Electronic Edison v. Samsung: Wireless Charging Case Dismissed With Prejudice
Electronic Edison Transmission Technologies, LLC asserted three wireless power transfer patents against Samsung’s Galaxy smartphones, foldables, and smartwatches in the Eastern District of Texas. The parties jointly filed a stipulated dismissal with prejudice under FRCP 41(a)(1)(A)(ii) after just 263 days — each side bearing its own costs, strongly suggesting a private settlement was reached.
Wireless Power IP Clash Ends Quietly as Samsung and Edison Part Ways
Filed on 16 February 2024 in the Eastern District of Texas before Judge Rodney Gilstrap, this case pitted Electronic Edison Transmission Technologies, LLC — a patent assertion entity holding wireless charging IP — against Samsung Electronics Co., Ltd. and its U.S. subsidiary Samsung Electronics America, Inc. The complaint targeted high-profile consumer devices including the Galaxy S20 series, Galaxy Z Fold foldables, and Galaxy smartwatches, all alleged to infringe through implementation of Qi-standard wireless power transfer and reverse charging (‘Wireless PowerShare’) functionality.
On 5 November 2024, the parties filed a joint FRCP 41(a)(1)(A)(ii) stipulated notice of dismissal with prejudice. Judge Gilstrap accepted and acknowledged the dismissal, closing all claims against all defendants. No fee award was entered — each side is to bear its own costs, expenses, and attorneys’ fees. A dismissal with prejudice permanently bars Electronic Edison from re-asserting these three patents against Samsung on the same claims, representing a final resolution on the merits as a matter of procedural law.
Resolution in under nine months is notably swift for a multi-patent assertion against a major OEM in E.D. Texas, where cases regularly run 18–24 months before trial. The speed of resolution, combined with the mutual cost-bearing arrangement and the absence of any public judgment, is consistent with a confidential settlement having been reached — though the public record does not confirm financial terms. What remains unknown is whether any licensing arrangement, design-around commitment, or ongoing commercial agreement underpins the dismissal.

Dismissed with prejudice: what the stipulated exit means for both parties
FRCP 41(a)(1)(A)(ii): the joint stipulated dismissal explained
Rule 41(a)(1)(A)(ii) allows parties to dismiss an action without a court order when all appearing parties sign the stipulation. Here, both plaintiff and defendants agreed to dismiss with prejudice — meaning the court did not adjudicate the merits. The dismissal carries the same res judicata effect as a final judgment, permanently barring re-filing of these specific claims by Electronic Edison against Samsung.
No merits adjudicationDismissed with prejudice: Electronic Edison’s claims are extinguished
Unlike a without-prejudice dismissal — which preserves the right to re-file — a with-prejudice dismissal permanently extinguishes the plaintiff’s right to assert these three patents against Samsung on these claims. Electronic Edison has forfeited any future infringement action against Samsung based on US9871415B2, US9448603B2, and US10454305B2. The with-prejudice designation is clearly stated on the public docket, leaving no ambiguity.
Claims permanently barredSamsung exits without any adverse judgment on its Qi products
Samsung obtains a complete exit from this litigation with no court finding of infringement, validity, or damages. The with-prejudice dismissal insulates Samsung from any future suit by Electronic Edison on these patents for the same accused products. The mutual cost-bearing order signals neither side secured a clear litigation advantage, which is consistent with a negotiated resolution rather than a unilateral capitulation by either party.
No infringement findingQi wireless power IP: settlement pressure on other OEMs remains
The swift, quiet resolution of a three-patent wireless charging assertion against one of the world’s largest smartphone OEMs suggests these patents retain enough perceived strength to drive commercial resolution. Other manufacturers deploying Qi wireless charging or reverse charging features — particularly those not yet covered by a licence — should treat this outcome as a signal that Electronic Edison’s portfolio may still be in active enforcement mode against remaining targets.

