Samsung v. POWER2B (Fed. Cir. 23-1745): Split Ruling on Display Patent
Samsung Electronics and its U.S. subsidiary challenged the validity of POWER2B’s US8624850B2, a patent covering displays and information input devices, at the Federal Circuit. After 719 days, the court issued a mixed decision — affirming some grounds, reversing others, and remanding — leaving the patent’s ultimate fate unresolved.
Federal Circuit splits the difference on POWER2B display patent validity
Filed on 12 April 2023, Case No. 23-1745 is a Federal Circuit appeal brought by Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc. against POWER2B, INC., challenging the patentability of US8624850B2 — a patent directed to displays and information input devices. The appeal follows an invalidity or cancellation action at a lower tribunal, most likely an inter partes review proceeding before the USPTO Patent Trial and Appeal Board, consistent with the patentability verdict cause and the Federal Circuit’s appellate jurisdiction over such matters.
On 31 March 2025, the Federal Circuit issued a split decision: affirming the lower tribunal on some claim-level patentability grounds, reversing on others, and vacating and remanding the remainder for further proceedings. This fractured outcome means that neither Samsung nor POWER2B achieved a clean victory — certain claims or grounds survived Samsung’s challenge, others were invalidated, and a further subset must be reconsidered below.
A 719-day duration at the Federal Circuit suggests a substantively complex record, potentially involving multiple patent claims with distinct prior art analyses. The remand component is particularly significant: it extends commercial uncertainty for both parties and reopens licensing or design-around decisions that may have been anticipated on the merits. The precise scope of which claims were affirmed, reversed, or remanded is not determinable from the public record available here, and practitioners should consult the full opinion for claim-by-claim mapping.

Federal Circuit’s split ruling: what affirmed, reversed, and remanded means
What ‘affirmed-in-part, reversed-in-part, vacated and remanded’ means
A split Federal Circuit ruling is not a binary win or loss. ‘Affirmed-in-part’ means the court found no reversible error in specific portions of the tribunal’s ruling below. ‘Reversed-in-part’ signals that the court found legal or factual error on other grounds, overturning those findings. ‘Vacated and remanded’ nullifies the remaining portions and returns them to the lower tribunal for reconsideration under the Federal Circuit’s guidance.
Partial affirmance + remandPOWER2B retains partial protection — but remand keeps uncertainty alive
For POWER2B, the affirmed-in-part ruling preserves enforceability on at least some claims of US8624850B2, which Samsung failed to invalidate on appeal. However, the reversed portions represent a concrete loss of claim scope, and the remand reopens proceedings that could further narrow or eliminate additional claims. The patent cannot be characterised as fully upheld until remand proceedings conclude.
Partial survival — remand pendingSamsung wins reversal on some grounds, but the patent is not fully cancelled
Samsung secured reversals on at least some patentability grounds, achieving invalidation of a portion of POWER2B’s claim set. The remand offers a further opportunity to invalidate contested claims at the lower tribunal. However, the affirmed portions represent claims Samsung could not defeat — those survive and may continue to present infringement risk for Samsung’s display and input device product lines unless design-around measures are in place.
Partial win — further proceedings requiredSplit ruling signals continued IP risk for the display technology sector
A mixed Federal Circuit outcome on display and input device patents creates prolonged uncertainty for manufacturers operating in this space. Surviving claims retain full enforceability and — with the Federal Circuit’s partial affirmance — now carry stronger presumptive validity. Competitors and licensees in interactive display technology should monitor remand proceedings closely, as the final claim scope will directly affect freedom-to-operate positions and any pending licensing negotiations.

