Safilo USA v. KLX Energy Services: Safety Valve Patent Case Dismissed With Prejudice
Safilo USA, Inc. brought a patent infringement action against KLX Energy Services, LLC in the Eastern District of Texas, asserting two patents covering safety valve control systems. After 551 days of litigation, the parties jointly moved to dismiss all claims with prejudice — each side bearing its own costs — consistent with a confidential resolution.
Settlement signals end to E.D. Tex. safety valve patent dispute
On 11 November 2022, Safilo USA, Inc. filed a patent infringement action against KLX Energy Services, LLC in the Eastern District of Texas (Case No. 2:22-cv-00437). The complaint asserted two patents — US9890609B2 and US9671794B1 — both directed at safety valve control systems and methods of use, technology central to oilfield wellhead and completion operations. KLX Energy Services, an oilfield services company, was alleged to have infringed these patents through its field operations.
The case closed on 15 May 2024 when the court granted a joint motion to dismiss all claims with prejudice. Dismissal with prejudice is a final adjudication on the merits: neither Safilo USA nor any successor may reassert the same claims against KLX Energy Services based on the same patents. The court ordered each party to bear its own costs, expenses, and attorneys’ fees — a common cost-splitting arrangement in negotiated patent settlements that avoids further fee litigation.
At 551 days, the case ran through substantial pre-trial activity before resolution, suggesting the parties engaged in at least some discovery and claim construction briefing before reaching terms. The joint motion language — stating the case ‘has been resolved’ — is a standard indicator of a confidential settlement, though no financial terms have been made public. What drove the resolution, and whether a licence or other commercial arrangement underlies the dismissal, remains unknown from the public record.

Dismissed with prejudice: what the joint motion means for both parties
Dismissal with prejudice bars re-filing on these patents
A voluntary dismissal with prejudice under Federal Rules of Civil Procedure operates as a final judgment on the merits. Safilo USA cannot re-file the same infringement claims against KLX Energy Services under US9890609B2 or US9671794B1 in any future action. This is the most final form of voluntary resolution short of a trial verdict, and it was entered jointly — indicating both parties agreed to the terms.
Permanent bar on re-filingSafilo USA gave up future claims in exchange for resolution
By joining the motion to dismiss with prejudice, Safilo USA permanently relinquished the right to pursue infringement claims against KLX under these two patents. This is consistent with a settlement in which the plaintiff received consideration — potentially a licence fee, lump-sum payment, or operational concession — though no terms are disclosed. The cost-bearing arrangement (each side pays its own) suggests neither party was adjudged the prevailing party.
Likely licensed or compensatedKLX Energy Services obtains certainty against these patent claims
KLX Energy Services secured finality: the dismissal with prejudice means Safilo USA cannot reassert US9890609B2 or US9671794B1 against it in the future. Whether KLX obtained a formal licence, agreed to modify its operations, or made a payment is not publicly known. The fact that KLX also agreed to bear its own costs — without seeking fee-shifting under 35 U.S.C. § 285 — suggests the resolution was commercially negotiated rather than litigated to a win.
Claims extinguished permanentlyPatents remain active and enforceable against third parties
Crucially, the dismissal with prejudice only binds Safilo USA and KLX Energy Services inter partes. US9890609B2 and US9671794B1 remain granted, enforceable patents. Safilo USA — or any assignee — retains the right to assert these safety valve control patents against other oilfield services competitors. Companies operating similar wellhead safety valve systems should treat this outcome as a signal that the patent holder is willing to litigate and resolve, not abandon, these rights.

