`DETAILED ACTION
`
`Notice of Pre-AIA or AIA Status
`
`1.
`
`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
`
`2.
`
`The information disclosure statement (IDS) submitted on 4/3/19 was filed after the mailing date
`
`of the Non-Final Office Action on 2/11/19. The submission is in compliance with the provisions of 37
`
`CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner.
`
`Claim Rejections - 35 USC § 103
`
`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 set forth in Graham v. John Deere C0,, 383 U.S. 1, 148 USPQ 459 (1966),
`
`that are applied 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.

`
`Claims 1, 3-5, 7-8, and 11-12 are rejected under 35 U.S.C. 103 as being unpatentable over
`
`Tabata (JP 2015072820 A) (utilizing the 10/3/13 filing date) in further in view of Huang et al. "Electricity
`
`generation from a floating microbial fuel cell".
`
`4.
`
`Regarding claim 1, Tabata discloses a microbial fuel cell (Translation; [0001]) comprising: a liquid
`
`comprising organic matter (Translation; [0017]); an anode (50) (Fig. 12) placed in the liquid comprising
`
`the organic matter; an air cathode (60) having an air intake portion (the portion of the cavity of the
`
`hollow fiber membrane 40 above the liquid level; see annotated Fig. 12 below) for taking air into the air
`
`cathode (Translation; [0029]); and an oxygen-blocking portion (70) for blocking oxygen from dissolving in
`
`the liquid comprising the organic matter through the surface of the liquid comprising the organic matter
`
`(the oxygen-blocking portion is hovering over the surface of the liquid and is thus capable of blocking
`
`oxygen; see annotated Fig. 12 reproduced below), the air intake portion passing through the oxygen-
`
`blocking portion (see annotated Fig. 12 reproduced below), the air cathode further having cathodes (as
`
`per Fig. 10(b) and [0082] of the translation, ”the plurality of cross-sections” are being interpreted as
`
`multiple cathodes; see annotated Fig. 12 reproduced below) and an air chamber (the portion of the
`
`cavity of the hollow fiber membrane 40 below the liquid level; see annotated Fig. 12 reproduced below)
`
`between the cathodes, the cathodes being in contact with the air chamber (see annotated Fig. 12
`
`reproduced below), the cathodes and the air chamber being placed in the liquid (see annotated Fig. 12
`
`reproduced below), the air cathode being an air cathode in which air is capable of being passed through
`
`the air intake portion and being taken into the air chamber and air taken into the air chamber is capable
`
`of being in contact with the air cathode (see annotated Fig. 12 reproduced below).

`
`Tabata further discloses that the oxygen-blocking portion supports an upper end portion of the
`
`anode and the air cathode and allows the microbial fuel cell to change positions relative to the liquid
`
`(Translation; [0026]).
`
`6.
`
`Tabata also discloses wherein the anode comes in contact with organic substances in organic
`
`waste water and electricity-producing bacteria and electrons are released from the bacterial cell to
`
`anode (Translation; [0004], [0032]).
`
`7.
`
`Tabata also appears to be open to modifications of the oxygen-blocking portion as long as it
`
`retains the function of supporting a membrane between the air cathode and anode (Translation;
`
`[0044]).
`
`

`

`Application/Control Number: 15/032,232
`Art Unit: 1724
`
`Page 5
`
`8.
`
`Tabata does not disclose wherein the oxygen-blocking portion having floating properties for the
`
`liquid comprising the organic matter, the oxygen-blocking portion being directly in contact with the
`
`surface of the liquid comprising the organic matter, the oxygen-blocking portion being so placed that the
`
`oxygen-blocking portion is capable of fluctuating following a fluctuation of a position of the liquid
`
`surface, and the entirety of the oxygen-blocking portion being placed above the anode in a direction
`
`transverse to the surface of the liquid.
`
`9.
`
`Huang teaches a microbial fuel cell (Abstract) comprising: a liquid comprising organic matter
`
`(sea water; Fig. 1); an oxygen-blocking portion (rubber stopper; Fig. 1) for blocking oxygen from
`
`dissolving in the liquid comprising the organic matter through the surface of the liquid comprising the
`
`organic matter (”preventing excessive oxygen flux into the anode chamber”; P3092C1), the oxygen-
`
`blocking portion having floating properties for the liquid comprising the organic matter (rubber stopper
`
`can float; Fig. 1), the oxygen-blocking portion being directly in contact with the surface of the liquid
`
`comprising the organic matter (Fig. 1), the oxygen blocking portion being so placed that the oxygen-
`
`blocking portion is capable of fluctuating following a fluctuation of a position of the liquid surface (the
`
`floating property of the rubber stopper allows the rubber stopper to fluctuate with the sea water level;
`
`Fig. 1) ) to overcome the limitation due to water depth (P308:C2), and the entirety of the oxygen-
`
`blocking portion being placed above the anode (anode; Fig. 1) in a direction transverse to the surface of
`
`the liquid (Fig. 1) maximizing the amount of anode that can be embedded in the marine sediment
`
`(P312:C1) and thus increasing the power output of the fuel cell (P311:C2).
`
`10.
`
`It would have been obvious to one of ordinary skill in the art at the time the application was
`
`filed to utilize the oxygen-blocking portion of Huang for the oxygen-blocking portion of Tabata to
`
`overcome the limitation due to water depth and the skilled artisan would have a reasonable expectation
`
`of success in doing so thus reading on the claim language ”wherein the oxygen-blocking portion having
`
`floating properties for the liquid comprising the organic matter, the oxygen-blocking portion being
`
`

