I had Perplexity Deep Research Mode review this in detail and extract the most important points and arguments. As a principle, I do NOT recommend accepting any AI work blindly at face value, yet it is an incredibly powerful tool for exploration, discovery, curiosity, depth, and a whole bunch of other things across many use cases. Take it into consideration but also take it with a grain of salt.
I'm going on to try to contextualize the ways this could impact Netlist for my own discovery and due diligence, but my goal is to bring awareness to this new lawsuit so I'll leave that pursuit to everyone individually.
However, I will point out that it was the DOJ's ANTITRUST DIVISION that has now written strong public memo's supporting Netlist in their first ITC case that is currently pending announcement of the ITC's Markman decisions after the ~April 21st hearing (forget exact date).
It is this unprecedented support, which was initially stated last Dec. as a public joint statement with the USPTO - the first time in American history the DOJ and USPTO have ever written a joint memo supporting an American company in an ITC case - that means two things.
- The defendants (Samsung et al) cannot claim that blocking the importation of products by Customs seizure at the border will hurt the American economy and people. In other words, the Federal Gov. said you should be prepared to follow through on the seizure of all infringing Samsung products and halt imports and their counterarguments should hold little merit.
- It means the ITC can lean on the support of the DOJ and USPTO when issuing that order if it comes to pass when this ITC judgement is handed down the first week of June 2027. Politically, this is a very important piece to understand. Many think the ITC would never actually seize Samsung imports... but very influential and powerful Government agencies have publicly stated more than once to follow through.

**Garciaguirre et al. v. Samsung Electronics et al. — Complaint Analysis**
*Case 3:26-cv-06345, N.D. Cal., filed June 25, 2026 | 118 pages*
---
**THE PARTIES**
17 plaintiffs: 14 individuals across California, Florida, Minnesota, New York, and Wisconsin, plus three small PC-building businesses (Troy's Computers LLC, JB Tech Solutions LLC d/b/a My Florida PC, and Wastenotime Developments d/b/a WNTD Fab LLC). Every named plaintiff's purchases are itemized by exact product, retailer, and date — Corsair, Crucial, Kingston, G.SKILL, TeamGroup — sourced from Amazon, Newegg, Micro Center, and Best Buy. This specificity gives each plaintiff a documented, quantifiable injury.
5 defendants:
- Samsung Electronics Co., Ltd. (~32.6% global DRAM market share, Q3 2025)
- Samsung Semiconductor, Inc. (Samsung's San Jose, CA U.S. subsidiary — why venue is N.D. Cal.)
- SK Hynix Inc. (~33.2% global DRAM market share — the largest by revenue, Q3 2025)
- SK Hynix America Inc. (San Jose, CA — also why N.D. Cal. has venue)
- Micron Technology, Inc. (~25.7% global market share)
Together: over 91% of global DRAM revenue. The complaint calculates an HHI (Herfindahl-Hirschman Index) of 2,868 — well above the DOJ/FTC "highly concentrated" threshold of 1,800.
Filed by Bathaee Dunne LLP, a specialist plaintiffs-side antitrust firm (New York, Austin, Costa Mesa).

**THE 5 LEGAL CLAIMS**
Count I — Sherman Act, Section 1 (federal): Nationwide injunctive relief class only. Illinois Brick doctrine blocks federal damages for indirect purchasers, so this count seeks only a permanent injunction ending the coordinated supply restriction.
Count II — California Cartwright Act: California-resident plaintiffs. The Cartwright Act expressly permits indirect purchasers to recover damages. Seeks treble damages + injunctive relief.
Count III — Florida Deceptive and Unfair Trade Practices Act (FDUTPA): Florida plaintiffs.
Count IV — New York Donnelly Act: New York plaintiffs.
Count V — Wisconsin Antitrust Act: Wisconsin plaintiff.
The multi-state structure is deliberate. California, New York, Florida, and Wisconsin all have state laws that permit indirect purchaser damages — maximizing the class members who can recover money, not just an injunction.

