Content Aware LLC v. Nosto Solutions Ltd.: Dismissed With Prejudice After 152 Days
Content Aware, LLC filed suit in the Eastern District of Texas asserting US11107098B2 — a patent covering content recognition and data categorization — against Nosto Solutions Ltd., a personalisation technology provider. The plaintiff voluntarily dismissed the case with prejudice just 152 days after filing, with each party bearing its own costs.
A swift voluntary exit in a content-recognition patent dispute
On 3 November 2024, Content Aware, LLC filed a patent infringement action against Nosto Solutions Ltd. in the United States District Court for the Eastern District of Texas (Case No. 2:24-cv-00894). The sole asserted patent was US11107098B2, applied for under application number US16/838021, which covers a system and method for content recognition and data categorization. Nosto Solutions Ltd. is a provider of e-commerce personalisation technology, making it a commercially plausible target for a patent asserting broad content-recognition and data-categorization capabilities.
The case closed on 4 April 2025, just 152 days after filing, when plaintiff Content Aware, LLC filed a Notice of Voluntary Dismissal with prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(i). The court accepted and acknowledged the notice, formally dismissing all pending claims with prejudice and denying all remaining requests for relief as moot. Crucially, the dismissal is with prejudice, meaning Content Aware is permanently barred from reasserting the same claims against Nosto in any future action.
A resolution of 152 days — before any defendant appearance on the docket and without a cost award — typically suggests the parties reached a private accommodation, or that plaintiff reassessed the strength of its case early in proceedings. The public record does not disclose whether a settlement, licence, or strategic retreat drove the dismissal. The absence of defendant agents on record suggests Nosto may never have formally appeared, consistent with a very early resolution. The financial terms, if any, remain confidential.

Dismissed with prejudice: what the order means for both parties
Rule 41(a)(1)(A)(i): plaintiff’s right to exit — at a permanent cost
Under FRCP 41(a)(1)(A)(i), a plaintiff may voluntarily dismiss before the defendant files an answer or motion for summary judgment. Here, plaintiff elected dismissal with prejudice — a stronger concession than a without-prejudice exit. The court accepted the notice without a merits ruling, but the with-prejudice designation makes the dismissal functionally final: the same claims cannot be relitigated.
Voluntary dismissal — Rule 41(a)(1)(A)(i)With prejudice forecloses any future action on these claims
A dismissal with prejudice operates as an adjudication on the merits under res judicata principles. Content Aware cannot refile the same infringement claims based on US11107098B2 against Nosto Solutions in any federal court. This is a materially stronger outcome for Nosto than a without-prejudice dismissal, which would leave the door open for a refiled suit. The public record confirms the with-prejudice designation explicitly.
Permanent bar on re-litigationNosto exits without a merits ruling — but gains permanent protection
Nosto Solutions Ltd. secured a with-prejudice dismissal without apparently filing any responsive pleading, suggesting an early resolution before significant litigation expenditure. While Nosto did not obtain a formal declaration of non-infringement or invalidity, the with-prejudice dismissal provides durable protection against this specific plaintiff on this specific patent. No costs or fees were awarded, leaving each party’s litigation spend unrecovered.
No merits ruling; no fee awardEarly exit patterns in content-recognition assertions carry strategic signals
A rapid, with-prejudice voluntary dismissal before defendant appearance in E.D. Tex. is consistent with either a confidential licence/settlement or a plaintiff decision not to pursue the case further after defendant signalled a strong defence. For competitors in the content recognition and personalisation space, US11107098B2 remains a live, granted patent capable of being asserted against others. The Nosto dismissal offers no precedential claim-scope guidance.

Official order — verbatim text
The court’s order tracks the plaintiff’s notice language precisely, confirming dismissal with prejudice under Rule 41(a)(1)(A)(i) and directing the clerk to close the case. The with-prejudice designation is significant: it was elected by the plaintiff, not imposed by the court, suggesting a deliberate strategic decision. The denial of all pending relief as moot and the mutual cost-bearing instruction are standard for this procedural posture but leave no financial remedy for either party on the public record.
US11107098B2 — Content Recognition and Data Categorization System
US11107098B2, filed under application number US16/838021, protects a system and method for content recognition and data categorization. Patents in this class typically cover automated processes for identifying, classifying, and organizing digital content — capabilities foundational to modern personalisation engines, recommendation systems, and content delivery platforms. The patent is granted and remains in force, conferring exclusive rights over the claimed methods and systems.
In a market where e-commerce personalisation, behavioural data tagging, and automated content classification are standard features of competing platforms, a broadly drafted content-recognition patent poses meaningful infringement risk. Companies offering product recommendation engines, dynamic content targeting, or AI-driven data categorization — as Nosto Solutions does — sit squarely within the potential claim scope. The absence of any invalidity ruling in the Nosto case means the patent’s validity has not been tested in adversarial proceedings.
Should you run an FTO analysis against US11107098B2?
Any company operating in content recognition, automated data categorization, or e-commerce personalisation — including recommendation engines, content tagging platforms, and martech stacks — should evaluate exposure to US11107098B2. The patent survived this litigation without a validity challenge, and the plaintiff entity retains enforcement rights. If your product automatically classifies, categorizes, or acts on digital content at scale, a freedom-to-operate review is commercially prudent before Content Aware broadens its assertion campaign.

What this case signals for the content recognition IP landscape
A swift with-prejudice exit in E.D. Tex. raises questions about assertion strategy and the durability of content-recognition patents.
US11107098B2 remains enforceable — other targets should take notice
The dismissal of the Nosto case does not invalidate or limit US11107098B2. Content Aware, LLC retains the patent and may assert it against other companies operating in content recognition, data categorization, or e-commerce personalisation. Any company whose product reads on the patent’s claims should treat this case as an early warning signal, not a clearance event.
E.D. Tex. early dismissals often mask private licensing outcomes
When a patent assertion case in the Eastern District of Texas closes voluntarily with prejudice before defendant appearance — with each party bearing own costs — the most commercially common explanation is a private licence or settlement agreement. IP teams monitoring Content Aware’s assertion activity should track whether similar cases are filed against other personalisation or recommendation-engine vendors.
Content v Nosto — key questions answered
Content Aware, LLC asserted US11107098B2, filed under application number US16/838021, covering a system and method for content recognition and data categorization. This was the sole patent asserted in the Eastern District of Texas infringement action.
The plaintiff, Content Aware, LLC, voluntarily filed a Notice of Dismissal with prejudice under FRCP 41(a)(1)(A)(i). The court accepted the notice and formally dismissed all claims. The public record does not disclose the underlying reason, though early with-prejudice voluntary dismissals in E.D. Tex. frequently suggest a private settlement or licence agreement was reached.
No. A voluntary dismissal with prejudice extinguishes Content Aware’s claims against Nosto Solutions specifically, but does not affect the validity or enforceability of US11107098B2 against third parties. The patent remains granted and in force. No court made any finding regarding claim validity or infringement.
The court’s order directed each party to bear its own costs, expenses, and attorneys’ fees. This means neither side was awarded a cost or fee recovery — a standard outcome in voluntary dismissals without a merits ruling. It also means Nosto cannot recover its legal costs from Content Aware despite the case being dismissed.
No. A dismissal with prejudice operates as a final adjudication on the merits under res judicata doctrine. Content Aware is permanently barred from asserting the same patent claims covered by US11107098B2 against Nosto Solutions Ltd. in any future federal court action. However, Content Aware retains the right to assert the patent against other defendants.
