Each rectifier unit 2 converts the AC power from the AC power source P into a DC Power. The i-th rectifier unit 2 of the N rectifier units 2 outputs the i-th DC power PAi.

In other words, the power conversion system 1 can meet the power factor requirements. Consequently, the efficiency of the power conversion system 1 is increased, and the power loss is reduced).
Liu does not expressly disclose a plurality of different positions of an anode.
Grant teaches (see figures 1-42) a plurality of output terminals physically mounted in parallel (figures 5 and 6, part plurality of output terminals of the DC-DC converter circuit inside of 9A-9J) (figure 42, part DC-DC converter circuit generated by 154 and 150) at a plurality of different positions of an anode (figures 5 and 6, part plurality of different positions [upper or lower corners] of anode A) (paragraphs [0092]-[0096]; cathode plates 1 and anode plates 2 are marked A C A C A and are viewed end on (i.e. from above in a vertical plate system). The power converters 9 are represented by circles. The plates (and hence the interelectrode gaps 3) may be supplied from both edges (corners) using all the converters shown (9A to 9H inclusive)… Considerations such as reducing converter count, optimal converter power and obtaining even current distribution determine which converter distribution is employed.).
It would have been obvious to one having ordinary skill in the art before the effective filling date of the claimed invention to apply the rectifier circuit of Liu to the electrodeposition device as taught by Grant and obtain a rectifier circuit comprising: an alternating current-to-direct current converter circuit that generates one or more direct current signals from an alternating current signal of an input terminal; and a plurality of direct current-to-direct current converter circuits that convert the one or more direct current signals from the alternating current-to-direct current converter circuit to a plurality of corresponding child direct current signals comprising separately reduced voltages from the one or more direct current signals at a plurality of output terminals physically mounted in parallel at a plurality of different positions of an anode, because the combination result in more efficient and robust power supply for the electrodeposition device (paragraphs [0087]-[0088] and [0096]).
Regarding claim 2, Liu and Grant teach everything claimed as applied above (see claim 1). Further, Liu discloses (see figures 1-22) a front-end stage including the alternating current-to-direct current converter circuit (figures 1 and 2, part AC/DC 2); and a back-end stage including the plurality of direct current-to-direct current converter circuits (figures 1 and 2, part plurality of DC-DC converter circuit 34 and 35), wherein the back-end stage (figures 1 and 2, part plurality of DC-DC converter circuit 34 and 35) is connected to one or more portions of a device (figure 22, parts device generated by b and L) and provides current to the one or more portions of the device (figure 22, parts device generated by b and L) via the plurality of output terminals (figures 1 and 2, part output terminals from 32 and 33; Po1-PoN).

Converter 151 creates a dc supply 152 from an ac supply 153 (e.g. 230V, 50 Hz). This converter 151 may include a power-factor correction stage. An intermediate supply 152 may be any convenient dc voltage but may also be the dc voltage derived from a power factor correction stage and may contain substantial voltage ripple as well as being of a voltage greater than the peak voltage of the ac supply 153. For efficient functioning of the buck regulator 150, the intermediate voltage supplied to it at the intermediate voltage rails 155 should not be too far removed from the output voltage (i.e. the cell voltage). Typically the input voltage of this converter should not be much more than ten times the output voltage when the converter is a simple buck converter. Hence an intermediate converter 154 may be required to convert the output voltage of converter 151 to a voltage appropriate for input to the converter 150), wherein the back-end stage (figure 42, part DC-DC converter circuit generated by 154 and 150) is connected to one or more portions (figure 42, part anode and cathode of cell 146)(figures 5 and 6, parts anodes A and cathodes C provided by 9A-9j) of an electrodeposition device (figures 5 and 6) (paragraphs [0002]-[0004]; The present invention relates to an apparatus for the electro-production of metals.

The anode is made positive and the cathode made negative so that an electric current passes through the electrolyte from anode to cathode. In electrorefining (ER), the metal anode is soluble. That is to say that the metal enters into the electrolyte under the influence of the potential between the anode and cathode. For example, in the electrorefining of copper, the anode is made of copper and the copper enters the electrolyte from the anode. The metal, now in the electrolyte, is transported through or by the electrolyte to the cathode where it is deposited) and provides current to the one or more portions (figures 5 and 6, parts anodes A and cathodes C provided by 9A-9j) of the electrodeposition device (figures 5 and 6) via the plurality of output terminals (figure 42, part anode and cathode of cell 146)(figures 5 and 6, parts outputs from 9A-9j) (paragraph [0033]; a first aspect of the invention there is provided an apparatus for use in the electro-production of metals, comprising a plurality of anodes and a plurality of cathodes in an interleaved configuration, wherein each anode and cathode pair forms a cell; a plurality of power supplies, each cell associated with one or more respective power supplies; and the power supplies are arranged to control a direct current in the one or more cells to a predetermined value).

For example, the first rectifier unit of the N rectifier units 2 outputs the first DC power PA1, and the N-th rectifier unit of the N rectifier units 2 outputs the N-th DC power PAN); and a back-end stage including the plurality of direct current-to-direct current converter circuits (figures 1 and 2, part plurality of DC-DC converter circuit 34 and 35) arranged in series (paragraph [0110]; n some other embodiments, the i-th total output terminal 4 of the three power conversion systems 1 are connected with each other in series to output the i-th total output power Poi) to provide the plurality of corresponding child direct current signals (figures 1 and 2, part plurality of child DC at 342 and 352) generated from the direct current signal (figures 1 and 2, part plurality of DC-DC converter circuit 34 and 35) to a plurality of positions (figure 22, parts plurality of positions at b and L).

