C47 Technologies v. Lenovo & Samsung: Dual-Capture Camera Patent Dismissed With Prejudice
C47 Technologies LLC asserted US10984605B2 — a dual-capture and portrait-mode camera patent — against Lenovo and Samsung’s Galaxy smartphone lines in E.D. Texas. After 474 days of litigation before Judge Rodney Gilstrap, C47 voluntarily dismissed all claims with prejudice, permanently closing its enforcement route against these defendants.
Camera patent litigation ends permanently as C47 walks away with prejudice
C47 Technologies LLC, a patent assertion entity holding US10984605B2 covering dual-capture and portrait-mode camera functionality, filed suit on May 17, 2024 in the Eastern District of Texas against Lenovo (Shanghai) Electronics Technology Co. and Samsung Electronics America. The accused products spanned Samsung’s Galaxy A, M, Note, S10, S20, and S21 series — devices featuring Dual Capture, Live Focus, Portrait Mode, and Portrait Video capabilities. The case was assigned to Judge Rodney Gilstrap, one of the most patent-experienced federal judges in the country.
On September 3, 2025, C47 filed a Notice of Voluntary Dismissal with Prejudice. Judge Gilstrap accepted and acknowledged the notice, dismissing all of C47’s claims against all defendants with prejudice. The court further ordered that each party bear its own costs and attorneys’ fees, and denied all remaining pending requests for relief as moot. The clerk was directed to close both the member case and the consolidated lead case, leaving no live disputes in the series.
A dismissal with prejudice after 474 days — well past initial pleadings and likely into claim construction territory — suggests the case may have resolved through negotiation, licensing, or a recognition that the merits position had weakened. The public record does not disclose whether any consideration changed hands. The each-party-bears-own-costs order is consistent with a negotiated exit rather than a contested motion outcome, though the specific commercial terms, if any, remain confidential.

Dismissed with prejudice: what the voluntary exit means for both parties
Voluntary dismissal with prejudice permanently bars re-filing
A voluntary dismissal with prejudice operates as a final adjudication on the merits under federal procedural rules. Unlike a dismissal without prejudice — which preserves the plaintiff’s right to re-file — C47’s election here permanently extinguishes its ability to reassert US10984605B2 against Lenovo and Samsung on these same claims. The court’s acceptance of the notice formalised that bar.
No re-filing permittedC47 loses its enforcement right against these defendants permanently
By dismissing with prejudice, C47 forfeits any future infringement claim against Lenovo and Samsung under US10984605B2 for the accused Galaxy product lines. Whether this reflects a licensing resolution, a weakened claim construction position, or a strategic portfolio decision is not disclosed in the public record. C47 may retain enforcement rights against other defendants not party to this action.
Enforcement permanently closedSamsung and Lenovo secured permanent immunity from this patent claim
The with-prejudice dismissal gives Lenovo and Samsung a complete and permanent defence against any future assertion of US10984605B2 by C47 on the same accused products and claims. The each-party-bears-costs order means they received no fee award, which is consistent with a negotiated resolution rather than a contested win on the merits. Their Galaxy product lines can continue without this specific litigation cloud.
Full res judicata protectionPortrait and dual-capture camera IP remains a live risk for the broader market
While Samsung and Lenovo are shielded, US10984605B2 remains a granted patent that C47 could assert against other smartphone OEMs offering similar dual-capture or portrait-mode features. Companies with comparable camera systems — particularly those not party to this litigation — should assess their exposure. The resolution of this case without a merits ruling leaves the patent’s validity and scope untested by any court.

