BillSure LLC v. Amdocs (Israel) Ltd. — Dismissed Without Prejudice in 63 Days
BillSure LLC brought a patent infringement action against Amdocs (Israel) Ltd. in the Eastern District of Texas, asserting US8005457B2 covering methods for verifying network resource usage records. Plaintiff voluntarily dismissed the case without prejudice just 63 days after filing, leaving the door open for refiling.
Early voluntary exit: BillSure retreats before Amdocs could respond on the merits
On January 15, 2025, BillSure LLC filed suit against Amdocs (Israel) Ltd. in the U.S. District Court for the Eastern District of Texas before Judge Rodney Gilstrap, asserting infringement of US8005457B2. The patent covers a method and system for verifying network resource usage records — technology with direct relevance to telecom billing and mediation platforms of the kind Amdocs operates at scale globally.
The case ended on March 19, 2025, when BillSure filed a Notice of Voluntary Dismissal Without Prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(i). Judge Gilstrap accepted and acknowledged the dismissal, denying all pending relief as moot. Because the dismissal was without prejudice, BillSure retains the legal right to reassert the same patent against Amdocs in a future action, subject to applicable statutes of limitations.
A resolution in 63 days — before any substantive briefing or answer on record — strongly suggests the parties reached an understanding outside formal litigation, or that BillSure reconsidered its litigation position upon early case evaluation. The public record does not disclose any settlement terms, licensing agreement, or strategic rationale for the withdrawal, leaving the ultimate commercial outcome between the parties unknown.

Voluntarily dismissed: what the Rule 41 exit means for both parties
Rule 41(a)(1)(A)(i) dismissal: no merits adjudication
A voluntary dismissal under Rule 41(a)(1)(A)(i) is available to a plaintiff as of right before the opposing party has served an answer or a motion for summary judgment. It requires no court approval and results in no judgment on the merits. The court’s role is limited to accepting and acknowledging the notice, which is precisely what Judge Gilstrap did here. No finding of infringement, validity, or invalidity was made.
No merits rulingWithout prejudice: the distinction matters significantly
A dismissal without prejudice preserves the plaintiff’s right to refile the same claims. This contrasts sharply with a dismissal with prejudice, which functions as a final adjudication barring future suit on the same cause of action. The public record is silent on whether any private agreement accompanied this dismissal — it is possible, but not confirmed, that a settlement or licensing arrangement was reached. Parties and counsel should not assume either interpretation without further disclosure.
Refiling right retainedAmdocs exits without admission — but faces ongoing exposure
Amdocs secured dismissal without making any substantive concession on infringement or invalidity. No answer was filed, meaning no declaratory posture was established. However, because the dismissal is without prejudice, Amdocs cannot treat this case as settled IP risk. BillSure retains the right to reassert US8005457B2, and Amdocs should treat the underlying patent as an active risk factor for its network billing and mediation product lines.
No admission; exposure remainsTelecom billing software vendors face persistent assertion risk
US8005457B2 covers core network resource usage verification functionality — a capability embedded in billing mediation, convergent charging, and network audit systems used across the telecom sector. BillSure’s decision to file against a major player like Amdocs, then withdraw without prejudice, is consistent with a testing or licensing strategy. Other vendors operating in this space should assess their exposure to this patent before any potential refiling.

Official order — verbatim text
The court’s order reflects a purely procedural acceptance of BillSure’s voluntary dismissal under Rule 41(a)(1)(A)(i), with no substantive findings on infringement, claim scope, or patent validity. The denial of all pending relief as moot confirms that no injunctive or discovery motions were adjudicated. For Amdocs, the absence of any merits ruling means it carries no estoppel benefit from this proceeding. For BillSure, the without-prejudice posture preserves full enforcement optionality against Amdocs and, implicitly, against the broader market for network usage verification technology.
US8005457B2 — Method and system for verifying network resource usage records
US8005457B2, filed under application number US11/219030, protects a method and system for verifying network resource usage records — a foundational capability in telecom billing infrastructure. The patent addresses how usage data generated by network elements is validated before being rated and billed, a process central to revenue assurance and fraud prevention in carrier-grade systems. Its technical domain sits at the intersection of network management, mediation layer processing, and billing system integrity.
For the telecom software sector, this patent covers functionality embedded in products sold by major vendors including billing mediation platforms, convergent charging systems, and network audit tools. Amdocs, as one of the world’s largest providers of such systems, represents a high-value assertion target. The fact that BillSure selected Amdocs as its defendant suggests the patent holder believes the claims read on commercially deployed products — a view that remains untested on the merits. Competitors operating similar platforms face analogous exposure until the patent is either invalidated or its claim scope is authoritatively construed.
Should your network billing platform be cleared against US8005457B2?
Any organisation developing, licensing, or deploying software that verifies, audits, or validates network resource usage records — including mediation layers, convergent billing engines, and revenue assurance platforms — should assess its exposure to US8005457B2. The patent remains in force with no validity finding against it, and BillSure’s without-prejudice dismissal leaves open the possibility of future assertions against other market participants beyond Amdocs.

What this case signals for the telecom billing software IP landscape
A 63-day voluntary dismissal without prejudice in E.D. Texas suggests calculated positioning rather than a clean exit.
Early E.D. Texas dismissals often precede licensing negotiations or refiling
When a plaintiff dismisses without prejudice before an answer is filed, the case may be part of a broader assertion campaign. BillSure’s rapid withdrawal is consistent with a licensing-first strategy in which litigation serves as a trigger for commercial dialogue. Competitors of Amdocs in the telecom billing and mediation space should assess whether US8005457B2 could be asserted against their own products.
US8005457B2 remains a live enforcement risk for network billing platforms
The patent-in-suit covers a method and system for verifying network resource usage records — directly relevant to mediation, rating, and billing platforms used by telecoms vendors globally. No invalidity finding was made in this case. Product teams building or licensing convergent charging or network audit functionality should conduct a formal FTO review against this patent before extending product scope.
BillSure v Amdocs — key questions answered
BillSure LLC filed a patent infringement action against Amdocs (Israel) Ltd. in the Eastern District of Texas on January 15, 2025, asserting US8005457B2. The case was voluntarily dismissed without prejudice by BillSure on March 19, 2025, just 63 days after filing, before Amdocs filed an answer. No merits determination was made.
A dismissal without prejudice means BillSure retains the right to refile the same infringement claims against Amdocs at a future date, subject to applicable statutes of limitations. No invalidity finding, no claim construction, and no estoppel arose from this proceeding. Amdocs cannot treat this case as a final resolution of its exposure to US8005457B2.
US8005457B2 covers a method and system for verifying network resource usage records — functionality integral to telecom billing mediation, convergent charging, and revenue assurance platforms. Vendors whose products validate or process usage data before billing should assess whether their implementations fall within the patent’s claim scope, particularly given the unresolved assertion against Amdocs.
The public record does not disclose BillSure’s rationale. A pre-answer voluntary dismissal under Rule 41(a)(1)(A)(i) requires no court approval and carries no cost consequences by default. It is consistent with a licensing negotiation having commenced, a strategic reassessment of the case, or a plan to refile with amended claims or in a different venue. No settlement or agreement has been publicly disclosed.
Yes. The voluntary dismissal without prejudice made no finding on the validity or invalidity of US8005457B2. The patent remains in force as issued. Companies seeking to challenge its validity would need to pursue an inter partes review (IPR) petition at the USPTO or assert invalidity as a defence in any future infringement action brought by BillSure.