For efficient functioning of the buck regulator 150, the intermediate voltage supplied to it at the intermediate voltage rails 155 should not be too far removed from the output voltage (i.e. the cell voltage). Typically the input voltage of this converter should not be much more than ten times the output voltage when the converter is a simple buck converter. Hence an intermediate converter 154 may be required to convert the output voltage of converter 151 to a voltage appropriate for input to the converter 150) to provide the plurality of corresponding child direct current signals generated from the direct current signal (figures 5 and 6, part plurality of DC-DC converter circuit inside of 9A-9J) to a plurality of positions of an electrically conductive surface (figures 5 and 6, part surface of anode A) (paragraphs [0092]-[0096]).

Response to Arguments
Applicant's arguments filed 11/13/2025 have been fully considered but they are not persuasive.
Applicant’s argues on pages 10-12 of the Applicant's Response (“Liu, whether considered singly or in combination with the other cited references, fails to describe, teach, or suggest each limitation recited by independent claims 1, 11, and 16. For example, Liu, whether considered singly or in combination with the other cited references, fails to describe, teach, or suggest "a plurality of direct current-to-direct current converter circuits that convert the one or more direct current signals from the alternating current-to-direct current converter circuit to a plurality of corresponding child direct current signals comprising separately reduced voltages from the one or more direct current signals at a plurality of output terminals physically mounted in parallel at a plurality of different positions of an anode," as recited by currently amended independent claim 1. As discussed above, Liu does not disclose the limitations of the currently amended independent claims. The additional cited prior art references also do not teach the above-cited limitations of the claims”).
The Examiner respectfully disagrees with Applicant’s arguments, because the 103 combination of Liu and Grant teach the claimed limitation. The primary reference Liu discloses a plurality of direct current-to-direct current converter circuits (figures 1 and 2, part plurality of DC-DC converter circuit 34 and 35) that convert the one or more direct current signals (figures 1 and 2, part DC at 22 from output of 2) from the alternating current-to-direct current converter circuit (figures 1 and 2, part AC/DC 2) to a plurality of corresponding child direct current signals (figures 1 and 2, part plurality of child DC at 342 and 352) comprising separately reduced voltages (figures 1 and 2, part reduced voltages at 342 and 352) from the one or more direct current signals (figures 1 and 2, part DC at 22 from output of 2) at a plurality of output terminals (figures 1 and 2, part output terminals from 32 and 33; Po1-PoN) physically mounted in parallel (figures 1, 2 and 22, part output parallel connected between 32 and 33) at a plurality of different positions (figure 22, parts plurality of different positions at b and L) (paragraphs [0042]-[0046]; each power converter 3 is electrically connected with a corresponding rectifier unit 2. Each power converter 3 includes an input terminal 31, a first output terminal 32 and a second output terminal 33. The input terminal 31 of each power converter 3 is electrically connected with the output terminal 22 of the corresponding rectifier unit 2 to receive the DC power PAi from the corresponding rectifier unit 2. The first output terminal 32 of the first power converter 3 and the second output terminal 33 of the N-th power converter 3 are connected in parallel to form the N-th total output terminal 4… each power converter 3 includes a first DC/DC conversion circuit 34 and a second DC/DC conversion circuit 35. The first DC/DC conversion circuit 34 has an input terminal 341 and an output terminal 342. The second DC/DC conversion circuit 35 has an input terminal 351 and an output terminal 352. The input terminal 341 of the first DC/DC conversion circuit 34 and the input terminal 351 of the second DC/DC conversion circuit 35 are connected in parallel with the input terminal 31 of the corresponding power converter 3… if the required power levels for different total output terminals 4 are different, the input power levels at the input terminals 31 of the power converters 3 may be regulated to be consistent according to the practical requirements. In other words, the power conversion system 1 can meet the power factor requirements. Consequently, the efficiency of the power conversion system 1 is increased, and the power loss is reduced). Grant teaches a plurality of output terminals physically mounted in parallel (figures 5 and 6, part plurality of output terminals of the DC-DC converter circuit inside of 9A-9J) (figure 42, part DC-DC converter circuit generated by 154 and 150) at a plurality of different positions of an anode (figures 5 and 6, part plurality of different positions [upper or lower corners] of anode A) (paragraphs [0092]-[0096]; cathode plates 1 and anode plates 2 are marked A C A C A and are viewed end on (i.e. from above in a vertical plate system). The power converters 9 are represented by circles. The plates (and hence the interelectrode gaps 3) may be supplied from both edges (corners) using all the converters shown (9A to 9H inclusive)… Considerations such as reducing converter count, optimal converter power and obtaining even current distribution determine which converter distribution is employed.). It would have been obvious to one having ordinary skill in the art before the effective filling date of the claimed invention to apply the rectifier circuit of Liu to the electrodeposition device as taught by Grant and obtain a rectifier circuit comprising: an alternating current-to-direct current converter circuit that generates one or more direct current signals from an alternating current signal of an input terminal; and a plurality of direct current-to-direct current converter circuits that convert the one or more direct current signals from the alternating current-to-direct current converter circuit to a plurality of corresponding child direct current signals comprising separately reduced voltages from the one or more direct current signals at a plurality of output terminals physically mounted in parallel at a plurality of different positions of an anode, because the combination result in more efficient and robust power supply for the electrodeposition device (paragraphs [0087]-[0088] and [0096]). Therefore, the combination of Liu and Grant meet the claimed limitation.
