Nielsen v. VideoAmp: Infringement Complaint Dismissed With Prejudice in Delaware
The Nielsen Company filed a patent infringement action against VideoAmp in Delaware federal court, asserting two patents covering methods to determine media presentation duration from tuning session data. Judge Richard G. Andrews granted VideoAmp’s motion to dismiss with prejudice — ending Nielsen’s claims entirely in 425 days without reaching trial.
Nielsen’s Media Measurement Patents Extinguished at the Pleadings Stage
On January 31, 2024, The Nielsen Company (US), LLC filed suit against VideoAmp, Inc. in the U.S. District Court for the District of Delaware (Case No. 1:24-cv-00123), asserting infringement of US11871058B2 and US11856250B2. Both patents relate to methods and apparatus for determining the duration of media presentations based on tuning session duration — a technically significant capability in the competitive audience measurement and media analytics sector.
VideoAmp moved to dismiss early in the proceedings, and Judge Richard G. Andrews granted that motion, dismissing the complaint with prejudice. A dismissal with prejudice is a final adjudication on the merits for procedural purposes: Nielsen cannot refile the same claims against VideoAmp in federal court. The accompanying Memorandum Opinion, referenced in the order, contains the court’s substantive reasoning, which is authoritative for understanding the legal basis of the outcome.
The case resolved in approximately 14 months and before discovery commenced, suggesting VideoAmp identified a threshold legal deficiency in Nielsen’s complaint — potentially directed to patent eligibility under 35 U.S.C. § 101, claim specificity, or pleading standards. The exact basis is stated in the Memorandum Opinion. What is notable publicly is that Nielsen, a dominant incumbent in audience measurement, was unable to sustain its infringement pleading against an upstart competitor, which may carry strategic significance for ongoing IP enforcement in this sector.

Dismissed with prejudice: what the ruling means for both parties
Motion to dismiss granted — complaint fails as a matter of law
A Rule 12(b)(6) motion to dismiss tests whether the complaint states a legally sufficient claim. Granting it with prejudice means the court found the deficiency to be unredeemable — amendment would not cure the legal flaw. The accompanying Memorandum Opinion controls the precise rationale. This is a high bar for a defendant to clear at this early stage, and suggests a structural weakness in Nielsen’s pleading.
Resolved at pleadings — no discoveryNielsen’s claims permanently extinguished against VideoAmp
Dismissal with prejudice bars Nielsen from asserting the same claims under US11871058B2 and US11856250B2 against VideoAmp in federal district court. Unlike a without-prejudice dismissal, there is no opportunity to refile and cure the complaint. Nielsen could potentially appeal the dismissal to the Federal Circuit, but the threshold for reversal of a district court’s with-prejudice dismissal is meaningful. The patents themselves remain in force and Nielsen may assert them against other parties.
Cannot refile — appeal remains openVideoAmp secures full dismissal without reaching merits of infringement
VideoAmp achieved the strongest possible pre-trial outcome: a with-prejudice dismissal that terminates Nielsen’s infringement claims entirely. VideoAmp’s counsel at Fish & Richardson secured this result without exposure to discovery or claim construction proceedings. This ruling insulates VideoAmp from these specific patent claims in this forum, though the underlying validity and scope of Nielsen’s patents are not adjudicated — they remain live questions in other contexts.
Full dismissal — no infringement findingIP enforcement limits in media measurement tech exposed
This outcome is consistent with a broader pattern of courts scrutinising software-implemented measurement patents at the pleadings stage. For the media analytics and audience measurement sector, it signals that patent assertions against emerging competitors must be grounded in pleading-proof specificity. Nielsen’s inability to sustain its complaint against VideoAmp — a direct commercial rival — may embolden other measurement platforms to contest similar assertions early and aggressively.

