines 1-3, Fig. 2). Before the effective filing date of the claimed invention, it would have been obvious to one of ordinary skill in the art, having the teachings of Zongyi, Chew et al and Fujimura et al before him or her, to modify the cell body of Zongy and Chew et al to include the ORP meter of Fujimura et al because the combination allows for a monitoring of ORP in an apparatus for making a safe liquid. With regards to claim 21, Zongyi and Chew et al does not teach a step of real-time monitoring and measuring the ORP of the treatment liquid beverage. Fujimura et al teaches a step of real-time monitoring and measuring the ORP of the treatment liquid beverage (ORP meter 10B is used for monitoring and measuring liquid W2 in real time, paragraph 0048, lines 1-3, Fig. 2).
