US Patent 8934922 Summary

• Title: Method and system for monitoring a mobile station presence in a special area
• Assignee: The current assignee is Avant Location Technologies LLC. The original assignee was AFIRMA CONSULTING & TECHNOLOGIES SL.
• Inventor: Carlos A. Perez Lafuente
• Filing Date: 2014-06-26

• Abstract: The patent describes a method for monitoring a mobile station's presence in a special area. A radio communication device transmits a distinctive signal defining the special area. The mobile station processes received signals to determine if it is receiving this distinctive signal and then sends an updating signal to a mobile telephone network. The network's special operating means adapt an operating parameter (e.g., tariffs or services) based on the mobile station's presence in the special area. The invention is characterized by transmitting "checking data" to the mobile station, which the mobile station uses to identify the distinctive defining signal, and this same checking data is sent to all monitored mobile stations for that special area.

Plain-Language Overview of Independent Claims:

• Independent Claim 1 (Method): This claim describes a method for a mobile network to track a mobile phone's presence in a designated "special area" and adjust its services or tariffs accordingly. The process involves:

  1. A radio device repeatedly broadcasting a unique signal that defines the boundaries of the special area.
  2. The mobile phone listening for and identifying this unique signal.
  3. The mobile phone then sends an update to the mobile network indicating whether it is inside or outside this special area.
  4. The mobile network uses this information to change an operational setting (like billing rates or service availability) for the mobile phone.
     The core inventive step is that the mobile phone itself receives and stores specific "checking data" from the network. This checking data enables the mobile phone to recognize the unique signals that define the special area. The same checking data is provided to all mobile stations intended to be monitored in that particular special area.

• Independent Claim 13 (Mobile System): This claim outlines a mobile system designed to perform the monitoring method described in Claim 1. The system comprises:

  1. Checking Means: Components to detect the mobile phone's presence in the special area. These include:
     • A radio communication device that continuously broadcasts a distinctive signal to define the special area.
     • Within the mobile phone, tools to observe radio channels, process incoming signals, and determine if they correspond to the distinctive signal defining the special area.
  2. Transmission Means: Components for the mobile phone to send an "updating signal" to the mobile network's "special operating means," indicating its presence status in the special area.
  3. Special Operating Means: Located within the mobile network's data processing infrastructure, these means are responsible for adjusting an operational parameter (e.g., a service or tariff setting) based on the mobile phone's reported location.
     The system is specifically characterized by having storage within the mobile station for the "checking data." This checking data is used by the mobile station's processing tools to identify the distinctive signal of the special area. Crucially, the same checking data is provided to any mobile station whose presence in that special area is being monitored.

CAFC 2026 Dockets:
As of April 26, 2026, the provided patent information does not explicitly list any cases related to US8934922 currently before the Court of Appeals for the Federal Circuit (CAFC) for the year 2026. However, it does note that a PTAB case (IPR2025-01260) was filed in 2025 (Not Instituted - Procedural) and several US district court cases have been filed in Texas in 2024 and 2025. These types of cases can sometimes lead to appeals at the CAFC in subsequent years, but no such CAFC dockets for 2026 are listed as authoritative information in the patent details provided.

I do not have authoritative information about any active CAFC 2026 dockets for US patent 8934922.The initial check of the provided patent text did not explicitly list any CAFC dockets for 2026. My Google search for "US patent 8934922 CAFC dockets 2026" also did not yield any specific CAFC cases mentioning US8934922. The search results provide general information about CAFC activity in early 2026, including patent cases, but none directly link to patent 8934922. The USPTO Patent Center search allows searching by patent number, but does not directly provide CAFC docket information.

Therefore, based on the information available, there are no specific CAFC 2026 dockets for US patent 8934922 that can be authoritatively confirmed at this time.
