Advanced Coding Technologies v. Samsung: Joint Dismissal After 623-Day Video Codec Battle
Advanced Coding Technologies LLC asserted six video encoding and decoding patents against Samsung Electronics in the Eastern District of Texas. After 623 days of litigation before Judge Rodney Gilstrap, the parties jointly moved to dismiss all claims with prejudice — each side bearing its own costs — suggesting a private resolution outside the public record.
Six video codec patents, two Samsung entities, one joint exit
On December 30, 2022, Advanced Coding Technologies LLC (ACT) filed suit against Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc. in the Eastern District of Texas, asserting six U.S. patents covering multi-view video encoding, moving image data processing, moving picture encoding and decoding systems, video coding data transmission, and video-emphasis encoding and decoding. The case was assigned to Judge Rodney Gilstrap, the court’s most experienced patent jurist.
On September 13, 2024 — 623 days after filing — the court granted a joint motion to dismiss all claims with prejudice. Every claim ACT brought against Samsung, and every counterclaim or defense Samsung asserted against ACT, was dismissed simultaneously. The order explicitly required each party to bear its own legal costs, which is a common feature of negotiated resolutions and distinguishes this outcome from a litigation victory on the merits.
The joint nature of the dismissal and the symmetrical cost-bearing arrangement strongly suggest the parties reached a private settlement, though no terms have been disclosed on the public docket. The 623-day duration is consistent with cases that proceed through claim construction before resolving. What drove ACT to assert six patents simultaneously — and what ultimately motivated both sides to exit — remains outside the public record.

Dismissed with prejudice: what the joint order means for both parties
With prejudice means permanent — no second bite at the apple
A dismissal with prejudice under Rule 41 is a final adjudication on the merits for res judicata purposes. ACT cannot refile these six patent claims against Samsung in any federal court. The joint nature signals mutual agreement, but the ‘with prejudice’ designation was likely a concession ACT made in exchange for terms not disclosed publicly. Samsung’s counterclaims and defenses were also dismissed, releasing any invalidity or unenforceability findings it sought.
Rule 41 — permanent bar on refilingACT forfeits all claims against Samsung — patents survive for others
ACT’s dismissal with prejudice extinguishes its rights against Samsung specifically, but the six asserted patents remain in force and could be asserted against other defendants. If ACT received a licensing payment as part of a private settlement — common in jointly-dismissed NPE cases — the patents may still generate revenue elsewhere. However, Samsung obtained no invalidity ruling, meaning the patents emerge without a formal validity cloud from this proceeding.
Patents survive; Samsung-specific bar onlySamsung exits cleanly — no admitted liability, no validity ruling
Samsung secured a full exit from the litigation without any finding of infringement and without a public record of the terms. Critically, Samsung’s own counterclaims — which likely included invalidity and non-infringement defenses — were also dismissed, meaning Samsung did not secure a formal invalidity ruling it could use as a shield against future ACT assertions or in related proceedings. The own-costs arrangement avoids any fee-shifting exposure for either side.
Clean exit — no liability findingVideo codec IP remains live — watch for ACT enforcement against other OEMs
With six video encoding and decoding patents still valid and unencumbered by this case, ACT’s portfolio poses ongoing risk for other consumer electronics manufacturers, streaming hardware vendors, and video processing platform companies. The patents span multi-view video, re-encoding systems, and transmission architectures — technology embedded across modern display, mobile, and broadcast products. Other OEMs operating in these spaces should monitor ACT’s filing activity closely.

