US 10051556

US Patent 10051556, titled "Method for scanning for access point in wireless LAN system," was issued on August 14, 2018, from an application filed on June 9, 2017. The original assignee was KT Corp, but the current assignee is Golden Eye Technologies LLC. The inventors are Byung Wan Yoon and Su Hwan Rim.

Abstract:
The patent discloses a method for scanning for an access point, specifically an active scan method. This method involves a terminal generating and transmitting a probe request frame that includes information on the terminal's signal strength. The goal is to prevent the waste of time and radio resources during the access point scanning process.

Plain-language Overview of Independent Claims:

• Independent Claim 1 (Method for active scanning performed by a station): This claim describes a method where a station (e.g., a mobile device) transmits a probe request frame that contains information about its signal strength to an access point. The station then receives a probe response frame from the access point. Crucially, the access point transmits this response based on the signal strength information it received. The station then decides to access that access point, taking into account both the received probe response frame and a predefined maximum probe response time.
• Independent Claim 9 (Method for active scanning performed by an access point): This claim outlines the method from the perspective of an access point. The access point receives a probe request frame from a station, which includes the station's signal strength information. The access point then transmits a probe response frame to the station, with this transmission being conditional on or based on the received signal strength information. The claim also states that the station's subsequent access to the access point will be based on this probe response frame and a maximum probe response time.
• Independent Claim 10 (Station configured to perform active scanning): This claim describes a station (e.g., a device with a processor and transceiver) that is specifically designed to perform the active scanning method. Its processor is configured to instruct the transceiver to transmit a probe request frame with signal strength information to an access point. It also causes the transceiver to receive a probe response frame, where this response was sent by the access point based on the signal strength information. The station accesses the access point based on this probe response and a maximum probe response time.
• Independent Claim 11 (Access point configured to perform active scanning): This claim covers an access point (e.g., with a processor and transceiver) configured to perform the active scanning method. Its processor is set up to cause the transceiver to receive a probe request frame with signal strength information from a station. The processor then causes the transceiver to transmit a probe response frame to the station, with this transmission being based on the signal strength information. Similar to the other claims, the station's access to this access point is based on the probe response frame and a maximum probe response time.

CAFC 2026 Dockets:
A review of the provided CAFC 2026 docket information (May and June 2026 schedules) does not explicitly mention patent number 10051556. Therefore, as of April 26, 2026, based on the provided information, there is no direct indication of litigation related to US10051556 listed in the May or June 2026 CAFC scheduled cases.US Patent 10051556, titled "Method for scanning for access point in wireless LAN system," was issued on August 14, 2018, from an application filed on June 9, 2017.

Abstract:
The patent describes a method for active scanning in a wireless LAN system. This method involves a station (terminal) generating and transmitting a probe request frame that includes information about the station's signal strength. By leveraging this signal strength information, the method aims to prevent wasted time and radio resources during the access point scanning process.

Plain-language Overview of Independent Claims:

• Independent Claim 1 (Method for active scanning performed by a station): This claim details a method where a wireless station sends a probe request frame, which contains its signal strength information, to an access point. The station then receives a probe response frame from that access point. The key aspect is that the access point's decision to transmit the probe response is based on the signal strength information it received from the station. Subsequently, the station decides to connect to this access point, considering both the received probe response and a maximum allowed time for receiving such responses.
• Independent Claim 9 (Method for active scanning performed by an access point): This claim outlines the process from the access point's perspective. An access point receives a probe request frame from a station, which includes the station's signal strength. The access point then transmits a probe response frame to the station, with this transmission being contingent on the received signal strength information. The claim notes that the station's eventual connection to the access point relies on this probe response and the maximum probe response time.
• Independent Claim 10 (Station configured to perform active scanning): This claim describes a station device comprising a transceiver and a processor. The processor is set up to cause the transceiver to send a probe request frame (including signal strength data) to an access point. It also causes the transceiver to receive a probe response frame, where this response was transmitted by the access point based on the signal strength information. The station is configured to connect to the access point based on the received probe response and the maximum probe response time.
• Independent Claim 11 (Access point configured to perform active scanning): This claim describes an access point device, also including a transceiver and a processor. The processor is configured to enable the transceiver to receive a probe request frame from a station, where this frame includes signal strength information. It then causes the transceiver to transmit a probe response frame to the station, with this transmission being based on the signal strength information. The claim further states that the station's access to this access point is based on the probe response frame and a maximum probe response time.

CAFC 2026 Dockets:
As of April 26, 2026, a search of the CAFC 2026 dockets (specifically the May and June 2026 scheduled cases) did not return any explicit listings for patent number 10051556.

It is noted from the Google Patents page for US10051556 that there are indications of related litigation, including a "US case filed in Texas Eastern District Court" (case 2:25-cv-00898) and a "PTAB case IPR2026-00186 filed (Pending)". However, these are district court and PTAB proceedings, respectively, and were not found listed in the CAFC 2026 dockets.