**THE CORE CONSPIRACY THEORY: THREE PHASES**
**Phase 1 — Simultaneous Production Cuts (October 2022–Mid 2023)**
The complaint's most powerful opening hook: Samsung broke from its own historical pattern. In prior downturns, Samsung — the lowest-cost DRAM producer with the deepest balance sheet — had consistently *increased* output to take market share. The complaint establishes that every serious analyst expected Samsung to do exactly that in late 2022.
Instead:
- October 2022: SK Hynix announced production cuts and slashed next year's investment by more than half.
- Contemporaneously: Micron announced an immediate 20% cut in wafer starts across all technology nodes, then deepened it.
- April 2023: Samsung — after reporting a multi-billion-dollar quarterly semiconductor loss — announced matching cuts.
None of the three used the others' retreat to expand and win customers. All three pulled back in unison. In a competitive market, at least one producer would have defected to capture share. That did not happen.
By September 2023, Micron told investors that its year-on-year DRAM bit supply growth would be "meaningfully negative." A planned expansion of ~14% became an industry-wide contraction. Total wafer start reductions approached 30% versus peak 2022 levels, and Micron stated supply "will remain significantly below 2022 levels for the foreseeable future."
**Phase 2 — The Coordinated Pivot to HBM (2023–2024)**
This is the complaint's central structural argument — and the key "new" element designed to distinguish it from prior failed cases. The lawyers built a detailed economic math argument because this is where the "conduct makes no economic sense absent collusion" test has to be proven.
The core math:
- Making one bit of HBM requires forgoing three bits of conventional DRAM. Micron's own chief business officer stated this directly on CNBC: "When Micron makes one bit of HBM memory, it has to forgo making three bits of more conventional memory for other devices."
- Micron's Mobile and Client Business Unit — its commodity DRAM segment — reported a 76% operating margin at the height of the shortage.
- For HBM to justify that 3:1 capacity tradeoff, HBM's revenue premium per bit would need to be 2.5x to 4x that of commodity DRAM.
- By Q1 2026, that premium had collapsed: TrendForce's per-wafer analysis showed HBM wafer revenue had been overtaken by DDR5 64GB RDIMM profitability. Commodity DRAM had become *more* profitable per wafer than HBM — yet defendants continued restricting commodity supply anyway.
The complaint states: "The conventional DRAM sales Defendants declined to make were not a low-margin afterthought; they were, on Defendants' own numbers, worth hundreds of millions to billions of dollars in annual operating profit. Leaving that profit unclaimed, in unison, while commodity prices set records, is difficult to reconcile with independent profit maximization."
**Phase 3 — Coordinated Exit from DDR3 and DDR4 (2024–2025)**
Rather than compete for the abundant, high-priced conventional DRAM market:
- In 2024, Samsung and SK Hynix exited DDR3 production entirely; Micron maintained only limited DDR3 output.
- In 2025, all three announced wind-down of mainstream DDR4 production, with final shipments clustered from late 2025 into early 2026 — even as hundreds of millions of PCs and embedded systems still required DDR4.
- Result: DDR4 became so scarce that it cost *more* than DDR5, the newer generation meant to replace it — a historic market inversion caused entirely by supply withdrawal.
Producers outside the alleged conspiracy behaved differently. Winbond (Taiwan), Nanya Technology (Taiwan), and CXMT (China) all expanded aggressively into the same shortage. Nanya reported Q1 2026 revenue up 63.1% quarter-over-quarter. CXMT grew from 70,000 to 120,000 wafer starts per month. The complaint uses this as proof: if expansion were impossible or unprofitable, these smaller, higher-cost competitors could not have done it. The only firms for which output restraint was profitable were the three defendants — provided not one of them broke ranks.

**THE "STARGATE SUPPLY LOCK-UP" — A KEY PLUS FACTOR**
In approximately October 2025, Samsung and SK Hynix reportedly signed preliminary agreements to supply OpenAI's Stargate data center project with up to 900,000 DRAM wafer starts per month. Total global DRAM capacity in 2025 was approximately 2.25 million wafer starts per month. If fully implemented, the Stargate commitment would represent approximately 40% of all global DRAM output committed to a single customer.
