Netlist v. Samsung: $118M Jury Verdict for Memory Module Patent Infringement
Netlist, Inc. secured a $118 million jury verdict against Samsung Electronics and its U.S. affiliates on November 22, 2024, after a ten-day trial before Judge Rodney Gilstrap in the Eastern District of Texas. The jury found willful infringement of three patents covering DDR3 and DDR4 LRDIMM and RDIMM memory modules — making this one of the largest memory IP verdicts in recent years.
How Netlist Won $118M From Samsung in East Texas
Netlist, Inc., a California-based memory technology company, filed suit against Samsung Electronics Co., Ltd., Samsung Electronics America, Inc., and Samsung Semiconductor, Inc. in the Eastern District of Texas on August 1, 2022, asserting infringement of four patents covering advanced memory module architectures. The case was assigned to Judge Rodney Gilstrap, the court’s chief judge and one of the most experienced patent trial judges in the country. The accused products — DDR3 and DDR4 LRDIMMs and RDIMMs — are high-volume server memory components widely used across the data center market.
After 854 days of litigation, a jury trial commenced on November 12, 2024. On November 22, 2024, the jury returned a unanimous verdict finding Samsung liable for willful infringement of claim 16 of the ‘912 Patent, claims 1, 2, and 8 of the ‘417 Patent, and claims 1 and 5 of the ‘608 Patent, and awarding Netlist a total lump-sum reasonable royalty of $118 million — $94M for the ‘912 Patent alone, and $12M each for the ‘417 and ‘608 Patents. Despite the willfulness finding, Judge Gilstrap declined to enhance damages under 35 U.S.C. § 284, citing the absence of egregious culpable behavior under the Halo standard. The court separately dismissed Netlist’s fourth patent (US9858215) without prejudice, as Netlist had dropped it from the case before trial.
The 854-day litigation timeline is notable for a case of this complexity, suggesting efficient but thorough management under Gilstrap’s docket. The decision not to enhance damages despite willfulness underscores how courts continue to apply Halo conservatively, reserving enhancement for the most egregious conduct — a reminder that a willfulness verdict does not automatically translate to multiplied damages. What drove the $94M weighting toward the ‘912 Patent over the other two is not fully explained in the public record, though it likely reflects the relative claim scope and commercial significance attributed to that patent during trial.

Jury verdict for Netlist: what the $118M judgment means for both parties
Unanimous jury verdict: willful infringement on three patents
A unanimous jury found Samsung infringed at least one claim of each of the three asserted patents and that infringement was willful. The court entered judgment under Fed. R. Civ. P. 58 awarding a lump-sum reasonable royalty totalling $118M. Despite willfulness, Judge Gilstrap declined to enhance under 35 U.S.C. § 284, applying the Halo standard that enhancement is reserved for egregious conduct — a discretionary finding that limits Netlist’s recovery to the compensatory award plus pre- and post-judgment interest.
Willful infringement — enhancement deniedNetlist recovers $118M and prevailing-party costs
Netlist secured a $118 million lump-sum royalty, pre-judgment interest at the 5-year Treasury Bill rate compounded quarterly, post-judgment interest at the statutory rate, and court costs. The three asserted patents survived Samsung’s invalidity challenge — the jury found all asserted claims valid. This result significantly strengthens Netlist’s hand in any ongoing or future licensing negotiations with other memory manufacturers, as it now carries a merits verdict from a high-profile East Texas trial.
$118M + interest + costsSamsung faces $118M judgment and strengthened infringement findings
Samsung’s invalidity defenses failed entirely — the jury rejected all invalidity arguments against all three patents. The willfulness finding, while not resulting in enhanced damages here, creates a record that could complicate Samsung’s litigation posture in parallel or future Netlist proceedings. Samsung retains post-trial motion rights (JMOL, new trial) and appeal options to the Federal Circuit, but the jury’s unanimous and comprehensive verdict raises the bar for reversal on appeal.
JMOL and Federal Circuit appeal remain openA $94M single-patent award sets a benchmark for memory IP licensing
The allocation of $94M to the ‘912 Patent alone signals that server-class memory module architectures — specifically load-reduced and registered DIMM designs — carry substantial royalty value in the East Texas framework. For other DRAM and memory module manufacturers, this verdict suggests that Netlist’s portfolio presents credible licensing exposure. Companies shipping DDR4 or DDR5 LRDIMM or RDIMM products should assess their design-around options and FTO exposure against the surviving claims.

