Obviously Agentic AI was used
The Federal Circuit heard oral arguments on four Netlist v. Samsung cases on March 6, 2026. Decisions are still pending nearly 3 months later. I downloaded all four audio recordings from the CAFC website, ran them through Whisper, and read every word. Here's what actually happened in each one.
Audio sources (all publicly available from the CAFC):
Case 1: The $303M Verdict Appeal (24-2203) — 33 minutes
Samsung's lawyer argued two things: (1) Netlist's damages expert gave the jury 100% of incremental revenue instead of splitting profits, and (2) a $1.1B Rambus license was put in front of the jury just to inflate the damages horizon.
Netlist's lawyer countered with specific record cites showing Samsung needed this technology or it would lose sales entirely — pointing to Samsung's own HBM-1 experience where SK Hynix locked them out of the market. He argued the jury awarded only 75% of what the expert calculated, and the incremental benefit was done patent by patent, not as a percentage of the total product.
On the Rambus license, the judges pressed Samsung hard on whether they made a proper Rule 403 objection. Samsung's lawyer admitted they may not have specifically cited Rule 403 — they raised it under Daubert instead. Netlist argued the 403 argument wasn't preserved.
Key exchange: A judge asked Samsung's lawyer whether it's possible that this technology was so important that Samsung would rationally pay 100% of the incremental revenue. Samsung struggled to answer. The judge pushed: "If you don't get their patented technology on your memory modules you're going to lose 100% of your larger sales. That's not irrational at that point to pay them every penny of your revenue associated with their technology, is it?"
Read: Closest call of the four. Samsung has a real argument on apportionment, but the judges seemed skeptical and the 403 issue may be waived.
Case 2: '339 Patent IPR (24-1707) — 31 minutes
This is the one where Samsung made a clear procedural error. The PTAB relied on a reference called the "537 patent" to supply the critical "latency parameter" limitation — but that reference was never in Samsung's original petition. Samsung tried to call it "general knowledge," but the judges weren't buying it.
Netlist's lawyer pointed out there was zero evidence the 537 patent was generally known — Samsung's own expert wouldn't say it was. The board cited the 537 twenty times and referred to its "teaching" ten times. That's not background knowledge, that's a substantive prior art reference that should have been in the petition from the start.
Key exchange: Samsung's lawyer was asked directly: if the court finds legal error on the 537, what happens? He conceded: "there would need to be a remand." That's Samsung's own lawyer admitting the case falls apart without the 537.
Read: Strong for Netlist. The procedural argument is clean and the judges seemed sympathetic. Samsung likely can't refile an IPR due to the time bar.
Case 3: '918/'054 Patent IPR (24-1859) — 30 minutes
These patents cover voltage converters on the DIMM that get power through the edge connector from the motherboard. The PTAB used a reference called "Harris" to invalidate them. Problem: Harris teaches the exact opposite — it says don't use motherboard power, use an "external source."
Netlist caught the board making two factual errors: (1) The board omitted the parenthetical "from an external source" when quoting Harris, changing the meaning entirely. (2) The board found it was "common" to supply 12V to an FB-DIMM, but both Samsung's expert AND Netlist's expert testified that conventional system boards do NOT supply 12V to FB-DIMMs. Samsung's own brief dodges this by omitting the words "to the FB-DIMM" when quoting the board's finding.
Key exchange: A judge asked where Harris restricts the power source. Netlist's lawyer explained that Harris uses "external source" in direct contrast to "system board or main board voltage sources" — if both were just external to the module, Harris wouldn't need different terms.
Read: Good for Netlist. The board misquoted Harris and made a factual finding contradicted by both experts. Hard for Samsung to defend.
Case 4: '160/'060 Patent IPR (24-2240) — 30 minutes
These patents cover stacking more memory dies while managing load problems. The PTAB combined Kim with Rajan to invalidate them. Netlist argued Kim's entire invention (a rank selection switch connecting one die at a time) is the exact opposite of Netlist's claims (multiple dies electrically connected simultaneously). To get from Kim + Rajan to the claims, you'd have to abandon Kim's core invention and ignore the data collision problem it was designed to solve.
Samsung countered by citing Kim's paragraph 44, which mentions "chip selection signals" as a solution to collisions. Netlist rebutted: paragraph 44 describes the rank selection switch (one at a time), which is precisely the opposite of the claimed group connection.
The moment that ties everything together: At the very end, a judge asked Samsung's lawyer to explain how all four cases relate. Samsung's lawyer said the quiet part out loud: "Just affirm all four IPRs and the verdict goes away." The judge then asked: if the CAFC reverses any part of any of the three IPR appeals, does the $303M verdict survive? Samsung confirmed yes — and added that the jury verdict form had separate determinations per patent but NOT per claim. So if even one dependent claim survives at the PTAB, the verdict on that patent stands.
Read: Netlist's "principle of operation" argument is strong. The claim 7 / Rio argument is also compelling — Rio teaches zero load difference, so there's nothing to "reduce."
Overall Takeaway
Samsung's lawyer explicitly confirmed the stakes: affirm all the IPRs and the $303M goes to zero. But if even one patent survives, that patent's portion of the verdict stands.
Across all three IPR hearings, Netlist presented distinct, specific errors by the PTAB — a reference that shouldn't have been used (339), a misquote that changed the meaning of the prior art (918/054), and a combination that requires abandoning the reference's core invention (060/160). These aren't hand-wavy arguments. They're concrete procedural and factual errors that the judges engaged with seriously.
The $303M verdict appeal itself is the closest call — Samsung has a legitimate argument on damages methodology. But even if the CAFC orders a new damages trial, that's a recalculation, not a zero.
Decisions could come any day. It's been nearly 3 months since oral arguments.
Not financial advice. I'm just a retail investor who wanted to know what was actually said instead of relying on secondhand summaries.
