ServStor Technologies v. ZTE Corp.: Five Storage Patents, Dismissed With Prejudice After 398 Days
ServStor Technologies LLC filed suit in the Eastern District of Texas asserting five U.S. storage architecture patents against a broad lineup of ZTE server and cloud storage products. The parties jointly moved to dismiss with prejudice after 398 days — a resolution that permanently extinguishes all asserted claims.
Five Storage Patents, One Settlement: The ServStor–ZTE Resolution
On March 21, 2024, ServStor Technologies LLC filed a patent infringement action against ZTE Corporation in the Eastern District of Texas (Case No. 2:24-cv-00205), asserting five U.S. patents — US7310750B1, US7191274B1, US6738930B1, US7870271B2, and US7000010B1 — that cover storage architecture and data access technologies. The accused products spanned ZTE’s server and cloud storage portfolio, including the E5430 G4, R-series G5 appliances, and multiple ZXCLOUD platform variants.
The case closed on April 23, 2025, when the court granted a joint motion to dismiss all claims with prejudice. The ‘with prejudice’ designation is legally significant: ServStor cannot refile the same infringement claims against ZTE on the asserted patents. Each party was ordered to bear its own costs, attorneys’ fees, and expenses — a cost allocation consistent with a negotiated resolution rather than a contested adjudication on the merits.
The 398-day duration and the ‘with prejudice’ dismissal together suggest the parties likely reached a private agreement — possibly a license, covenant not to sue, or lump-sum settlement — before filing the joint motion. The public record does not disclose financial terms, any license grant, or the specific trigger for resolution. What remains unknown is whether ZTE secured a forward-looking license to the asserted storage patent portfolio or simply obtained a release of the disputed claims.

Dismissed with prejudice: what the joint motion means for both parties
Dismissal with prejudice bars any refiling on these patents
A dismissal with prejudice operates as a final adjudication on the merits for res judicata purposes. ServStor cannot refile infringement claims on the five asserted patents — US7310750B1, US7191274B1, US6738930B1, US7870271B2, and US7000010B1 — against ZTE in any U.S. federal court. The joint nature of the motion signals mutual agreement, distinguishing this from a unilateral concession.
Permanent bar on refilingServStor’s leverage ends here — but likely extracted value first
For ServStor, a with-prejudice dismissal forecloses any future enforcement of these five patents against ZTE specifically. The 398-day litigation period and joint motion structure are consistent with ServStor having secured undisclosed consideration — such as a license fee or settlement payment — before agreeing to permanent termination. The patents remain enforceable against third parties not party to this action.
Private value likely extractedZTE achieves permanent closure on all five asserted patents
ZTE obtains a permanent release from the five storage architecture patents asserted in this action, covering its E5430, R-series G5, and ZXCLOUD product families. The cost-bearing arrangement — each side paying its own fees — is typical of negotiated resolutions and avoids an exceptional-case fee award. ZTE likely required the with-prejudice designation as a condition of any commercial resolution, securing certainty for its storage product roadmap.
Product line cleared of these claimsServStor’s portfolio remains live against the broader storage market
The five asserted patents cover storage architecture and data access methods relevant across the server and cloud storage industry. A bilateral resolution with ZTE does not affect ServStor’s ability to assert the same portfolio against other manufacturers offering competing storage products. Competitors and OEMs in the enterprise storage and hyperconverged infrastructure space should treat this case as a signal that the portfolio is being actively monetised.

