DAZN v. Distributed Media Solutions: Four Streaming Patents, Dismissed With Prejudice
DAZN Limited brought a four-patent infringement action against Distributed Media Solutions in Delaware, asserting patents covering streaming data, rich media optimisation, and digital content distribution. The case closed with prejudice in under nine months — a resolution that permanently bars re-filing on the same claims.
A swift, permanent exit: DAZN drops four streaming patents in Delaware
On 27 September 2023, DAZN Limited — the global sports streaming platform — filed a patent infringement action in the District of Delaware (Case No. 1:23-cv-01061) against Distributed Media Solutions, LLC. The complaint asserted four US patents: US8122004B2, US6697811B2, US7739714B2, and US7133922B1, covering technologies including rich media presentation optimised for networked devices, streaming data delivery, information management and distribution, and digital data transmission over bandwidth-limited links.
The case was terminated on 29 May 2024 when DAZN filed a notice of voluntary dismissal, which Judge John F. Murphy converted into a formal order of dismissal with prejudice under Federal Rule of Civil Procedure 41(a)(1)(A). A dismissal with prejudice is the most final form of voluntary exit: DAZN is permanently barred from re-asserting these four patents against Distributed Media Solutions on the same operative facts. No defendant law firm or agent appeared on the public docket before closure, suggesting the case resolved before substantive litigation commenced.
At 245 days, the case closed before any claim construction or substantive ruling was issued. The absence of a defendant appearance and the with-prejudice nature of the dismissal is consistent with a confidential settlement — though the public record is silent on any financial terms. What drove DAZN to elect a permanent dismissal rather than a without-prejudice exit remains unknown from available filings, but the resolution eliminates future litigation risk for Distributed Media Solutions on all four asserted patents.

Dismissed with prejudice: what the Rule 41 order means for both parties
Rule 41(a)(1)(A) dismissal with prejudice explained
Under FRCP 41(a)(1)(A), a plaintiff may voluntarily dismiss an action before the defendant serves an answer or motion for summary judgment. When the court orders this dismissal ‘with prejudice,’ it carries the same res judicata effect as a final judgment on the merits. DAZN cannot re-file this action against Distributed Media Solutions on the same claims. The order was entered on the plaintiff’s own notice — no defendant consent was required at this procedural stage.
Permanent bar on re-filingDAZN permanently relinquishes these claims against this defendant
By accepting a with-prejudice dismissal, DAZN forfeited any future right to sue Distributed Media Solutions on the four asserted patents for the same accused conduct. This is a meaningful concession — a without-prejudice exit would have preserved optionality. The choice of with-prejudice typically suggests either a negotiated resolution (likely with compensation or licensing terms) or a strategic decision to close exposure from a potential fee award. The public record does not confirm which.
Claims extinguished against this defendantDistributed Media Solutions secures permanent freedom from these four patents
The with-prejudice dismissal delivers Distributed Media Solutions a durable outcome: DAZN’s four streaming patents — US8122004B2, US6697811B2, US7739714B2, and US7133922B1 — cannot be re-asserted against it on the same operative facts. No defendant counsel appeared on record before closure, suggesting the matter resolved without protracted litigation cost. The defendant’s freedom-to-operate position with respect to DAZN’s portfolio is now substantially de-risked.
Full defence on these patentsStreaming IP enforcement: the cost-benefit calculus at play
Cases resolved pre-answer with prejudice often reflect confidential licensing or settlement activity. For the streaming media sector, this pattern — asserting broad platform patents and resolving swiftly — is consistent with monetisation strategies targeting mid-market operators. The four patents span foundational streaming infrastructure: bandwidth-limited transmission, rich media optimisation, and content distribution. Competitors operating in these spaces should note the patents remain active and enforceable against other parties.