Official order — verbatim text
The Federal Circuit’s verdict of ‘AFFIRMED-IN-PART, REVERSED-IN-PART, VACATED AND REMANDED’ reflects a claim-by-claim or issue-by-issue appellate review of the lower tribunal’s patentability determinations regarding US8624850B2. Applying de novo review to legal questions (such as claim construction) and substantial evidence review to factual findings (such as prior art determinations), the court reached different conclusions across distinct grounds. The vacatur and remand component indicates that at least some issues could not be resolved on the existing record and require further fact-finding or reconsideration below. Neither party achieved a dispositive outcome.
US8624850B2 — Displays and Information Input Devices
US8624850B2 (application number US12/531031) covers displays and information input devices — a technology domain encompassing interactive touch interfaces, display-integrated input mechanisms, and related human-computer interaction hardware. The patent’s application number series is consistent with a mid-to-late 2000s filing window, placing its priority date during a period of rapid innovation in capacitive touch and display-integrated input technology. POWER2B, INC. holds this patent as a core asset.
For large-scale consumer electronics manufacturers such as Samsung, patents covering display and information input device architectures sit at the core of flagship product lines — including smartphones, tablets, monitors, and smart home devices. A patent of this character asserted against Samsung suggests POWER2B believed its claims read on commercially significant Samsung products. Even with partial claims reversed, the surviving claim scope may cover design elements broadly deployed across the display technology industry, making this patent strategically relevant beyond Samsung alone.
Should your team run an FTO against US8624850B2?
Any company developing, manufacturing, or commercialising products in the interactive display or touch-input device space — particularly those competing with or supplying to Samsung-type consumer electronics product lines — should treat US8624850B2 as a live FTO concern. The Federal Circuit’s partial affirmance confirms that at least some claims remain valid and enforceable. Until the remand proceedings conclude and a final claim scope is published, the risk perimeter of this patent is not fully defined.
PatSnap Eureka’s FTO Search Agent can map the surviving claim language of US8624850B2 against your product specifications, flag design elements that may fall within affirmed claim scope, and monitor the remand docket for updates. For R&D teams working on next-generation display or input device architectures, running a targeted Eureka FTO analysis now — before the remand outcome crystallises the enforceable claim set — is the lower-risk strategic posture.

What this case signals for the display technology IP landscape
A Federal Circuit split on display patent validity has lasting consequences for Samsung’s product portfolio and for how POWER2B can enforce its surviving claims.
Affirmed claims carry heightened presumptive validity post-appeal
Claims of US8624850B2 that survived Samsung’s Federal Circuit challenge now carry a reinforced validity presumption. Any future challenger — whether in district court or a new IPR — faces the elevated burden of clear and convincing evidence, with the Federal Circuit’s affirmance as additional precedential weight. Competitors in the display and input device space should reassess their IP exposure accordingly.
Remand extends design-around and licensing uncertainty for display makers
Until remand proceedings conclude and a final claim scope is established, manufacturers cannot rely on a definitive FTO analysis for technologies potentially covered by US8624850B2. Companies designing interactive display or touch-input products should treat the remanded claims as live risk and consider provisional design-around strategies or opening licensing discussions before the lower tribunal issues its remand decision.
Samsung v POWER2B — key questions answered
The Federal Circuit issued a split decision on 31 March 2025: affirmed-in-part, reversed-in-part, vacated and remanded. This means the court upheld some patentability findings for US8624850B2, reversed others in Samsung’s favour, and sent the remaining issues back to the lower tribunal for further proceedings. Neither party achieved a complete win.
The patent at issue is US8624850B2, filed under application number US12/531031, owned by POWER2B, INC. It covers displays and information input devices — technology relevant to interactive touch and display-integrated input products. Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc. challenged its patentability in what is consistent with an inter partes review appeal.
In appellate practice, ‘vacated and remanded’ means the Federal Circuit nullified specific portions of the lower tribunal’s decision and directed that those issues be reconsidered from scratch under guidance provided in the appellate opinion. For US8624850B2, this means that a subset of claim-level patentability findings are not final — they must be re-evaluated by the lower tribunal, extending the proceedings and leaving the ultimate validity of those claims unresolved.
The reversed portion of the ruling means that certain claims or grounds on which POWER2B prevailed below were found legally or factually deficient by the Federal Circuit. Those reversed findings reduce the enforceable claim scope of US8624850B2. However, the affirmed portions remain fully enforceable, and the remanded issues are still live. POWER2B can enforce surviving affirmed claims but must await the remand outcome before knowing the full contours of its patent.
Yes. The remand in Case 23-1745 will determine the final validity of a subset of claims in US8624850B2 — a patent covering displays and information input devices. Any company developing products in this space, or considering licensing discussions with POWER2B, should track the remand docket. The outcome will define the patent’s enforceable scope and directly affect freedom-to-operate positions across the interactive display industry.