Official order — verbatim text
The court’s order tracks the joint motion language precisely, dismissing all claims and counterclaims with prejudice in a single operative paragraph. The phrasing ‘noting its joint nature’ signals the court exercised minimal independent scrutiny — consistent with Rule 41(a)(2) practice where joint motions are routinely granted. The simultaneous dismissal of Samsung’s defenses and ACT’s claims, paired with the own-costs instruction, leaves no winning party on the record and no legal findings that bind either side in future proceedings involving these patents against different defendants.
US8090025B2 — multi-view video encoding and decoding methods
The six asserted patents collectively cover a broad sweep of video compression and codec technology: multi-view video encoding and decoding (US8090025B2), moving image data processing (US9986303B2), full encode/decode/re-encode pipeline systems (US8139150B2), moving-picture coding apparatus and methods (US9445041B2), video coding data transmission systems (US6845128B2), and video-emphasis encoding (US10218995B2). The portfolio spans application filings across multiple generations of video codec standardisation, suggesting it was assembled to capture value across H.264, HEVC, and related codec implementations embedded in consumer electronics.
For Samsung — a major manufacturer of smart televisions, mobile devices, and display products — exposure across six video codec patents simultaneously represents substantial claim surface area. The patents’ coverage of encoding apparatus, transmission systems, and re-encoding pipelines maps directly onto Samsung’s core consumer hardware and software stack. For competitors and suppliers operating in the same space, the continued validity of this portfolio post-dismissal means the litigation risk has not been neutralised — it has simply been redirected away from Samsung.
Should you run an FTO against US8090025B2 and the ACT video codec portfolio?
Any company developing, manufacturing, or licensing products that perform video encoding, decoding, multi-view processing, or video data transmission — including smart TV SoC vendors, mobile device OEMs, video streaming hardware companies, broadcast equipment makers, and video platform software developers — should assess their exposure to ACT’s six-patent portfolio. The dismissal with prejudice resolves ACT’s claims only against Samsung; every other potential defendant remains fully exposed.
PatSnap Eureka’s FTO Search Agent can map each of ACT’s six patents against your product architecture, identify claim elements most likely to be in-suit, and surface prior art that may support invalidity arguments. Given that no court has ruled on the validity of any of these patents, a proactive FTO and prior art search is the most reliable way to quantify your risk before ACT’s next enforcement campaign targets your sector.

What this case signals for the video codec IP enforcement landscape
Six simultaneous video encoding patents, E.D. Texas, Samsung as defendant — this case follows a recognisable NPE enforcement playbook.
Joint dismissal without costs is the hallmark of a confidential settlement
When both parties move jointly to dismiss with prejudice and each bears its own costs, the public record almost never tells the full story. This pattern — common in E.D. Texas NPE cases — typically signals a licensing payment to the patent holder in exchange for a clean exit. The absence of any cost award to either side confirms neither party ‘won’ on the merits in the traditional sense.
No invalidity ruling means all six patents remain enforceable against third parties
Samsung’s decision to dismiss its own counterclaims — rather than press for an invalidity finding — may reflect confidence in its exit terms, but it leaves ACT’s portfolio intact for future enforcement. Companies in the video processing, smart TV, mobile camera, and broadcast encoding sectors should treat these six patents as live litigation risk and consider freedom-to-operate analysis before deploying related technology.
Advanced v Samsung — key questions answered
ACT filed suit against Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc. in the Eastern District of Texas on December 30, 2022, asserting six video encoding and decoding patents. On September 13, 2024, Judge Gilstrap granted a joint motion to dismiss all claims with prejudice, with each party bearing its own costs. No merits ruling was issued.
ACT asserted US8090025B2, US9986303B2, US8139150B2, US9445041B2, US6845128B2, and US10218995B2. The patents cover multi-view video encoding and decoding, moving image data processing, encode/decode/re-encode pipelines, moving-picture coding apparatus, video coding data transmission, and video-emphasis encoding and decoding technology.
No. A dismissal with prejudice bars ACT from reasserting these patents against Samsung specifically, but it does not constitute a ruling on validity or infringement. Because Samsung’s invalidity counterclaims were also dismissed, no court has ruled on the validity of any of ACT’s six patents. They remain in force and enforceable against other defendants.
The case was not decided on the merits. The joint motion and symmetrical own-costs arrangement strongly suggest the parties reached a private settlement, though no financial terms or licensing details have been disclosed on the public docket. This pattern is consistent with confidential licensing resolutions common in E.D. Texas NPE litigation.
The dismissal resolves ACT’s claims only against Samsung. All six patents remain valid and unencumbered by any invalidity finding. Other OEMs, SoC developers, streaming hardware vendors, and video platform companies that implement video encoding, decoding, or transmission functionality remain potentially exposed to assertion by ACT. A freedom-to-operate analysis against ACT’s portfolio is advisable for companies in these sectors.
