Samsung Electronics Co., Ltd. et al. v. Netlist, Inc. et al.

This patent infringement litigation, Samsung Electronics Co., Ltd. et al. v. Netlist, Inc. et al., involves major players in the technology and memory industries. Plaintiffs Samsung Electronics Co., Ltd. and Samsung Semiconductor, Inc. are global operating companies specializing in a wide array of electronics, including semiconductors, smartphones, and memory products. Defendant Netlist, Inc. is a California-based company focused on designing and manufacturing advanced memory technologies for cloud computing and high-performance markets. Netlist operates both as a developer and an assertive licensor of its memory patent portfolio. Google LLC and its parent company, Alphabet, Inc., also operating companies, were later joined as defendants in Netlist's counterclaims.

The dispute centers on allegations of infringement related to Samsung's memory modules, specifically DDR4 LRDIMMs, RDIMMs, and later DDR5 SODIMM and UDIMM memory modules, which implement JEDEC industry standards. Netlist's counterclaims against Google and Alphabet stemmed from their alleged use of these Samsung memory modules in their products. While Samsung initially sought declaratory judgment of non-infringement for several of Netlist's patents, including U.S. Patent Nos. 10,217,523, 10,474,595, 9,858,218, and 7,619,912, among others, the scope of the case in Delaware was narrowed when Judge Richard G. Andrews dismissed claims related to several patents in August 2022. The primary patent at issue, US10217523B1, broadly covers advancements in memory modules and methods of operation, particularly relating to load-reduced memory module technology for enhanced energy efficiency and reliable signal processing at high data rates, often asserted as essential to JEDEC standards.

Filed in the U.S. District Court for the District of Delaware before Judge Richard G. Andrews, the case was stayed on December 1, 2023, pending the resolution of a related contract dispute in the Central District of California concerning a Joint Development and License Agreement (JDLA) between Netlist and Samsung. Delaware is a prominent venue for patent litigation due to a high concentration of major U.S. corporations being incorporated there, providing a common forum under patent venue laws. This litigation is notable as part of a broader, multi-year, multi-venue legal conflict between Netlist and Samsung (and indirectly Google), which arose after Netlist terminated their JDLA in 2020. The case also involved parallel Inter Partes Review (IPR) proceedings at the Patent Trial and Appeal Board, where the '523 patent, for instance, was found valid. Significantly, as of August 5, 2026, Netlist and Samsung announced a comprehensive five-year strategic alliance and cross-licensing agreement, which included the settlement and mutual release of all pending legal actions between the companies, effectively resolving this and other related litigations.

Samsung Electronics Co., Ltd. et al. v. Netlist, Inc. et al. (1:21-cv-01453-RGA) in the U.S. District Court for the District of Delaware saw several key legal developments before ultimately being resolved as part of a broader settlement between the parties.

Key Legal Developments and Outcome:

• Filing & Initial Pleadings (2021-2022)

  • 2021-10-15: Samsung Electronics Co., Ltd. and Samsung Semiconductor, Inc. (collectively, "Samsung") initiated a declaratory judgment (DJ) action against Netlist, Inc. ("Netlist") in the U.S. District Court for the District of Delaware (D. Del.), seeking a declaration of non-infringement for several patents, including US10217523B1, US9858218B2, US10474595B2, US7619912B2, US10860506B2, US10949339B2, and US11016918B2. Samsung later sought to add US11232054B2.
  • 2022-08-01: Judge Richard G. Andrews dismissed Samsung's claims regarding US7619912B2, US10860506B2, US10949339B2, and US11016918B2, and denied Samsung's request to add the US11232054B2 patent to the Delaware action.
  • 2022-09-12: Netlist amended its counterclaims to include patent infringement allegations against Google LLC and Alphabet, Inc. (collectively, "Google Delaware Defendants"), in addition to Samsung.

