Rich Media Club v. Duration Media: Ad Viewability Patent Dismissed With Prejudice
Rich Media Club asserted US11741482B2 — a patent covering ad viewability technology — against Duration Media’s HVAX and VaaS products in the Arizona District Court. After 552 days of litigation, both parties agreed to a stipulated dismissal with prejudice, each bearing its own costs and attorneys’ fees.
A Stipulated Exit From an Ad-Tech Viewability Patent Battle
Rich Media Club, LLC filed suit against Duration Media, LLC on 19 September 2023 in the United States District Court for the District of Arizona (Case No. 2:23-cv-01967), asserting infringement of US11741482B2. The accused products were Duration Media’s Highly Viewable Ad Exchange (HVAX) and its Viewability as a Service (VaaS) offerings — both squarely within the digital advertising viewability sector that the asserted patent purports to protect.
The case concluded on 24 March 2025, when Judge Steven P. Logan entered an order granting the parties’ Stipulation of Dismissal (Doc. 62), dismissing the action with prejudice in its entirety. A with-prejudice dismissal by stipulation extinguishes the claims permanently — Rich Media Club cannot re-file the same infringement allegations against Duration Media based on the same patent and accused products. Notably, no fee-shifting was awarded; each party bears its own costs and attorneys’ fees, which is consistent with a negotiated resolution rather than a merits judgment.
The 552-day duration suggests the parties engaged in substantive pre-trial proceedings before reaching their agreement — long enough for claim construction and discovery to have shaped the parties’ risk assessments, yet short enough to avoid full trial preparation costs. The precise terms of any underlying business arrangement or license remain undisclosed in the public record. What drove the settlement — claim construction risk, prior art exposure, or commercial pragmatism — cannot be determined from the docket alone.

Dismissed with prejudice by stipulation: what the order means for both parties
Stipulated dismissal with prejudice bars all future re-filing
A dismissal with prejudice entered on the parties’ stipulation is a final adjudication on the merits for claim-preclusion purposes, even though no judge ruled on the substance of infringement. Rich Media Club permanently surrenders its right to assert the same patent claims against Duration Media’s HVAX and VaaS products. This is a stronger termination than a without-prejudice dismissal, which would leave the door open to re-filing.
Claim-preclusive dismissalRich Media Club exits with US11741482B2 intact but claims foreclosed against Duration Media
The patent itself remains valid and enforceable against third parties — the dismissal affects only Rich Media Club’s claims against this specific defendant. However, by agreeing to a with-prejudice exit with no costs awarded, Rich Media Club signals it could not or chose not to pursue a damages judgment. The patent’s enforceability against other HVAX-style ad exchanges in the market is unaffected by this order.
Patent survives; enforcement ended hereDuration Media secures permanent protection from this specific infringement action
Duration Media achieves certainty: it cannot face a second suit from Rich Media Club on US11741482B2 for the same accused products. The symmetric cost-bearing clause suggests neither party extracted a clear concession from the other. Duration Media’s HVAX and VaaS products remain commercially operational, though the underlying viewability technology may still be subject to scrutiny from other patent holders in this competitive space.
Permanent bar on re-suitAd viewability patent risk remains live across the broader market
This resolution does not invalidate US11741482B2 or narrow its claims — it simply ends one enforcement action. Other ad-tech platforms offering viewability measurement or guaranteed-viewability inventory should treat this patent as still enforceable. The case’s trajectory — filed, litigated for roughly 18 months, then quietly settled — is consistent with a technology licensing dispute resolved through negotiation rather than a clear legal win for either side.

