SITO Mobile v. Hulu: Seven-Patent Media Routing Dispute Dismissed With Prejudice
SITO Mobile R&D IP and SITO Mobile, Ltd. brought a patent infringement action against streaming giant Hulu, LLC asserting seven patents covering systems and methods for routing media. After 1,005 days of litigation in the California Central District Court, both parties jointly moved to dismiss all claims and counterclaims with prejudice, each bearing its own costs.
Seven media-routing patents, one streaming platform, 1,005 days — then silence
On 5 August 2021, SITO Mobile R&D IP, LLC and SITO Mobile, Ltd. filed suit against Hulu, LLC in the United States District Court for the Central District of California, asserting infringement of seven patents — US8825887B2, US9135636B2, US9026673B2, US9135635B2, US10009637B2, US9591360B2, and US10171846B2 — all directed to systems and methods for routing media. The asserted portfolio spans application dates across two distinct filing clusters, suggesting a deliberate multi-generational patent strategy targeting the streaming and targeted-content delivery space.
The case closed on 6 May 2024 via a joint motion to dismiss all claims and counterclaims with prejudice under Fed. R. Civ. P. 41(a)(2). The court granted the motion, finding sufficient good cause. Dismissal with prejudice is legally significant: SITO Mobile cannot reassert any of the seven patents against Hulu on the same grounds. Hulu’s counterclaims — likely invalidity and non-infringement defences — were likewise extinguished. Each party was ordered to bear its own attorneys’ fees, costs, and expenses, suggesting a negotiated resolution without a clear financial victor on the record.
At 1,005 days, the case ran considerably longer than many patent disputes that settle before substantial motion practice, which may indicate the parties engaged in meaningful claim construction, discovery, or inter partes review proceedings before reaching terms. The mutual fee-bearing arrangement and simultaneous dismissal of all counterclaims is consistent with a confidential settlement, though the public record is silent on any financial or licensing terms. Whether SITO Mobile secured a licensing arrangement or Hulu obtained freedom-to-operate assurances cannot be confirmed from the docket alone.

Dismissed with prejudice: what the joint motion means for both parties
Rule 41(a)(2) dismissal with prejudice — a permanent close
Under Fed. R. Civ. P. 41(a)(2), a court may dismiss an action on terms it considers proper. Here, both parties jointly moved, and the court found good cause. ‘With prejudice’ is the critical qualifier: the dismissal operates as a final judgment on the merits, permanently barring SITO Mobile from re-filing the same patent claims against Hulu. This is distinct from a dismissal without prejudice, which would preserve the right to refile.
Permanent bar on re-filingSITO Mobile forfeits right to re-assert these patents against Hulu
By agreeing to dismiss with prejudice, SITO Mobile permanently surrendered its ability to pursue Hulu on these seven patents for the conduct at issue. However, the patents themselves remain in force against third parties. The mutual cost-bearing arrangement and the absence of a public adverse judgment on validity preserves SITO’s ability to assert the portfolio against other defendants in the streaming sector.
Patents survive; Hulu claim endsHulu obtains permanent resolution — but no invalidity ruling on record
Hulu achieves certainty: SITO Mobile cannot revive these specific claims. Crucially, Hulu’s counterclaims — almost certainly seeking invalidity or non-infringement declarations — were also dismissed. This means no court has adjudicated the validity of the seven patents on the merits. Hulu likely negotiated a licence or covenant not to sue as part of any confidential settlement, though this is not confirmed in the public record.
No validity ruling; claims endedSeven media-routing patents remain enforceable against the broader streaming market
Because no court invalidated any of the seven asserted patents, SITO Mobile’s portfolio retains its enforcement value against other streaming platforms and content delivery providers. Competitors operating similar media routing or targeted-content delivery systems should treat these patents as live threats. The 1,005-day duration and multi-patent scope suggest SITO Mobile is a sophisticated patent enforcement entity with the appetite and resources for prolonged litigation.