• Pre-trial Motions & Stays (2022-2023)

  • 2022-11-15: The Google Delaware Defendants filed a Motion to Dismiss, or alternatively, to sever and stay Netlist's counterclaims against them. Oral arguments for this motion were heard on May 22, 2023.
  • 2023-10-10: The D. Del. Court entered an order granting-in-part and denying-in-part Samsung's earlier motion to stay. The court stayed claims related to US9858218B2 and US10474595B2, but allowed claims concerning US10217523B1 to proceed.
  • 2023-12-01: The D. Del. Court entered an Oral Order staying the entire matter until the resolution of any action by another court pertaining to Samsung's and Netlist's rights under their Joint Development and License Agreement (JDLA). This stay was crucial, as a related JDLA breach case was ongoing in the U.S. District Court for the Central District of California (Case No. 8:20-cv-00993).

• Parallel PTAB IPR Proceedings (2021-2025)

  • 2021-11-19: Samsung filed Inter Partes Review (IPR) petitions with the Patent Trial and Appeal Board (PTAB) challenging the validity of Netlist's US9858218B2, US10474595B2, and US10217523B1 patents.
  • IPR2022-00063 (for US10217523B1): This IPR was filed on October 15, 2021, and instituted on May 5, 2022.
    • 2023-05-03: The PTAB issued a Final Written Decision upholding the validity of Netlist's US10217523B1 patent, finding the challenged claims not unpatentable.
    • 2025-03-06: The U.S. Court of Appeals for the Federal Circuit (CAFC) affirmed the PTAB's decision, thus upholding the validity of US10217523B1.
  • IPR2022-00062 (for US9858218B2): The PTAB issued a final written decision on May 8, 2023, finding all challenged claims of this patent unpatentable.
  • Samsung also initiated other IPRs on different Netlist patents, some of which were upheld at the PTAB, such as US10268608B2 (upheld on 2024-12-23).

• Related Litigation and JDLA (2020-2024)

  • 2020-05-28: Netlist filed a breach of contract lawsuit against Samsung in the Central District of California (8:20-cv-00993) related to their Joint Development and License Agreement (JDLA).
  • 2024-05-17: A jury in the Central District of California found that Samsung materially breached the JDLA, concluding that Samsung no longer possessed a license to Netlist's patent portfolio. This outcome directly impacted the Delaware case, as the D. Del. stay was predicated on the resolution of this JDLA dispute.

• Final Disposition: Settlement (2026-08-05)

  • No claim construction (Markman) hearings or specific discovery milestones were noted in the D. Del. case due to its stayed status. Similarly, no trial or verdict occurred in this specific Delaware action. Any trials or verdicts reported (e.g., a $118 million jury verdict in EDTX on November 22, 2024) were from separate, although related, patent infringement cases between the parties in other venues.
  • 2026-08-05: Netlist and Samsung announced a five-year strategic alliance, which includes a comprehensive patent cross-licensing agreement, memory product supply, and technology cooperation. This agreement explicitly brings an end to all pending litigation between the parties, including the Delaware declaratory judgment action (1:21-cv-01453-RGA). While the D. Del. case was officially stayed, this global settlement will lead to its dismissal.

I've found substantial coverage already. Let me verify the specific articles from the news index and search for additional coverage from key outlets.

I've hit my search budget for this task, so I'll summarize based on the articles I was able to locate and verify directly. Note upfront: I could not independently retrieve several items on the supplied news index (the two Biztoc pieces, the Digitimes pieces, the Yahoo Entertainment piece, the 2026-03-16 IPWatchdog RPI piece, and the 2024 Investing.com/Digitimes items), so I do not describe their contents below. Coverage I did find and verify is attributed inline.

