MediaPointe & AMHC v. Akamai: Federal Circuit Affirms CDN Patents Unpatentable
MediaPointe, Inc. and AMHC, Inc. asserted two patents covering content delivery network technology against Akamai Technologies. After 621 days, the Court of Appeals for the Federal Circuit affirmed both patents unpatentable — extinguishing enforcement rights at the appellate level.
Federal Circuit ends MediaPointe’s CDN patent campaign against Akamai
MediaPointe, Inc. and co-plaintiff AMHC, Inc. brought an invalidity/cancellation action asserting two patents — US8559426B2 and US9426195B2 — directed at content delivery network technology against Akamai Technologies, Inc., one of the world’s leading CDN providers. The appeal was docketed at the Federal Circuit on 14 March 2024, challenging a prior ruling on the patentability of the asserted claims.
On 25 November 2025, the Federal Circuit issued a final order affirming the finding of unpatentability across both patents. Affirmance at the Federal Circuit means the court found no reversible error in the lower tribunal’s determination — the patents stand cancelled, and Akamai faces no further liability exposure from these specific claims. The appellate record is now closed at this level.
The 621-day duration is broadly consistent with Federal Circuit appeal timelines for patent validity disputes. The unpatentability basis of termination suggests the underlying tribunal — likely the Patent Trial and Appeal Board — had already invalidated the claims, and the Federal Circuit declined to disturb that outcome. What drove the specific invalidity rationale, and whether any dependent claims survived, remains undisclosed in the public record.

Federal Circuit affirms: what the unpatentability ruling means for both parties
Affirmance means the Federal Circuit found no reversible error below
When the Federal Circuit affirms, it is not issuing a fresh ruling on patentability — it is concluding that the lower tribunal applied the correct legal standards and reached a supportable conclusion. Both US8559426B2 and US9426195B2 were found unpatentable, and that determination now carries full appellate endorsement. No further appeal lies within the Federal Circuit system at this level.
Appellate affirmance — no reversible errorMediaPointe and AMHC lose enforceability of both CDN patents
Affirmance of unpatentability means both asserted patents are cancelled — MediaPointe and AMHC cannot enforce US8559426B2 or US9426195B2 against Akamai or any third party. With the Federal Circuit having affirmed, the appellants’ remaining option would be a petition for certiorari to the Supreme Court, which is granted in only a small fraction of patent cases and typically on questions of broad legal significance.
Both patents cancelled and unenforceableAkamai’s CDN system cleared — patents cannot be re-asserted
For Akamai Technologies, Federal Circuit affirmance of unpatentability provides strong commercial protection. The cancelled patents cannot be asserted against Akamai’s content delivery network in future litigation. The appellate win also raises the bar for any related patent family claims MediaPointe or AMHC might attempt to assert, as the invalidity reasoning from the lower tribunal now has appellate backing.
Akamai CDN cleared of liabilityCDN sector: affirmed unpatentability strengthens operating freedom
An affirmed unpatentability finding on CDN architecture patents benefits the broader market — competitors and cloud providers operating in the content delivery space can treat these specific claim families as no longer posing enforcement risk. However, companies should audit related continuation or divisional patents from the same families, as those may remain in force and could be deployed in follow-on enforcement campaigns by the same plaintiffs or assignees.

