US Patent 11443344: Efficient and secure communication using wireless service identifiers

• Title: Efficient and secure communication using wireless service identifiers
• Current Assignee: Secure Communication Technologies LLC
• Inventors: James A. Proctor, Jr., James Arthur Proctor, III
• Filing Date: July 2, 2021
• Issue Date: September 13, 2022
• Abstract: Systems and methods are provided for reducing communications between servers and a mobile device and providing enhanced security and privacy to wireless beacon services. This can involve a broadcast device transmitting a beacon transmission using a short-range wireless radio, such as Bluetooth or WiFi, and including a MAC address, a first unique identifier, and a beacon service identifier. The mobile device then selects one or more unique identifiers from received beacon transmissions by filtering those beacon transmissions which include the beacon service identifier. The wireless device then takes further action, if the first unique identifier is present among the selected one or more unique identifiers, using stored information from the server. The stored information may be delivered to the wireless device in response to the wireless device sending the first unique identifier to a server, or the stored information may have been previously downloaded.

Plain-Language Overview of Independent Claims:

Please note: The full text of the patent's claims was not provided in the initial context. Therefore, a live search for the claims was necessary to provide this section.

Independent Claim 1 (Method Claim):
This claim describes a method for managing communication with a wireless device using short-range beacons and a central server. The method involves:

• A beacon transmitter sends out a short-range wireless beacon (e.g., Bluetooth or Wi-Fi) containing a unique identifier, a MAC address, and a beacon service identifier.
• A wireless device receives these beacon transmissions.
• The wireless device filters these transmissions, only selecting those that contain a specific beacon service identifier.
• The wireless device then performs an action based on whether a particular unique identifier from the filtered beacons is present. This action uses information about the entity associated with that unique identifier, which is obtained from one or more servers via a separate, long-range radio connection. The information from the server can be pre-downloaded or requested when the unique identifier is detected.

Independent Claim 10 (System Claim):
This claim describes a system that performs the method outlined in Claim 1. The system includes:

• A beacon transmitter configured to transmit short-range wireless beacon transmissions with a MAC address, a unique identifier, and a beacon service identifier.
• A wireless device configured to receive these beacon transmissions using a short-range radio.
• The wireless device is also configured to filter these transmissions based on the beacon service identifier and, if a specific unique identifier is present among the filtered results, perform a further action using stored information related to an entity associated with that unique identifier.
• One or more servers are configured to store and transmit this information to the wireless device via a long-range radio connection.

Independent Claim 18 (Non-Transitory Computer-Readable Medium Claim):
This claim covers a non-transitory computer-readable medium (e.g., a storage device) storing instructions that, when executed by a processor, cause a wireless device to perform the steps described in Claim 1. Specifically, it includes instructions for:

• Receiving short-range beacon transmissions.
• Selecting unique identifiers by filtering for a beacon service identifier.
• Taking further action if a unique identifier is present, using stored information about an associated entity from a server.

CAFC 2026 Dockets:

A review of the provided patent information and general search for CAFC dockets for 2026 related to US11443344 did not yield any specific CAFC cases. The litigation listed in the Google Patents information pertains to District Courts (Texas Western and Eastern Districts) and PTAB (Patent Trial and Appeal Board) cases, including IPR2025-01182 and IPR2025-01050, but no cases in the Court of Appeals for the Federal Circuit for 2026 were explicitly identified. Therefore, I cannot authoritatively state the presence of CAFC 2026 litigation based on the available information.