Official order — verbatim text
The order’s language — ‘DISMISSED WITH PREJUDICE under Federal Rule of Civil Procedure 41(a)(1)(A)’ — confirms this was a plaintiff-initiated exit carrying full res judicata effect. The reference to DI 14 as a ‘notice’ (not a stipulation) confirms no defendant consent was required, consistent with dismissal before any responsive pleading. The with-prejudice designation is the operative and consequential element: it transforms what is procedurally a voluntary act into a permanent adjudication on the right to bring these claims. No merits ruling was issued, and no claim construction record exists from this proceeding.
US8122004B2 — Rich media presentation optimised for networked devices
The four patents asserted in this case span the foundational infrastructure of modern streaming media delivery. US8122004B2 (App. No. 12/605830) covers generating and providing rich media presentations optimised per device over a network — directly relevant to adaptive streaming pipelines. US6697811B2 (App. No. 10/096116) claims methods and apparatus for data streaming. US7739714B2 (App. No. 10/330581) addresses information management and distribution systems, and US7133922B1 (App. No. 09/634947) covers digital data transmission over bandwidth-constrained links in plural blocks — a technique foundational to chunked or segmented delivery protocols.
Collectively, this portfolio targets the architecture that underpins OTT video delivery, CDN operations, and adaptive bitrate streaming — sectors that have expanded dramatically since these patents’ application dates. Their continued enforceability against market participants beyond this case makes them strategically significant. Any company operating a streaming platform, delivering video-on-demand, or building media distribution middleware in the US should assess exposure to this cluster of patents, particularly given DAZN’s demonstrated willingness to litigate in Delaware federal court.
Should you run an FTO analysis against US8122004B2 and related DAZN patents?
Any product team building or operating a streaming video platform, adaptive media player, CDN-integrated delivery system, or bandwidth-aware content distribution service in the US should treat this patent cluster as a live FTO concern. The dismissal with prejudice protects only Distributed Media Solutions — it creates no safe harbour for other operators. The patents cover device-optimised media presentation, streaming apparatus, information distribution systems, and limited-bandwidth data transmission: claims that map readily onto modern OTT and live sports streaming architectures.
PatSnap Eureka’s FTO Search Agent can run targeted claim mapping across all four patent numbers — US8122004B2, US6697811B2, US7739714B2, and US7133922B1 — against your product architecture in minutes. Eureka surfaces blocking claims, identifies prior art that may support invalidity arguments, and flags related continuations or divisionals that could extend the risk horizon. For streaming infrastructure teams, a documented FTO review also strengthens the case for design-around investment and informs licensing negotiation positions.

What this case signals for the streaming media IP landscape
A pre-answer dismissal with prejudice over four foundational streaming patents raises pointed questions about enforcement strategy and licensing leverage in the sector.
With-prejudice exit strongly suggests a negotiated resolution
Voluntary dismissals with prejudice at this early stage — before any defendant appearance — are rarely altruistic. The structure is consistent with a confidential licence or lump-sum settlement. IP teams monitoring DAZN’s enforcement posture should treat this as a live licensing programme, not a one-off filing. The four patents cover core streaming infrastructure and remain fully enforceable against third parties.
Delaware remains the venue of choice for streaming patent actions
DAZN chose Delaware even for what became a sub-nine-month case. This reflects the court’s predictable procedures and plaintiff-friendly venue rules for patent holders incorporated or registered there. R&D and product teams building streaming delivery systems should maintain FTO coverage for Delaware-filed assertions as a baseline operational standard, particularly for patents covering data transmission optimisation and adaptive media delivery.
Limited v Distributed — key questions answered
The court’s 29 May 2024 order dismissed the case with prejudice under FRCP 41(a)(1)(A), meaning DAZN cannot re-file against Distributed Media Solutions on the same four patents and operative facts. The dismissal carries the res judicata effect of a final judgment, permanently extinguishing DAZN’s claims against this specific defendant. The four patents remain enforceable against other parties.
DAZN asserted four patents: US8122004B2 (rich media presentation optimised for networked devices), US6697811B2 (streaming data method and apparatus), US7739714B2 (information management and distribution system), and US7133922B1 (digital data transmission over bandwidth-limited links). All four remain active and enforceable against third parties following the dismissal.
The public record does not confirm a settlement. However, the combination of a with-prejudice voluntary dismissal before any defendant appearance — and the absence of any fee motion — is broadly consistent with a confidential licensing or settlement agreement. A without-prejudice exit would have been available if DAZN simply chose to abandon the claims without compensation.
No. The with-prejudice dismissal binds only Distributed Media Solutions. US8122004B2, US6697811B2, US7739714B2, and US7133922B1 remain fully enforceable against any other party. Companies operating streaming platforms, CDN infrastructure, or adaptive media delivery systems in the US should not treat this dismissal as a safe harbour and should conduct independent FTO analysis.
Delaware is a frequently chosen venue for patent infringement actions due to its experienced patent judiciary, well-developed procedural norms, and favourable incorporation rules. DAZN’s choice of Delaware for a multi-patent streaming case is consistent with broader plaintiff strategies in the technology sector. The case was assigned to Judge John F. Murphy and closed before substantive proceedings commenced.