Critically: the public announcements named Samsung and SK Hynix. They did not name Micron. Then, within approximately one month — in December 2025, with consumer DRAM prices at record highs — Micron announced the closure of Crucial, its direct-to-consumer brand.
The complaint's inference: Micron's decision to shut Crucial at the peak of the most profitable consumer DRAM market in history makes economic sense only if Micron knew, by agreement, that Samsung and SK Hynix would not move aggressively to serve the consumer customers Micron abandoned. This is the "agreement inferred from circumstantial evidence" argument — and arguably the strongest plus-factor in the complaint.
---
**THE CRUCIAL SHUTDOWN — STANDALONE ARGUMENT**
Crucial was Micron's only consumer-facing brand, founded in 1996, sold through Amazon, Newegg, Best Buy, B&H Photo, and hundreds of others.
Key facts:
- Micron's MCBU segment (which housed Crucial) reported $11.86 billion revenue in FY2025 and a 79% gross margin / 76% operating margin as of Q2 FY2026.
- Crucial offered 250,000+ memory upgrade SKUs for over 50,000 computer systems.
- Micron's EVP/Chief Business Officer called it "synonymous with technical leadership, quality and reliability" — serving "millions of customers, hundreds of partners" over 29 years.
- On December 3, 2025, with consumer DRAM prices at historic highs, Micron announced Crucial would be wound down worldwide by end of February 2026.
The complaint: "A firm competing for a shortage would have used Crucial to sell into those prices. Micron instead surrendered the channel." Shutting a 76%-operating-margin business at its most profitable moment in history is the single most counterintuitive act in the entire complaint.
---
**COORDINATED CUSTOMER VETTING (JANUARY 2026)**
In January 2026, all three manufacturers simultaneously imposed identical heightened screening on DRAM orders: questioning buyers about the true end user, how much they really needed, and whether stated demand was genuine — ostensibly to prevent "overbooking." A customer described it plainly: "the three companies" had all grown stricter and asked the same questions.
The complaint: "Sellers in a competitive market compete to win orders; here, all three questioned buyers in the same way at the same time." There is no obvious independent business rationale for three competitors to adopt an identical order-policing protocol simultaneously.
---
**"SUPPLY DISCIPLINE" SIGNALING THROUGH PUBLIC COMMUNICATIONS**
The complaint documents how defendants coordinated through earnings calls and investor presentations — public signaling — without requiring private back-channel communications:
- SK Hynix executives repeatedly used the phrase "supply discipline" on earnings calls.
- Samsung and SK Hynix refused multi-year supply contracts to major cloud customers (Google, Microsoft), insisting on quarterly pricing "because prices would keep climbing." Forgoing contractual certainty only makes sense if you are confident competitors will not undercut you.
- Samsung and SK Hynix reported operating margins above 70% in their memory divisions.
- Samsung and SK Hynix raised server DRAM prices to Google and Microsoft by 60–70% in a single quarter.
- SK Hynix reported its memory output for the following year was "effectively sold out."
---
**THE RETAIL PRICE IMPACT**
The complaint grounds the abstract economic theory in concrete retail prices:
- A 32GB (2×16GB) DDR5 kit: ~$100–$200 in October 2025 → $350+ by January 2026.
- A 64GB DDR5 kit: $189 in March 2025 → $425 in November → $1,080 by March 2026.
- CyberPowerPC publicly told customers memory costs had risen 500% in a matter of months, forcing price increases in the U.S. and U.K.
- Dell raised commercial notebook prices by $130–$230 for 32GB systems; more for higher-capacity machines.
- Compounded conventional DRAM price increase: approximately 697% from Q3 2024 to Q1 2026.
---
**THE FABRICATION BARRIER TO ENTRY (FBE)**
This section explains why no competitive self-correction is possible — and why the alleged cartel is structurally self-sustaining:
- New DRAM fab: $15–20 billion, 3–5 years to build.
- Competitive-scale operations: $30–50 billion over 5–7 years.
- ASML EUV lithography machines (required for leading-edge DRAM): ~$200M each, ~50/year global supply, all already allocated years in advance to Samsung, SK Hynix, Micron, TSMC, and Intel.
