CommWorks Solutions v. AVM GmbH: Six-Patent Wi-Fi Router Dispute Dismissed
CommWorks Solutions, LLC asserted six wireless networking patents against AVM GmbH’s FRITZ!Box router and mesh Wi-Fi product line in the Eastern District of Texas. The plaintiff voluntarily dismissed all claims without prejudice after 158 days, before AVM filed any answer — leaving the door open for refiling.
Six wireless networking patents, 24 FRITZ! products, zero merits ruling
On 13 January 2025, CommWorks Solutions, LLC filed a patent infringement action against AVM GmbH in the Eastern District of Texas before Judge Rodney Gilstrap. CommWorks asserted six US patents — US7027465B2, USRE044904E, US7177285B2, US7911979B2, US6891807B2, and US7463596B2 — covering wireless networking and broadband router technology. The accused products spanned AVM’s entire FRITZ!Box and FRITZ! Repeater ecosystem, including at least 24 distinct products ranging from DSL routers and fiber gateways to mesh repeaters and Wi-Fi USB sticks.
The case closed on 20 June 2025 — just 158 days after filing — when CommWorks filed a Notice of Voluntary Dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(i). Judge Gilstrap acknowledged and accepted the dismissal without prejudice. Critically, AVM GmbH had not yet filed an answer or moved for summary judgment at the time of dismissal, meaning CommWorks retained the right to refile the same claims. Each party was ordered to bear its own costs, expenses, and attorneys’ fees, suggesting no financial settlement terms were publicly disclosed.
Resolution at the pre-answer stage is notable: it suggests the parties may have reached a private commercial arrangement, or that CommWorks reassessed its litigation posture after filing. The public record is silent on whether a licensing agreement was reached. Because the dismissal is without prejudice, CommWorks retains the legal option to refile these claims against AVM or related entities, and the six asserted patents remain live enforcement assets. R&D and product teams in the Wi-Fi router and mesh networking space should monitor CommWorks’ broader patent portfolio accordingly.
Filing to Voluntary dismissal in 158 days
158 days — resolved before AVM filed an answer or any substantive motion
Dismissed without prejudice: what Rule 41 means for both parties
Rule 41(a)(1)(A)(i): dismissal as of right before answer
Under Federal Rule of Civil Procedure 41(a)(1)(A)(i), a plaintiff may voluntarily dismiss its claims without a court order at any time before the defendant serves an answer or moves for summary judgment. Because AVM GmbH had taken neither step, CommWorks exercised this right unilaterally. The court’s role was purely ministerial — it acknowledged and accepted the notice rather than evaluating the merits. No substantive findings were made on infringement, validity, or claim scope.
No merits adjudicationWithout prejudice: the distinction that matters
A dismissal without prejudice means CommWorks is not barred from refiling the same claims against AVM GmbH in the future. This contrasts sharply with a dismissal with prejudice, which would extinguish the claims permanently. The verdict text explicitly states ‘without prejudice,’ so there is no ambiguity in this case. CommWorks retains all six asserted patents as live enforcement assets. The practical implication: AVM and similarly-situated router manufacturers remain exposed to potential refiling or parallel actions.
Claims may be refiledCommWorks exits with patents intact and options open
CommWorks Solutions retains all six asserted patents without any adverse ruling on validity or enforceability. The voluntary dismissal at the pre-answer stage is consistent with either a private licensing resolution or a strategic pause pending reassessment of litigation venue or claim scope. No estoppel or collateral consequences attach to the patents from this dismissal. CommWorks’ freedom to refile — in the Eastern District of Texas or elsewhere — means the enforcement risk for AVM has not been formally extinguished.
Enforcement risk remainsAVM avoids merits ruling but faces residual exposure
AVM GmbH obtained a dismissal without a finding of non-infringement or invalidity — a procedurally neutral outcome rather than a vindication. The cost-bearing order (each party pays its own fees) suggests no exceptional-case finding under 35 U.S.C. § 285. AVM’s FRITZ!Box and FRITZ! Repeater product lines remain theoretically exposed to the same six patents. Companies in adjacent markets — DSL gateways, mesh Wi-Fi, broadband SoC platforms — should treat these patents as active monitoring priorities.

Official order — verbatim text
The verdict text confirms a Rule 41(a)(1)(A)(i) dismissal — a plaintiff-initiated, as-of-right procedural exit taken before any responsive pleading. The phrase ‘without prejudice’ is explicit, preserving CommWorks’ ability to refile. The court made no findings on infringement, claim construction, or patent validity. The cost-bearing order — each party bears its own fees — is standard for Rule 41(a)(1) dismissals and does not imply an exceptional-case finding under 35 U.S.C. § 285. For AVM, the absence of any invalidity or non-infringement ruling means the six patents remain presumptively valid and enforceable against the FRITZ! product line.
