Aperçu du dossier
Les parties
⚖️ Demandeur
A patent assertion entity (PAE) focused on licensing and litigation, holding intellectual property rights in semiconductor processing innovations.
🛡️ Défendeur
One of the world’s largest semiconductor manufacturers, with extensive R&D investment in processor architecture and advanced packaging technologies.
Le brevet en cause
This case centered on a patent covering reconfigurable processor modules comprising hybrid stacked integrated circuit die elements — technology directly relevant to advanced chip design and heterogeneous computing architectures. The patent claimed innovations in how multiple processor die components are physically stacked and configured within an integrated circuit module.
- • US 7,282,951B2 — Reconfigurable processor modules; hybrid stacked integrated circuit die elements

Le verdict et l'analyse juridique
Résultat
The Court of Appeals for the Federal Circuit **affirmed** the lower tribunal’s finding of **unpatentability**, resulting in the **invalidity and cancellation** of U.S. Patent No. 7,282,951B2. No damages were awarded, as the affirmance of unpatentability effectively extinguished Arbor Global’s ability to assert the patent.
Principales questions juridiques
The Federal Circuit upheld a determination that the claims of the ‘951 patent failed to satisfy the legal requirements for patentability under U.S. patent law. This finding most commonly arises from challenges under 35 U.S.C. § 102 (anticipation) or 35 U.S.C. § 103 (obviousness). The verdict cause is classified as an Invalidity/Cancellation Action, confirming that Samsung’s defense strategy successfully attacked the foundational validity of the asserted patent rather than contesting infringement on the merits. This outcome underscores the elevated scrutiny that complex processor architecture patents face during post-grant validity proceedings and appellate review.

The dispute centered on U.S. Patent No. 7,282,951B2 (Application No. 11/383,149), covering a reconfigurable processor module comprising hybrid stacked integrated circuit die elements.
The Federal Circuit affirmed a finding of unpatentability — an invalidity/cancellation action — resulting in the cancellation of the asserted patent. The case was closed July 16, 2024.
The outcome reinforces the effectiveness of post-grant USPTO proceedings (IPR) as a defense strategy against NPE assertions of semiconductor architecture patents, and signals Federal Circuit willingness to affirm unpatentability findings in prior-art-dense technology areas.
