Samsung Electronics Co., Ltd. et al. v.Netlist, Inc.
Samsung successfully challenged claim 16 of Netlist’s ’912 memory‑module patent, with the Board finding the claim obvious over Ellsberry and other prior art. The term “rank” was construed to include only a single memory device.
Samsung Electronics Co., Ltd. et al. v.Netlist, Inc.
The PTAB held that Samsung and its co‑petitioners proved all 34 claims of Netlist’s ’060 memory‑package patent were obvious over a combination of prior‑art references, rendering the claims unpatentable.
Samsung Electronics Co., Ltd. et al. v.Netlist, Inc.
