Realtek v. AMD: ITC Section 337 Complaint Rejected in 37 Days
Realtek Semiconductor filed a Section 337 complaint at the US International Trade Commission against Advanced Micro Devices, asserting three semiconductor patents covering power mesh design, inductor-capacitor resonant circuits, and spiral inductor structures. The ITC rejected the complaint at institution, closing the investigation in just 37 days — before any substantive merits review.
ITC Rejects Realtek’s Section 337 Complaint Against AMD at Institution
On 20 August 2024, Realtek Semiconductor Corp. filed a Section 337 complaint at the United States International Trade Commission against Advanced Micro Devices, Inc. (AMD), asserting infringement of three US patents: US8006218B2 (power mesh arrangement in multi-domain integrated circuits), US9590582B2 (semiconductor device with inductor-capacitor resonant circuit), and US7936245B2 (stacked spiral inductor structure). The complaint was filed before Administrative Law Judge Cameron Elliot in Washington, D.C.
The ITC rejected the complaint on 26 September 2024 — just 37 days after filing — on the basis of ‘Case Rejected,’ meaning the Commission declined to institute a formal investigation. This is a pre-institution termination: the ITC found the complaint did not satisfy the threshold requirements to open a full Section 337 investigation, and the case was closed without any finding of infringement or validity ruling on the asserted patents.
A 37-day lifecycle is notably short even by ITC standards, where pre-institution rejections typically reflect procedural or standing deficiencies in the complaint rather than a merits judgment. The public record does not disclose the specific grounds for rejection, which could include failure to demonstrate a domestic industry, inadequate identification of accused products, or jurisdictional deficiencies. AMD’s counsel at Winston & Strawn secured a swift closure before any discovery or claim construction proceedings commenced.

Case rejected at institution: what this pre-institution termination means
ITC pre-institution rejection: no investigation opened
A Section 337 complaint must satisfy threshold requirements before the ITC institutes a formal investigation. ‘Case Rejected’ indicates the Commission found the complaint deficient at this gatekeeping stage — possible grounds include failure to establish a domestic industry, insufficient identification of accused products or articles, or procedural non-compliance. No merits ruling on infringement or patent validity was made.
Pre-institution terminationRealtek’s patents remain untested — and re-filing remains possible
A pre-institution rejection does not invalidate Realtek’s patents nor constitute a finding of non-infringement. The three asserted patents — US8006218B2, US9590582B2, and US7936245B2 — retain their legal presumption of validity. Realtek could cure deficiencies and re-file at the ITC, or pursue infringement claims in US district court. However, the swift rejection suggests a material deficiency in how the complaint was structured.
Patents remain enforceableAMD avoids ITC proceedings entirely — no exclusion order risk at this stage
AMD secured termination before any formal investigation commenced, avoiding the burdensome discovery, claim construction briefing, and potential exclusion order exposure that characterise a full ITC proceeding. Winston & Strawn’s early exit strategy is consistent with challenging the sufficiency of the complaint at the institution stage — a lower-cost, high-reward defence posture. AMD’s product imports face no current ITC restrictions from this action.
No exclusion order issuedSector signal: ITC gatekeeping tightens for semiconductor IP complaints
This rejection reinforces that the ITC’s institution review is a substantive hurdle, not a formality — particularly for semiconductor IP where domestic industry requirements can be difficult to establish for fabless design companies. For semiconductor IP holders targeting imported chips, the case suggests meticulous pre-filing preparation on domestic industry evidence is critical. AMD’s product roadmap faces no immediate import restriction from this action.

