Samsung v. G+ Communications: Federal Circuit Appeal Voluntarily Dismissed
Samsung Electronics and G+ Communications jointly agreed to dismiss a Federal Circuit appeal challenging the validity of US10594443B2, a patent covering HARQ information transmitting and receiving methods in wireless networks. The proceeding ended 142 days after filing, with each side bearing its own costs — leaving the merits unresolved.
A contested 5G HARQ patent appeal ends by mutual agreement
Samsung Electronics Co., Ltd. initiated appellate proceedings at the Court of Appeals for the Federal Circuit on 4 June 2024, challenging a patentability determination related to US10594443B2, held by G+ Communications, LLC. The patent — filed under application number US15/749354 — covers methods and nodes for transmitting and receiving Hybrid Automatic Repeat Request (HARQ) information, a core signalling mechanism in LTE and 5G wireless standards. The dispute was framed as an invalidity or cancellation action, suggesting the underlying proceeding most likely originated at the USPTO’s Patent Trial and Appeal Board.
The appeal was terminated on 24 October 2024 when the parties jointly agreed to dismissal under Federal Rule of Appellate Procedure 42(b), which permits voluntary dismissal by stipulation of all parties. The court ordered each side to bear its own costs, a neutral cost allocation that is consistent with a negotiated resolution rather than a clear-cut procedural concession by either party. Critically, no merits ruling was issued — the Federal Circuit made no determination on the validity or enforceability of US10594443B2.
The 142-day duration from filing to dismissal is notably brief for a Federal Circuit appeal, suggesting the parties reached agreement early in the briefing cycle — possibly before substantive briefs were fully exchanged. The public record does not disclose whether a licensing agreement, settlement payment, or cross-licence accompanied the dismissal. Because the appeal was withdrawn without prejudice to either party’s legal positions, US10594443B2 remains in its pre-appeal state with no Federal Circuit endorsement or invalidation on record.

Voluntarily dismissed: what the agreed termination means for both parties
Fed. R. App. P. 42(b): voluntary dismissal by stipulation
Rule 42(b) allows all parties to a Federal Circuit appeal to jointly file for dismissal without requiring court approval of any underlying terms. The court’s role is purely ministerial — it records the dismissal and allocates costs as agreed. Crucially, this mechanism produces no merits ruling: the Federal Circuit issues no opinion on patentability, claim construction, or validity. The legal status of US10594443B2 at the PTAB or district court level is unaffected by this appellate dismissal.
No merits adjudicationG+ Communications: validity challenge withdrawn, patent survives appeal
For G+ Communications, the voluntary dismissal means Samsung’s appellate challenge to US10594443B2 is extinguished at this level without a Federal Circuit invalidity ruling. The patent — covering HARQ signalling methods — retains whatever validity status it held before the appeal was filed. Whether the dismissal reflects a licensing arrangement or a strategic retreat by Samsung is not disclosed in the public record. The absence of a costs award against G+ suggests neither party conceded fault in the underlying proceeding.
Patent not invalidated at Federal CircuitSamsung: appeal withdrawn, future challenge options remain open
Samsung agreed to dismiss its own appeal, ending its attempt to overturn the patentability finding via the Federal Circuit in this proceeding. Because no merits ruling was issued, Samsung is not estopped from raising invalidity arguments in a different forum or a future proceeding, subject to any estoppel provisions that may apply from the underlying PTAB trial. The neutral cost order — each side bears its own — is consistent with a commercially negotiated exit rather than a litigation defeat.
No Federal Circuit estoppel createdHARQ patent survives: licensing exposure persists for wireless device makers
US10594443B2 covers HARQ information transmission methods that are foundational to LTE and 5G base station and device interoperability. With no Federal Circuit invalidity ruling on record, companies implementing HARQ-related signalling in compliant devices — smartphones, base stations, IoT modules — remain potentially exposed to licensing demands from G+ Communications. The dismissal may signal a settled commercial arrangement with Samsung, but the patent’s enforceability against other implementers is unchanged and unresolved by this proceeding.

