ServStor Technologies v. Hewlett-Packard — Dismissed With Prejudice After 305 Days
ServStor Technologies, LLC asserted five server-storage patents against Hewlett-Packard’s broad HPE product line — including ProLiant, Alletra, Nimble Storage, and Apollo systems — in the Eastern District of Texas. After 305 days, ServStor voluntarily dismissed all claims with prejudice, permanently closing the litigation door on these assertions.
Five-patent server storage assertion ends in permanent self-dismissal
ServStor Technologies, LLC filed suit against Hewlett-Packard, Co. on 21 April 2023 in the Eastern District of Texas (Case No. 2:23-cv-00182), asserting infringement of five US patents — US7310750B1, US7191274B1, US6738930B1, US7870271B2, and US7000010B1 — covering server storage architecture and interconnect technologies. The accused products spanned virtually the entire HPE server and storage portfolio, including ProLiant, Alletra, Apollo, Nimble Storage, SimpliVity, Synergy, Superdome Flex, Integrity, Converged System, and GreenLake Edge-to-Cloud Platform.
On 20 February 2024 — 305 days after filing — ServStor filed a Notice of Voluntary Dismissal with Prejudice under Rule 41(a)(1)(A)(i). The court accepted and acknowledged the notice, formally dismissing all pending claims and denying all remaining relief requests as moot. Dismissal with prejudice is the most conclusive form of voluntary exit: it functions as a judgment on the merits, barring ServStor from reasserting the same five patents against HP in any future action.
The relatively swift resolution — less than eleven months into what could have been multi-year litigation — suggests the parties may have reached an undisclosed resolution, or that ServStor elected to withdraw after assessing the strength of HP’s defence, which was mounted by a large DLA Piper team across multiple US offices. No financial terms or licensing details are reflected in the public record. The choice of prejudicial dismissal, rather than without-prejudice withdrawal, is a meaningful concession that warrants attention from other patent holders in the server storage space.

Days from filing to voluntary dismissal with prejudice
Voluntary dismissal with prejudice — what it means for both parties
Rule 41(a)(1)(A)(i) — plaintiff’s unilateral exit before answer or summary judgment
ServStor invoked Federal Rule of Civil Procedure 41(a)(1)(A)(i), which permits a plaintiff to dismiss without a court order before the defendant serves an answer or a motion for summary judgment. The notable element here is that ServStor chose to make the dismissal with prejudice — a voluntary and permanent relinquishment of all asserted claims — rather than taking a without-prejudice exit that would preserve future filing rights.
FRCP 41(a)(1)(A)(i)With prejudice bars any future assertion of these five patents against HP
A with-prejudice dismissal carries res judicata effect: ServStor is permanently barred from reasserting US7310750B1, US7191274B1, US6738930B1, US7870271B2, and US7000010B1 against Hewlett-Packard on these same grounds. This is a materially stronger outcome for HP than a without-prejudice dismissal, which would merely have paused the dispute. For ServStor, the decision to accept prejudice typically signals either a settlement providing sufficient commercial value, or a strategic reassessment of claim viability.
Permanent bar on re-assertionDLA Piper’s six-attorney team likely signalled a costly, contested defence
HP retained DLA Piper across three US offices (Palo Alto, San Diego, and Texas) plus local counsel Haltom & Doan, assembling a six-named-attorney defence team. For a patent assertion entity like ServStor, facing that depth of resource — particularly DLA Piper’s established patent litigation bench — typically raises the cost-benefit calculus of continued prosecution. This resourcing signal is consistent with HP preparing a vigorous invalidity and non-infringement defence.
Heavy enterprise defence deploymentEDTX filing — a familiar jurisdiction for patent assertion activity
The Eastern District of Texas remains a popular venue for patent plaintiffs due to its established patent litigation procedures and historically plaintiff-friendly docket management. ServStor’s choice of EDTX for a five-patent assertion against a global defendant is consistent with common assertion-entity strategy. The early dismissal before substantive Markman proceedings suggests HP’s defence posture may have neutralised the jurisdictional advantage ServStor sought.

