Philips v. MediaTek: § 101 Defeats Video IC Patents After Nearly 5 Years
Koninklijke Philips and Philips North America sued MediaTek over two patents covering digital video-capable integrated circuits. After 1,782 days of litigation in Delaware, the court entered judgment on the pleadings in favor of MediaTek, finding the asserted claims of US10298564B2 patent-ineligible under 35 U.S.C. § 101 — a ruling that applied across both related cases by stipulation.
§ 101 Ineligibility Ends Philips’ Digital Video IC Campaign in Delaware
Koninklijke Philips N.V. and Philips North America LLC filed suit against MediaTek Inc. and MediaTek USA Inc. in the District of Delaware on September 17, 2020, asserting infringement of two patents: US9590977B2 and US10298564B2. The accused products centered on MediaTek’s Mstar-branded MSD6886NQHT integrated circuit and associated firmware, which Philips alleged were incorporated into Hisense H65 Series Android TVs. The patents relate to digital video-capable integrated circuits — a core component in the smart TV and streaming device ecosystem.
The case resolved on August 4, 2025 when the court entered judgment on the pleadings in favor of MediaTek. The critical legal mechanism was a Rule 12(c) ruling entered on July 28, 2025 in the companion case No. 20-cv-01247 (Philips v. Realtek Semiconductor), which held the asserted claims of US10298564B2 patent-ineligible under 35 U.S.C. § 101. By stipulation of the parties, that order applied equally in this MediaTek case, resulting in judgment for the defendants without a separate § 101 hearing.
The nearly five-year duration suggests the case navigated substantial pretrial proceedings before reaching its § 101 resolution — a timeline consistent with claim construction disputes and inter partes review activity running in parallel. It is notable that the § 101 invalidity ruling came via judgment on the pleadings rather than at summary judgment or trial, suggesting the abstract idea or ineligibility defect was considered sufficiently clear on the face of the pleadings. The public record does not disclose the final status of US9590977B2 claims, whether Philips intends to appeal, or whether any licensing resolution was reached.

Judgment for MediaTek: what the § 101 ruling means for both parties
Rule 12(c) judgment on pleadings via § 101 ineligibility
A Rule 12(c) motion for judgment on the pleadings succeeds when no material facts are in dispute and the moving party is entitled to judgment as a matter of law. Here, the court found the asserted claims of US10298564B2 patent-ineligible under 35 U.S.C. § 101 — meaning they were directed to an abstract idea without an inventive concept sufficient to transform them into patent-eligible subject matter. Crucially, the stipulation mechanism extended this ruling to the MediaTek case without re-litigation.
§ 101 — abstract idea / Alice frameworkPhilips loses enforceability of key video IC claims
The § 101 ruling eliminates Philips’ ability to enforce the adjudicated claims of US10298564B2 against MediaTek and — as a practical matter — substantially weakens their licensing leverage over that patent in the broader digital video IC market. The status of US9590977B2 claims in this case is not expressly resolved in the published order, leaving some uncertainty. Philips retains the right to appeal to the Federal Circuit, but § 101 reversals at the appellate level are statistically uncommon.
Patent invalidated — § 101 ineligible claimsMediaTek secures full defense without trial
MediaTek obtained judgment in its favor at the pleadings stage — avoiding the substantial cost and risk of claim construction hearings, expert proceedings, and trial. The ruling, extended by stipulation from the Realtek companion case, reflects an efficient defensive strategy: coordinating with co-defendant Realtek to litigate shared invalidity issues once and apply the result across cases. This approach is consistent with how large semiconductor defendants manage multi-defendant Philips licensing campaigns.
Full defense — no liability finding§ 101 ruling raises the bar for digital video IC patent enforcement
A § 101 invalidity finding in Delaware on digital video integrated circuit patents signals heightened vulnerability for functionally claimed semiconductor IP across the Alice framework. Device makers, SoC suppliers, and TV OEMs incorporating similar integrated circuits should note that Philips’ enforcement campaign — which targeted Hisense-branded products incorporating MediaTek silicon — has now stalled at the subject matter eligibility stage. Companies operating in adjacent video processing and smart TV supply chains should assess whether similar claims in their licensing exposure have analogous § 101 vulnerabilities.

