Philips v. Intel: §101 Invalidity Ends 1,904-Day Content-Protection Patent Dispute
Koninklijke Philips and Philips North America sued Intel Corporation in Delaware, asserting two content-protection patents against Intel’s Core processor generations and NUC product lines. After plaintiff rights transferred to Media Content Protection LLC, Intel secured summary judgment invalidating both patents under §101 — ending over five years of litigation without a single damages award.
Content-Protection Patents Fall to §101 After Five-Year Delaware Battle
On September 17, 2020, Koninklijke Philips N.V. and Philips North America LLC filed suit in the U.S. District Court for the District of Delaware against Intel Corporation, alleging infringement of U.S. Patent No. 9,436,809 and U.S. Patent No. 10,091,186 — both directed to digital content protection technology. The accused products spanned Intel’s 6th through 10th Generation Core processors (Skylake through Ice Lake), NUC Boards, NUC Kits, NUC Mini PCs, and associated firmware, making this a commercially broad assertion targeting Intel’s mainstream processor portfolio.
In a notable mid-litigation development, the parties stipulated in August 2024 to substitute Media Content Protection LLC (MCP) as the plaintiff, suggesting an assignment or licensing restructuring of the asserted patents. On November 25, 2025, the Court granted Intel’s motion for summary judgment of invalidity, holding that all asserted claims of both the ‘186 and ‘809 patents fail under 35 U.S.C. §101 as patent-ineligible subject matter. Final judgment was entered on December 4, 2025, in Intel’s favor on both MCP’s infringement counts and Intel’s invalidity counterclaims, while Intel’s remaining defenses and counterclaims were dismissed without prejudice.
The case’s duration — over five years from filing to final judgment — likely reflects the complexity of §101 subject-matter eligibility analysis applied to content-protection claim architecture, as well as the mid-case plaintiff substitution. The §101 invalidity ruling is significant: it disposes of both patents on threshold eligibility grounds without reaching claim construction, infringement, or damages, meaning the public record does not reveal which specific claim limitations were most vulnerable. Costs and attorneys’ fees remain unresolved pending any appeal by MCP.

Intel wins on §101: what the invalidity ruling means for both parties
§101 invalidity: patents fail at the threshold eligibility gate
Under 35 U.S.C. §101, a patent claim is invalid if it is directed to an abstract idea, law of nature, or natural phenomenon without adding an inventive concept that transforms it into patent-eligible subject matter (Alice/Mayo framework). A §101 ruling on summary judgment means the Court found the asserted claims legally ineligible without resolving infringement or claim construction — the most cost-efficient path to dismissal for defendants in software-adjacent patent cases.
Alice/Mayo §101 frameworkBoth patents invalidated — MCP loses its entire enforcement position
The final judgment strips MCP (the substituted plaintiff) of any enforceable rights in the ‘809 and ‘186 patents against Intel. Because the ruling is on §101 patent eligibility — a question of law — it carries persuasive weight in any future enforcement attempt against other defendants in other forums. MCP retains the right to appeal, but overturning a §101 summary judgment at the Federal Circuit faces a historically high bar, particularly for content-protection and signal-processing claim architectures.
Both patents eliminatedIntel’s processor and NUC portfolio cleared of these patent claims
Intel’s 6th through 10th Generation Core processors, NUC product families, and associated firmware are no longer exposed to infringement liability under the ‘809 or ‘186 patents. Intel’s counterclaims of invalidity were also resolved in its favour. Remaining defences and counterclaims were dismissed without prejudice, preserving Intel’s options if litigation is revived. Cost and fee recovery remains live, with Intel holding a 30-day window post-appeal resolution to file its motions.
Full processor portfolio cleared§101 ruling raises the bar for content-protection patent enforcement in silicon
This outcome is consistent with a broader pattern of content-protection and DRM-adjacent patents being invalidated under Alice in Delaware and the Federal Circuit. Competitors and licensees operating in the content-security and processor firmware space should note that claim architectures framed around access control, authentication, or media protection protocols face heightened §101 scrutiny. Patent portfolios in this domain may require re-examination of claim drafting strategies to survive eligibility challenges.

