Vieri v. EZ Texting: Patent Infringement Suit Ends at 53 Days
Riccardo Vieri filed suit against EZ Texting, Inc. in the Western District of Texas asserting US8156005B2, a patent covering customized advertisement delivery systems. The case closed just 53 days after filing when Vieri filed a voluntary dismissal notice under Rule 41(a)(1)(A)(i) — before EZ Texting filed any answer.
A Swift Exit: Vieri Drops Ad-Tech Patent Suit Against EZ Texting
On April 28, 2025, Riccardo Vieri filed a patent infringement action against EZ Texting, Inc. in the U.S. District Court for the Western District of Texas, Case No. 7:25-cv-00202. The suit asserted US8156005B2 — a patent covering customized advertisement delivery systems — against EZ Texting’s SMS and text messaging marketing platform. Vieri was represented by Garteiser Honea PLLC, a firm with an established practice in patent enforcement litigation.
The case resolved on June 20, 2025, just 53 days after filing, when Vieri filed a Notice of Voluntary Dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(i). The court’s order notes the notice described dismissal ‘with prejudice,’ yet the procedural mechanism invoked — Rule 41(a)(1)(A)(i) — operates as a dismissal without a court order and is self-effectuating. Because EZ Texting had not served an answer or summary judgment motion, no court approval was required. The court ordered each party to bear its own costs and fees.
The 53-day duration is notably short even by pre-answer dismissal standards, suggesting the parties may have reached an off-record resolution, or that Vieri elected to withdraw before EZ Texting mounted any substantive defense. The public record does not disclose whether any licensing agreement, settlement payment, or other commercial arrangement accompanied the dismissal. The critical open question — whether the case can be refiled against EZ Texting — depends on the applicable prejudice standard, which the public record presents with some ambiguity.

Voluntarily dismissed: what the Rule 41 exit means for both parties
Rule 41(a)(1)(A)(i): Self-Effectuating Dismissal
Under FRCP 41(a)(1)(A)(i), a plaintiff may dismiss an action without a court order by filing a notice before the defendant serves an answer or summary judgment motion. The dismissal is self-effectuating — no judicial approval is required. Here, EZ Texting had not yet responded, so Vieri’s notice alone closed the case. The court’s order confirms this procedural posture, citing Fifth Circuit authority from In re Amerijet International.
FRCP 41(a)(1)(A)(i)With or Without Prejudice? The Record Is Unclear
The court’s order highlights a notable tension: Vieri’s notice described dismissal ‘with prejudice,’ yet the court invoked the Rule 41(a)(1)(A)(i) framework — which by default operates without prejudice unless the notice expressly states otherwise. Whether a self-effectuating Rule 41(a)(1) notice can bind the plaintiff to a with-prejudice dismissal is an unsettled procedural question. The public record does not definitively resolve whether Vieri retains the right to refile against EZ Texting on this patent.
Prejudice terms disputedEZ Texting Exits Without Adjudication on the Merits
EZ Texting was never required to file an answer, assert invalidity defenses, or litigate infringement. No claim construction, no discovery, and no merits ruling occurred. While the case is closed, EZ Texting has not obtained a judicial finding of non-infringement or invalidity of US8156005B2. If the dismissal is construed as without prejudice, EZ Texting remains exposed to a potential refiled suit by Vieri or any subsequent holder of the patent.
No merits adjudicationUS8156005B2 Remains a Live Risk for Ad-Tech Platforms
Because US8156005B2 was never adjudicated, its validity and scope remain untested. Other providers of customized advertisement delivery or SMS marketing technology face the same exposure EZ Texting did. The rapid pre-answer dismissal — without a public settlement amount disclosed — leaves open the possibility that this patent may be asserted again, whether against EZ Texting or against other platforms operating in the targeted digital advertising and messaging space.

