Multimedia Technologies v. LG Electronics: Jury Clears LG on All Smart TV UI Patents
Singapore-based Multimedia Technologies asserted five smart TV user interface patents against LG Electronics in the Eastern District of Texas. After a five-day jury trial in May 2025, the jury returned a unanimous verdict finding no infringement and invalidating every asserted claim — awarding LG cost recovery after 901 days of litigation.
Singapore patent holder’s smart TV IP portfolio wiped out at trial
Multimedia Technologies Pte. Ltd., a Singapore-incorporated patent assertion entity, filed suit against LG Electronics, Inc. and LG Electronics USA, Inc. in the Eastern District of Texas on December 23, 2022. The complaint asserted up to eleven patents covering smart television user interface technologies, including application panel management, global panel navigation, video-on-demand delivery, and live TV channel-change systems — all core to LG’s smart TV platform.
The case proceeded to a jury trial commencing May 19, 2025. On May 23, 2025, the jury returned a unanimous verdict finding that LG did not infringe any of the five asserted claims — claim 8 of the ‘254 patent, claims 10 and 11 of the ‘174 patent, claim 21 of the ‘040 patent, claim 10 of the ‘805 patent, and claim 19 of the ‘255 patent — and further found each of those asserted claims invalid. The court entered judgment for LG on June 11, 2025, granting cost recovery.
The 901-day duration from filing to final judgment is consistent with E.D. Tex. cases that proceed through full fact and expert discovery to jury trial rather than settling. The dual finding of non-infringement and invalidity is a complete defence victory and forecloses any re-assertion of these specific claims. The public record does not disclose whether Multimedia Technologies intends to appeal, nor does it reveal the damages quantum originally sought.

901 days — above the median for E.D. Tex. patent cases reaching jury trial
Jury verdict for LG: no infringement and invalidity on all asserted claims
Dual verdict: non-infringement plus invalidity
A jury finding of both non-infringement and invalidity is the most complete outcome a defendant can achieve at trial. Non-infringement alone would leave the patents intact for future enforcement against others; invalidity extinguishes the asserted claims entirely. LG secured both findings on all five asserted claims, eliminating any residual liability risk on these specific patent claims and undermining their value for assertion against other TV manufacturers.
Complete defence verdictAll asserted claims invalidated — enforcement value destroyed
Multimedia Technologies loses not only this action but the enforceability of the five asserted claims. An invalidity verdict entered as judgment under Rule 58 carries estoppel weight that substantially bars re-litigation of those claims. The cost award against plaintiff adds financial exposure on top of the substantive loss. Any remaining patents in the portfolio that were not asserted — or whose claims were not tried — are unaffected by this verdict on their face.
Claims invalidated; costs awarded to LGLG prevails on every front — cost recovery ordered
LG Electronics emerges with a clean record on the asserted claims and a court order designating it the prevailing party entitled to recover costs under 28 U.S.C. § 1920. The verdict protects LG’s smart TV platform — including its webOS interface, panel navigation, and VOD delivery systems — from further challenge under these specific claims. LG’s defence team from Morgan Lewis & Bockius and ArentFoxSchiff successfully argued both non-infringement and invalidity before the jury.
Prevailing party; Bill of Costs orderedSmart TV UI patent risk recalibrated for the sector
This verdict signals that broadly drafted smart TV interface patents — covering panel management, global navigation, and VOD delivery — face significant invalidity risk when litigated to trial in E.D. Tex. Competitors operating smart TV ecosystems, including Roku, Samsung, and Amazon Fire TV, may draw comfort from the invalidity findings. Patent assertion entities holding similar portfolios of smart TV UI patents should expect heightened scrutiny of claim scope in any future enforcement action.