`

`Application/Control Number: 15/032,232
`Art Unit: 1724
`
`Page 6
`
`directly in contact with the surface of the liquid comprising the organic matter, and the oxygen-blocking
`
`portion being so placed that the oxygen-blocking portion is capable of fluctuating following a fluctuation
`
`of a position of the liquid surface”.
`
`11.
`
`It would have been obvious to one of ordinary skill in the art at the time the application was
`
`filed to locate the oxygen-blocking portion of modified Tabata such that the entirety of the oxygen-
`
`blocking portion is placed above the anode as taught in Huang maximizing the amount of anode that can
`
`be embedded in the marine sediment and thus increasing the power output of the fuel cell and the
`
`skilled artisan would have a reasonable expectation of success in doing so.
`
`12.
`
`Regarding claim 3, modified Tabata discloses all the limitations of the microbial fuel cell above
`
`and further discloses wherein the oxygen-blocking portion floats on the surface of the liquid comprising
`
`the organic matter (Huang; Fig. 1).
`
`13.
`
`Regarding claims 4 and 7, modified Tabata discloses all the limitations of the microbial fuel cell
`
`above and further discloses wherein the oxygen-blocking portion is in contact with the air cathode
`
`(Tabata; through the hollow fiber membrane 40; Fig. 12).
`
`14.
`
`Regarding claims 5 and 8, modified Tabata discloses all the limitations of the microbial fuel cell
`
`above and further discloses wherein the oxygen-blocking portion is coupled to the air cathode (Tabata;
`
`via the hollow fiber membrane 40; Fig. 12).
`
`15.
`
`Regarding claim 11, modified Tabata discloses all the limitations of the microbial fuel cell above
`
`and further discloses that by having multiple microbial fuel cells, it is possible to increase the power
`
`generation and the water throughput (Translation; Tabata; [0073]).
`
`16.
`
`Thus modified Tabata discloses wherein the air cathode is one of a plurality of air cathodes
`
`having an air intake portion for taking air into the air cathode, each of the plurality of air cathodes
`
`comprising a cathode, and the anode is located between the respective cathodes of the plurality of air
`
`cathodes (Tabata; see modified Fig. 12 reproduced below).

`
`17.
`
`It would have been obvious to one of ordinary skill in the art at the time the application was
`
`filed to structure the plurality of air cathodes of modified Tabata as claimed because it would make it
`
`possible to increase the power generation and the water throughput and the skilled artisan would have
`
`a reasonable expectation of success in doing so.
`
`18.
`
`Regarding claim 12, modified Tabata discloses all the limitations of the microbial fuel cell above
`
`and further discloses that the oxygen-blocking portion holds a plurality of microbial fuel cells (Tabata;
`
`Fig.8). Furthermore, modified Tabata discloses that by increasing the number of microbial fuel cells, the
`
`power generation and the water throughput increases (Translation; Tabata; [0073]). Therefore by
`
`increasing the contact area of the oxygen-blocking portion in 100% of the total surface area of the liquid
`
`surface, the number of sites for the placement of microbial fuel cells increases which thus will
`
`necessarily increase the power generation and the water throughput.
`
`19.
`
`Thus, in an effort to maximize the power generation and the water throughput, the skilled
`
`artisan would have found it obvious to maximize the contact area of the oxygen-blocking portion in
`
`100% of the total surface area of the liquid surface such that the contact area is within the claimed
`
`

`

`Application/Control Number: 15/032,232
`Art Unit: 1724
`
`Page 8
`
`range of 50% in order to maximize the number of microbial fuel cells allowing for an increase in power
`
`generation and the water throughput.
`
`20.
`
`It would have been obvious to one of ordinary skill in the art at the time the application was
`
`filed to increase the contact area of the oxygen-blocking portion of modified Tabata to within the
`
`claimed range in order to increase the number of microbial fuel cells to in-turn increase the power
`
`generation and the water throughput and the skilled artisan would have a reasonable expectation of
`
`success of doing so.
`
`Response to Arguments
`
`21.
`
`Applicant’s arguments with respect to claim 1 have been considered but are moot because the
`
`arguments do not apply to any of the combination of references being used in the current rejection.
`
`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 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 date of this final action.