Official order — verbatim text
The court’s order is purely administrative — it accepts and acknowledges the parties’ joint stipulation under FRCP 41(a)(1)(A)(ii) without reaching any substantive merits. The explicit ‘with prejudice’ designation is determinative: it forecloses any future infringement action by Electronic Edison against Samsung under these three patents on these claims. The ‘each party bears its own costs’ provision, ordered simultaneously, removes any fee-shifting signal, leaving the underlying commercial terms of resolution entirely within the parties’ private agreement.
US9871415B2, US9448603B2 & US10454305B2 — Qi wireless power transfer technology
The three asserted patents — US9871415B2 (application US15/242245), US9448603B2 (application US13/472447), and US10454305B2 (application US15/841791) — cover wireless power transfer technology aligned with the Qi standard developed by the Wireless Power Consortium. The patents span power transmission management, control configurations, and bidirectional/reverse charging functionality. The breadth of accused products — flagship smartphones, foldable devices, and smartwatches — suggests the claims are written at a level of generality capable of reading on standard-compliant implementations rather than purely proprietary Samsung architectures.
From a portfolio enforcement perspective, standard-essential or standard-adjacent wireless charging patents present a structurally attractive assertion target: every OEM shipping a Qi-certified device potentially falls within the claim scope, creating broad licensing leverage. Electronic Edison’s selection of E.D. Texas and the targeting of Samsung’s most commercially prominent product lines — Galaxy S20, Galaxy Z Fold, and Galaxy wearables — is consistent with an enforcement strategy designed to establish licensing precedent across the consumer electronics industry. Competitors and supply chain participants in the Qi ecosystem should monitor this portfolio closely.
Should your Qi-compliant product line be cleared against US9871415B2 and related patents?
Any company shipping smartphones, tablets, wearables, earbuds, or charging accessories that implement Qi wireless charging or reverse wireless charging should assess its exposure to this three-patent family. The accused Samsung products span multiple form factors and price tiers, indicating the asserted claims are not limited to premium devices. R&D and product teams planning new Qi implementations — or refreshing existing wireless power architectures — should commission FTO analysis before launch, not after receiving a demand letter.
PatSnap Eureka’s FTO Search Agent can map your product’s wireless power transfer architecture against the claim scope of US9871415B2, US9448603B2, and US10454305B2 in minutes — identifying overlap, file-history prosecution disclaimers, and relevant prior art that may limit enforceability. Eureka also tracks the full Electronic Edison portfolio for new continuations or divisionals that could extend assertion risk beyond these three granted patents.

What this case signals for the wireless charging IP landscape
A fast, confidential exit in E.D. Texas suggests Qi wireless power patents carry real commercial leverage — even against a defendant the size of Samsung.
Speed of resolution signals credible patent strength or licensing leverage
Cases asserting three patents against Samsung that settle in under nine months in E.D. Texas are uncommon. The rapid timeline — before claim construction or any substantive rulings — suggests either the patents were perceived as strong enough to drive early licensing talks, or Samsung prioritised business certainty over litigation attrition. Either reading is commercially meaningful for other wireless charging defendants.
Mutual cost-bearing signals negotiated parity, not capitulation
The absence of any fee award in either direction is consistent with a balanced negotiated exit. Had Samsung clearly prevailed on invalidity or non-infringement arguments, it would typically seek fees under 35 U.S.C. § 285. The equal cost split suggests both sides found acceptable commercial terms without either party conceding material weakness.
Electronic v Samsung — key questions answered
Dismissed with prejudice means Electronic Edison permanently loses the right to sue Samsung again on US9871415B2, US9448603B2, and US10454305B2 for the same accused products and claims. The dismissal carries res judicata effect equivalent to a final judgment, even though no court ruling on infringement or validity was issued. The stipulation was filed jointly under FRCP 41(a)(1)(A)(ii).
The accused products included the Galaxy S20 series smartphones, Galaxy Z Fold foldable phones incorporating ‘Wireless PowerShare’ or ‘Reverse Charging’ functionality compliant with the Qi standard, and Galaxy smartwatches. The common thread is implementation of Qi-standard wireless power transfer technology, suggesting the patents are directed at standard-compliant implementations.
The public docket does not disclose any damages award, judgment, or licensing fee. The case was resolved by joint stipulated dismissal with each party bearing its own costs. This structure is consistent with a confidential private settlement, but no financial terms are confirmed in the public record. No fee award was made in either direction.
The with-prejudice Samsung dismissal protects only Samsung. Other OEMs shipping Qi-compliant devices — including those with reverse wireless charging features — remain potentially exposed to assertion by Electronic Edison. The swift resolution against Samsung may indicate the patents have perceived commercial strength, and the portfolio should be monitored for new enforcement actions against other targets.
The Eastern District of Texas, and Judge Rodney Gilstrap’s court in particular, is a historically popular venue for patent assertion entities due to its plaintiff-friendly scheduling, experienced patent docket, and rigorous but predictable case management. E.D. Texas consistently ranks among the top U.S. districts by patent case filings. Filing before Judge Gilstrap — who handles a large share of the district’s patent docket — is a deliberate strategic choice by plaintiffs seeking efficient case progression.
