Random Chat, LLC v. Zebra Technologies: Voluntary Dismissal Without Prejudice
Random Chat, LLC asserted US Patent 8,402,099 against Zebra Technologies in the Western District of Texas. After 225 days — and before Zebra filed any answer or summary judgment motion — plaintiff voluntarily dismissed all claims without prejudice under Rule 41(a)(1)(A)(i), leaving the door open to refiling.
Early voluntary exit before Zebra answered: what the record shows
Random Chat, LLC filed this patent infringement action on May 5, 2025, in the Western District of Texas (Case No. 7:25-cv-00211), asserting US Patent 8,402,099 against Zebra Technologies, Corp. Zebra is a publicly traded enterprise technology company known for barcode scanners, mobile computers, and RFID systems. The complaint targeted Zebra’s products and services as listed on its commercial website. Plaintiff was represented by William P. Ramey III of Ramey LLP, a firm frequently associated with NPE-style patent enforcement in Texas federal courts.
On December 15, 2025 — 224 days after filing — Random Chat filed a Notice of Voluntary Dismissal Without Prejudice pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(i). The court confirmed that because Zebra had not yet served an answer or a motion for summary judgment, the notice was self-effectuating and required no court order to terminate the case. The dismissal is without prejudice, meaning Random Chat retains the legal right to refile the same claims against Zebra in the future, subject to applicable statutes of limitations and any other procedural constraints.
The case resolved in roughly seven and a half months, which is relatively swift for patent litigation in the Western District of Texas. The fact that Zebra had not yet answered when the dismissal was filed suggests the parties may have engaged in pre-answer negotiations, though no settlement terms appear in the public record. The cost-bearing order — each party pays its own fees — is standard for Rule 41 voluntary dismissals and does not signal any financial resolution. What drove the withdrawal remains undisclosed; possibilities include licensing discussions, claim scope concerns, or strategic redeployment of enforcement resources.

Voluntarily dismissed: what the Rule 41 exit means for both parties
Rule 41(a)(1)(A)(i): self-effectuating dismissal before answer
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 a motion for summary judgment. Because Zebra had not yet done either, Random Chat’s notice was legally self-effectuating — the case terminated automatically upon filing, with no judicial approval required. This is among the earliest procedural exits available in federal civil litigation.
No court order requiredWithout prejudice — but the record is silent on why
A dismissal ‘without prejudice’ means the plaintiff has not forfeited its right to refile the same patent claims against the same defendant. This contrasts with a ‘with prejudice’ dismissal, which would permanently bar refiling. The public docket does not disclose whether a licensing agreement, settlement payment, or other arrangement accompanied this withdrawal. Practitioners should treat the prejudice distinction as legally significant: Random Chat’s claims against Zebra remain live threats absent a separate covenant not to sue.
Refiling risk remainsZebra exits without a merits ruling — no invalidity finding on record
Zebra Technologies obtained closure of this specific action without any court ruling on infringement or patent validity. While that avoids immediate liability, the absence of an invalidity determination means US8402099B2 remains presumptively valid. Zebra — and any similarly positioned enterprise technology company — cannot rely on this dismissal as precedent against the patent. A subsequent enforcement action by Random Chat would start fresh.
No invalidity record createdUS8402099B2 remains an active enforcement risk for the sector
Because the dismissal is without prejudice and no claim construction or invalidity ruling was issued, US8402099B2 exits this litigation fully intact. Enterprise technology companies operating in the barcode, RFID, and connected-device space — particularly those with Zebra-comparable product portfolios — should treat this patent as a live enforcement threat. The Ramey LLP filing pattern in Western District of Texas courts suggests continued assertion activity is plausible.

