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.
