CDN Innovations v. ASUSTeK Computer: Voluntary Dismissal Without Prejudice
CDN Innovations, LLC asserted two patents — US7293291B2 and US7565699B2 — against ASUSTeK’s RT-AX5400 product in the Eastern District of Texas. The case was voluntarily dismissed without prejudice after 196 days, before ASUSTeK filed any answer, leaving the door open for future enforcement.
Pre-answer dismissal in ED Texas router patent dispute
On May 1, 2024, CDN Innovations, LLC filed a patent infringement action in the Eastern District of Texas (Case No. 4:24-cv-00380) before Judge Amos L. Mazzant, asserting US7293291B2 and US7565699B2 against defendants ASUSTeK Computer International and ASUSTeK Computer, Inc. The accused product was ASUSTeK’s RT-AX5400, a Wi-Fi 6 router. CDN Innovations was represented by Devlin Law Firm LLC, a firm with a recognised patent assertion practice.
The case closed on November 13, 2024 — 196 days after filing — when CDN Innovations filed a unilateral notice of voluntary dismissal without prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(i). Because ASUSTeK had not yet served an answer to the complaint, no court order was required. The dismissal notice expressly stated that each party shall bear its own costs, expenses, and attorneys’ fees, suggesting no formal settlement payment was documented in the public record.
A pre-answer dismissal without prejudice is strategically significant: the plaintiff retains the right to refile the same claims against the same defendant at a later date, subject to applicable statutes of limitations. The 196-day duration and the absence of any answer on record suggest the parties may have engaged in early-stage negotiations, though the public record is silent on any underlying agreement. The patents-in-suit remain enforceable, and the RT-AX5400 product line has not received any judicial clearance.

Voluntary dismissal without prejudice: what the record reveals
Rule 41(a)(1)(A)(i): plaintiff’s unilateral right to exit
Under FRCP 41(a)(1)(A)(i), a plaintiff may dismiss an action without a court order by filing a notice of dismissal before the defendant serves an answer or a motion for summary judgment. ASUSTeK had not yet answered, so CDN Innovations exercised this right unilaterally. No judicial approval was required and no merits ruling was issued. The mechanism is procedural — it says nothing about the underlying patent claims.
Pre-answer procedural exitWithout prejudice: CDN Innovations can refile
The dismissal notice explicitly states ‘without prejudice’, meaning CDN Innovations retains the right to bring the same patent claims against ASUSTeK’s RT-AX5400 in a future action. This is distinct from a dismissal with prejudice, which would permanently bar refiling. The public record does not disclose whether a private settlement was reached; the cost-bearing clause (‘each party bears its own costs’) is consistent with either an early settlement or a simple strategic withdrawal.
Refiling rights preservedASUSTeK avoids a merits ruling — for now
ASUSTeK obtained no invalidity ruling, no non-infringement finding, and no fee award. The dismissal provides no judicial shield against a future lawsuit asserting the same patents against the RT-AX5400 or related products. Because ASUSTeK never answered, it also had no opportunity to assert counterclaims. The absence of prejudice to CDN Innovations means ASUSTeK’s exposure to these two patents remains legally unresolved.
No merits adjudicationRT-AX5400 carries unresolved patent risk
The RT-AX5400 product has not been judicially cleared of infringement. US7293291B2 and US7565699B2 remain granted and enforceable. Competitors, resellers, or OEM partners incorporating similar Wi-Fi 6 networking technology should note that CDN Innovations retains a live enforcement posture. Patent assertion entities operating pre-answer dismissals frequently refile — or use the threat of refiling — as negotiating leverage in licensing discussions.