Official order — verbatim text
The court’s order confirms the procedural mechanics of Rule 41(a)(1)(A)(i) dismissal: because Zebra had not served an answer or summary judgment motion, Random Chat’s notice was self-effectuating and required no judicial approval. The order’s explicit cost-neutrality clause — each party bears its own fees — reflects the default Rule 41 standard rather than any negotiated outcome. Critically, the court made no ruling on infringement, claim construction, or validity, meaning US8402099B2 emerges from this action with its presumption of validity fully intact and no adverse precedent on record.
US8402099B2 — communications or networked data-sharing technology
US Patent 8,402,099 (application number US12/675,046) is the sole patent asserted in this action. The patent’s title and claim scope relate to communications or data-sharing architectures — consistent with the ‘Random Chat’ entity name suggesting real-time or session-based communication protocols. The application was prosecuted under application number US12/675,046, placing its priority period in the late 2000s, a period of significant development in networked communication and device-connectivity standards relevant to enterprise hardware ecosystems.
The strategic significance of US8402099B2 lies in its potential applicability to enterprise connected-device platforms — including the barcode scanners, mobile computers, and RFID readers that form Zebra Technologies’ core product portfolio. If the patent’s claims cover session management, device communication protocols, or data-relay architectures, a broad range of enterprise technology vendors could face exposure. The without-prejudice dismissal means no invalidity or non-infringement finding exists to limit future enforcement, making independent claim analysis critical for any similarly positioned competitor.
Should your team run an FTO against US8402099B2?
Any enterprise technology company developing or selling products that involve networked communication, device-to-device data sharing, or session-based connectivity should evaluate US8402099B2 as a potential risk. The patent survived this litigation with no adverse rulings. Random Chat’s willingness to assert it against a major player like Zebra Technologies — and then exit without prejudice — suggests the patent may be held in reserve for future licensing or enforcement campaigns targeting similar product categories.
PatSnap Eureka’s FTO Search Agent can map the independent and dependent claims of US8402099B2 against your product architecture, flag overlapping patent families, and surface prior art that could support an invalidity defence or IPR petition. For R&D teams building connected-device or real-time communication features into enterprise hardware or software, running a claim-by-claim FTO now — before a demand letter arrives — is materially cheaper than responding under litigation pressure.

What this case signals for the enterprise tech IP landscape
A pre-answer voluntary dismissal in WDTX rarely signals the end of an enforcement campaign — it typically marks a pause.
Pre-answer exits often precede licensing discussions or refiling
When a plaintiff dismisses voluntarily before the defendant answers, no litigation record is created — no claim construction, no invalidity arguments on the docket. This preserves the patent’s strength for future assertion. Companies in the enterprise scanning and RFID space should monitor Random Chat’s filing activity across all districts.
Cost-neutrality signals no clear winner in early negotiations
The ‘each party bears its own costs’ order is the default under Rule 41 voluntary dismissal and does not indicate Zebra paid a settlement. However, it also does not rule one out — any financial terms would appear in a separate, non-public agreement. IP teams should not read fee neutrality as confirmation that no deal was reached.
Random v Zebra — key questions answered
It means Random Chat withdrew its infringement claims without any ruling on the merits. Under FRCP 41(a)(1)(A)(i), because Zebra had not yet answered, the dismissal was self-effectuating. ‘Without prejudice’ means Random Chat can refile the same claims against Zebra in the future — the patent and the legal right to assert it remain intact.
Random Chat asserted US Patent 8,402,099 (B2), prosecuted under application number US12/675,046. The patent appears to cover communications or networked data-sharing technology. No claim construction ruling was issued in this case, so the precise scope of claims as applied to Zebra’s products remains unadjudicated.
No merits ruling was issued. Zebra did not obtain a finding of non-infringement or invalidity. The case was dismissed voluntarily by the plaintiff before Zebra filed any answer. While Zebra avoided liability in this action, it did not secure a precedential ruling that would bar future assertion of US8402099B2.
The public record does not confirm a settlement. The dismissal was filed as a Notice of Voluntary Dismissal under Rule 41(a)(1)(A)(i), with each party bearing its own costs. Any financial arrangement between the parties would appear in a separate, non-public agreement. The public docket is silent on licensing terms or payments.
Yes, subject to applicable statutes of limitations and any covenant not to sue that may have been privately negotiated. A second voluntary dismissal of the same claims against the same defendant would, however, operate as a dismissal with prejudice under FRCP 41(a)(1)(B) — the so-called ‘two-dismissal rule.’ Random Chat would need to factor this into any refiling strategy.
