DivX v. LG Electronics & Realtek: Six-Patent Smart TV Dispute Dismissed Without Prejudice
DivX, LLC brought a six-patent infringement action against LG Electronics and chip supplier Realtek Semiconductor in Delaware, targeting LG smart TVs and video processing components. After a 2021 stay left the case in its infancy — no scheduling order, no discovery — the court granted dismissal without prejudice, closing a 1,364-day proceeding without reaching the merits.
A stayed Delaware video-patent case closed before discovery ever opened
DivX, LLC filed suit on September 9, 2020, in the District of Delaware against LG Electronics, Inc., LG Electronics U.S.A., Inc., and Realtek Semiconductor Corp., asserting infringement of six U.S. patents covering video processing and streaming technology. The accused products include the LG 43UM6910PUA smart television, the LG E9 Glass 65-inch Class 4K Smart OLED TV, the LG Alpha 9 Gen 2 processor, and related LG video processing devices — placing both the end-product manufacturer and its chip supplier in the crosshairs simultaneously.
The court stayed the case in 2021, and when DivX moved to dismiss without prejudice, Judge Jennifer L. Hall granted the motion, noting the case remained at its earliest stages — no scheduling order had been entered and no discovery had taken place. The dismissal without prejudice means the complaint is terminated but DivX’s underlying patent claims are not extinguished; DivX retains the ability to refile the same allegations subject to applicable statutes of limitations and any intervening legal developments.
The 1,364-day duration is notable given how little procedural progress was made — the case was effectively suspended for most of its life. The public record does not disclose what drove DivX’s decision to seek dismissal at this stage, whether a parallel licensing negotiation, an IPR or PTAB proceeding affecting the asserted patents, or a strategic portfolio realignment. The absence of any merits ruling leaves the validity and infringement questions entirely open, making this a case worth monitoring for potential refiling activity.

Dismissed without prejudice: what the court’s order means for each party
Dismissal without prejudice leaves the door open
A dismissal without prejudice terminates the current action but does not adjudicate the underlying claims on their merits. The court exercised its discretion under the applicable procedural standard, citing the case’s infancy — no scheduling order, no discovery — as a key factor. DivX is not barred from refiling the same patent claims in a new action, provided it acts within applicable statutes of limitations.
No merits determinationDivX retains its patents and its right to refile
Because the dismissal is without prejudice, DivX’s six asserted patents — covering video processing and streaming methods — remain enforceable and unchallenged by any court ruling. DivX preserves optionality: it can refile against LG or Realtek, pursue licensing discussions with the case closed, or redirect enforcement resources elsewhere. The outcome does not constitute any admission of non-infringement or invalidity.
Patents remain enforceableLG and Realtek get relief — but no permanent protection
LG Electronics and Realtek Semiconductor avoid any infringement finding, damages exposure, or injunctive risk from this action. However, because the dismissal is without prejudice, neither defendant has obtained a ruling that shields them from future suit on the same patents. LG’s smart TV product lines and Realtek’s video processing chips remain potentially exposed if DivX elects to refile.
No permanent bar to refilingSmart TV supply chain faces unresolved video-patent exposure
The dismissal without prejudice provides no market clarity for the smart TV ecosystem. Competitors, component suppliers, and licensees operating in video processing and streaming delivery should note that DivX’s patent portfolio remains active and litigation-ready. Companies designing around or licensing these technologies should monitor DivX’s filing activity, as a refiling targeting similar products or updated accused platforms remains plausible.

