Office Action

§103
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 . 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 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. In addressing the rejection ground, each claim may not have been separately discussed to the extent the claimed features are the same as or similar to the previously-discussed features; the previous discussion is construed to apply for the other claims in the same or similar way. In the office action, “/” should be read as and/or as generally understood. For example, “A/B” means A and B, or A or B. Claim Objections Claims 1-5 are objected to because of the following informalities: Claim 1 recites ”each channel configurable to”. It should be recited as --each channel configured to--, because configurable is not a positive citation. In addition, Claim 1 recites ”at the source side of the assembly”. It should be recited as --at a source side of the assembly--. Claims 2-5 are objected to based on the dependency from claim 1. Appropriate correction is required. 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 1-5 is/are rejected under 35 U.S.C. 103 as being unpatentable over Kanarellis et al. (hereinafter Kanarellis; US 2020/0235607) in view of Hick (US 2018/0054083), or in view of Hick (US 2018/0054083) and Wendt et al. (hereinafter Wendt; US 10,231,314). Regarding claim 1, Kanarellis discloses a Power over Ethernet (PoE++) Light Emitting Diode (LED) driver and a five-channel controller assembly [e.g. fig. 1/2], the assembly (100) comprises: b. a five-output channel (102) [e.g. when N=5 for POE [N]] with each channel configurable to offer constant voltage and constant current output [e.g. when a LED light fixture is at a constant brightness, the POE output is at a constant voltage and a constant current because when the resistance is fixed when LED is at a constant brightness], thereby facilitating an ethernet-based lighting control system for a plurality of lighting applications [see at least paras. 0044, 0239]; c. an integrated power conversion controller (103) with built-in protection mechanism for managing overloading faults [para. 0018] at the source side of the assembly (100), thereby enabling control of one or more combination of fixtures; and d. a plurality of waterproof and dustproof attributes (104) [e.g. 0041, 0139, 0174, 0175, 0197, 0201, 0206] characterized by a predefined operational temperature range [see at least 0116, 0175]. It’s well-known to provide a PoE input passthrough port for powering and controlling one or more PoE compatible devices. For example, Hick discloses a PoE input passthrough port [see PoE input; the power/data signals pass through a cable/wire from a source to the PoE input] for powering and controlling one or more PoE compatible devices [e.g. LED light fixtures, see at least paras. 0016-0017]. Also, when a LED light fixture is at a constant brightness [e.g. a predetermined brightness, para. 0017 Hick], the POE output is at a constant voltage and a constant current. Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the device disclosed by Kanarellis in accordance with the teaching of Hick regarding POE inputs in order to provide an alternative power and communication data from a well-known PoE input [see at least figs. 7-8]. The combination does not explicitly disclose PoE++ input for powering and controlling one or more PoE+ compatible devices. However, it’s notorious well-known to implement a newer standard, so the it provides improvement and backward compatibility. The official notice of the foregoing fact is hereby taken. For example, Crenshaw (US 9941737) discloses the improvement of PoE++ [see Col. 1, lines 36-48]. Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the device disclosed by Kanarellis in accordance with the teaching of official notice regarding POE++ in order to provide more power/backward compatibility. Assuming, arguendo, the above combination does not disclose constant voltage and constant current output. To provide an output having constant voltage and/or constant current is known to one having ordinary skills. For example, Wendt discloses to provide an output having constant voltage and/or constant current [Col. 10, lines 45-53]. Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the device disclosed by Kanarellis and the official notice in accordance with the teaching of Wendt regarding an output value to loads in order to conquer overload [Col. 10, lines 45-53]. Regarding claim 2, the combination discussed above discloses the assembly (100) as claimed in claim 1, wherein the waterproof and dustproof attributes (104), culminates in an Ingress Protection (IP) rating, suitable for outdoor installation of the assembly (100). The combination does not explicitly disclose Ingress Protection (IP) rating. However, it’s well-known to implement Ingress Protection (IP) rating to achieve improved protection. The official notice of the foregoing fact is hereby taken. For example, Ericson (US 10,724,724) discloses to implement a device with IP rating suitable to be used in hostile environments. Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to implement a device with IP rating suitable to be used in hostile environments. Regarding claim 3, the combination discussed above discloses the assembly (100) as claimed in claim 1, except wherein the assembly (100) is characterized by its compact form factor with dimensions measuring 3 inches in width, 7 inches in length, and 2 inches in height. However, it would have been obvious matter of design choice to have an area of the first receiving capacitive element smaller, since such a modification would have involved a mere change in the size of a component. A change in size is generally recognized as being within the level of ordinary skill in the art. In re Rose, 105 USPQ 237 (CCPA 1955). Regarding claim 4, the combination discussed above discloses the assembly (100) as claimed in claim 1, wherein the assembly (100) integrates with advanced home automation systems through one or more custom firmware drivers, using one or more connected nodes [see at least paras. 0014, 0016-0017, 0036-0037, 0040 Kanarellis]. Regarding claim 5, the combination discussed above discloses the assembly (100) as claimed in claim 1, wherein the assembly (100) is configured with a plurality of network communication capabilities through an Internet Protocol (IP) address and a Media Access Control (MAC) address [see at least paras. 0014-0021, 0199 Kanarellis; since Kanarellis and Hick provide PoE, Bluetooth and internet connection, the device must have IP and MAC address; in addition, a device connected to Internet is notorious well-known to have IP address and MAC address. The official notice of the foregoing fact is hereby taken.], thereby facilitating network-based control, measurement, and monitoring [see at least paras. 0014-0021, and claims of Kanarellis].