Official order — verbatim text
The order’s language — ‘DISMISSED with prejudice’ following grant of VideoAmp’s Motion to Dismiss — confirms this is a terminal, court-initiated adjudication, not a settlement or voluntary withdrawal. The reference to an accompanying Memorandum Opinion indicates the court issued substantive reasoning, which will govern the legal basis. For both parties, the binding effect is clear: Nielsen’s infringement claims under these two patents are foreclosed in this court as against VideoAmp, and no amended complaint is permitted.
US11871058B2 & US11856250B2 — Media Presentation Duration Measurement
US11871058B2 (application US17/898185) and US11856250B2 (application US17/967832) are Nielsen patents directed to methods and apparatus for determining the duration of media presentations using tuning session duration data. These patents sit at the intersection of audience measurement infrastructure and data analytics — covering the technical process by which viewership duration is computed from raw tuning signals, a foundational capability in any media ratings or advertising attribution system.
Strategically, these patents represent Nielsen’s attempt to assert proprietary protection over core audience measurement workflows against VideoAmp, which has positioned itself as a next-generation alternative to Nielsen’s panel-based ratings. The assertion of two related patents on the same product category suggests a portfolio enforcement approach. However, the with-prejudice dismissal indicates the pleading-level articulation of infringement was insufficient — raising questions about how broadly these patents can be asserted against competing measurement methodologies in future litigation.
Should you run an FTO against US11871058B2 and US11856250B2?
Any company developing or commercialising software or systems that compute media viewing duration from tuning session data — including streaming analytics platforms, set-top-box data aggregators, ACR (automatic content recognition) vendors, and advertising attribution tools — should assess exposure under these Nielsen patents. The dismissal in this case does not limit Nielsen’s enforcement rights against third parties. Both patents remain active and potentially asserted.
PatSnap Eureka’s FTO Search Agent can map the claim scope of US11871058B2 and US11856250B2 against your product architecture, identify prior art that may support invalidity arguments, and flag related Nielsen family members that could extend the risk footprint. R&D and product teams building tuning-session or media-duration analytics should initiate an FTO assessment before product launch or commercial scaling.

What this case signals for the media measurement IP landscape
A with-prejudice dismissal at the pleadings stage is a rare and decisive outcome — here is what it means for IP strategy in audience analytics.
With-prejudice dismissals reward early, aggressive motion practice
VideoAmp’s success on a motion to dismiss demonstrates that defendants in software-implemented media measurement cases should scrutinise complaints immediately for § 101 eligibility, pleading specificity, and claim mapping deficiencies. Investing in early motion practice can end exposure entirely before discovery costs accumulate.
Nielsen’s patents survive — enforcement risk remains for other market players
US11871058B2 and US11856250B2 remain in force. The dismissal is procedural and does not invalidate the patents or limit Nielsen’s ability to assert them against other audience measurement and analytics platforms. Competitors offering media duration measurement capabilities should assess FTO exposure now.
The v Videoamp — key questions answered
Nielsen filed a patent infringement complaint against VideoAmp in Delaware federal court on January 31, 2024, asserting US11871058B2 and US11856250B2. Judge Richard G. Andrews granted VideoAmp’s motion to dismiss with prejudice on March 31, 2025, terminating Nielsen’s claims entirely. The court issued a Memorandum Opinion with its substantive reasoning.
A dismissal with prejudice means Nielsen cannot refile the same infringement claims against VideoAmp in federal district court. However, the patents themselves remain valid and in force. Nielsen retains the right to assert these patents against other defendants, and may appeal the dismissal to the Federal Circuit.
The court’s order references an accompanying Memorandum Opinion as the source of its reasoning. The public order does not specify the exact legal basis. In Delaware patent cases, with-prejudice dismissals at the pleading stage are commonly associated with patent eligibility challenges under 35 U.S.C. § 101, or failures to adequately plead direct or indirect infringement, but the specific basis here requires review of the Memorandum Opinion.
Yes. A final judgment of dismissal with prejudice is an appealable order. Nielsen could seek review before the U.S. Court of Appeals for the Federal Circuit, which has exclusive appellate jurisdiction over patent cases. The Federal Circuit would review the district court’s legal conclusions de novo, meaning no deference is owed to Judge Andrews’ interpretation of law.
Both patents cover methods and apparatus for determining the duration of media presentations based on tuning session duration data. This technology is foundational to audience measurement systems — computing how long a viewer watched specific content using tuning signals, which underpins ratings, advertising attribution, and content analytics platforms across broadcast, cable, and streaming environments.