Official order — verbatim text
The court’s order granting the joint motion is deliberately concise — it confirms good cause and executes the parties’ agreed terms without making any findings on infringement, validity, or claim construction. The phrase ‘all claims and counterclaims are dismissed with prejudice’ is legally exhaustive: it eliminates every asserted theory from both sides simultaneously. The mutual cost-bearing clause is commercially significant, as fee-shifting under 35 U.S.C. § 285 was not sought or awarded, consistent with a negotiated exit rather than a litigation-determined outcome.
US8825887B2 — System and method for routing media (lead patent)
The seven asserted patents — led by US8825887B2 and spanning application numbers in the US13/8xxxxx and US15/6xxxxx series — cover systems and methods for routing media, a technology area central to streaming platforms’ ability to deliver targeted content, dynamic ad insertion, and personalised viewing experiences. The earliest application numbers suggest priority dates in the 2013–2016 range, positioning this portfolio to cover media routing architectures that underpinned the early growth of subscription and ad-supported streaming services.
For a platform the scale of Hulu — operating both subscription-video-on-demand and a live TV tier with programmatic advertising — systems for routing media to specific users based on behavioural or demographic signals sit at the commercial core of the business. A portfolio of seven patents in this domain, asserted simultaneously, creates compound infringement risk that is difficult to design around without touching multiple independent claims across the family. This enforcement posture is characteristic of licensing entities that have aggregated IP from original innovators in the mobile and connected-TV advertising space, where SITO Mobile has historical roots.
Should your team run an FTO against SITO Mobile’s media routing patent portfolio?
Any company operating a streaming platform, connected-TV application, AVOD service, or programmatic ad-insertion system should treat SITO Mobile’s seven-patent media routing portfolio as a live FTO priority. The Hulu dismissal with prejudice resolved claims only as between those two parties — the patents remain valid and enforceable against all other market participants. If your product involves routing media content to users based on profile data, device signals, or behavioural targeting, you are operating squarely in the technology space these patents address.
PatSnap Eureka’s FTO Search Agent enables R&D and IP teams to map product architectures against each of the seven asserted patents simultaneously, identifying independent claims that may read on streaming, ad-routing, or content delivery implementations. Eureka’s continuation-monitoring alerts can also flag new SITO Mobile filings in this family before grant, giving your team advance notice of expanding claim scope. Run your FTO analysis before a demand letter arrives — not after.

What this case signals for the streaming and media delivery IP landscape
A seven-patent enforcement action against Hulu lasting nearly three years carries clear signals for IP strategy in the streaming sector.
Multi-patent media routing portfolios are active enforcement tools
SITO Mobile’s seven-patent assertion across two filing clusters demonstrates that IP licensing entities are building and deploying layered patent portfolios specifically targeting streaming and media routing infrastructure. Streaming platforms with proprietary content delivery or ad-insertion architectures should audit exposure across generational patent families, not just individual patents.
Mutual fee-bearing dismissals typically signal confidential settlement
When both parties dismiss with prejudice and each bears its own costs after nearly three years of litigation, the pattern is strongly consistent with a confidential licensing or settlement agreement. For defendants in similar positions, this suggests that SITO Mobile is willing to resolve claims commercially — but only after substantial litigation investment has been made.
SITO v Hulu — key questions answered
SITO Mobile asserted seven patents: US8825887B2, US9135636B2, US9026673B2, US9135635B2, US10009637B2, US9591360B2, and US10171846B2. All seven cover systems and methods for routing media and were filed across two application number clusters, suggesting a multi-generational portfolio strategy targeting streaming and media delivery platforms.
Dismissal with prejudice under Fed. R. Civ. P. 41(a)(2) permanently bars SITO Mobile from re-asserting the same seven patents against Hulu for the same conduct. It operates as a final judgment on the merits. Hulu’s counterclaims were also dismissed with prejudice. No court ruled on validity or infringement, and the seven patents remain enforceable against other parties.
The public record shows only a joint motion to dismiss with prejudice, with each party bearing its own attorneys’ fees and costs. This pattern — mutual dismissal after nearly three years of litigation without a trial or adverse ruling — is strongly consistent with a confidential settlement or licensing agreement, but no settlement terms have been disclosed in the public docket.
Yes. Because the case was dismissed by joint motion before any court adjudicated validity or infringement, all seven patents — US8825887B2, US9135636B2, US9026673B2, US9135635B2, US10009637B2, US9591360B2, and US10171846B2 — retain their presumption of validity under 35 U.S.C. § 282 and remain enforceable against third parties in the streaming and media routing sector.
The case lasted 1,005 days — approximately 2.8 years — from filing on 5 August 2021 to closure on 6 May 2024. This duration is above average for multi-patent district court cases that resolve without trial, suggesting the parties engaged in substantial litigation activity such as claim construction briefing, discovery, or parallel USPTO proceedings before reaching their agreed resolution.