Official order — verbatim text
The court’s order granting dismissal without prejudice is explicitly grounded in the case’s procedural immaturity: no scheduling order had been entered and no discovery had occurred when the stay was lifted. The court’s discretionary grant of DivX’s own motion signals no adversarial merits finding — neither infringement nor invalidity was considered. For LG and Realtek, the relief is temporary absent a covenant not to sue or settlement. For DivX, the order preserves full enforcement optionality across all six asserted patents.
US10484749B2 and five further DivX video processing patents
The six asserted patents — US10484749B2, US8832297B2, US10212486B2, US8977768B2, US10000000B2, and US10412141B2 — span DivX’s core video processing and streaming delivery portfolio. Filed across application dates ranging from approximately 2010 to 2018, these patents cover technologies including adaptive video streaming, device interoperability, secure playback, and processing pipeline architecture relevant to modern smart television platforms and the chips that power them.
DivX’s portfolio occupies a strategically significant position in the smart TV ecosystem, where video codec standards, adaptive bitrate streaming, and chip-level media processing converge. LG’s Alpha 9 Gen 2 processor and Realtek’s video processing components sit at the hardware layer targeted by these claims. For consumer electronics OEMs, SoC designers, and streaming platform operators, the breadth of this six-patent assertion underscores the licensing and design-around risk inherent in deploying proprietary video processing architectures.
Should your team run an FTO against DivX’s video processing patents?
Any company designing, manufacturing, or integrating smart TV platforms, video processing SoCs, or adaptive streaming stacks should treat DivX’s portfolio as an active enforcement risk. The dismissal without prejudice in this case does not extinguish infringement exposure. Product teams working on OLED or LCD smart TV hardware, video decoder chips, or cloud-to-device streaming delivery pipelines should conduct freedom-to-operate analysis against US10484749B2 and the five related patents before product launch or platform update.
PatSnap Eureka’s FTO Search Agent enables IP and R&D teams to map claim scope across all six DivX patents, identify prior art that may narrow enforceability, and benchmark design-around options against the current claim landscape. Eureka’s prosecution history analysis surfaces any claim amendments that may affect scope, while portfolio monitoring alerts flag new DivX continuations or divisionals that could extend coverage into next-generation smart TV and streaming architectures.

Portfolio viewWhat this case signals for the smart TV and video processing IP landscape
A stayed, pre-discovery dismissal without prejudice is rarely the end of the story for a six-patent video technology portfolio.
Pre-discovery dismissals without prejudice warrant close monitoring
When a patent holder dismisses a multi-patent action before any discovery, it often signals a strategic pause rather than an exit. DivX retains full enforcement rights. Companies in the smart TV supply chain — including chip designers and OEM integrators — should track DivX’s patent prosecution and litigation activity for signs of a renewed enforcement campaign.
Multi-defendant structure signals coordinated supply-chain targeting
By naming both LG Electronics and chip supplier Realtek Semiconductor, DivX adopted a strategy of attacking end-product and component layers simultaneously. This approach is increasingly common in consumer electronics patent enforcement and signals that DivX views video processing IP as covering the full manufacturing chain, not just finished goods.
Six-patent portfolio breadth increases refile and licensing leverage
With six patents spanning video processing, streaming delivery, and device integration, DivX holds a portfolio capable of supporting multiple independent claim theories. Any refile could assert a subset of patents, target updated LG or Realtek product lines, or be combined with parallel PTAB or ITC proceedings to maximise pressure across enforcement venues.
Stay history and PTAB activity may be decisive in any refiled action
The original stay likely reflected parallel PTAB or IPR proceedings against one or more of the six asserted patents. Before any refile, defendants and potential licensees should audit the inter partes review history of US10484749B2, US8832297B2, US10212486B2, US8977768B2, US10000000B2, and US10412141B2 to assess surviving claim scope and validity risk.
Divx v LG — key questions answered
The District of Delaware dismissed the case without prejudice on June 4, 2024. DivX had filed a six-patent infringement action against LG Electronics, LG Electronics U.S.A., and Realtek Semiconductor in September 2020. The court stayed proceedings in 2021. When DivX moved to dismiss without prejudice, Judge Hall granted the motion, noting no scheduling order had been entered and no discovery had occurred.
DivX asserted six patents: US10484749B2, US8832297B2, US10212486B2, US8977768B2, US10000000B2, and US10412141B2. These patents cover video processing, streaming delivery, device interoperability, and related smart TV technologies. The accused products included LG smart televisions and the LG Alpha 9 Gen 2 processor, as well as Realtek video processing components.
A dismissal without prejudice does not bar DivX from refiling the same claims in a new action. DivX’s six patents remain enforceable and no court has ruled on validity or infringement. DivX could refile against LG, LG U.S.A., or Realtek in the future, subject to applicable statutes of limitations and any changes in patent scope resulting from PTAB or other proceedings.
The public record cited in the court’s order confirms the case was stayed in 2021 but does not specify the precise reason in the available verdict text. Patent cases in Delaware are frequently stayed pending inter partes review or other PTAB proceedings affecting asserted patents. The stay left the case with no scheduling order and no discovery when DivX ultimately sought dismissal.
DivX accused the LG 43UM6910PUA smart television, the LG E9 Glass 65-inch Class 4K Smart OLED TV (Model OLED65E9PUA), the LG Alpha 9 Gen 2 processor, and LG video processing devices and components thereof. By also naming Realtek Semiconductor, DivX targeted both the end-product manufacturer and the chip-level supplier in a coordinated enforcement strategy.