Official order — verbatim text
The court’s order adopts the joint motion verbatim, granting dismissal with prejudice across all claims and causes of action. The ‘WITH prejudice’ capitalisation in the order mirrors the parties’ own motion language, confirming that the res judicata bar was a mutually agreed condition — not a court-imposed sanction. The cost-bearing clause (‘each party to bear its own costs’) is neutral and provides no inference as to which party initiated the resolution or the relative strength of the underlying infringement and validity positions.
US7310750B1 — Storage architecture and data access control patent
The five asserted patents — US7310750B1, US7191274B1, US6738930B1, US7870271B2, and US7000010B1 — share a common technical domain in storage architecture, data access management, and related control methods for enterprise storage systems. Filed across application numbers ranging from US09/681078 to US11/243143, these patents span multiple generations of storage technology development. The portfolio’s breadth across filing dates suggests layered coverage of storage system architectures that remain relevant to contemporary server and cloud storage product designs.
For the enterprise storage and cloud infrastructure sector, a five-patent portfolio asserted against products like ZTE’s ZXCLOUD and R-series G5 platforms signals that the underlying inventions are considered applicable to modern hyperconverged and cloud-native storage architectures — not merely legacy hardware. Any manufacturer or OEM offering server storage, NAS, SAN, or HCI platforms with data access and caching functionality similar to the accused ZTE products should treat this portfolio as a live enforcement risk, particularly given the with-prejudice resolution that validates the portfolio’s licensing leverage.
Should you run an FTO analysis against US7310750B1 and the ServStor portfolio?
If your organisation designs, manufactures, or sells enterprise server storage, cloud storage appliances, or hyperconverged infrastructure products — especially those with data access management, caching, or storage controller architectures — the five patents asserted against ZTE are directly relevant to your freedom-to-operate position. The with-prejudice resolution confirms these patents have survived pre-litigation scrutiny sufficiently to compel a major vendor to settle. R&D and product teams launching new storage platforms should validate that their architectures do not read on these claims before go-to-market.
PatSnap Eureka’s FTO Search Agent can map your product’s technical features against the claim scope of all five asserted patents — US7310750B1, US7191274B1, US6738930B1, US7870271B2, and US7000010B1 — identifying claim elements that may overlap with your storage architecture. Eureka can also surface prior art relevant to invalidity, monitor ServStor’s portfolio for continuation filings, and flag new infringement actions by Fabricant LLP in E.D. Texas, giving your legal and product teams a continuous early-warning system.

What this case signals for the enterprise storage IP landscape
Five storage architecture patents, 11 accused products, and a with-prejudice exit: the ServStor enforcement campaign is a pattern worth tracking.
With-prejudice dismissals in E.D. Texas almost always signal a paid resolution
When both parties jointly seek dismissal with prejudice and bear their own costs, the public record strongly suggests undisclosed commercial terms. For competitors watching this case, the implication is that ServStor’s storage patent portfolio has demonstrated sufficient licensing leverage to compel ZTE — a major infrastructure vendor — to resolve rather than litigate to judgment.
The five-patent assertion strategy broadens claim coverage and settlement pressure
Asserting five patents simultaneously across multiple patent families — spanning different application numbers and grant dates — increases the technical surface area a defendant must address in claim construction and invalidity proceedings. This multi-patent approach is consistent with an NPE enforcement strategy designed to raise the cost and complexity of a full defence, accelerating settlement timelines.
ServStor v ZTE — key questions answered
ServStor Technologies LLC sued ZTE Corporation in the Eastern District of Texas asserting five storage architecture patents (US7310750B1, US7191274B1, US6738930B1, US7870271B2, US7000010B1) against ZTE’s server and ZXCLOUD product lines. The case was dismissed with prejudice by joint motion after 398 days, with each party bearing its own costs. No public financial terms were disclosed.
A with-prejudice dismissal permanently bars ServStor from refiling the same infringement claims under the five asserted patents against ZTE. It operates as a final adjudication on the merits for res judicata purposes. However, ServStor retains the right to enforce the same patents against other defendants not party to this action.
The accused products included the ZTE E5430 G4, ZTE R5200/R5300/R5500/R6500/R8500 G5 series, ZTE ZXCLOUD KS3200, ZXCLOUD KU5200, ZXCLOUD R5300 G4, ZXCLOUD R8500 G4, and ZXCLOUD KS10000 — spanning ZTE’s server appliance and cloud storage platform portfolio.
ServStor was represented by Fabricant LLP (including the New York office), Rubino IP, Rubino Law LLC, and Truelove Law Firm. ZTE was represented by Benesch, Friedlander, Coplan & Aronoff LLP and Findlay Craft PC. Key attorneys included Alfred Ross Fabricant and Vincent J. Rubino III for plaintiff, and Charles M. McMahon and Eric Hugh Findlay for defendant.
No. A bilateral with-prejudice dismissal resolves claims only between ServStor and ZTE. The five asserted patents remain valid and enforceable against any other party. The resolution actually signals that the portfolio has sufficient licensing leverage to compel settlement, potentially increasing the risk that ServStor or Fabricant LLP will pursue further actions against other enterprise storage and cloud infrastructure manufacturers.
