ServStor Technologies v. Inspur Group: Five-Patent Server & Storage Dispute Ends in Dismissal With Prejudice
ServStor Technologies LLC asserted five patents covering disk drive partitioning, server functionality, and industrial PC management against Chinese server manufacturer Inspur Group. Filed in the Eastern District of Texas in April 2023, the case closed after 501 days with a voluntary dismissal with prejudice — extinguishing all claims permanently.
Five-Patent E.D. Texas Server IP Case Ends Without Merits Ruling
ServStor Technologies LLC, a patent assertion entity holding a portfolio of legacy server and storage patents, filed suit against Inspur Group Co., Ltd. in the Eastern District of Texas on 21 April 2023. The complaint alleged infringement of five U.S. patents spanning disk drive partitioning methods, independent server functionality in a single PC, industrial PC environmental monitoring, and web-page caching on management appliances — technology domains squarely relevant to Inspur’s enterprise server product lines.
The case closed on 3 September 2024 via a court-ordered voluntary dismissal with prejudice, granted on the plaintiff’s own motion. Notably, the court simultaneously set aside an earlier entry of default against Inspur, suggesting the defendant had not formally appeared before the dismissal motion was filed. A dismissal with prejudice operates as a final adjudication on the merits for res judicata purposes, permanently barring ServStor from re-asserting these specific claims against Inspur.
The 501-day duration, combined with the absence of any defendant law firm on record and the prior entry of default, suggests the parties may have reached a private resolution — or that ServStor elected to walk away — without a contested merits hearing. The public record is silent on any settlement terms, financial consideration, or licensing agreement. What drove the decision to dismiss rather than pursue the default judgment remains unknown from available filings.

Dismissed with prejudice: what the voluntary dismissal means for both parties
Voluntary dismissal with prejudice is a permanent, self-inflicted bar
Under Federal Rule of Civil Procedure 41(a), a dismissal with prejudice operates as a final adjudication on the merits. ServStor cannot re-file these same patent claims against Inspur in any U.S. federal court. The court also set aside the prior entry of default, meaning no default judgment was preserved. The practical effect is that all five asserted patents are exhausted against this defendant.
Rule 41(a) — permanent barThe ‘with prejudice’ designation matters enormously here
A voluntary dismissal without prejudice would have allowed ServStor to re-file the same claims later. A dismissal with prejudice does not. The court’s order explicitly confirms the ‘with prejudice’ designation, meaning ServStor affirmatively surrendered its litigation rights against Inspur on all five patents. This distinction is critical for any third party assessing whether these patents remain an active enforcement risk against other defendants.
Re-filing barred against InspurInspur exits without a merits ruling — but default history is unusual
Inspur Group faces no adverse judgment and no injunction. The simultaneous setting aside of the default entry means the defendant’s record is clean. However, the fact that a default was entered at all — suggesting Inspur did not timely respond — is noteworthy for a company of its scale. Whether a confidential settlement drove the dismissal, or whether ServStor simply lacked the resources to pursue the case, is not determinable from the public record.
No liability foundFive legacy patents remain enforceable against other server makers
The dismissal with prejudice only bars claims against Inspur. ServStor’s five patents — covering disk partitioning, server independence, IPC monitoring, and web caching on management appliances — remain issued and potentially enforceable against other defendants. Companies manufacturing or distributing products in these categories should assess whether these patents present a continued assertion risk, particularly given ServStor’s demonstrated willingness to file in the plaintiff-friendly Eastern District of Texas.

