Case Overview
The Parties
⚖️ Plaintiff
Non-practicing entity (NPE) that acquired a portfolio of semiconductor-related patents, many originating from legacy Freescale Semiconductor intellectual property.
🛡️ Defendant
World’s largest semiconductor manufacturer by revenue and the designer of the accused microprocessor products at issue.
Patents at Issue
This landmark case involved eight patents covering core aspects of modern processor architecture — areas directly relevant to competitive performance in Intel’s product lines.
- • US7706207B2 — Memory access and interconnect technologies
- • US8004922B2 — Semiconductor power/performance optimization (ultimately invalidated)
- • US8020014B2 — Process integration for semiconductor devices
- • US7268588B2 — Transistor and circuit design
- • US7675806B2 — Semiconductor architecture
- • US7709303B2 — Chip design methodology
- • US8268672B2 — Advanced manufacturing processes
- • US8566836B2 — Memory/storage controller technology (non-infringed)

The Verdict & Legal Analysis
Outcome
The court entered a mixed judgment on March 29, 2024. Specifically, in favor of Intel, VLSI’s infringement counts for US8004922 and US8566836 were dismissed, and US8004922 was declared invalid. Simultaneously, Intel’s counterclaim for a declaratory judgment of license was dismissed without prejudice, directing Intel to refile in the proper forum.
Key Legal Issues
The court’s summary judgment rulings drove the final disposition. The invalidation of US8,004,922 underscored the continuing viability of validity challenges on technical grounds. The non-infringement finding on US8,566,836 likely resulted from narrow claim construction. Intel’s failed license defense, dismissed on procedural grounds, reveals a crucial strategic dynamic as it leaves this defense live for potential future proceedings.

Eight U.S. patents covering semiconductor architecture, power management, memory control, and manufacturing processes, including US7706207, US8004922, US8020014, US7268588, US7675806, US7709303, US8268672, and US8566836.
The court entered summary judgment findings: US8004922 was found invalid, US8566836 was found not infringed, and Intel’s license counterclaim was dismissed without prejudice for improper forum.
It reinforces the viability of invalidity and non-infringement defenses at summary judgment in complex chip cases, while leaving Intel’s license defense unresolved — a key variable for VLSI’s broader assertion campaign.