Settlement coverage dominates the press narrative. On August 5, 2026, Netlist and Samsung announced a five-year "strategic alliance" that ended all pending litigation. BusinessKorea reported on 2026-08-06 that Samsung will pay an upfront license fee of US$239 million plus quarterly payments of up to US$32.9 million over five years, totaling roughly US$897 million (~1.278 trillion won), in exchange for rights to Netlist's full patent portfolio including server DIMM and HBM technologies, with Samsung also committing to supply up to US$300 million per year (US$1.5 billion total) of memory products and buying 10 million Netlist shares for US$1 million. A Nasdaq article parsed the deal more granularly through executive statements: CEO Chuck Hong called it "one of the most significant patent licensing arrangements in the memory industry"; CFO Gail Sasaki said the upfront fee nets US$200 million after Korean withholding taxes, with 20 quarterly fees of up to US$27.5 million net (US$32.9 million gross), for aggregate net license fees of up to US$750 million; and IP-strategy VP Rich Kim said Netlist will now "focus its full attention on other infringing parties," aided by an ITC cooperation agreement under which Samsung will provide information for future ITC actions against third parties. BusinessKorea framed the deal as removing "the uncertainty of patent disputes" for Samsung in the surging AI semiconductor market, while noting Netlist had previously won US$303 million (April 2023) and US$118 million (November 2024) jury verdicts in the Eastern District of Texas. A Sterne Kessler / Business Wire release from the firm that served as Netlist's lead ITC counsel put the top-line figure slightly higher at "as much as $898 million," and a TradingKey analysis carried by Mitrade reported Netlist shares closed up 58.32% on the announcement — its biggest single-day gain ever — and flagged that Micron, still appealing a US$445 million verdict, may treat the Samsung settlement as a benchmark. The Korea Economic Daily (KED Global) likewise summarized the deal as a "5-year, $897 mn alliance."

Earlier coverage tracks the litigation thread that kept the Delaware case stayed. Netlist's own March 6, 2025 press release, carried by Nasdaq/ACCESS Newswire, is the most on-point piece for this specific case: it announced the Federal Circuit's affirmance of the PTAB's IPR decision upholding all claims of U.S. Patent No. 10,217,523 — the patent at issue in D. Del. 1:21-cv-01453 — and expressly noted that Samsung's October 15, 2021 Delaware declaratory judgment action "remains stayed until the development of any action by any other court pertaining to Samsung's and Netlist's rights under the" the JDLA, with CEO Hong warning Samsung "faces significant exposure based on billions of dollars of potentially infringing sales of its DDR4 LRDIMM products." Subsequent Netlist releases covered by Nasdaq and TMCnet show the fight migrating to the ITC: a September 30, 2025 complaint (Inv. No. 337-TA-1472, instituted late December 2025) asserted six patents including the '523 against Samsung, Google and Super Micro, with an evidentiary hearing set for November 2026, followed by a second investigation (Inv. No. 337-TA-1511, instituted July 15-16, 2026) over HBM and DDR5 RDIMM/MRDIMM patents naming Google, Nvidia, Broadcom and Super Micro as respondents. Reuters (republished in Portuguese via G1 and UOL) reported the second ITC probe as "the latest escalation in a years-long dispute" over high-performance memory, and TrendForce placed it in a broader "memory patent war" roundup. Most recently, IPWatchdog (2026-09-02) covered a Federal Circuit precedential decision in Netlist v. Micron affirming a PTAB obviousness finding against a different Netlist patent (the '339) — noting that Samsung had filed the original IPR and Micron was joined, and that Samsung "later settled with Netlist and withdrew from the appeal" — a direct editorial acknowledgment of the August 2026 settlement's effect on pending appeals.

Where reporting diverges or goes beyond the court record: The headline deal value is stated inconsistently across outlets — US$897 million gross (BusinessKorea, KED Global, and the Nasdaq article's "gross license revenue of up to $897 million") versus "as much as $898 million" (Sterne Kessler) — with the Nasdaq piece clarifying the gap by distinguishing US$750 million in net fees from US$897 million gross. Analyst commentary goes well beyond the docket: TradingKey/Mitrade and the Japanese IP-monetization blog PatentRevenue (the latter summarizing Reuters/CNA) cast the deal as a template for "IP monetization" in the AI memory boom and predicted Micron's pending appeal could make the Samsung terms a reference point; Netlist executives added forward-looking color about CXL hybrid memory and low-power MRDIMM collaboration. One docket-driven point worth flagging against the case metadata: while the metadata identifies this as Judge Richard G. Andrews's case (1:21-cv-01453-RGA), a June 5, 2026 CourtListener entry (Doc. 242) shows the caption now styled 1:21-cv-01453-JLH before Judge Jennifer L. Hall, with the parties stipulating to keep the case stayed "until at least the final disposition of the -1472 Investigation, including any appeals" — consistent with the metadata's "stayed" status, and confirming that the '523 patent claims in Delaware were being held in abeyance pending the ITC proceeding that the August 2026 global settlement then mooted. Notably, almost none of the press coverage centers on the Delaware declaratory judgment action itself — it remained stayed throughout and was resolved only as a component of the broader cross-venue settlement, with coverage focused instead on the EDTX verdicts, PTAB/CAFC validity rulings, and ITC exclusion-order proceedings.