Official order — verbatim text
The Court’s final judgment resolves both MCP’s infringement counts and Intel’s invalidity counterclaims in Intel’s favour based on a §101 subject-matter eligibility determination — a purely legal ruling that bypasses infringement analysis entirely. The phasing of the order — entering judgment on both parties’ primary claims while dismissing remaining Intel counterclaims without prejudice — is a standard Delaware practice preserving Intel’s fallback positions. The deferral of costs and fee motions until post-appeal resolution reflects judicial economy, leaving open a potentially significant §285 proceeding should MCP’s appeal fail or lapse.
US10091186B2 & US9436809B2 — Digital Content Protection Technology
U.S. Patent No. 10,091,186 (application no. 15/352,646) and U.S. Patent No. 9,436,809 (application no. 14/538,493) are both directed to digital content protection technology — covering methods and systems for controlling access to and distribution of media content across processor-based computing platforms. Both patents originated with Koninklijke Philips N.V., a long-standing innovator in consumer electronics and digital media standards, before rights were assigned to Media Content Protection LLC during this litigation. The Court’s §101 ruling indicates the claims were characterised as abstract methods of organising or controlling information, without a sufficiently inventive technical implementation to survive the Alice two-step analysis.
These patents were asserted against some of Intel’s highest-volume commercial products — Core processor generations spanning 2015 to 2019 silicon — signalling that Philips and subsequently MCP believed the claimed content-protection methods were deeply embedded in mainstream compute architectures. For the semiconductor and connected device sector, §101 invalidation of content-protection patents framed as method claims is now a significant precedent: competitors developing DRM, secure boot, firmware authentication, or media-access-control features should audit their own patent portfolios and third-party licences for comparable eligibility risk.
Should your team run an FTO against US10091186B2 and US9436809B2?
Product teams building Intel-compatible platforms, NUC-form-factor embedded systems, or firmware integrating content-protection and DRM protocols should take note. Although both patents have been invalidated under §101, the ruling is subject to appeal — meaning enforceability could technically be restored. Any company designing media-access-control, secure content delivery, or authenticated firmware layers into processor-based products should validate that their architecture does not fall within the claim scope of these or related Philips/MCP family members still in force.

Intel’s §101 win over five years of litigation reveals durable lessons for patent holders and product teams in the semiconductor and DRM space.
§101 remains a decisive weapon against software-method content-protection claims
Intel’s success invalidating both patents on eligibility grounds — without reaching infringement — confirms that content-protection and access-control patent claims framed as abstract software methods remain highly vulnerable under Alice. IP teams asserting or defending such patents should assess §101 exposure before committing to multi-year litigation.
Plaintiff substitution mid-litigation signals portfolio monetisation complexity
The August 2024 substitution of Media Content Protection LLC for Philips as plaintiff suggests a patent assignment or licensing restructuring during active litigation. This type of mid-case transfer can affect litigation strategy, settlement leverage, and appellate standing — and is increasingly common in large-portfolio IP monetisation campaigns.
Philips v Intel — key questions answered
Intel Corporation won. On November 25, 2025, the Delaware District Court granted Intel’s motion for summary judgment, invalidating all asserted claims of U.S. Patent Nos. 9,436,809 and 10,091,186 under 35 U.S.C. §101. Final judgment was entered December 4, 2025 in Intel’s favour on all infringement and invalidity counts.
The accused products included Intel’s 6th through 10th Generation Core processors (Skylake, Kaby Lake, Coffee Lake, Coffee Lake Refresh, and Ice Lake), later-generation processors, NUC Boards, NUC Kits, NUC Laptop Kits, NUC Mini PCs, and associated firmware — covering a broad swath of Intel’s consumer and commercial compute portfolio.
The Court applied the Alice/Mayo two-step framework and found that the asserted claims of both the ‘809 and ‘186 patents are directed to patent-ineligible subject matter under 35 U.S.C. §101. The precise claim-by-claim analysis is set out in the Court’s November 25, 2025 order (D.I. 281, 282); the public verdict indicates all asserted claims failed at summary judgment without reaching infringement.
The parties stipulated in August 2024 to substitute Media Content Protection LLC (MCP) for Koninklijke Philips N.V. and Philips North America LLC as plaintiff (D.I. 75, 78). This suggests an assignment of the asserted patents to MCP, consistent with patent monetisation or portfolio restructuring strategies, though the specific commercial terms are not disclosed in the public record.
No. The December 4, 2025 final judgment expressly defers any cost assessment and attorneys’ fee motions — including under Fed. R. Civ. P. 54(d) and Local Rules 54.1 and 54.3 — until 30 days after resolution of the last appeal. If MCP does not appeal, Intel’s deadline to file fee motions and bills of costs is extended to 30 days after MCP’s appeal deadline lapses.