Stipulation of dismissal — official text
The court’s order accepts ServStor’s Rule 41(a)(1)(A)(i) notice without requiring HP’s consent, as is procedurally standard at this stage. The phrase ‘dismissed with prejudice’ is unambiguous: the court treats it as a final adjudication barring refiling. The denial of all pending relief ‘as moot’ confirms no substantive motions were resolved on the merits. HP receives a clean exit with no outstanding claims — a strong procedural outcome, though the absence of a cost award means HP bears its own defence expenses.
US7310750B1 and four further patents — server storage architecture portfolio
The five patents asserted in this case — US7310750B1, US7191274B1, US6738930B1, US7870271B2, and US7000010B1 — cover various aspects of server storage architecture, interconnect management, and data access control. Their application numbers suggest priority dates in the 2000–2005 window, coinciding with the early evolution of enterprise SAN/NAS architectures and server-attached storage systems. This technical domain underpins a wide range of modern HPE products, from ProLiant rack servers to Nimble flash arrays and hyperconverged SimpliVity platforms.
The breadth of accused products in this case — sixteen distinct HPE product lines including GreenLake cloud services — suggests ServStor interpreted its patent claims broadly across both on-premise and edge-to-cloud infrastructure. For server and storage vendors, this type of portfolio poses particular risk because foundational storage interconnect claims can potentially read across multiple product generations. The age of these patents also means invalidity arguments based on prior art from the early 2000s enterprise storage space would have been a natural defence pillar for HP.
Should your team run an FTO against US7310750B1 and the ServStor storage portfolio?
Any company selling enterprise servers, flash storage arrays, hyperconverged infrastructure, or cloud-edge platforms in the US market should assess exposure to this five-patent portfolio. The accused product list in this case — spanning rack servers, all-flash arrays, converged systems, and as-a-service platforms — indicates ServStor’s claims were drafted or interpreted to reach broadly across the modern data centre stack. If your products operate in any of these categories, an FTO review of US7310750B1, US7191274B1, US6738930B1, US7870271B2, and US7000010B1 is warranted before the patents expire.
PatSnap Eureka’s FTO Search Agent can map each of the five patent claims against your product specifications, flag relevant prior art that could support invalidity arguments, and monitor for continuation applications filing from the same priority families. Given the 2000–2005 priority window, expiry timing for each patent should be confirmed — but continuation risk from these families should not be assumed to be closed without a thorough family-level search.

What this case signals for the server storage IP landscape
A five-patent assertion against HP’s full server portfolio, ending in permanent self-dismissal — here is what IP teams need to take away.
The with-prejudice exit protects HP but confirms the patents remain live against others
The dismissal only bars ServStor from suing HP on these five patents. US7310750B1, US7191274B1, US6738930B1, US7870271B2, and US7000010B1 remain in force and could be asserted against other server or storage vendors. Competitors to HP operating in the HPE product categories named in this suit — ProLiant-class servers, NVMe/flash storage arrays, hyperconverged infrastructure — should assess their own exposure to this portfolio.
Early voluntary exits often signal undisclosed licensing activity
When a plaintiff dismisses with prejudice before claim construction, it is statistically consistent with a confidential licence or settlement that makes continued litigation unnecessary. The public record is silent on financial terms. IP counsel tracking ServStor’s licensing strategy should note that a with-prejudice exit voluntarily accepted — rather than obtained by court order — typically reflects a negotiated commercial resolution rather than a unilateral concession of weakness.
ServStor v Hewlett-Parkard — key questions answered
ServStor Technologies filed a patent infringement suit against Hewlett-Packard in the Eastern District of Texas on 21 April 2023, asserting five server storage patents. On 20 February 2024, ServStor voluntarily dismissed the case with prejudice under FRCP 41(a)(1)(A)(i), permanently barring any refiling of the same claims against HP. The case lasted 305 days.
ServStor asserted US7310750B1, US7191274B1, US6738930B1, US7870271B2, and US7000010B1. These five patents cover server storage architecture and interconnect technologies, with application priority dates believed to fall in the 2000–2005 timeframe based on their application numbers.
The accused products included HPE ProLiant servers (including DL320 Gen11), HPE Alletra servers, HPE Apollo 2000 Gen10 Plus systems, HPE Nimble Storage Adaptive Flash and All Flash Arrays, HPE SimpliVity, HPE Synergy, HPE Superdome Flex, HPE Integrity, HPE Converged System servers, HPE GreenLake Edge-to-Cloud Platform, and stack hubs — sixteen product categories in total.
A with-prejudice dismissal carries the effect of a final judgment on the merits. It permanently bars ServStor from reasserting the same five patents against Hewlett-Packard in any future action. This is a stronger outcome for HP than a without-prejudice dismissal, which would have left ServStor free to refile. The court accepted ServStor’s notice and denied all remaining relief as moot.
The public record does not disclose the reason for the with-prejudice dismissal. Possible explanations include a confidential licensing agreement or settlement making further litigation unnecessary, or a strategic decision by ServStor that continuing against HP’s large DLA Piper defence team was not commercially viable. The choice of prejudicial rather than without-prejudice dismissal is notable and suggests a deliberate commercial resolution rather than a simple withdrawal.
