Power2B v. Samsung: Federal Circuit Splits Decision on Computer Navigation Patent
Power2B, Inc. challenged Samsung Electronics over US7952570, covering computer navigation technology. The Federal Circuit issued a mixed ruling — affirming in part and reversing in part — after a 476-day appellate proceeding, leaving portions of the patentability determination intact while overturning others.
A Split Federal Circuit Ruling on Interactive Navigation Patent Validity
Power2B, Inc. brought this appeal before the U.S. Court of Appeals for the Federal Circuit (Case No. 24-1399) challenging a patentability determination related to US7952570B2, which covers computer navigation technology. The defendants, Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc., had successfully contested validity at the tribunal below. The appeal was filed on January 29, 2024 and closed on May 19, 2025, spanning 476 days.
The Federal Circuit issued a mixed disposition — affirming in part and reversing in part — meaning the appellate court found no reversible error in certain aspects of the lower patentability ruling but identified legal or factual error sufficient to overturn other aspects. Additionally, part of the appeal was dismissed, suggesting procedural deficiencies or jurisdictional issues narrowed the scope of merits review on at least one issue.
The split outcome is commercially significant: it suggests that at least some claims or grounds challenged by Samsung survived appellate scrutiny while others did not, potentially preserving a subset of Power2B’s patent rights. The precise claim-level breakdown and the basis for the partial reversal are not fully discernible from the public record alone, and the ultimate enforceability posture of US7952570 will depend on remand proceedings or further developments below.

Federal Circuit splits: what the affirmed-in-part, reversed-in-part ruling means
Affirmed-in-part, reversed-in-part: what this ruling means
An ‘affirmed-in-part, reversed-in-part’ disposition means the Federal Circuit found no reversible error in certain aspects of the lower decision — those portions stand — but identified sufficient legal or factual error to overturn other aspects. This is distinct from a blanket affirmance; the court conducted a granular review and reached different conclusions on different issues or claims. The partial dismissal further narrows the scope of what received a merits ruling.
Mixed appellate outcomePower2B recovers on some grounds but not all
For Power2B, the reversal-in-part is a partial victory: at least some claims or patentability grounds that were decided against them below have now been overturned by the Federal Circuit. However, the affirmance-in-part means other adverse findings remain intact. The net enforceability of US7952570 against Samsung and third parties depends on which specific claims or grounds were reversed and what relief follows on remand.
Partial patent recoverySamsung retains some wins, loses others on appeal
Samsung successfully defended the lower ruling in part — the affirmance-in-part preserves some of its invalidity findings. However, the reversal-in-part means Samsung’s challenge did not fully survive Federal Circuit review. Samsung may face renewed infringement exposure on the reversed claims, and the partial dismissal does not necessarily benefit either party on the merits of those issues.
Partial challenge upheldUncertainty persists for computer navigation IP landscape
A split Federal Circuit outcome on a computer navigation patent creates residual uncertainty for competitors and product teams operating in the interactive input and navigation space. The patent’s enforceability is neither fully extinguished nor fully confirmed, suggesting that third parties should monitor remand proceedings closely. Companies with products touching US7952570’s claim scope — particularly Samsung’s product lines — face a nuanced risk profile until the lower tribunal resolves outstanding issues.

Official order — verbatim text
The Federal Circuit’s disposition — ‘AFFIRMED-IN-PART AND REVERSED-IN-PART’ — reflects a nuanced appellate review in which the court applied de novo review to legal questions of patentability and substantial evidence review to underlying factual findings. The split outcome signals that the lower tribunal’s reasoning was sound on certain grounds but legally or factually deficient on others. Neither party achieved a clean result, and the practical import of the ruling turns on precisely which claims or issues fall on each side of the divide.
US7952570B2 — Computer Navigation and Interactive Input Technology
US7952570B2 (application number US11/006486) covers computer navigation technology — a domain encompassing interactive input, cursor control, and user interface navigation systems. The patent’s technology is relevant to how users interact with computing devices through physical gestures or input mechanisms, placing it at the intersection of hardware control and software interface design. Its application filing date provides context for assessing the competitive landscape at the time of invention and the prior art universe relevant to validity challenges.
From a strategic standpoint, a computer navigation patent asserted against Samsung — one of the world’s largest producers of smartphones, tablets, and smart displays — carries significant commercial weight. Samsung’s product lines span precisely the categories where interactive navigation IP is most contested. The Federal Circuit’s partial reversal suggests the patent retains meaningful claim coverage, making it a live consideration for any competitor shipping products with similar input or navigation architectures. Portfolio holders in adjacent spaces should assess their exposure against the surviving claims.
Should you run an FTO against US7952570B2?
Any company designing or shipping computer navigation products — including smartphones, tablets, interactive displays, or gesture-based input systems — should treat US7952570B2 as an active risk flag following this split Federal Circuit ruling. The partial reversal means claims that were previously considered invalidated may now be enforceable, and the precise scope of surviving claims should be assessed against your product architecture before further commercialisation.

What this case signals for the computer navigation IP landscape
A split Federal Circuit ruling on patentability rarely ends the story — it reshapes it. Here is what practitioners and product teams should take away.
Partial reversals at the Federal Circuit demand claim-level analysis
When the Federal Circuit affirms in part and reverses in part, the surviving and overturned portions are defined at the claim or issue level. Patent counsel monitoring US7952570 must map exactly which claims remain valid, which are invalidated, and which were not adjudicated. Generic FTO reliance on a split outcome is a material risk.
Partial dismissal signals a procedural threshold that narrowed review
The ‘appeal dismissed in part’ basis of termination suggests at least one issue did not clear an appellate procedural bar — finality, standing, or issue preservation. This is a reminder that Federal Circuit appeals require meticulous issue preservation at the PTAB or district court level, or those arguments are forfeited.
Power2B v Samsung — key questions answered
The Federal Circuit issued an affirmed-in-part and reversed-in-part decision in Case No. 24-1399, closing on May 19, 2025. The court upheld portions of the lower patentability ruling on US7952570B2 while overturning others, and part of the appeal was dismissed. The precise claim-level breakdown is not fully disclosed in the public docket summary.
US7952570B2 covers computer navigation technology, broadly encompassing interactive input and user interface control systems. Power2B asserted this patent against Samsung Electronics, a leading manufacturer of consumer devices in which navigation and input technologies are core functionality. The case proceeded as a patentability — invalidity/cancellation — dispute.
It means the Federal Circuit found the lower tribunal correct on some issues but wrong on others. For US7952570B2, some invalidity findings may stand while others have been overturned, potentially restoring enforceability for certain claims. The practical effect depends on which specific claims or grounds fall on each side — information typically clarified in the full opinion.
The basis of termination references ‘Appeal Dismissed in Part,’ which typically indicates a procedural or jurisdictional deficiency — such as failure to preserve an issue below, lack of standing on a specific claim, or an issue not ripe for appellate review. It does not reflect a merits determination on the dismissed portion. The precise reason would appear in the Federal Circuit’s opinion.
Following such a ruling, the case is typically remanded to the originating tribunal (e.g., PTAB or district court) for further proceedings consistent with the Federal Circuit’s guidance on the reversed issues. Remand may involve reconsideration of specific claims, additional evidence, or a new merits determination on the overturned grounds. Both parties may also seek en banc rehearing or certiorari on remaining issues.