(Note: While she is listed as with Covington & Burling LLP in the 2022 docket entry, some search results indicate she later moved to WilmerHale. However, for the purposes of this case at the time of the docket entry, she was with Covington).

I'll research counsel for each defendant. Let me run several targeted searches.

Good results. Let me verify the specific firms for several attorneys.

I've completed my research. Note upfront: I exhausted my search budget while attempting final verification of a few names (notably the Washington, D.C.-based Google/Alphabet counsel and one possible firm change), so I flag those items as partially sourced. Everything else is grounded in court filings and firm materials.

Defendant representatives

The caption lists three defendants: Netlist, Inc. (defendant/counterclaim-plaintiff) and Google LLC and Alphabet Inc. (counterclaim-defendants, added via Netlist's amended counterclaims on 2022-09-12). Each has separate Delaware local counsel and separate national counsel.

---

1. Netlist, Inc. (Defendant / Counterclaim-Plaintiff)

Delaware local counsel — Shaw Keller LLP, Wilmington, DE

National / lead trial counsel — Irell & Manella LLP, Los Angeles, CA (entered as "of counsel" on Delaware filings):

Later pro hac vice addition:

Irell's newsroom also states McKool Smith PC acted as co-counsel for Netlist in Netlist v. Samsung ("Impact Case of the Year," Apr. 2026); that co-counsel relationship is documented for the Texas litigation, and I did not find a corresponding McKool Smith appearance on the Delaware docket.

---

2. Google LLC and Alphabet Inc. (Counterclaim-Defendants)

Delaware local counsel — Richards, Layton & Finger, P.A., Wilmington, DE

National counsel — Quinn Emanuel Urquhart & Sullivan LLP (listed on the certificate of service in Google/Alphabet's Delaware filings):

---

Notes on completeness and sourcing

• No counsel appears to be missing: all three defendants were represented through the stay and up to the Aug. 2026 stipulated dismissal. Netlist's and Google's respective counsel are confirmed by signed filings and court-issued captions. 2022-08-01 opinion caption listing both sides' counsel
• In-house counsel: I found no in-house attorney appearances on the Delaware docket for any defendant. Netlist's public statements are made by CEO Chuck Hong and CFO Gail Sasaki, but neither appears as counsel of record here; I am not asserting any in-house counsel appearance.
• Role labels: "Local counsel" for Keller/DiBenedetto (Shaw Keller) and Farnan (Richards Layton) is inferred from the D. Del. local-rule practice of using Delaware-bar firms as filing counsel, plus the fact that Keller is docket-flagged "LEAD ATTORNEY" — the labels are my characterization, not docket taxonomy, for the non-Delaware attorneys (who appear as "of counsel" on filings rather than as pro hac vice on the Delaware docket, except Yonan).
• Two items I could not verify before exhausting my search budget: (1) the current firm of David A. Perlson (Quinn Emanuel vs. Hogan Lovells), and (2) the firm/office confirmation for Acharya, Newton, and Shen. Treat those as provisional.
• Contradiction to flag against prior sections: the previously generated "Plaintiff representatives" section lists Alice J. Ahn as being with Covington & Burling in this case; the docket shows she later left and that a notice to remove her as co-counsel was filed — consistent with the section's own caveat that she moved to WilmerHale, but worth noting the withdrawal. Also consistent with prior sections, the case caption migrated from -RGA (Judge Andrews) to -JLH (Judge Jennifer L. Hall), which is how the docket styles counsel entries by late 2025.
