Xilinx Becomes Second Defendant in Arbor Global’s New Semiconductors Campaign
New Patent Litigation
One week after suing Samsung in the Eastern District of Texas, Arbor Global Strategies LLC has asserted the same three patents—as well as a fourth—against Xilinx (1:19-cv-01986) in the District of Delaware. The patents are described as relating “to a new type of IC called a ‘stacked die hybrid’”, providing particular value to “Field Programmable Gate Arrays (FPGA) IC modules” by allowing for “high bandwidth and low latency operation”. Arbor Global identifies the accused products as “products and services that utilize Xilinx’s ICs with 3D Stacked Silicon Interconnects (‘SSI’) and [High Bandwidth Memory (HBM)], which include Xilinx’s Virtex FPGA, Virtex UltraScale FPGA, Virtex UltraScale+ FPGA, Kintex UltraScale FPGA, Kintex UltraScale+ FPGA ICs, and Virtex UltraScale+ HBM ICs”.

Plaintiff Managed by Former Intel Board Member Sues Samsung
New Patent Litigation
Arbor Global Strategies LLC has filed suit against Samsung (2:19-cv-00333) in the Eastern District of Texas, alleging infringement of three patents described as relating “to a new type of IC called a ‘stacked die hybrid,’ which allows for an extremely compact processor module with increased data speeds and processing efficiency”, using “inter-cell through-silicon vias (‘TSVs’) within an integrated circuit module, such as between die layers”. Targeted are products (“including Galaxy mobile phones, Galaxy Note, cameras, and Samsung computers”) that use the company’s ARM-based Exynos processor, its ISOCELL image sensor, its DDR4 memory module, and/or one of “Sony’s IMX family of image sensors”. The plaintiff identifies D. James Guzy, a named inventor for the patents-in-suit, as its chairman, president, and cofounder.
