High voltage battery packs are taught within in the system, thus it is obvious to include a plurality of high battery packs to the plurality of battery interfaces). Regarding claim 11, Ota teaches the electrical device according to Claim 1, wherein: the plurality of electromechanical battery interfaces includes at least two combination battery interfaces, and a first combination interface consists of a plurality of the electromechanical battery interfaces for exchangeable battery packs of at least two different voltage classes such that exchangeable battery packs of different voltage classes cannot be accommodated in it at the same time (paragraph [0040] and figures 4 and 9 show wherein different battery pack with different voltage may be attached. Figure 4 shows wherein one battery pack may be attached and that no other battery pack may be attached). Regarding claim 12, Ota teaches the electrical device according to Claim 1, wherein: the exchangeable battery packs of a highest possible voltage class are 36 V exchangeable battery packs, and the exchangeable battery packs of the lower voltage classes are 18 V and/or 12 V exchangeable battery packs (paragraphs [0040] teaches wherein the voltages of the battery packs may be 36V and 18V and/or 12V). 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. 1. Claims 3 – 8 are rejected under 35 U.S.C. 103 as being unpatentable over Ota (US 20110197389) in view of Willgert (US 20150357684). Regarding claim 3, Ota teaches the electrical device according to Claim 1, but does not explicitly teach wherein the control or regulating circuit is configured to control a plurality of the exchangeable battery packs of a highest possible voltage class sequentially or alternately such that only one of the exchangeable battery packs provides energy to the battery-operated device at any given time. Willgert teaches wherein the control or regulating circuit is configured to control a plurality of the exchangeable battery packs of a highest possible voltage class sequentially or alternately such that only one of the exchangeable battery packs provides energy to the battery-operated device at any given time (defined in paragraph [0059] wherein the control circuitry item 100/102 sequentially operates or discharges a plurality of battery packs to provide power to a tool). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the charging system of the Ota reference with the charging system of the Willgert reference so that the battery packs would improve performance and/or efficacy of the battery packs as power is provided to tool. The suggestion/motivation for combination can be found in the Willgert reference in paragraph [0008] wherein battery performance is improved.

Regarding claim 4, Ota teaches the electrical device according to Claim 1, but does not explicitly teach wherein the control or regulating circuit is configured to control a plurality of exchangeable battery packs of different voltage classes in a parallel connection sequentially or alternately such that a resulting battery voltage of all exchangeable battery packs of the same voltage class does not exceed the maximum permissible supply voltage. Willgert teaches wherein the control or regulating circuit is configured to control a plurality of exchangeable battery packs of different voltage classes in a parallel connection sequentially or alternately such that a resulting battery voltage of all exchangeable battery packs of the same voltage class does not exceed the maximum permissible supply voltage (defined in paragraph [0059] wherein the control circuitry item 100/102 sequentially operates or discharges a plurality of battery packs to provide power to a tool). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the charging system of the Ota reference with the charging system of the Willgert reference so that the battery packs would improve performance and/or efficacy of the battery packs as power is provided to tool. The suggestion/motivation for combination can be found in the Willgert reference in paragraph [0008] wherein battery performance is improved. Regarding claim 5, Ota teaches the electrical device according to Claim 3, but does not explicitly teach wherein the control or regulating circuit is configured to record a temperature value measured in each exchangeable battery pack and to control the exchangeable battery packs sequentially or alternately as a function of the measured temperature values such that it switches from (i) an exchangeable battery pack the measured temperature value of which exceeds a temperature limit value to (ii) an exchangeable battery pack the measured temperature value of which does not exceed the temperature limit value. Willgert teaches wherein the control or regulating circuit is configured to record a temperature value measured in each exchangeable battery pack and to control the exchangeable battery packs sequentially or alternately as a function of the measured temperature values such that it switches from (i) an exchangeable battery pack the measured temperature value of which exceeds a temperature limit value to (ii) an exchangeable battery pack the measured temperature value of which does not exceed the temperature limit value (paragraphs [0033]-[0034] teaches wherein the temperature is sensed by a sensor network item 240 and the information is sent to control the switching assemblies based on the data received. The switching assemblies selectively control which battery pack is to be operated, sequentially or alternately, as it provides power to the tool). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the charging system of the Ota reference with the charging system of the Willgert reference so that the battery packs would improve performance and/or efficacy of the battery packs as power is provided to tool. The suggestion/motivation for combination can be found in the Willgert reference in paragraph [0008] wherein battery performance is improved. Regarding claim 6, Ota teaches the electrical device according to Claim 3, wherein the control or regulating circuit is configured to record the battery voltage of each exchangeable battery pack (defined in paragraph [0054] wherein the battery voltage of the battery pack is measured and compared to a predetermined threshold) but does not explicitly teach wherein to control the exchangeable battery packs sequentially or alternately as a function of the measured battery voltages such that it switches from (i) an exchangeable battery pack, the measured battery voltage of which falls below a minimum voltage limit value to (ii) an exchangeable battery pack, the measured battery voltage of which does not fall below the minimum voltage limit value. Willgert teaches wherein to control the exchangeable battery packs sequentially or alternately as a function of the measured battery voltages such that it switches from (i) an exchangeable battery pack, the measured battery voltage of which falls below a minimum voltage limit value to (ii) an exchangeable battery pack, the measured battery voltage of which does not fall below the minimum voltage limit value (paragraph [0048] teaches determining when a battery voltage falls below a minimum voltage value the user is notified and the switches selectively switch off the battery pack. Paragraph [0061] teaches wherein the voltage is sensed by a sensor network item 240 and the information is sent to control the switching assemblies based on the data received. The switching assemblies selectively control which battery pack is to be operated, sequentially or alternately, as it provides power to the tool). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the charging system of the Ota reference with the charging system of the Willgert reference so that the battery packs would improve performance and/or efficacy of the battery packs as power is provided to tool. The suggestion/motivation for combination can be found in the Willgert reference in paragraph [0008] wherein battery performance is improved.