Official order — verbatim text
The court’s order tracks the parties’ stipulation precisely, granting dismissal with prejudice across all claims and explicitly ordering each party to bear its own costs and attorneys’ fees. The with-prejudice designation is legally significant: it functions as a final judgment on the merits for claim-preclusion purposes, permanently barring Rich Media Club from reasserting US11741482B2 against Duration Media’s HVAX and VaaS products. The symmetric cost allocation is the only financial term visible in the public record and is consistent with a negotiated resolution rather than a concession by either party.
US11741482B2 — Ad Viewability and Highly Viewable Ad Exchange Technology
US11741482B2 (application number US17/961952) covers technology in the digital advertising viewability space — the suite of methods and systems used to guarantee, measure, or optimise whether digital ads are actually seen by users. Viewability has become a core currency in programmatic advertising, and patents protecting the mechanisms for guaranteed-viewable inventory or viewability-measurement-as-a-service occupy a commercially significant niche. The patent’s issuance as a granted US utility patent (B2 designation) confirms it survived substantive USPTO examination.
For the ad-tech sector, US11741482B2 represents a potential blocking position over platform architectures that combine an ad exchange with integrated viewability guarantees — precisely the model commercialised by Duration Media’s HVAX and VaaS products. Rich Media Club’s willingness to litigate for 18 months before settling suggests the patent was considered substantively assertable. Competitors building similar guaranteed-viewability or viewability-measurement platforms should assess whether their architectures fall within the claim scope before entering or scaling in this product category.
Should you run an FTO against US11741482B2 before launching a viewability platform?
Any ad-tech company developing, acquiring, or scaling a highly viewable ad exchange, viewability-as-a-service offering, or guaranteed-viewable inventory product should treat US11741482B2 as a priority FTO target. The Rich Media Club v. Duration Media case demonstrates that this patent has been actively asserted against a direct commercial competitor. The with-prejudice dismissal resolves only that specific dispute — it does not limit Rich Media Club’s ability to pursue the same claims against other market participants.
PatSnap Eureka’s FTO Search Agent can map US11741482B2’s claim scope against your product architecture, identify prior art that may bound the claims, and surface related Rich Media Club patent filings that could extend enforcement reach. For product and engineering teams building viewability measurement or guaranteed-view inventory systems, running this analysis before launch is significantly cheaper than defending an infringement action in the Arizona District Court.

What this case signals for the ad-tech viewability IP landscape
The Rich Media Club v. Duration Media dispute illustrates how viewability IP is being actively asserted against ad-exchange operators — and the litigation risks involved.
With-prejudice exits protect defendants but leave patents fully armed
Duration Media’s escape from this suit is defendant-specific. US11741482B2 remains valid and assertable. Competing ad-tech platforms operating similar viewability-as-a-service or guaranteed-viewable inventory products should treat this patent as an active enforcement risk, not a neutralised one.
Symmetric fee-bearing signals a negotiated exit, not a clear winner
When both parties absorb their own costs in a with-prejudice stipulation, it typically reflects a commercial resolution — possibly a license, a business arrangement, or mutual recognition of litigation risk. The absence of fee-shifting removes any adverse cost signal that would normally guide third parties on claim strength.
Rich v Duration — key questions answered
The case was dismissed with prejudice on 24 March 2025 pursuant to a stipulation by both parties. Judge Steven P. Logan entered the order granting the Stipulation of Dismissal (Doc. 62). Each party bears its own costs and attorneys’ fees. The with-prejudice designation means Rich Media Club cannot re-file the same infringement claims against Duration Media.
Rich Media Club asserted US11741482B2 (application number US17/961952), a US utility patent covering technology in the digital advertising viewability space. The accused products were Duration Media’s Highly Viewable Ad Exchange (HVAX) and its Viewability as a Service (VaaS) products and services.
A with-prejudice stipulated dismissal terminates the specific litigation permanently — Rich Media Club cannot re-assert US11741482B2 against Duration Media’s HVAX and VaaS products. However, the patent itself remains valid and enforceable. Rich Media Club retains the right to assert US11741482B2 against other parties in the market whose products may infringe.
The case was heard in the United States District Court for the District of Arizona, assigned to Judge Steven P. Logan. It was filed on 19 September 2023 and terminated on 24 March 2025, lasting 552 days. Rich Media Club was represented by Global IP Law Group LLC; Duration Media was represented by multiple Dentons US LLP offices.
Yes. The Rich Media Club v. Duration Media litigation demonstrates that US11741482B2 has been actively asserted against a commercial viewability platform operator. Although the case settled, no invalidity finding was made. Companies developing highly viewable ad exchanges, viewability measurement tools, or viewability-as-a-service products should conduct a freedom-to-operate analysis against this patent before launch or scaling.