Official order — verbatim text
The court’s order grants the plaintiff’s own motion and does not adjudicate infringement, validity, or damages on the merits. The ‘with prejudice’ designation is the operative legal consequence: it forecloses any future U.S. federal court action by ServStor against Inspur on these five patents. The simultaneous vacation of the default entry is procedurally significant — it ensures Inspur carries no adverse default judgment on its record, suggesting the resolution was coordinated rather than unilateral.
US7310750B1 — Disk Drive Partitioning Methods and Apparatus
US7310750B1 (App. No. 10/707748) is the lead patent asserted, covering disk drive partitioning methods and apparatus — a foundational layer of enterprise storage architecture. The remaining four patents (US7191274B1, US6738930B1, US7870271B2, US7000010B1) address industrial PC environmental monitoring, independent server functionality within a single PC chassis, and web-page caching on management appliances. Application filing dates trace to the early 2000s, placing the inventions in the era of early enterprise server consolidation and blade architecture development.
This portfolio targets infrastructure-level functionality embedded in enterprise and industrial server platforms — technology that Inspur, as a major OEM, would implement across broad product lines. The commercial significance lies in the breadth of the claims: disk partitioning and server independence features appear in virtually all modern enterprise servers, making these patents potentially high-coverage assets. For competitors and system integrators active in the U.S. market, the persistence of these patents in an active assertion entity’s portfolio represents a non-trivial clearance risk.
Should you run an FTO against US7310750B1 and the ServStor storage patent portfolio?
Any company manufacturing, importing, or distributing enterprise servers, storage arrays, industrial PCs, or server management appliances in the U.S. market should treat this portfolio as a live FTO priority. The dismissal with prejudice covers only Inspur — every other potential defendant remains exposed. Given the E.D. Texas filing history and the PAE enforcement model, a targeted clearance analysis against all five patents is commercially prudent before product launch or market entry.
PatSnap Eureka’s FTO Search Agent can map each of the five asserted claims against your product specifications, flag relevant prior art, and identify claim scope limitations that may narrow exposure. Eureka also tracks the prosecution history and any inter partes review filings against these patents, giving your legal and R&D teams a real-time enforcement risk dashboard specific to the ServStor portfolio.

What this case signals for the enterprise server and storage IP landscape
A five-patent assertion with a default entry that ends in voluntary dismissal with prejudice raises key questions for server IP strategy.
Legacy storage and server patents remain viable assertion vehicles in E.D. Texas
ServStor’s portfolio covers technology dating to early 2000s application filings, yet was asserted in 2023 against a major enterprise server OEM. This pattern — older infrastructure patents asserted against current products — is common in E.D. Texas and warrants ongoing FTO monitoring for any company in the server, storage, or industrial PC management space.
Default entries against foreign defendants signal a due-process pressure point
Inspur’s failure to timely respond — resulting in a default entry — is a pattern seen with foreign defendants served under the Hague Convention. Companies with limited U.S. litigation infrastructure should treat E.D. Texas filings as requiring immediate domestic counsel engagement, regardless of perceived case merit, to avoid default exposure.
ServStor v Inspur — key questions answered
ServStor Technologies LLC filed a patent infringement action against Inspur Group Co., Ltd. in the Eastern District of Texas in April 2023, asserting five patents covering disk partitioning, server functionality, and industrial PC management. The case was voluntarily dismissed with prejudice on 3 September 2024 after 501 days, with the court simultaneously setting aside an earlier entry of default against Inspur.
A dismissal with prejudice permanently bars ServStor from re-filing these specific infringement claims against Inspur Group in any U.S. federal court. However, the five patents — US7310750B1, US7191274B1, US6738930B1, US7870271B2, and US7000010B1 — remain issued and potentially enforceable against other defendants. The dismissal extinguishes rights only as against Inspur.
The public record indicates a default was entered against Inspur (Dkt. No. 10), suggesting the defendant failed to timely respond to the complaint. This is a pattern sometimes seen with foreign defendants where service under the Hague Convention causes delays. The default was set aside simultaneously with the voluntary dismissal, leaving no adverse default judgment on record.
The public record does not confirm a settlement. However, the combination of a plaintiff-initiated motion to set aside the default entry and simultaneously dismiss with prejudice is commercially consistent with a private resolution. A simple abandonment of claims would not typically require setting aside the default. The record is silent on any financial consideration or licensing terms.
The case record references products covering disk drive partitioning methods and apparatus, environmental monitoring for industrial PCs, independent server functionality within a single PC, and web-page caching on management appliances — technology domains associated with Inspur’s enterprise server and storage product lines. Specific Inspur model numbers are not identified in the available public record.