Official order — verbatim text
The jury’s unanimous verdict finding both non-infringement and invalidity on all five asserted claims represents the broadest possible defendant victory at trial. The phrasing ‘do not infringe’ and ‘each of the Asserted Claims were invalid’ leaves no partial win for the plaintiff. Under Federal Circuit precedent, an invalidity finding entered as a Rule 58 judgment carries issue preclusion effect, substantially foreclosing re-litigation of these specific claims. The court’s immediate cost award designation reinforces the totality of LG’s victory and signals the court found the defence position well-founded across both substantive issues.
US9055254B2 — Smart TV panel management and UI navigation systems
The eleven patents asserted by Multimedia Technologies — anchored by US9055254B2 and US9055255B2, both originating from application filings in the 2013 timeframe — protect methods and systems for managing application panels, global navigation interfaces, live television overlays, and video-on-demand delivery on intelligent television platforms. These patents sit in the intersection of consumer electronics UI design and smart TV operating system architecture, a technology space that became commercially critical as OEMs competed to differentiate their connected TV ecosystems.
For LG, whose webOS platform powers millions of smart TVs globally, the asserted claims targeted core navigational and content-delivery features. The invalidity findings suggest the jury concluded that the underlying concepts were anticipated or obvious in light of prior art predating the patents’ priority dates — a significant outcome given the volume of smart TV UI innovation occurring in the 2010–2013 period from competitors including Samsung, Apple, Google, and Roku. This verdict weakens the broader enforceability signal of Multimedia Technologies’ remaining portfolio against other OEMs.
Should you run an FTO against US9055254B2 and the Multimedia Technologies portfolio?
Any company developing smart TV operating systems, application panel interfaces, content recommendation engines, or video-on-demand delivery platforms should assess exposure to the Multimedia Technologies patent family. While the five asserted claims have now been judicially invalidated, the eleven-patent portfolio contains additional claims and patents not tried in this action — including US9185325B2, US9426527B2, US9232168B2, US9578384B2, US9237291B2, and US9820003B2 — which remain of uncertain enforceability.

What this verdict signals for the smart TV and connected device IP landscape
A clean sweep for LG at trial reshapes the enforcement calculus for smart TV interface patents asserted in East Texas.
Invalidity findings on all claims raise the bar for similar UI patent assertions
When a jury invalidates every asserted claim across five patents in a single verdict, it signals that the prior art landscape for smart TV interface technology is well-developed. Companies operating in the connected TV space should audit their own IP positions against this prior art record — both offensively and defensively — before asserting or responding to similar claims.
E.D. Tex. jury trials remain high-stakes for patent holders — not just defendants
The Eastern District of Texas is often characterised as plaintiff-friendly, yet this unanimous defendant verdict demonstrates that technically sophisticated defendants with well-resourced counsel can prevail at trial. The 901-day timeline and breadth of the defence team suggest substantial litigation investment by LG — a cost that smaller defendants may not be able to replicate.
Multimedia v LG — key questions answered
The jury returned a unanimous verdict on May 23, 2025 finding that LG Electronics did not infringe any of the five asserted claims and that each asserted claim was invalid. The court entered judgment for LG on June 11, 2025, also ordering LG to recover its costs from the plaintiff.
Multimedia Technologies asserted claims from five patents at trial: US9055254B2 (claim 8), US9247174B2 (claims 10–11), US9510040B2 (claim 21), US10419805B2 (claim 10), and US9055255B2 (claim 19). All relate to smart TV user interface and video delivery systems. The broader complaint involved up to eleven patents in the same family.
The accused products and features included LG’s application panel manager, global panel interface, live television application overlay, data service, video-on-demand systems, and on-screen channel-change methods — all components of LG’s smart TV platform, understood to relate to its webOS operating system environment.
The five asserted claims are judicially invalidated, carrying issue preclusion effect against re-litigation of those specific claims. However, approximately six additional patents in the portfolio — including US9185325B2, US9426527B2, and US9820003B2 — were not reduced to asserted claims at trial and remain of uncertain enforceability. A detailed claim-mapping exercise is required to assess residual risk.
Yes, Multimedia Technologies may appeal the judgment to the United States Court of Appeals for the Federal Circuit. Post-trial motions under Rules 50(b) and 59 may also be filed in the district court first. The public record as of the judgment date does not disclose whether an appeal has been filed or is planned. Federal Circuit review of jury verdicts is deferential — reversal of a factual invalidity finding requires showing the verdict was not supported by substantial evidence.
