Case Overview
The Parties
⚖️ Plaintiff
Patent assertion entity (“PAE”) with an IP portfolio focused on semiconductor interconnect technologies — specifically NoC and SoC designs.
🛡️ Defendant
Chinese consumer electronics manufacturer known globally for its Android smartphones, incorporating third-party SoC solutions.
The Patents at Issue
NST asserted six U.S. patents, all directed to Network-on-Chip (NoC) interconnect and System-on-Chip (SoC) architecture innovations. These patents collectively cover communication architectures within multi-processor integrated circuits, technology embedded in essentially every modern high-performance chip.
- • US7594052B2
- • US7373449B2
- • US7366818B2
- • US7769893B2
- • US8702893B2
- • US8086800B2

The Verdict & Legal Analysis
Outcome
On July 15, 2024, Chief Judge Rodney Gilstrap granted the parties’ Joint Motion to Dismiss all claims without prejudice. No damages award, injunction, or judicial finding on the merits of infringement or validity was issued. Each party was ordered to bear its own attorneys’ fees, costs, and expenses.
Key Legal Issues
Because the case resolved via joint dismissal before any substantive court rulings, no public judicial analysis of infringement, claim construction, or patent validity is available. The absence of a Markman hearing ruling or summary judgment decision means the legal strength of NST’s six patents — and OnePlus’s anticipated defenses — was never adjudicated publicly.
The breadth of accused products, encompassing both component-level (Qualcomm, Samsung Exynos, TI chips) and system-level (Audi, Ford, Volkswagen platforms) defendants, suggests NST pursued a comprehensive infringement theory targeting the NoC/SoC architecture across the supply chain. This multi-tier assertion strategy is a recognized approach by PAEs to maximize licensing leverage.

NST asserted six U.S. patents — US7594052B2, US7373449B2, US7366818B2, US7769893B2, US8702893B2, and US8086800B2 — all directed to network-on-chip and system-on-chip interconnect architectures.
The parties filed a joint motion representing that all claims were resolved. The court granted dismissal without prejudice, with each party bearing its own costs — consistent with a confidential settlement or licensing agreement.
It reinforces that foundational chip architecture patents carry significant assertion value in the Eastern District of Texas, and that broad supply-chain infringement theories can accelerate pre-trial licensing resolution.
