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 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. The factual inquiries 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. 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. Claims 1-2, 8-11, and 15-18 are rejected under 35 U.S.C. 103 as being unpatentable over Lewis et al. (US 2014/0189789) in view of Ashwood-Smith (US 2018/0373771). Regarding claim 1, Lewis teaches a land mobile radio (LMR) device comprising: wireless communications circuitry selectively operable over an LMR wireless communications network and a broadband (BB) wireless communications network (Paragraph [0017]….. Communication system 100 includes a number of communication devices, e.g., …… a land mobile radio 118. Communication devices 110-118 can be any type of communication devices with wired, wireless and near-field capabilities. Each of communication devices 111, 112, 114, 116, or 118 is configured to operate on a narrowband network or a broadband network……..Paragraph [0019]…… Two or more of the communication devices 110-118 may be operated by a user/subscriber. For example, the user may operate a land mobile radio (device 118) on a narrowband network to communicate with one or more other devices (not shown) on the narrowband network and, at the same time, the user may operate a broadband-capable smartphone (device 112), on a broadband network to communicate with one or more other devices (not shown) on the broadband network), but does not specifically teach a controller cooperating with the wireless communications circuitry to wirelessly communicate via one of the LMR wireless communications network and the BB wireless communications network based upon a Locator ID Separation Protocol (LISP). However, in related art, Ashwood-Smith teaches a controller cooperating with the wireless communications circuitry to wirelessly communicate via one of the LMR wireless communications network and the BB wireless communications network based upon a Locator ID Separation Protocol (LISP) (Paragraph [0032]……… The communication system of this diagram includes wireless communication access node (WCAN) devices 110, 120, 130, and 140, and electronic devices (EDs) configured to connect to and communicate with the WCAN device(s) (which obviously has a controller), such as wireless communication devices 151, 152, 153, and 154 (e.g., wireless stations (STAs), User Equipments (UEs), mobile wireless communication devices, stationary/fixed location wireless communication devices, etc.), and a cloud network 199. In some examples, the cloud network is implemented within a mobile backhaul communication system within a communication system that provides mobile communication services to the wireless communication devices 151-154. In other examples, the cloud network is implemented within an anchorless mobile backhaul communication system within a communication system that provides mobile communication services to the wireless communication devices 151-154…….. Such an example of anchorless mobile backhaul communication system may be implemented in various ways including based on a locator/identifier separation protocol (LISP)). Therefore, it would have been obvious to one of ordinary skill in the art, at the time the invention was made to use (pre-AIA ) or before the effective filing date of the claimed invention (AIA ) to use Ashwood-Smith’s teaching about a controller cooperating with the wireless communications circuitry to wirelessly communicate via one of the LMR wireless communications network and the BB wireless communications network based upon a Locator ID Separation Protocol (LISP) with Lewis’s invention in order to protect the source IP address. Regarding claims 2, 11, and 18, the combination of Lewis and Ashwood-Smith teach all the claimed elements in claim 1. In addition, Ashwood-Smith teaches the LMR device of Claim 1 wherein the LISP uses Endpoint Identifiers (EIDs) and Routing Locators (RLOCs) based on a Mapping Database (Paragraphs [0033-0034]). Regarding claims 8 and 15, the combination of Lewis and Ashwood-Smith teach all the claimed elements in claim 1. In addition, Lewis teaches the LMR device of Claim 1 wherein the wireless communications circuitry comprises one of WiFi communications circuitry and cellular communications circuitry operable over the BB wireless communications network (Paragraph [0019]…….. Two or more of the communication devices 110-118 may be operated by a user/subscriber…….at the same time, the user may operate a broadband-capable smartphone (device 112), on a broadband network to communicate with one or more other devices (not shown) on the broadband network). Regarding claims 9 and 16, the combination of Lewis and Ashwood-Smith teach all the claimed elements in claim 1. In addition, Lewis teaches the LMR device of Claim 1 wherein the wireless communications circuitry comprises LMR circuitry operable over the LMR wireless communications network (Paragraph [0019]……. Two or more of the communication devices 110-118 may be operated by a user/subscriber. For example, the user may operate a land mobile radio (device 118) on a narrowband network to communicate with one or more other devices (not shown) on the narrowband network (LMR wireless communication network)). Regarding claim 10, Lewis teaches a communications system comprising: a land mobile radio (LMR) wireless communications network; a broadband (BB) wireless communications network; and a land mobile radio (LMR) device comprising wireless