Official order — verbatim text
The order records a mutual agreement to dismiss under Fed. R. App. P. 42(b) with each party absorbing its own costs. This language is procedurally neutral — it reflects no judicial assessment of the merits of the patentability dispute. The Federal Circuit neither affirmed nor reversed the underlying determination. For practitioners, the absence of any opinion means no precedent is created and no claim construction or validity analysis is on record from this court. The cost-neutrality provision is consistent with a commercially negotiated resolution rather than a concession by either side.
US10594443B2 — HARQ Information Transmitting and Receiving Methods
US10594443B2, filed under application number US15/749354, protects methods and node architectures for handling Hybrid Automatic Repeat Request (HARQ) information in wireless communications. HARQ is a link-layer protocol that combines forward error correction with retransmission requests, enabling the high reliability and low latency required in LTE and 5G NR networks. Patent claims directed at how HARQ feedback is encoded, transmitted, and interpreted by network nodes sit at the intersection of baseband processing and standards-essential patent territory.
Patents covering HARQ signalling methods carry significant strategic weight because HARQ compliance is non-optional for LTE and 5G-certified devices. Any smartphone SoC, base station modem, or IoT module meeting 3GPP standards must implement some form of HARQ. G+ Communications’ enforcement of US10594443B2 against Samsung — a global leader in both device and semiconductor markets — suggests the patent holder regards its claims as reading on commercially deployed implementations. Competitors and chipset vendors implementing HARQ in 5G products should treat this patent as a live licensing risk pending any future invalidity proceeding.
Should you run an FTO analysis against US10594443B2?
Any organisation designing, manufacturing, or commercialising LTE or 5G wireless devices — including smartphones, base stations, small cells, IoT modules, and 5G chipsets — should assess exposure to US10594443B2. Because no Federal Circuit invalidity ruling was issued in this appeal, the patent’s claims remain intact. Product teams implementing HARQ feedback mechanisms in 3GPP-compliant hardware or firmware cannot rely on this litigation to confirm design freedom.
PatSnap Eureka’s FTO Search Agent can map the claim scope of US10594443B2 against your product’s HARQ implementation, identify related family members in the G+ Communications portfolio, and surface prior art that was not considered in the underlying PTAB proceeding. With standards-essential patent exposure in 5G remaining a top IP risk, a targeted FTO and landscape analysis is the most efficient way to quantify and manage your licensing risk before commercialisation.

What this case signals for the 5G wireless patent licensing landscape
A quietly dismissed Federal Circuit appeal over a core HARQ patent leaves enforcement risk unresolved for wireless device and infrastructure makers.
Voluntary dismissal without merits ruling preserves enforcement options
Because the Federal Circuit issued no opinion on US10594443B2, G+ Communications retains full enforcement posture against third parties. Companies that assumed Samsung’s appeal would produce a public invalidity ruling should reassess — the patent exits this proceeding legally intact. Monitoring G+ Communications’ licensing and litigation activity against other 5G implementers is now the critical intelligence task.
Neutral cost order suggests negotiated exit, not Samsung capitulation
An each-side-bears-own-costs outcome under Rule 42(b) typically signals a bilateral commercial agreement rather than a unilateral concession. Whether that agreement involves a licence, cross-licence, or covenant not to sue is undisclosed. Competitors and licensees of either party should consider what a Samsung-G+ arrangement might mean for their own exposure to this HARQ patent portfolio.
Samsung v G+ — key questions answered
The Federal Circuit appeal in Case 24-1902 was voluntarily dismissed by agreement of both parties on 24 October 2024 under Fed. R. App. P. 42(b). No merits ruling was issued. The dispute concerned the patentability of US10594443B2, a patent covering HARQ information transmitting and receiving methods. Each party bears its own appellate costs.
The patent at issue is US10594443B2 (application number US15/749354), assigned to G+ Communications, LLC. It covers methods and nodes for transmitting and receiving Hybrid Automatic Repeat Request (HARQ) information in wireless networks — a protocol integral to LTE and 5G NR standards compliance.
No. A voluntary dismissal under Fed. R. App. P. 42(b) produces no judicial ruling on validity or patentability. The Federal Circuit neither confirmed nor invalidated the claims of US10594443B2. The patent’s legal status remains whatever it was at the conclusion of the underlying PTAB proceeding, unmodified by this appellate dismissal.
Rule 42(b) allows all parties to a Federal Circuit appeal to jointly stipulate to dismissal without the court reviewing the merits. The court simply records the dismissal and implements the agreed cost allocation. In patent cases, this is commonly used when parties have reached a commercial resolution — such as a licence or settlement — but it creates no precedent and no claim construction record.
Hybrid Automatic Repeat Request (HARQ) is a mandatory link-layer reliability mechanism in LTE and 5G NR standards, combining forward error correction with selective retransmission. Because HARQ compliance is non-optional for 3GPP-certified devices, patents with claims that read on HARQ implementation carry potential standards-essential patent status. Licensing exposure can extend to any manufacturer of smartphones, modems, base stations, or IoT modules supporting LTE or 5G.
