Case Overview
The Parties
⚖️ Plaintiff (Appellate)
One of the world’s largest consumer electronics manufacturers, with an extensive global patent portfolio. As plaintiff at the appellate level, Samsung pursued an invalidity and cancellation challenge against Neonode’s patent rights.
🛡️ Defendant (Appellate)
A patent assertion entity focused on mobile interface technology, whose assertion strategy centers on foundational touchscreen and mobile UI patents.
The Patent at Issue
This landmark case involved **U.S. Patent No. 8,095,879 B2** (Application No. US10/315250), covering a user interface for mobile handheld computer units — technology that sits at the heart of modern smartphone interaction design. This patent protects innovations in how users interact with mobile devices.

The Verdict & Legal Analysis
Outcome
The Federal Circuit issued a decisive ruling: **AFFIRMED.** The appellate court upheld the prior determination sustaining **U.S. Patent No. 8,095,879 B2**, effectively rejecting Samsung’s invalidity and cancellation arguments. The patent remains valid and enforceable. No damages figures were disclosed in the available case record, consistent with the procedural posture of a patentability-focused appeal rather than an infringement damages proceeding.
Key Legal Issues
The Federal Circuit’s analysis likely focused on critical invalidity issues such as anticipation (35 U.S.C. § 102) or obviousness (35 U.S.C. § 103), and potentially written description and enablement (35 U.S.C. § 112). By affirming, the Federal Circuit signaled that the ‘879 patent’s claims withstood these challenges — a meaningful validation of Neonode’s prosecution strategy and claim drafting for this mobile UI technology.