Official order — verbatim text
The court’s dismissal order is formulaic but consequential. The phrase ‘the above-captioned case has been resolved’ — quoted directly from the joint motion — is the parties’ own characterisation, not a judicial finding on the merits. The with-prejudice designation, however, carries full legal force: it functions as a final judgment under Fed. R. Civ. P. 41(a)(2). The cost-neutrality provision, explicitly ordering each party to bear its own fees, forecloses any subsequent § 285 exceptional-case motion. All other pending relief is denied as moot.
US9890609B2 & US9671794B1 — Safety Valve Control Systems
US9890609B2 (Application No. US15/262642) and US9671794B1 (Application No. US15/397488) both protect technology in the domain of safety valve control systems — specifically the systems and methods used to operate, monitor, and control safety valves in oilfield environments. Safety valves are critical wellhead components that prevent uncontrolled hydrocarbon release; their control systems govern actuation, monitoring, and fail-safe response. Patents in this space typically claim both apparatus (the control system architecture) and method (the operational steps), giving the holder broad coverage across hardware and process implementations.
For oilfield services companies, safety valve control technology sits at the intersection of regulatory compliance and operational IP. Both patents were filed in the same application cycle, suggesting a deliberate portfolio strategy to cover complementary aspects of the same core technology. The assertion against KLX Energy Services — a major completion and production services operator — confirms the holder views these claims as commercially enforceable against field-service deployments, not just OEM manufacturers. Any company deploying electronic, hydraulic, or remotely operated safety valve control systems in U.S. oilfield operations should treat these patents as active enforcement assets.
Should you run an FTO against US9890609B2 and US9671794B1?
If your company designs, deploys, or services safety valve control systems for oilfield wellhead applications — including SCADA-integrated, remotely operated, or electronically actuated systems — these two patents represent a concrete freedom-to-operate risk. The fact that the patent holder pursued litigation in E.D. Tex. and obtained a with-prejudice resolution (rather than a defendant win) suggests the claims are taken seriously. Product teams integrating control logic into completion equipment should conduct formal claim mapping before commercial rollout or expansion into U.S. markets.
PatSnap Eureka’s FTO Search Agent can accelerate this process by mapping the independent claims of US9890609B2 and US9671794B1 against your product architecture, identifying potentially overlapping claim elements, and surfacing prior art that may support design-around strategies or validity challenges. Eureka’s patent landscape view also reveals whether additional related patents exist in the same family — critical intelligence when assessing portfolio-level exposure rather than individual patent risk.

What this case signals for the oilfield safety valve IP landscape
A 551-day E.D. Tex. patent dispute ending in joint dismissal with prejudice typically reflects a negotiated commercial resolution — not a clear win for either side.
E.D. Tex. remains a preferred venue for oilfield patent enforcement
The Eastern District of Texas continues to attract patent infringement filings in the oilfield equipment and services sector. Its established patent litigation infrastructure, experienced bench, and plaintiff-friendly reputation make it a strategic choice for technology holders asserting wellhead and safety valve patents against service companies operating in Texas.
Joint dismissal with prejudice signals settlement, not weakness
When both parties jointly move to dismiss with prejudice and each bears its own costs, the public record is silent on financial terms — but the pattern is consistent with a licensing transaction or operational settlement. Competitors should not interpret this outcome as a patent validity finding or a signal that the asserted claims are weak. The patents survive and remain live enforcement tools.
Safilo v KLX — key questions answered
The case was dismissed with prejudice by joint motion on 15 May 2024, after 551 days of litigation in the Eastern District of Texas. Safilo USA asserted patents US9890609B2 and US9671794B1 covering safety valve control systems. The court ordered each party to bear its own costs, consistent with a negotiated resolution. No public terms were disclosed.
Both patents cover safety valve control systems and methods of use in oilfield environments. They protect the architecture and operational methods used to control, actuate, and monitor safety valves at wellheads. The patents were filed under application numbers US15/262642 and US15/397488 respectively, suggesting a coordinated portfolio strategy covering complementary aspects of the same core technology.
No. Dismissal with prejudice in this context is an inter partes resolution only — it bars Safilo USA from re-suing KLX Energy Services on these specific patents, but it makes no finding on patent validity or enforceability. US9890609B2 and US9671794B1 remain granted, active patents and can be asserted against other parties.
Mutual cost-bearing is a standard term in negotiated patent settlements. It avoids the risk of a § 285 ‘exceptional case’ fee motion, which either party might otherwise pursue. By agreeing upfront, both sides achieve finality without further fee litigation. It does not indicate that either party prevailed — it is a commercially neutral resolution mechanism.
Companies deploying safety valve control systems in U.S. oilfield operations face live exposure to US9890609B2 and US9671794B1. The patent holder demonstrated willingness to litigate in E.D. Tex. and reached a resolution (not a validity finding). Any company operating electronically or remotely controlled wellhead safety systems should conduct formal FTO analysis against both patents, particularly if integrating SCADA or digital control architecture into completion equipment.