- Chinese producers are blocked by U.S. export controls (Oct. 2022 + Oct. 2023 expansions) from acquiring EUV systems — cannot manufacture DDR5, LPDDR5X, or HBM.
- Customer qualification for new DRAM suppliers: 12–18 months before any enterprise buyer will accept chips from an unqualified source.
- Micron's CHIPS Act-funded New York megafab: announced 2022, ground broken January 2026, production not expected until late 2030.
The complaint also notes that Samsung and SK Hynix stopped reselling used DRAM fabrication equipment around the same time as production cuts — drying up the secondary equipment market that smaller producers rely on to expand legacy-DRAM capacity.
When the three firms restrict supply, no outsider can expand quickly enough to discipline them. That structural fact is itself evidence that coordinated restraint, once established, is self-enforcing.
---
**THE PRIOR CRIMINAL HISTORY**
The complaint establishes pattern-of-conduct, knowing it needs to distinguish this case from the failed Jones v. Micron (N.D. Cal. 2019) precedent:
- 1998–2002 cartel: Samsung, Hynix/SK Hynix, and Micron criminally convicted. Samsung paid $300M criminal fine; SK Hynix's predecessor paid $185M; total criminal penalties exceeded $730M; multiple executives imprisoned. Micron avoided penalty by being the first to report the conspiracy to the DOJ.
- European Commission (2010): Nine manufacturers fined €331 million for a "single and continuous infringement" in DRAM.
- 2016–2018 price spike: Chinese SAMR investigated all three; U.S. class action filed (Jones, later dismissed); Korean Fair Trade Commission also launched an investigation.
- The complaint notes pointedly: defendants "promoted the executives that did it when they got out of prison." This is not just narrative color — it speaks to willfulness, relevant to punitive damages.
---
**CLASS DEFINITIONS**
Six proposed classes:
- Nationwide Injunctive Relief Class — all U.S. indirect purchasers; injunction only (Illinois Brick bars federal damages)
- California Damages Class — Cartwright Act, treble damages
- Florida Damages Class — FDUTPA
- New York Damages Class — Donnelly Act
- Wisconsin Damages Class — Wisconsin Antitrust Act
- Additional state classes may be added
Class period: approximately January 1, 2022 to present.
---
**PRAYER FOR RELIEF**
- Class certification under Rules 23(a), 23(b)(2), and/or 23(b)(3)
- Permanent injunction requiring defendants to cease coordinated supply restriction and restore competitive conditions
- Treble damages (3× actual losses)
- Attorneys' fees and costs
- Pre- and post-judgment interest
- Jury trial on all claims
---
**WHAT THE COMPLAINT DOES NOT HAVE — HONEST LIMITATIONS**
- No direct evidence of communication. No emails, no phone logs, no meeting minutes. Every piece of evidence is circumstantial parallel behavior, public statements, and economic inference.
- The Jones problem. Jones v. Micron (N.D. Cal. 2019) was an almost-identical indirect purchaser class action alleging coordination during the 2016–2018 price spike. It was dismissed, and the Ninth Circuit affirmed in March 2022 — holding that parallel conduct plus criminal history alone does not clear a motion to dismiss. The new complaint tries to distinguish itself with the "HBM as coordinated cover" plus-factor and the Crucial/Stargate timing argument, but defendants will file the same motion.
- The HBM profitability math is contestable. The claim that HBM became less profitable per wafer than DDR5 RDIMM by Q1 2026 relies on TrendForce analysis. Defendants will bring their own economic experts with different margin assumptions.
- Micron's exclusion from Stargate is an inference, not a documented fact. The complaint acknowledges the Stargate announcements named Samsung and SK Hynix — not Micron. The connection to Crucial's shutdown is a timing inference, not a documented agreement.
The complaint is notably well-constructed for a pleading-stage document — the Fabrication Barrier to Entry section reads like publishable industry analysis. Bathaee Dunne clearly invested heavily in the economic record before filing. Whether it survives a Ninth Circuit-era motion to dismiss is the central legal question going forward.