Official order — verbatim text
The judgment is structurally notable for several reasons. First, the jury’s unanimous verdict on willfulness demonstrates that Netlist presented a compelling narrative of Samsung’s knowledge of the asserted patents — yet Judge Gilstrap’s independent exercise of Halo discretion constrained the damages ceiling to compensatory levels. Second, the breakdown of the $118M award — $94M for the ‘912 Patent, $12M each for the ‘417 and ‘608 Patents — reflects the jury’s or parties’ relative valuation of each patent’s commercial coverage. Third, the without-prejudice dismissal of the ‘215 Patent is expressly noted in the judgment, preserving Netlist’s future enforcement options. The award of pre-judgment interest compounded quarterly from the date of infringement is consistent with Federal Circuit guidance under General Motors v. Devex and meaningfully increases total recovery beyond the face $118M figure.
US7619912, US11093417 & US10268608 — DDR3/DDR4 Memory Module Architecture
US7619912B2, filed under application US11/862931, is the anchor patent in this action — claiming memory module architectures that address load reduction and signal integrity challenges inherent in high-density DRAM configurations used in server-class LRDIMMs and RDIMMs. US11093417B2 (app. US16/695020) and US10268608B2 (app. US15/820076) extend the portfolio into later-generation DDR4 module designs. All three patents survived Samsung’s invalidity challenge at trial, with the jury finding all asserted claims valid — a significant result given Samsung’s resources and technical depth.
The strategic importance of these patents extends well beyond this single case. LRDIMM and RDIMM modules are the dominant form factor in enterprise server memory, used by every major cloud infrastructure provider. Netlist’s ability to secure a $94M verdict on a single patent covering this technology positions its portfolio as a tier-one enforcement asset in the memory IP space. Other DRAM module manufacturers — including SK Hynix, Micron, and their downstream customers — should treat these surviving claims as active risk vectors, particularly given that the ‘215 Patent was preserved for future assertion.
Should you run an FTO against US7619912, US11093417 & US10268608?
Any company designing, manufacturing, importing, or reselling DDR3 or DDR4 LRDIMM or RDIMM memory modules — or integrating them into servers, workstations, or storage systems — should treat these three patents as priority FTO targets. The jury’s validation of all asserted claims, combined with a $118M damages award, confirms that the claims are both enforceable and commercially significant. The risk is not hypothetical: Samsung, one of the world’s largest memory producers, was found to infringe across all three patents simultaneously.

A $118M verdict with a willfulness finding reshapes licensing dynamics across the DRAM and server memory supply chain.
Willfulness found but damages not enhanced — the Halo gap remains real
Judge Gilstrap’s decision to decline enhancement despite a willfulness verdict reinforces that Halo’s ‘egregious conduct’ standard is a genuine gate, not a rubber stamp. Companies facing willfulness allegations should understand that the legal standard for enhancement is discretionary and fact-intensive — a jury willfulness finding is necessary but not sufficient to trigger multiplied damages.
Three patents all survived invalidity — portfolio breadth matters
Samsung deployed invalidity defenses against every asserted claim across all three patents and lost on all of them. For patent holders in the memory and semiconductor space, this result underscores the value of asserting a diversified claim portfolio — it forces the defendant to win on every front while the patentee needs to prevail on only one. For defendants, it highlights the risk of over-relying on invalidity as a primary trial strategy.
The ‘912 Patent’s $94M weighting reveals claim-level royalty allocation strategy
The disproportionate allocation of $94M to US7619912 relative to $12M each for the other two patents suggests Netlist’s damages experts successfully tied the ‘912 Patent’s claim scope to the highest-volume or highest-value commercial embodiments. IP teams at memory companies should model royalty exposure at the individual claim level — not just across a portfolio — when assessing litigation risk.
The dropped ‘215 Patent dismissal without prejudice preserves future enforcement
Netlist dropped US9858215 before trial and received a dismissal without prejudice. This is a deliberate litigation tactic: preserving the right to assert that patent in a future action, potentially against Samsung or another defendant. Competitors and licensees should treat the ‘215 Patent as live enforcement risk and monitor its status in Netlist’s broader campaign.
Netlist v Samsung — key questions answered
Netlist asserted four patents: US7619912, US11093417, US10268608, and US9858215. The first three proceeded to trial; the ‘215 Patent was dropped before trial and dismissed without prejudice. The jury found Samsung infringed claim 16 of the ‘912 Patent, claims 1/2/8 of the ‘417 Patent, and claims 1/5 of the ‘608 Patent.
Judge Gilstrap applied the Supreme Court’s Halo Electronics standard, which reserves enhanced damages under 35 U.S.C. § 284 for ‘egregious cases of culpable behavior.’ Having presided over the full trial, he concluded that Samsung’s conduct, while willful, did not rise to the level warranting enhancement. The compensatory $118M award, plus pre- and post-judgment interest, was deemed sufficient.
The jury returned a total lump-sum royalty of $118 million, which the court allocated as follows: $94 million for infringement of US7619912 (the ‘912 Patent), $12 million for US11093417 (the ‘417 Patent), and $12 million for US10268608 (the ‘608 Patent). The heavy weighting toward the ‘912 Patent suggests it was tied to the highest-volume or highest-value accused products.
The accused products were Samsung’s DDR3 and DDR4 LRDIMMs (load-reduced dual in-line memory modules), DDR3 and DDR4 RDIMMs (registered DIMMs), and other products with materially the same structures and designs. These are high-volume server memory components widely deployed in enterprise and cloud data center environments.
US9858215 was dismissed without prejudice as part of Netlist’s pre-trial case narrowing (Dkt. No. 325). Judge Gilstrap’s judgment expressly notes this dismissal. Because it was dismissed without prejudice, Netlist retains the right to assert the ‘215 Patent in future litigation against Samsung or other defendants, making it an active risk for the broader memory module industry.
