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. Claims 8-9 and 33-34 are rejected under 35 U.S.C. 103 as being unpatentable over Griessbaum et al. (US 2023/0024136 A1) in view of Field, III et al. (US 2022/0311273 A1), hereafter Field. Considering claim 8, Griessbaum discloses the use of a generic display 417 (Figures 1 and 4; [0049]), and thus fails to disclose that the display is an LCD display. However, Field teaches the use of an LCD display in an extension module of a modular system ([0048]; [0077]; [0092]). The invention by Griessbaum suggests the use of a generic display being used in an extension module for on-site operator feedback and visual presentation of data/control. The invention by Field suggests at least the use of an LCD screen as a display in an extension module. One of ordinary skill in the art could have simply substituted the known equivalent LCD screen of Field for the generic display required by Griessbaum, and the results of the substitution would have been predictable and repeatable. The function of a display is to provide visual output and feedback to an on-site operator, and it is understood that an LCD screen is fully capable of providing that function as well. Given the functional equivalence, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention to substitute and utilize an LCD screen in the invention by Griessbaum, as taught by Field. Considering claim 9, Griessbaum discloses the use of a generic display 417 (Figures 1 and 4; [0049]), and thus fails to disclose that the display includes at least one LED. However, Field teaches the use of a display including at least one LED in an extension module of a modular system ([0048]; [0077]; [0092]). The invention by Griessbaum suggests the use of a generic display being used in an extension module for on-site operator feedback and visual presentation of data/control. The invention by Field suggests at least the use of an LED-containing screen as a display in an extension module. One of ordinary skill in the art could have simply substituted the known equivalent LED-containing screen of Field for the generic display required by Griessbaum, and the results of the substitution would have been predictable and repeatable. The function of a display is to provide visual output and feedback to an on-site operator, and it is understood that an LED-containing screen is fully capable of providing that function as well. Given the functional equivalence, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention to substitute and utilize an LED-containing screen in the invention by Griessbaum, as taught by Field. Considering claim 33, Griessbaum discloses the use of a generic display 417 (Figures 1 and 4; [0049]), and thus fails to disclose that the display is an LCD display. However, Field teaches the use of an LCD display in an extension module of a modular system ([0048]; [0077]; [0092]). The invention by Griessbaum suggests the use of a generic display being used in an extension module for on-site operator feedback and visual presentation of data/control. The invention by Field suggests at least the use of an LCD screen as a display in an extension module. One of ordinary skill in the art could have simply substituted the known equivalent LCD screen of Field for the generic display required by Griessbaum, and the results of the substitution would have been predictable and repeatable. The function of a display is to provide visual output and feedback to an on-site operator, and it is understood that an LCD screen is fully capable of providing that function as well. Given the functional equivalence, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention to substitute and utilize an LCD screen in the invention by Griessbaum, as taught by Field. Considering claim 34, Griessbaum discloses the use of a generic display 417 (Figures 1 and 4; [0049]), and thus fails to disclose that the display includes at least one LED. However, Field teaches the use of a display including at least one LED in an extension module of a modular system ([0048]; [0077]; [0092]). The invention by Griessbaum suggests the use of a generic display being used in an extension module for on-site operator feedback and visual presentation of data/control. The invention by Field suggests at least the use of an LED-containing screen as a display in an extension module. One of ordinary skill in the art could have simply substituted the known equivalent LED-containing screen of Field for the generic display required by Griessbaum, and the results of the substitution would have been predictable and repeatable. The function of a display is to provide visual output and feedback to an on-site operator, and it is understood that an LED-containing screen is fully capable of providing that function as well. Given the functional equivalence, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention to substitute and utilize an LED-containing screen in the invention by Griessbaum, as taught by Field. Claims 18 and 36 are rejected under 35 U.S.C. 103 as being unpatentable over Griessbaum et al. (US 2023/0024136 A1) in view of Brown et al. (US 2006/0252387 A1). Considering claim 18, Greissbaum discloses a wireless communication module that utilize any of a number of protocols, but fails to explicitly disclose that it includes a component selected from the group consisting of: a low noise amplifier, an active filter, and a power amplifier. However, Brown teaches providing, in a modularized housing 70 (Figure 3; [0045]) with electrical connectivity thereto, at least one of a low noise amplifier, an active filter and a power amplifier 16 (Figures 1; [0029]; [0037]), and further suggests incorporating plural modules or “building blocks” into a single housing ([0045]). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed into to utilize a wireless communication module, according to the teachings of Greissbaum, with the benefits provided by adding a power amplifier, as taught by Brown. The motivation for doing so is to provide a scalable output power, as suggested by Brown ([0037-39]). Considering claim 36, Greissbaum discloses a wireless communication module that utilize any of a number of protocols, but fails to explicitly disclose that it includes a component selected from the group consisting of: a low noise amplifier, an active filter, and a power amplifier. However, Brown teaches providing, in a modularized housing 70 (Figure 3; [0045]) with electrical connectivity thereto, at least one of a low noise amplifier, an active filter and a power amplifier 16 (Figures 1; [0029]; [0037]), and further suggests incorporating plural modules or “building blocks” into a single housing ([0045]). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed into to utilize a wireless communication module, according to the teachings of Greissbaum, with the benefits provided by adding a power amplifier, as taught by Brown. The motivation for doing so is to provide a scalable output power, as suggested by Brown ([0037-39]). Claim 22 is rejected under 35 U.S.C. 103 as being unpatentable over Griessbaum et al. (US 2023/0024136 A1) in view of Pietrasik et al. (US 2017/0316683 A1). Considering claim 22, Griessbaum discloses that the universal interface includes power lines ([0015-16]), digital communication ([0010]) and hardware control lines ([0005]; [0010]; [0059]), but fails to disclose that the universal interface further includes radio-frequency. However, it is known from Piertrasik, to utilize a universal interface 144 (Figure 3C; [0092-93]) that includes digital communication lines (SPI, I2C, USB; [0074-75]; [0081]), power lines ([0071]; [0075]; [0081]; [0092-93]), and radio-frequency ([0074]; [0169-170]) and hardware control lines ([0081]). Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention to utilize radio-frequency as part of the universal interface, as taught by Piertrasik, in the invention by Griessbaum. The motivation for doing so is, as suggested by Piertrasik, is to provide a degree of modularity to the invention, which allows customization of and support of multiple expansion modules with simultaneous or concurrent communication ([0169]). Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Fehrenbach et al.