communications circuitry selectively operable over the LMR wireless communications network and the BB wireless communications network (Paragraph [0017]….. Communication system 100 includes a number of communication devices, e.g., …… a land mobile radio 118. Communication devices 110-118 can be any type of communication devices with wired, wireless and near-field capabilities. Each of communication devices 111, 112, 114, 116, or 118 is configured to operate on a narrowband network or a broadband network……..Paragraph [0019]…… Two or more of the communication devices 110-118 may be operated by a user/subscriber. For example, the user may operate a land mobile radio (device 118) on a narrowband network to communicate with one or more other devices (not shown) on the narrowband network and, at the same time, the user may operate a broadband-capable smartphone (device 112), on a broadband network to communicate with one or more other devices (not shown) on the broadband network), but does not specifically teach a controller cooperating with the wireless communications circuitry to wirelessly communicate via one of the LMR wireless communications network and the BB wireless communications network based upon a Locator ID Separation Protocol (LISP). However, in related art, Ashwood-Smith teaches a controller cooperating with the wireless communications circuitry to wirelessly communicate via one of the LMR wireless communications network and the BB wireless communications network based upon a Locator ID Separation Protocol (LISP) (Paragraph [0032]……… The communication system of this diagram includes wireless communication access node (WCAN) devices 110, 120, 130, and 140, and electronic devices (EDs) configured to connect to and communicate with the WCAN device(s) (which obviously has a controller), such as wireless communication devices 151, 152, 153, and 154 (e.g., wireless stations (STAs), User Equipments (UEs), mobile wireless communication devices, stationary/fixed location wireless communication devices, etc.), and a cloud network 199. In some examples, the cloud network is implemented within a mobile backhaul communication system within a communication system that provides mobile communication services to the wireless communication devices 151-154. In other examples, the cloud network is implemented within an anchorless mobile backhaul communication system within a communication system that provides mobile communication services to the wireless communication devices 151-154…….. Such an example of anchorless mobile backhaul communication system may be implemented in various ways including based on a locator/identifier separation protocol (LISP)). Therefore, it would have been obvious to one of ordinary skill in the art, at the time the invention was made to use (pre-AIA ) or before the effective filing date of the claimed invention (AIA ) to use Ashwood-Smith’s teaching about a controller cooperating with the wireless communications circuitry to wirelessly communicate via one of the LMR wireless communications network and the BB wireless communications network based upon a Locator ID Separation Protocol (LISP) with Lewis’s invention in order to protect the source IP address. Regarding claim 17, Lewis teaches a method of communicating using a land mobile radio (LMR) device, the method comprising: operating a controller to cooperate with wireless communications circuitry selectively operable over an LMR wireless communications network and a broadband (BB) wireless communications network (Paragraph [0017]….. Communication system 100 includes a number of communication devices, e.g., …… a land mobile radio 118. Communication devices 110-118 can be any type of communication devices with wired, wireless and near-field capabilities. Each of communication devices 111, 112, 114, 116, or 118 is configured to operate on a narrowband network or a broadband network……..Paragraph [0019]…… Two or more of the communication devices 110-118 may be operated by a user/subscriber. For example, the user may operate a land mobile radio (device 118) on a narrowband network to communicate with one or more other devices (not shown) on the narrowband network and, at the same time, the user may operate a broadband-capable smartphone (device 112), on a broadband network to communicate with one or more other devices (not shown) on the broadband network), but does not specifically teach wirelessly communicate via one of the LMR wireless communications network and the BB wireless communications network based upon a Locator ID Separation Protocol (LISP). However, in related art, Ashwood-Smith teaches wirelessly communicate via one of the LMR wireless communications network and the BB wireless communications network based upon a Locator ID Separation Protocol (LISP) (Paragraph [0032]……… The communication system of this diagram includes wireless communication access node (WCAN) devices 110, 120, 130, and 140, and electronic devices (EDs) configured to connect to and communicate with the WCAN device(s) (which obviously has a controller), such as wireless communication devices 151, 152, 153, and 154 (e.g., wireless stations (STAs), User Equipments (UEs), mobile wireless communication devices, stationary/fixed location wireless communication devices, etc.), and a cloud network 199. In some examples, the cloud network is implemented within a mobile backhaul communication system within a communication system that provides mobile communication services to the wireless communication devices 151-154.
