Here's a concise summary of US Patent 9629265:

US Patent: 9629265

• Title: Cooling structure of electronic device
• Current Assignee: Cloud Byte LLC. The patent was assigned to CLOUD BYTE LLC on June 27, 2024.
• Inventor: Yorito NAGASAKA
• Filing Date: February 28, 2013
• Issue Date: April 18, 2017
• Abstract: The patent describes a cooling structure for an electronic device housed within a casing. This structure incorporates multiple fans that generate a cooling airflow. Electronic components (heat sources like CPUs) are positioned downstream from these fans, and multiple power source units are placed even further downstream. A key feature is that the power source units are spaced apart in the width direction of the housing, perpendicular to the airflow, and are not linearly aligned with the electronic components in the airflow direction. This arrangement aims to prevent cooling air, warmed by the electronic components, from directly impacting the power source units, thereby improving their cooling efficiency.

Plain-Language Overview of Independent Claims:

• Independent Claim 1: This claim describes an electronic device with a housing, fans, at least one Central Processing Unit (CPU), and multiple memory devices and power source units. The fans are at the front, blowing cooling air towards the rear. The CPU is positioned downstream of the fans, directly in the path of the cooling air. The memory devices are adjacent to the CPU in the width direction of the housing. The power source units are located further downstream from the memory devices and are positioned on opposite sides of the housing, spaced apart in the width direction. Crucially, the power source units are not linearly aligned with the CPU in the direction of airflow, meaning air that cools a memory device will then flow into a power source unit.
• Independent Claim 4: This claim is directed to a cooling structure for an electronic device that includes fans, a CPU, memory devices, and power source units, all arranged within a housing along the cooling airflow path. The CPU is positioned downstream of the fans and is directly cooled by the airflow. The power source units are located further downstream from the memory devices, such that cooling air passing through a memory device subsequently flows into a power source unit. Similar to Claim 1, the power source units are positioned opposite to each other and spaced apart in the width direction of the housing, and are not linearly aligned with the CPU in the longitudinal airflow direction.

Legal Status and Dockets:

US Patent 9629265 is currently Active and is set to expire on September 1, 2034.

According to Google Patents, there has been litigation associated with this patent:

• A PTAB (Patent Trial and Appeal Board) case, IPR2025-01287, was filed but was "Not Instituted - Procedural".
• A US case was filed in the Texas Eastern District Court.
• There is also a record of the "First worldwide family litigation filed."

A search of CAFC 2026 dockets for patent number 9629265 did not yield any direct results mentioning this specific patent or its associated IPR/district court case as being scheduled before the U.S. Court of Appeals for the Federal Circuit in 2026. This aligns with the "Not Instituted - Procedural" status of the IPR, which would typically be a prerequisite for a PTAB appeal to the CAFC. The district court case, while ongoing, is not presently listed on the CAFC's 2026 scheduled cases.
