DatRec v. Capgemini: Secure Network Patent Suit Voluntarily Dismissed Without Prejudice
DatRec, LLC filed suit against Capgemini U.S., LLC in the Western District of Texas asserting US8381309B2, a patent covering methods and systems for secure communication over public networks. The case ended 218 days after filing when DatRec voluntarily dismissed its claims without prejudice before Capgemini served an answer — leaving the door open to future litigation.
Secure-network patent assertion ends before Capgemini files an answer
DatRec, LLC, the holder of US8381309B2, filed this infringement action against Capgemini U.S., LLC in the Western District of Texas on October 8, 2024. The asserted patent covers methods and systems for secure communication over a public network — technology directly relevant to the managed IT services and digital transformation solutions that Capgemini provides to enterprise clients. Ramey LLP, a firm well known for patent enforcement work in the W.D. Texas, represented DatRec throughout the proceedings.
On May 13, 2025, DatRec filed a Notice of Voluntary Dismissal Without Prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(i). Because Capgemini had not yet served an answer or a motion for summary judgment, the dismissal was self-effectuating — no court order was required to terminate the case. The court’s subsequent order, entered May 14, 2025, confirmed the dismissal, denied all pending motions as moot, and directed each party to bear its own costs, expenses, and attorney fees.
At 218 days, the case resolved far earlier than a typical W.D. Texas patent dispute, suggesting that the parties may have reached a private resolution or that DatRec chose to withdraw before incurring the costs of full litigation. The public record is silent on whether any settlement or licensing agreement was reached. Critically, the without-prejudice designation means DatRec retains the right to refile claims against Capgemini, making the underlying IP risk unresolved from Capgemini’s perspective.

Voluntarily dismissed without prejudice: what the Rule 41 exit means for both parties
Rule 41(a)(1)(A)(i): a plaintiff’s unilateral exit right
Fed. R. Civ. P. 41(a)(1)(A)(i) permits a plaintiff to dismiss an action without a court order simply by filing a notice, provided the defendant has not yet served an answer or summary judgment motion. The dismissal is self-effectuating — the case terminates the moment the notice is filed. Here, Capgemini had not answered, so DatRec exercised this right on May 13, 2025. No merits ruling was ever issued.
No merits adjudicationThe public record does not confirm a settlement or bar to refiling
A dismissal without prejudice preserves the plaintiff’s right to refile the same claims. A dismissal with prejudice would extinguish them permanently. The court’s order specifies ‘without prejudice,’ meaning DatRec is not barred from asserting US8381309B2 against Capgemini again. Whether a private licensing deal or settlement accompanied this dismissal is not stated in any public filing — the record is silent on that point.
Refiling risk remainsDatRec exits early, preserving its enforcement options
By dismissing without prejudice before Capgemini answered, DatRec avoids any adverse merits ruling on validity or infringement. The patent US8381309B2 remains intact and enforceable. DatRec retains the freedom to refile against Capgemini, approach other defendants in the sector, or pursue licensing negotiations — a tactically flexible position despite bearing its own legal costs.
Patent remains enforceableCapgemini escapes this round — but the threat is unresolved
Capgemini avoids an infringement finding and bears its own costs, but the without-prejudice dismissal provides no permanent protection. DatRec could refile at any time within applicable limitations. For an IT services firm whose offerings include managed network and cloud infrastructure, the continued enforceability of a secure-communication patent may warrant ongoing monitoring and a considered IP response strategy.

Official order — verbatim text
The court’s order confirms the dismissal was self-effectuating under Rule 41(a)(1)(A)(i) — no merits ruling was issued and no judicial findings on infringement or validity were made. The equal-costs direction is standard in pre-answer voluntary dismissals. The without-prejudice designation is the operationally significant detail: it leaves the underlying patent dispute legally unresolved, and Capgemini has no estoppel or res judicata protection against a future action asserting the same US8381309B2 claims.
US8381309B2 — Methods and systems for secure communication over a public network
US8381309B2 (application number US12/518212) protects methods and systems for conducting secure communication over a public network. The patent’s application-number designation places its priority in the late 2000s, a period when enterprise reliance on internet-facing infrastructure was accelerating and securing data in transit over untrusted networks was a commercially critical problem. The claims sit at the intersection of network security protocol design and data transmission architecture.
For the managed IT services sector — where vendors like Capgemini architect, operate, and secure network environments on behalf of large enterprise clients — a patent covering secure public-network communication methods carries broad potential reach. Any service offering that involves encrypted tunnels, secure API gateways, or protected data flows over the internet could fall within the claim scope, depending on claim construction. That commercial breadth explains why this patent is an attractive enforcement asset for a patent assertion entity, and why IT services companies should treat it as a live risk even after this dismissal.
Should your team run an FTO analysis against US8381309B2?
Any company building, operating, or reselling services that route or protect data over public networks — including managed security providers, cloud platform operators, enterprise VPN vendors, and IT outsourcers — should assess their exposure to US8381309B2. The without-prejudice dismissal means DatRec retains full enforcement rights. With Ramey LLP known for serial filing campaigns in W.D. Texas, other defendants in the IT services and secure-networking space may face similar assertions in the near term.

What this case signals for the secure-network IP enforcement landscape
Early voluntary dismissals in patent cases are rarely neutral events — they typically signal leverage, negotiation, or strategic repositioning.
Pre-answer dismissals often mask private licensing outcomes
When a plaintiff like DatRec drops a case before the defendant even answers, it frequently suggests a licensing discussion concluded — or stalled — off the record. IP teams at IT services firms should treat a without-prejudice dismissal as a pause, not a resolution, and maintain monitoring on the asserted patent.
W.D. Texas remains a high-volume venue for software and network patent assertions
Ramey LLP’s filing activity in the Western District of Texas is well documented. IT services companies operating in managed network, cloud, and cybersecurity spaces should track serial filers in this venue and build early-stage response protocols — including prior art searches and claim mapping — before litigation escalates.
DatRec v Capgemini — key questions answered
DatRec dismissed its infringement claims against Capgemini under Rule 41(a)(1)(A)(i) without prejudice, meaning no merits ruling was issued and DatRec retains the right to refile the same claims in the future. Capgemini has no res judicata or estoppel protection arising from this dismissal.
DatRec asserted US8381309B2 (application number US12/518212), a patent covering methods and systems for secure communication over a public network. The patent’s claims are relevant to enterprise IT services involving encrypted or protected data transmission over internet-facing infrastructure.
The public record does not state a reason. Pre-answer voluntary dismissals under Rule 41(a)(1)(A)(i) are often associated with licensing negotiations, settlement, or a decision to preserve resources while reconsidering litigation strategy. The dismissal being without prejudice suggests DatRec has not permanently abandoned its enforcement position.
DatRec was represented by William P. Ramey III and Ramey LLP, a plaintiff-side patent litigation firm with a high volume of filings in the Western District of Texas. Ramey LLP is widely recognised as an active patent enforcement practice in that venue, particularly for technology and software patent assertions.
Yes. Because the dismissal was without prejudice, DatRec is legally free to refile patent infringement claims against Capgemini based on US8381309B2, subject to applicable statutes of limitations and any private agreements not reflected in the public record. Capgemini cannot rely on this dismissal as a bar to future suit.