Official order — verbatim text
The court’s order accepts C47’s notice and explicitly acknowledges the with-prejudice character of the dismissal — leaving no ambiguity about finality. The denial of all pending relief as moot confirms that no substantive motions were resolved on the merits. The parties-bear-own-costs direction, rather than a fee-shifting award, is consistent with a mutually agreed exit and suggests neither side sought to characterise the other’s conduct as exceptional under 35 U.S.C. § 285. The closure of both the member case and the consolidated lead case signals there are no remaining related disputes in this series.
US10984605B2 — Dual-Capture and Portrait-Mode Camera Systems
US10984605B2 (application number US17/069690) covers technology relating to dual-capture camera systems and portrait-mode imaging — features that allow smartphones to simultaneously capture data from multiple lenses to produce depth-aware images, background blur, and live focus effects. This class of technology sits at the intersection of computational photography and multi-sensor hardware integration, and has become a standard feature tier in mid-to-premium Android smartphones over the past several years.
The patent’s commercial significance is underscored by the breadth of the accused product list: six distinct Samsung Galaxy series spanning entry-level (A Series, M Series) through flagship (S20, S21, Note Series) segments. This cross-tier accusation strategy suggests the asserted claims may be drafted broadly enough to cover both hardware-level dual-camera capture and software-driven portrait simulation. For OEMs and camera module suppliers, the unresolved validity of this patent represents a continuing risk factor — particularly as portrait and computational photography features migrate further down the price stack.
Should you run an FTO analysis against US10984605B2?
Any OEM, ODM, or camera software platform developer offering dual-capture, portrait mode, live focus, or portrait video features on Android or other mobile platforms should treat US10984605B2 as an active risk. The patent was not invalidated, its claim scope was never construed by a court, and C47 retains full enforcement rights against parties not named in this case. The breadth of the accused Samsung product lines — from budget A Series to flagship S21 — suggests the claims may read on widely deployed feature implementations.
PatSnap Eureka’s FTO Search Agent can map the claim language of US10984605B2 against your specific camera pipeline implementation, identify prior art candidates that could support an IPR petition, and flag continuation applications in the same family that may broaden or narrow the risk profile. For product teams shipping computational photography features in the next development cycle, an FTO review against this patent and its family is a commercially prudent step before launch.

What this case signals for the smartphone camera IP landscape
A with-prejudice exit after 474 days in Gilstrap’s court carries strategic weight beyond the two named defendants.
Untested patent validity is a risk multiplier for other OEMs
Because the case resolved without any claim construction ruling or validity determination, US10984605B2 carries no judicial track record. OEMs selling devices with dual-capture, portrait mode, or live focus features have no prior art findings or claim scope guidance to rely on. A fresh assertion against a different defendant would start from zero.
E.D. Texas and Judge Gilstrap remain a high-stakes venue for camera patent assertions
C47’s choice of E.D. Texas and the consolidated case structure signals a deliberate enforcement strategy. Gilstrap’s docket moves efficiently and his court has experience with complex multi-defendant patent cases. Companies in the smartphone camera supply chain should monitor new filings in this district closely.
C47 v Lenovo — key questions answered
C47 Technologies sued Samsung Electronics America and Lenovo in the Eastern District of Texas asserting US10984605B2 against Galaxy smartphone camera features including Dual Capture, Live Focus, and Portrait Mode. After 474 days, C47 voluntarily dismissed all claims with prejudice on September 3, 2025. The court ordered each party to bear its own costs and fees.
A dismissal with prejudice permanently bars C47 Technologies from reasserting US10984605B2 against Samsung Electronics America and Lenovo on the same accused products and claims. It functions as a final judgment on the merits. However, C47 retains the right to assert the patent against other defendants not party to this action.
The complaint accused Samsung’s Galaxy A Series, Galaxy M Series, Galaxy Note Series, Galaxy S10 Series, Galaxy S20 Series, and Galaxy S21 Series product lines. Specific accused features included Dual Capture, Live Focus, Portrait Mode, and Portrait Video — spanning entry-level through flagship device tiers.
No. The case was dismissed with prejudice on C47’s voluntary notice before any claim construction ruling or validity determination was issued. US10984605B2 remains a granted patent with no judicial record on its validity or claim scope. This means the patent presents an unresolved risk for OEMs not party to this litigation.
C47 Technologies was represented by Christopher A. Honea of Garteiser Honea PLLC. The defendants were represented by Melissa Richards Smith of Gillam & Smith LLP. The case was presided over by Judge Rodney Gilstrap in the Eastern District of Texas.