US7027465B2 and five further patents — wireless networking and broadband router technology
The six asserted patents — US7027465B2, USRE044904E, US7177285B2, US7911979B2, US6891807B2, and US7463596B2 — span wireless networking, broadband gateway, and router communication technologies. Application dates range from the early-to-mid 2000s, placing them in the formative era of consumer Wi-Fi and DSL broadband deployment. USRE044904E is a reissue patent, indicating the original claims were amended post-grant through USPTO reissue proceedings — a process that can broaden or clarify scope and adds a layer of prosecutorial history relevant to any validity challenge.
These patents collectively cover technology that is foundational to modern Wi-Fi routers, mesh networking systems, and broadband SoC platforms — precisely the product categories at the core of AVM’s FRITZ!Box lineup. For competitors and adjacent manufacturers building Wi-Fi 5/6/6E routers, DSL gateways, cable modems, or mesh repeater systems, this portfolio represents a meaningful freedom-to-operate risk. The breadth of accused products — 24 SKUs spanning DSL, fiber, LTE, DECT, and powerline — suggests claim language potentially broad enough to reach multiple product architectures, not just a single implementation.
Should your team run an FTO against US7027465B2 and the CommWorks portfolio?
If your organisation designs, manufactures, or distributes Wi-Fi routers, broadband gateways, mesh networking systems, or Wi-Fi SoCs, this six-patent portfolio warrants a formal freedom-to-operate review. CommWorks dismissed without prejudice, meaning all six patents are active and unencumbered by any adverse ruling. The accused product set — DSL routers, fiber gateways, LTE routers, mesh repeaters, powerline Wi-Fi adapters, and USB Wi-Fi sticks — is commercially broad enough to implicate most consumer and SMB networking hardware makers.

What this case signals for the Wi-Fi router and mesh networking IP landscape
A pre-answer voluntary dismissal in E.D. Texas typically signals a licensing negotiation, a strategic pivot, or both — rarely a clean exit.
Pre-answer dismissals in E.D. Texas often precede licensing deals
When a plaintiff with a sizeable patent portfolio dismisses before the defendant even answers, the most commercially plausible explanation is a private resolution — whether a license, covenant not to sue, or ongoing negotiation. CommWorks’ retention of all six patents without prejudice means IP teams at router and broadband gateway manufacturers should monitor for subsequent filings against the same or similar product lines.
Six patents across one product ecosystem signals broad claim mapping
Asserting six patents against 24 products — from DSL routers to mesh repeaters and Wi-Fi USB sticks — suggests CommWorks conducted detailed claim mapping across AVM’s hardware lineup. Companies building or selling Wi-Fi 6/6E routers, OFDMA-capable access points, or broadband SoCs should conduct FTO analysis against the asserted portfolio before the next enforcement wave.
CommWorks v AVM — key questions answered
Dismissed without prejudice means CommWorks Solutions voluntarily withdrew all claims under Rule 41(a)(1)(A)(i) without the court making any ruling on infringement or validity. Because the dismissal is without prejudice, CommWorks retains the legal right to refile the same claims against AVM GmbH or other defendants in the future. The six asserted patents remain valid and enforceable.
CommWorks asserted six US patents: US7027465B2, USRE044904E, US7177285B2, US7911979B2, US6891807B2, and US7463596B2. These patents cover wireless networking, broadband router, and gateway communication technologies. USRE044904E is a reissue patent, having undergone additional USPTO examination after original grant.
CommWorks accused at least 24 AVM products, including FRITZ!Box DSL and fiber routers (e.g., 7590 AX, 6690 Cable, 5590 Fiber), FRITZ! Repeater mesh units (e.g., 6000, 3000 AX, 1200 AX), FRITZ!Powerline adapters, FRITZ!WLAN USB sticks, FRITZ!App, FRITZ!DECT 500, and AVM Systems-on-Chips (SoCs).
A voluntary dismissal at the pre-answer stage — before any substantive engagement — is commercially consistent with a private licensing resolution, a covenant not to sue, or a strategic reassessment of litigation posture. The public record does not disclose any settlement terms. Because each party bears its own costs, no fee-shifting signal is available. The dismissal without prejudice means CommWorks retains the option to refile.
Yes. A dismissal without prejudice under Rule 41(a)(1)(A)(i) does not bar refiling. CommWorks could refile the same claims in the Eastern District of Texas or another jurisdiction. However, if CommWorks were to refile and again voluntarily dismiss, a second dismissal would operate as a dismissal with prejudice under the ‘two-dismissal rule’ of Rule 41(a)(1)(B), which would permanently extinguish those claims.