Official order — verbatim text
The Federal Circuit’s order — ‘THIS CAUSE having been considered, it is ORDERED AND ADJUDGED: AFFIRMED’ — is a full affirmance on the merits, with unpatentability as the stated basis of termination. At the Federal Circuit, affirmance of a PTAB unpatentability determination typically requires the appellant to show the board committed legal error or that its factual findings lacked substantial evidence support — a demanding standard. The terse order language suggests no partial dissent or remand on any claim subset, indicating the court found the invalidity record sufficient across all challenged claims of both patents.
US8559426B2 & US9426195B2 — Content Delivery Network Architecture Patents
US8559426B2 (application no. US09/936624) and US9426195B2 (application no. US14/023435) both cover technology in the content delivery network domain. US8559426B2 originates from an earlier application series suggesting a foundational filing, while US9426195B2 carries a later application number consistent with a continuation or related filing in the same family. Both patents were asserted against Akamai’s CDN system, which routes and delivers web content at scale for enterprise customers globally.
CDN patents occupy a commercially sensitive zone — Akamai’s core business depends on the infrastructure these claims purported to cover. The Federal Circuit’s affirmance of unpatentability removes these specific claims from the enforcement landscape permanently, but the strategic significance extends beyond this case: any company operating distributed content delivery infrastructure should treat this outcome as confirmation that well-prepared PTAB challenges can successfully neutralise even foundational CDN patent assertions at the highest appellate level.
Should you run an FTO against US8559426B2 and US9426195B2?
Both patents have been affirmed unpatentable by the Federal Circuit — they no longer pose a direct enforcement risk. However, R&D and product teams building or deploying CDN infrastructure, edge computing, or distributed content delivery systems should still conduct FTO analysis across the broader MediaPointe and AMHC patent portfolio. Related continuation or divisional applications from the same priority chains may remain active and could cover overlapping technical territory.
PatSnap Eureka’s FTO Search Agent allows you to map the full patent family landscape around US8559426B2 and US9426195B2 — identifying surviving continuations, related assignee filings, and claim scope across jurisdictions. For CDN and cloud infrastructure teams, this is particularly valuable before launching new edge delivery architectures or entering licensing negotiations where these cancelled patents might still be referenced as prior art or family context.

Cases involving content delivery network patents challenged at the Federal Circuit, particularly through PTAB invalidity proceedings, share key procedural and strategic patterns with this dispute.
What this case signals for the CDN and cloud infrastructure IP landscape
The Federal Circuit’s affirmance adds to a growing body of appellate precedent constraining CDN-related patent claims challenged via PTAB proceedings.
PTAB-to-Federal Circuit pipeline remains a powerful defence tool for CDN operators
This outcome is consistent with a pattern where large CDN and cloud infrastructure defendants successfully use inter partes review or similar PTAB proceedings to cancel asserted patents, then defend that outcome at the Federal Circuit. Companies facing CDN patent assertions should evaluate PTAB filing windows early — the appellate affirmance rate for PTAB unpatentability findings is historically high.
Akamai’s WilmerHale defence team secured a clean appellate record
Akamai was represented by WilmerHale, a firm with a strong Federal Circuit track record. The clean affirmance — without remand or partial reversal — suggests the invalidity record below was well-constructed. Patent holders asserting against well-resourced CDN defendants should anticipate a fully-litigated PTAB record that will be difficult to disturb on appeal.
MEDIAPOINTE v Akamai — key questions answered
The Federal Circuit affirmed the finding of unpatentability for both US8559426B2 and US9426195B2 on 25 November 2025. The court found no reversible error in the lower tribunal’s determination, leaving both patents cancelled and unenforceable against Akamai’s content delivery network system.
Two patents were at issue: US8559426B2 (application no. US09/936624) and US9426195B2 (application no. US14/023435). Both relate to content delivery network technology and were asserted against Akamai’s CDN system. The Federal Circuit affirmed both unpatentable.
Affirmance of unpatentability means the asserted patents are permanently cancelled. Akamai cannot face further litigation on these specific claims. The ruling also strengthens Akamai’s position if related continuation patents from the same families are later asserted, as the invalidity reasoning now carries Federal Circuit endorsement.
The Federal Circuit reviews PTAB legal conclusions de novo and factual findings — such as whether prior art anticipates or renders a claim obvious — under the substantial evidence standard. Appellants must show either legal error or that the factual record lacked sufficient evidence to support the PTAB’s finding. This is a demanding standard, which likely contributed to the affirmance outcome in this case.
The affirmance directly cancels the two asserted patents. However, continuation, divisional, or continuation-in-part applications sharing priority with US8559426B2 or US9426195B2 are not automatically invalidated. Companies operating CDN infrastructure should conduct a full patent family search to identify any surviving related applications that MediaPointe or AMHC may still hold.
