xMatrix LLC v. Synology Inc. — Dismissed With Prejudice After 276 Days
xMatrix LLC filed a patent infringement action against Synology Inc. in the Eastern District of Texas, asserting two patents covering managed file backup via multi-services gateway and network premises gateway support infrastructure. The case resolved in 276 days and was dismissed with prejudice, with each party bearing its own costs.
Voluntary settlement ends xMatrix’s two-patent gateway infringement suit
On January 26, 2025, xMatrix LLC filed suit against Synology Inc. in the Eastern District of Texas (Case No. 2:25-cv-00077), asserting infringement of US8180735B2, directed to managed file backup and restore at remote storage locations through a multi-services gateway at user premises, and US10630501B2, directed to a system and method for providing network support services and premises gateway support infrastructure. Synology is a well-known provider of network-attached storage and data management appliances.
The case was resolved and dismissed with prejudice on October 29, 2025, following the parties’ joint Notice of Voluntary Dismissal. The court accepted the notice and dismissed all claims and causes of action with prejudice. Dismissal with prejudice is a final adjudication on the merits: xMatrix is permanently barred from re-asserting the same claims against Synology based on these patents in any future action. Each party was ordered to bear its own litigation costs.
Resolution in 276 days — before claim construction or any substantive merits ruling — suggests the parties likely reached a private settlement, though the public record does not disclose financial terms or licensing arrangements. The ‘with prejudice’ designation, combined with the mutual cost-bearing order, is consistent with a negotiated exit rather than a capitulation by either side. The absence of defendant law firm filings in the public record may reflect a late-stage settlement following early engagement between counsel.

Dismissed with prejudice: what the final order means for both parties
With-prejudice dismissal is a permanent bar on these claims
A voluntary dismissal with prejudice under Federal Rule of Civil Procedure 41(a) operates as a final adjudication on the merits. Unlike a without-prejudice dismissal — which preserves the right to re-file — a with-prejudice order permanently extinguishes xMatrix’s ability to assert the same patent claims against Synology in any subsequent action. The court’s acceptance of the notice converted the parties’ agreement into a binding judicial order.
Rule 41(a) — permanent dismissalPublic record is silent on financial terms or licence
The dismissal notice states only that ‘the above-captioned case has been resolved,’ without disclosing whether a licence, lump-sum payment, or covenant not to sue was exchanged. With-prejudice voluntary dismissals in patent cases frequently reflect private settlement agreements whose terms are confidential. The mutual cost-bearing order neither confirms nor denies a monetary resolution — it is a standard provision in agreed dismissals and does not indicate which party, if any, received consideration.
Terms undisclosed — private resolution inferredxMatrix permanently relinquishes its claims against Synology
By filing the joint notice and accepting dismissal with prejudice, xMatrix LLC has waived any future right to pursue US8180735B2 or US10630501B2 infringement claims against Synology. This forecloses re-litigation on the same patents against this specific defendant. xMatrix retains the right to assert both patents against unrelated third parties, and any separate licensing programme outside this litigation is unaffected by the order.
Claims against Synology extinguishedSynology obtains certainty — no further exposure on these patents
For Synology, the with-prejudice dismissal provides full litigation closure. Synology faces no risk of re-litigation by xMatrix under US8180735B2 or US10630501B2. The absence of a defendant cost award suggests Synology did not seek fees under 35 U.S.C. § 285 or the court did not find the case exceptional. Companies in the NAS and cloud-backup ecosystem should note that both asserted patents remain active and could be enforced against other defendants.