Official order — verbatim text
The dismissal notice invokes Rule 41(a)(1)(A)(i) precisely because ASUSTeK had not yet answered — the procedural predicate is explicitly stated. The ‘without prejudice’ designation is dispositive: CDN Innovations surrenders nothing substantively. The cost-bearing clause is mutual and standard in unilateral pre-answer exits, and does not, on its own, confirm or deny any private settlement. No court order was required and none was issued, meaning Judge Mazzant made no findings on infringement, validity, or claim construction.
US7293291B2 & US7565699B2 — networking and data security technologies
US7293291B2 (application no. US10/623274) and US7565699B2 (application no. US11/897295) are the two patents CDN Innovations asserted in this action. Both patents are issued US grants and carry the full statutory presumption of validity. Their application numbers place their priority dates in the mid-2000s, a foundational period for networked device security and access control technologies that underpin many features now standard in modern Wi-Fi 6 routers such as the RT-AX5400.
From a competitive intelligence standpoint, CDN Innovations’ decision to assert both patents together against a flagship Wi-Fi 6 router suggests the claims are positioned to cover core networking or security functionality rather than peripheral features. Neither patent was subjected to IPR challenge in this proceeding, preserving their validity intact. For networking hardware manufacturers, semiconductor IP licensors, and router OEMs, these patents represent a live assertion risk that has not been judicially resolved.
Should your team run an FTO against US7293291B2 and US7565699B2?
Any company designing, manufacturing, importing, or distributing Wi-Fi 6 routers, access points, or related networking hardware with functionality overlapping the claims of US7293291B2 or US7565699B2 should treat this case as a trigger for an FTO review. CDN Innovations has demonstrated a willingness to file in ED Texas and has preserved all enforcement rights via a without-prejudice dismissal. The RT-AX5400’s exposure has not been adjudicated, and downstream partners may face indemnification calls if litigation resumes.

What this case signals for the Wi-Fi 6 networking IP landscape
A pre-answer voluntary dismissal in ED Texas rarely signals surrender — it often marks a negotiation inflection point.
Pre-answer dismissals by PAEs often precede licensing activity
CDN Innovations’ use of Rule 41(a)(1)(A)(i) before any answer was filed is a recognised playbook for patent assertion entities. The absence of a with-prejudice term and the symmetric cost-bearing clause suggest the parties reached a private arrangement or that CDN Innovations is preserving optionality. Networking hardware makers with overlapping technology should monitor CDN Innovations’ litigation activity closely.
US7293291 and US7565699 remain active enforcement risks
Neither patent was challenged via IPR in this proceeding, and no invalidity argument reached the court. Both patents retain their full legal presumption of validity. Any company selling or distributing 802.11ax (Wi-Fi 6) routers with functionality potentially covered by these claims should commission a freedom-to-operate analysis before the next product cycle.
CDN v Asustek — key questions answered
The case was dismissed without prejudice under FRCP 41(a)(1)(A)(i). CDN Innovations filed a unilateral notice of dismissal before ASUSTeK served an answer. ‘Without prejudice’ means CDN Innovations retains the right to refile the same patent claims against ASUSTeK in the future.
CDN Innovations asserted two patents: US7293291B2 (application US10/623274) and US7565699B2 (application US11/897295). Both are issued US grants covering networking and data security technology and were asserted against ASUSTeK’s RT-AX5400 Wi-Fi 6 router product.
ASUSTeK received no invalidity ruling, no non-infringement finding, and no fee award. Because the dismissal is without prejudice, ASUSTeK has no judicial protection against a future lawsuit asserting the same patents. The company’s exposure to US7293291B2 and US7565699B2 remains legally unresolved.
The voluntary dismissal notice states that each party shall bear its own costs, expenses, and attorneys’ fees. No cost award was made by the court. This mutual cost-bearing arrangement is standard in pre-answer voluntary dismissals and does not confirm or deny any private settlement between the parties.
Yes. Because the dismissal was entered without prejudice, CDN Innovations may refile a new action asserting the same patents against ASUSTeK’s RT-AX5400 or related products, subject to applicable statutes of limitations. The patents remain valid and enforceable, and no licensing or settlement terms are disclosed in the public record.