Official order — verbatim text
The court’s order confirms the case closed via Vieri’s self-effectuating Rule 41(a)(1)(A)(i) notice, requiring no judicial approval. Notably, the order flags that Vieri characterised the dismissal as ‘with prejudice’ — an unusual framing under a mechanism that operates without prejudice by default. This tension is unresolved in the order itself. No merits findings were made: validity, infringement, and claim scope of US8156005B2 remain entirely untested. Each party bears its own costs, consistent with a pre-answer exit absent any fee-shifting trigger.
US8156005B2 — Customized Advertisement Delivery System
US8156005B2, filed under application number US12/206864, covers a customized advertisement delivery system — technology directed at the targeted distribution of advertisements through digital and messaging channels. The patent sits at the intersection of ad-tech and communications infrastructure, a space that encompasses SMS marketing platforms, push notification services, and programmatic advertising systems. Its issuance reflects inventive claims around the logic and mechanics of customising ad delivery to specific recipients or contexts.
For the SMS and digital marketing sector, US8156005B2 represents a potentially broad assertion vehicle given how widely ‘customized advertisement delivery’ functionality is embedded in modern marketing platforms. EZ Texting’s core business — enabling businesses to send targeted SMS campaigns — maps closely to the conceptual space the patent occupies. With no claim construction on record, the patent’s true scope remains commercially ambiguous, making it a credible enforcement risk for any platform that personalises or targets advertising or messaging content.
Should you run an FTO against US8156005B2?
Any company operating a platform that delivers targeted or customised advertisements — particularly via SMS, push notifications, or digital messaging channels — should assess exposure to US8156005B2. The patent’s claims were never construed or adjudicated in this case, meaning no public narrowing interpretation exists. Platforms that personalise ad content, segment audiences, or automate message delivery to specific user groups are within the conceptual perimeter of what this patent may cover.

What this case signals for the ad-tech and SMS marketing IP landscape
A 53-day lifecycle and unresolved prejudice terms make this case a marker worth tracking for digital advertising and messaging platforms.
Pre-answer dismissals rarely signal clean exits for defendants
When a patent plaintiff dismisses before the defendant answers, it typically means no validity or infringement ruling was reached. EZ Texting holds no judicial shield against US8156005B2. Companies in the SMS marketing and customized ad delivery space should treat this outcome as an unresolved risk rather than a cleared threat.
Rule 41 prejudice ambiguity creates strategic uncertainty
The court’s order flags a discrepancy between Vieri’s stated ‘with prejudice’ intent and the default without-prejudice operation of Rule 41(a)(1)(A)(i). Until this is clarified — whether through a follow-on filing or judicial interpretation — neither party has certainty on refiling rights. IP teams monitoring this patent should flag the case as potentially re-activatable.
Vieri v EZ — key questions answered
Riccardo Vieri filed a patent infringement action against EZ Texting, Inc. in the Western District of Texas asserting US8156005B2. The case was voluntarily dismissed after 53 days when Vieri filed a notice under FRCP 41(a)(1)(A)(i) before EZ Texting served an answer. Each party bears its own costs. No merits ruling was issued.
The public record presents an ambiguity. Vieri’s notice described dismissal ‘with prejudice,’ but the court invoked FRCP 41(a)(1)(A)(i), which operates without prejudice by default unless the notice explicitly states otherwise. The court did not resolve this tension directly. Whether Vieri can refile against EZ Texting on US8156005B2 remains an open procedural question based on available records.
US8156005B2 (application no. US12/206864) covers a customized advertisement delivery system — technology relating to targeted distribution of advertisements through digital and messaging channels. EZ Texting operates an SMS marketing platform enabling businesses to send targeted text message campaigns, which places it within the conceptual scope of the patent’s claimed technology. No claim construction was conducted in this case.
FRCP 41(a)(1)(A)(i) allows a plaintiff to dismiss without a court order before the defendant serves an answer or summary judgment motion. The dismissal is self-effectuating and terminates the case immediately. It typically means no invalidity, non-infringement, or claim construction rulings are made. For defendants, it provides no judicial finding protecting against future suit. For patent plaintiffs, it preserves flexibility to refile — unless the notice explicitly states dismissal with prejudice.
Potentially yes. Because the dismissal occurred before any merits adjudication, US8156005B2 was never found invalid or not infringed. EZ Texting holds no court-issued shield against this patent. The ambiguity in the prejudice terms compounds this risk. If the dismissal is construed as without prejudice, Vieri or any future patent holder could refile. EZ Texting and peer SMS marketing platforms should monitor this patent’s enforcement history.