Official order — verbatim text
The court’s order accepts the parties’ joint notice and dismisses all claims and causes of action with prejudice, with each party bearing its own costs. The phrasing ‘the above-captioned case has been resolved’ in the underlying notice strongly suggests a private settlement, though no terms are disclosed. The mutual cost-bearing order is standard in agreed dismissals and does not reflect a merits determination. No finding of liability, invalidity, or non-infringement was made — the patents’ validity and scope remain legally untested in this proceeding.
US8180735B2 & US10630501B2 — Managed File Backup and Network Gateway Infrastructure
US8180735B2 (Application No. 12/521756) protects a system for managed file backup and restore at remote storage locations, operating through a multi-services gateway installed at user premises. US10630501B2 (Application No. 16/370126) covers a system and method for providing network support services and premises gateway support infrastructure. Together, the patents address the architectural layer between end-user devices and remote storage or service infrastructure — a domain central to NAS appliances, hybrid cloud backup solutions, and managed service provider (MSP) platforms.
These patents sit squarely in a technology area experiencing rapid commercial expansion: enterprise and SMB NAS vendors, cloud backup providers, and MSPs all rely on gateway-mediated remote storage and network support architectures. Synology’s product portfolio — spanning DiskStation NAS, active backup solutions, and network management tools — aligns closely with the claimed subject matter. The patents have not been invalidated by IPR or litigation merits ruling, meaning they retain full presumption of validity and represent a live enforcement risk for any vendor with comparable gateway or managed backup architecture.
Should your NAS or backup product be cleared against US8180735B2 and US10630501B2?
Any company developing or commercialising NAS appliances, premises gateways, managed file backup services, or hybrid cloud storage infrastructure in the US market should assess exposure under US8180735B2 and US10630501B2. These patents were not narrowed, construed, or invalidated in this proceeding — they remain enforceable in their original issued form. The settlement with Synology does not establish a licence or safe harbour for other vendors. Given xMatrix’s demonstrated willingness to litigate in E.D. Texas, proactive FTO analysis is advisable before product launch or market expansion.
PatSnap Eureka’s FTO Search Agent can map your product’s technical architecture against the claim sets of both patents, identify relevant prior art that could support design-around strategies or IPR petitions, and surface related pending applications in the same patent families. For R&D teams building gateway-mediated backup or network support infrastructure, Eureka can flag claim elements most likely to read on gateway orchestration logic, remote storage authentication, and support service provisioning — enabling targeted design decisions before litigation risk materialises.

What this case signals for the NAS and cloud backup IP landscape
Two gateway and file backup patents resolved in under nine months — a pattern worth tracking across the NAS and remote storage sector.
E.D. Texas remains a preferred venue for gateway and backup patent assertions
The Eastern District of Texas continues to attract patent assertion cases in the network infrastructure and data backup space. NAS and cloud storage vendors operating in the US market should monitor docket activity in this court for early signals of emerging assertion campaigns targeting gateway and remote backup architectures.
Pre-claim-construction resolution limits prior art record for the sector
Because this case settled before any claim construction order, there is no judicial interpretation of the key claim terms in US8180735B2 or US10630501B2. This preserves ambiguity in claim scope, meaning third parties cannot rely on a Markman ruling to assess their own exposure — and must conduct independent FTO analysis.
xMatrix v Synology — key questions answered
Dismissal with prejudice is a final, permanent termination of xMatrix’s claims against Synology under US8180735B2 and US10630501B2. xMatrix cannot re-file the same patent infringement claims against Synology in any future action. The order does not reflect a finding on the merits of infringement or validity — it is a procedural conclusion, typically following private settlement.
No. The case was dismissed before any substantive merits ruling, including claim construction. Neither patent was declared invalid, unenforceable, or not infringed. Both patents retain their full presumption of validity and remain enforceable against third parties not party to this dismissal order.
The complaint targeted Synology’s products relating to managed file backup and restore at remote storage locations through a multi-services gateway at user premises, and systems providing network support services and premises gateway support infrastructure — product categories closely aligned with Synology’s NAS and active backup product lines.
Yes. The with-prejudice dismissal extinguishes xMatrix’s claims only against Synology Inc. xMatrix retains full rights to assert US8180735B2 and US10630501B2 against any other party. The resolution with Synology does not constitute a licence or covenant not to sue for other companies in the NAS or managed backup space.
The Eastern District of Texas is a well-established venue for patent infringement suits, known for its plaintiff-friendly procedural history and active patent docket.