Official order — verbatim text
The order entered August 4, 2025 applied a Rule 12(c) judgment on the pleadings — specifically a § 101 subject matter ineligibility ruling from the companion Realtek case — to MediaTek by stipulation. The phrasing ‘judgment on the pleadings is entered in favor of Defendants and against Plaintiff’ represents a final merits-based disposition: the asserted claims of US10298564B2 were found directed to patent-ineligible subject matter under 35 U.S.C. § 101 without reaching infringement or damages. This is a defendant win on invalidity grounds, not a procedural dismissal, and carries full preclusive effect as to those claims.
US9590977B2 & US10298564B2 — Digital Video Integrated Circuit Patents
US9590977B2 (application no. US15/229207) and US10298564B2 (application no. US16/117019) both relate to digital video-capable integrated circuits and associated firmware. US10298564B2 was the patent whose asserted claims were adjudicated patent-ineligible under § 101, with the court finding them directed to an abstract idea under the Alice/Mayo framework. These patents sit within Philips’ broad portfolio targeting the digital video processing and smart TV silicon supply chain, covering functionality implemented in system-on-chip and standalone integrated circuit designs.
Philips has historically deployed its video IC and signal processing patent portfolio in coordinated multi-defendant campaigns targeting semiconductor suppliers and their downstream OEM customers. The strategic value of these patents lay in their position in the Android TV and digital video device supply chain — where a single IC design (here, the Mstar MSD6886NQHT) may be incorporated into millions of consumer devices. The § 101 ruling on US10298564B2 significantly weakens Philips’ enforcement leverage in this technology area and may prompt broader portfolio reassessment for similarly structured video processing claims.
Should you run an FTO against US9590977B2 and US10298564B2?
Any company designing, sourcing, or integrating digital video-capable integrated circuits — including SoC vendors, Android TV OEMs, firmware developers, and streaming device makers — should assess freedom-to-operate against both patents. While US10298564B2 claims have been ruled ineligible in this case, the ruling may not automatically bind third parties in separate proceedings. US9590977B2 remains an active consideration. Companies using MediaTek, Mstar, or competing video IC platforms in consumer devices should not assume blanket clearance without a formal claim-level analysis.
PatSnap Eureka’s FTO Search Agent can map the claim scope of US9590977B2 and US10298564B2 against your product’s technical architecture, flag prior art that may support further § 101 or § 102 challenges, and surface related Philips family members that may cover the same or adjacent functionality. For supply chain teams sourcing video ICs for smart TV applications, Eureka can also identify whether comparable § 101 challenges have been raised against sibling patents in parallel litigations or IPR proceedings.

What this case signals for the digital video semiconductor IP landscape
A § 101 defeat for Philips after five years shapes how video IC patent campaigns are structured and defended going forward.
Stipulation strategy: co-defendants can share § 101 rulings across cases
MediaTek and Realtek coordinated to apply a single § 101 ruling across parallel Philips cases by stipulation. This approach — litigating a common invalidity issue once and extending it — is a cost-efficient model for semiconductor defendants facing multi-case licensing campaigns. IP counsel for any company named alongside others in a Philips enforcement action should assess whether a joint § 101 strategy is viable.
Rule 12(c) is an underused weapon against functionally claimed video IC patents
The court resolved § 101 ineligibility at the pleadings stage — before claim construction and before expert reports. For digital video and smart TV semiconductor defendants, this signals that well-pleaded § 101 defenses based on abstract idea doctrine may succeed early. Defendants should assess Alice step-one arguments for functionally defined signal processing and video IC claims at the outset, not as a fallback strategy.
Philips v Mediatek — key questions answered
The Delaware District Court entered judgment on the pleadings in favor of MediaTek on August 4, 2025. The ruling was based on a § 101 patent ineligibility finding — entered first in the companion case Philips v. Realtek (No. 20-cv-01247) on July 28, 2025 — which the parties stipulated applied equally to the MediaTek case. The asserted claims of US10298564B2 were held patent-ineligible under 35 U.S.C. § 101.
Philips asserted two patents: US9590977B2 (application US15/229207) and US10298564B2 (application US16/117019). Both relate to digital video-capable integrated circuits and associated firmware. The § 101 ruling adjudicated in the companion Realtek case — and applied here by stipulation — expressly addressed US10298564B2. The public order does not separately resolve the status of US9590977B2 claims in this specific case.
Philips accused MediaTek’s Mstar-branded MSD6886NQHT integrated circuit and associated firmware, specifically as incorporated into the Hisense H65 Series Android TV (Model 43H6570G). The broader accused product category was digital video-capable integrated circuits and associated firmware for inclusion in digital video-capable devices — suggesting the potential for a wider product scope beyond the specifically named Hisense TV model.
A Rule 12(c) judgment on the pleadings under 35 U.S.C. § 101 is a merits ruling that the asserted patent claims are directed to patent-ineligible subject matter — typically an abstract idea, law of nature, or natural phenomenon — without a sufficient inventive concept. It is not a procedural dismissal. The ruling carries full preclusive effect against Philips for those claims as against MediaTek, and substantially weakens the commercial licensing value of those claims in the broader market.
The § 101 ineligibility ruling entered in Philips v. Realtek Semiconductor Corp. (Case No. 20-cv-01247-CFC) on July 28, 2025 was applied to the MediaTek case by virtue of a pre-existing stipulation between the parties and a court order (D.I. 196). This means MediaTek obtained the benefit of Realtek’s successful § 101 motion without having to independently litigate the same issue — an efficient outcome consistent with coordinated multi-defendant patent defense strategies.
