Detailed Summary

In IPR2017‑00549, Samsung Electronics challenged claims 1‑4, 6, 7, 10, 13, 17, and 23 of Netlist’s U.S. Patent No. 8,756,364 B1, which covers improvements to multi‑rank memory modules. The petitioner argued that a combination of the Halbert (US 2002/0112119 A1) and Amidi (US 8,250,295 B2) references taught all claim limitations, making the claims obvious. Netlist contended that the claimed use of CAS latency for timing control was novel. The Board, after reviewing the evidence and expert testimony, concluded that the prior art disclosed each limitation and that a person of ordinary skill would have been motivated to combine them, rendering the claims unpatentable under 35 U.S.C. §103(a). Consequently, all ten challenged claims were held unpatentable.