Official order — verbatim text
The ITC’s ‘Participant Disposition: Denied’ on the basis of ‘Case Rejected’ reflects a pre-institution termination — the Commission’s administrative finding that the complaint failed to meet the threshold requirements for opening a formal Section 337 investigation. Critically, this is not a merits ruling: no finding of infringement, non-infringement, or invalidity was made with respect to US8006218B2, US9590582B2, or US7936245B2. The phrasing is consistent with a deficiency in complaint form or substance identified during the ITC’s 30-day institution review window, and does not preclude Realtek from re-filing a corrected complaint or pursuing these patents in an alternative forum.
US8006218B2, US9590582B2 & US7936245B2 — Semiconductor Power & Inductor IP
The three asserted patents span interconnected layers of semiconductor IC architecture. US8006218B2 (App. No. 12/271534) covers power mesh arrangement methods in integrated circuits with multiple power domains — a foundational concern in modern SoC power management. US9590582B2 (App. No. 14/338904) protects semiconductor devices incorporating inductor-capacitor (LC) resonant circuits, relevant to RF and clock generation blocks. US7936245B2 (App. No. 12/773024) covers stacked spiral inductor structures — a critical passive component architecture in RF-integrated semiconductor devices.
These patents collectively address physical and circuit-level innovations in high-density integrated circuit design — areas directly implicated in AMD’s GPU, APU, and high-performance computing silicon. Power mesh architecture and on-chip inductor design are embedded in virtually every modern multi-domain processor. Realtek’s decision to assert these patents at the ITC against AMD suggests a view that AMD’s imported chips incorporate these specific structural arrangements, though the pre-institution rejection means this allegation was never tested on the merits.
Should you run an FTO against US8006218B2, US9590582B2, and US7936245B2?
Any company designing or importing integrated circuits with multiple power domains, on-chip LC resonant tanks, or stacked spiral inductors should treat these three Realtek patents as active FTO considerations. The pre-institution rejection in this case did not narrow or invalidate any claims — meaning the full scope of each patent’s claims remains legally intact and enforceable. Fabless designers, OSAT firms, and SoC integrators shipping into the US market are particularly exposed given the ITC’s import-blocking jurisdiction.

What this case signals for the semiconductor IC IP landscape
Realtek’s swift ITC rejection highlights key risks for fabless semiconductor companies pursuing Section 337 exclusion strategies against US chip designers.
ITC institution is a real gatekeeping hurdle for fabless semiconductor complainants
Fabless companies like Realtek face structural challenges satisfying the ITC’s domestic industry requirement, which demands significant US-based investment in articles covered by the asserted patents. A pre-institution rejection in 37 days suggests the complaint may have lacked sufficient domestic industry evidence — the single most common reason the ITC declines to institute semiconductor-related Section 337 investigations.
AMD’s early termination strategy avoided the costliest phase of ITC litigation
Full ITC investigations routinely cost defendants $5–15M and involve parallel exclusion order risk at the border. By securing rejection at institution, AMD’s counsel avoided discovery, claim construction, and evidentiary hearings entirely. For defendants in Section 337 proceedings, early challenge of complaint sufficiency — particularly domestic industry standing — can deliver disproportionate early closure.
Realtek v Advanced — key questions answered
The ITC closed Investigation 337-TA-1350 on the basis of ‘Case Rejected’ just 37 days after filing. The public record does not specify the exact grounds, but pre-institution rejections at the ITC typically arise from failure to satisfy the domestic industry requirement, procedural deficiencies in the complaint, or inadequate identification of accused imported articles. No merits finding on the three asserted patents was made.
Realtek asserted three US patents: US8006218B2 covering a power mesh arrangement method in multi-power-domain integrated circuits, US9590582B2 covering a semiconductor device with an inductor-capacitor resonant circuit, and US7936245B2 covering a stacked spiral inductor structure. All three patents remain in force and were not invalidated by this proceeding.
A pre-institution rejection does not bar Realtek from re-filing a Section 337 complaint with a corrected or more fully supported complaint, provided it addresses the deficiencies identified by the ITC. Realtek also retains the option to assert US8006218B2, US9590582B2, and US7936245B2 in US federal district court, where the ITC’s domestic industry threshold does not apply in the same form.
The ITC has a statutory 30-day window following filing to decide whether to institute a formal investigation. A closure at 37 days is consistent with a rejection at or shortly after this institution decision point — meaning the case ended before any investigation formally opened. This is significantly faster than the typical 16–18 month timeline for a full ITC Section 337 investigation, and indicates the matter was resolved entirely at the pre-institution administrative stage.
