Amatech v. Infineon: Smart Card Patent Appeal Voluntarily Dismissed
Amatech Group Ltd. appealed a patentability ruling against Infineon Technologies AG at the Federal Circuit over US9033250B2, covering dual interface smart card manufacturing. The appeal was voluntarily dismissed after just 146 days, with each side bearing its own costs — leaving the underlying validity question unresolved on the merits.
A smart card patent appeal dropped before Federal Circuit merits review
Amatech Group Ltd., an Irish smart card technology company and holder of US9033250B2, filed this appeal at the Court of Appeals for the Federal Circuit on 13 September 2023. The appeal followed an underlying invalidity or cancellation action concerning the patentability of dual interface smart card manufacturing methods. Infineon Technologies AG, a major German semiconductor and smart card IC supplier, was the named respondent.
On 6 February 2024 — 146 days after filing — Amatech voluntarily dismissed the appeals pursuant to Federal Rule of Appellate Procedure 42(b). The court ordered that each side bear its own costs. Because the dismissal was voluntary and the order does not specify whether it was with or without prejudice, the public record is silent on that distinction. No merits ruling was issued, leaving the underlying patentability question formally unresolved at the Federal Circuit level.
The rapid resolution — well under six months — is notable for a Federal Circuit appeal, and typically suggests the parties reached some form of accommodation or that Amatech assessed the prospects of reversal as unfavourable. The absence of any cost award to either party is consistent with a negotiated or pragmatic exit. What drove Amatech’s decision to withdraw, and the current enforceability status of US9033250B2, cannot be determined from the public record alone.
Filing to Voluntary dismissal in 146 days
146-day appeal — resolved faster than the typical Federal Circuit disposition timeline
Appeal voluntarily dismissed: what the FRAP 42(b) exit means for both parties
FRAP 42(b) voluntary dismissal: no merits adjudication
Federal Rule of Appellate Procedure 42(b) allows an appellant to voluntarily dismiss an appeal, typically by motion. The court granted Amatech’s motion here. Crucially, this is a procedural exit — the Federal Circuit issued no ruling on the merits of the patentability dispute. The validity of US9033250B2 was neither confirmed nor invalidated at this appellate stage.
Procedural dismissal — no merits rulingWith or without prejudice? The public record does not say
A voluntary dismissal can be entered with or without prejudice, which has significant consequences: dismissal without prejudice could theoretically preserve future appellate options, while dismissal with prejudice forecloses them. The court’s order simply states ‘these appeals are dismissed’ without specifying either condition. Until further public filings clarify the terms, practitioners should treat the prejudice status as unknown.
Prejudice status unconfirmedAmatech exits without a Federal Circuit ruling in its favour
By voluntarily dismissing, Amatech forgoes any chance of obtaining a Federal Circuit reversal of the underlying patentability decision. This outcome typically signals either a commercial settlement, a licensing resolution, or a reassessment of litigation economics. The underlying invalidity or cancellation finding — if adverse to Amatech — may remain in effect depending on the proceeding below.
No appellate vindication for patent holderDual interface smart card IP remains in play for the sector
US9033250B2 covers methods of manufacturing dual interface smart cards — a technology central to payment, identity, and transit applications. With no Federal Circuit merits ruling, competitors and licensees cannot rely on this appeal to assess the patent’s enforceability. Companies operating in the dual interface smart card manufacturing space should independently monitor the underlying PTAB or district court record for the current validity status of this patent.

Official order — verbatim text
The Federal Circuit’s order is strictly procedural: it grants Amatech’s FRAP 42(b) motion and allocates costs neutrally, but makes no finding on patentability, claim validity, or the merits of the underlying cancellation action. The phrasing ‘these appeals are dismissed’ without prejudice specification leaves the door open to interpretive debate. For practitioners, the operative takeaway is that no binding Federal Circuit precedent on US9033250B2 was created by this proceeding.
US9033250B2 — Dual Interface Smart Card Manufacturing Methods
US9033250B2, filed under application number US14/020884, protects methods and structures relating to the manufacture of dual interface smart cards — cards capable of both contact and contactless communication. This technology underpins payment cards, identity documents, and transit passes that comply with ISO/IEC 14443 and ISO/IEC 7816 standards. The patent’s claims likely address inlay architecture, antenna integration, and lamination processes that enable reliable dual-mode operation in a standard card form factor.
Dual interface smart card manufacturing is a high-volume, technically demanding field where process patents carry significant commercial weight. Infineon Technologies is a dominant supplier of the semiconductor chips embedded in these cards, making any patent covering manufacturing methods directly relevant to Infineon’s customer ecosystem. For card manufacturers, module integrators, and inlay producers, the enforceability of US9033250B2 post-dismissal represents a live risk that warrants ongoing monitoring, particularly given that no Federal Circuit merits ruling was issued.
Should your team run an FTO against US9033250B2?
Any company designing, manufacturing, or supplying dual interface smart card inlays, laminates, or modules should assess exposure to US9033250B2. The voluntary dismissal of this Federal Circuit appeal does not resolve the patent’s validity or enforceability — it may still be asserted in district court or international proceedings. Card manufacturers, semiconductor module suppliers, and EMS providers working in the payment, identity, or transit card sectors face the most direct risk.

What this case signals for the smart card manufacturing IP landscape
A fast voluntary dismissal at the Federal Circuit in a patentability appeal rarely signals strength — and raises pointed questions for smart card sector IP strategy.
Voluntary Federal Circuit dismissals often signal behind-the-scenes resolution
When an appellant drops an appeal 146 days in without a merits ruling, it typically suggests a commercial or licensing resolution occurred off the public record. Smart card IP teams monitoring competitor portfolios should treat this case as a potential signal of licensing activity between Amatech and Infineon, even though no settlement terms are publicly confirmed.
No cost award cuts both ways — neither party claimed a clear win
The court’s mutual cost-bearing order is consistent with a negotiated exit rather than a capitulation. In fee-shifting contexts, prevailing parties often seek costs; the absence of any such motion here suggests both sides accepted an equitable exit. This pattern is worth tracking when assessing the relative bargaining positions of smart card patent holders versus semiconductor manufacturers.
Amatech v Infineon — key questions answered
The Federal Circuit dismissed Amatech Group Ltd.’s appeal on 6 February 2024 following Amatech’s voluntary motion under FRAP 42(b). No merits ruling was issued on the patentability of US9033250B2. Each side was ordered to bear its own costs. The dismissal resolved the appeal procedurally without any determination of patent validity or invalidity.
A voluntary dismissal under Federal Rule of Appellate Procedure 42(b) ends the appeal without a merits ruling. It does not confirm or invalidate the patent at issue. The enforceability of the patent depends on the underlying proceeding — such as a PTAB final written decision or district court judgment — not the appellate dismissal. The public record here does not specify whether dismissal was with or without prejudice.
The Federal Circuit’s dismissal does not resolve the validity of US9033250B2. Because the appeal was voluntarily dismissed under FRAP 42(b), no appellate judgment on patentability was entered. Validity is governed by the outcome of the underlying cancellation or invalidity proceeding. Companies seeking certainty on this patent’s enforceability should review the underlying PTAB or district court record directly.
The public record does not disclose Amatech’s reasons for voluntary dismissal. Common drivers of such decisions include commercial settlement, a licensing agreement, adverse assessment of appellate prospects, or a strategic decision to conserve litigation resources. The mutual cost-bearing order — rather than a cost award to Infineon — is consistent with a negotiated or pragmatic exit rather than a unilateral capitulation.
