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 . Claim Rejections - 35 USC § 103 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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. 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 of this title, 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 Co., 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. Claim(s) 1-7 and 9-20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Fadell US 20150156031 in view of Sen US 20150341869. Regarding claim 1, Fadell disclose(s) the following claim limitations: A system, comprising: a doorbell comprising a doorbell housing (i.e. doorbell 106 has housing) [54; fig. 8a]; a low-energy transceiver coupled to the doorbell housing, the low-energy transceiver configured to activate in response to the doorbell performing an action selected from group consisting of sending a first transmission, receiving a second transmission, and combinations thereof (i.e. wireless/wired networking component 862 can be Bluetooth or zigbee for low energy transceivers for transmission or reception of signals) [325; fig. 8a]; and a high-energy transceiver coupled to the doorbell housing, the high-energy transceiver configured to deactivate in response to activation of the low-energy transceiver (i.e. wireless/wired networking component 862 can be Bluetooth or zigbee for low energy transceivers for transmission or reception of signals. In some cases, backup means of wireless communication (e.g., 3G/4G) is provided in the event the primary means of communication (e.g., Wi-Fi) becomes disabled, such as due to power outage. The spokesman node “dropping down” to the low communication would imply that the communication switches from high power to lower power which would deactivate the high power communication device.) [59, 62, 325; fig. 8a], wherein the low-energy transceiver and the high-energy transceiver are selected in connection with an automated process determined by a processor based on energy consumption requirements (i.e. The smart hazard detector 104 may be a low-power consuming device that is powered by battery 512 and that includes a low-power communication chip (such as a ZigBee chip) and may participate as a low-power node in the mesh network of the smart-home environment 100 by generating and transmitting messages, relay messages from other devices, as well as by "listen" and sometimes making a corresponding response. However, it should be appreciated that instead of or in addition to being battery powered, the smart hazard detector 104 may be powered by AC voltage from the home. In some embodiments, the smart hazard detector 104 includes a WiFi chipset that enable it to communicate its status to other devices in the smart-home environment 100, to user mobile devices 166, to the central server or cloud-computing system 164, as well as to external managed security services.) [223]. Fadell do/does not explicitly disclose(s) the following claim limitations: wherein the action is less than a predetermined transmission threshold However, in the same field of endeavor Sen discloses the deficient claim limitations, as follows: wherein the action is less than a predetermined transmission threshold (i.e. transmission power can be changed based on an allowable transmission power.) [71,75] It would have been obvious to one with ordinary skill in the art at the time of filing to modify the teachings of Fadell with Sen to have the action is less than a predetermined transmission threshold. It would be advantageous because using the low powered devices when the high-powered device is not necessary would be more energy efficient. Therefore, it would have been obvious to one with ordinary skill, in the art at the time of filing, to modify the teachings of Fadell with Sen to obtain the invention as specified in claim 1.
