CommWorks Solutions v. TRENDnet: Six-Patent Wi-Fi Router Dispute Dismissed With Prejudice
CommWorks Solutions, LLC asserted six US wireless networking patents against TRENDnet’s AC1200 Dual Band Router (TEW-813DRU) in the Central District of California. The parties reached a resolution and jointly requested dismissal with prejudice after just 259 days — each side bearing its own attorneys’ fees and costs.
Six-Patent Wireless Networking Claim Ends in Prejudicial Dismissal
On 26 September 2023, CommWorks Solutions, LLC filed suit against TRENDnet, Inc. in the United States District Court for the Central District of California (Case No. 2:23-cv-08048), asserting infringement of six US patents covering wireless networking technologies: US7027465B2, USRE044904E, US7177285B2, US7911979B2, US6891807B2, and US7463596B2. The accused product was TRENDnet’s AC1200 Dual Band Wireless Router (TEW-813DRU), a consumer Wi-Fi device in a highly competitive networking hardware market.
The case closed on 11 June 2024 — 259 days after filing — when the parties jointly announced to the court that they had resolved their dispute and requested dismissal with prejudice. The court granted the request, ordering that all of CommWorks’ claims against TRENDnet be dismissed with prejudice and that each party bear its own attorneys’ fees, costs, and expenses. A dismissal with prejudice is a final adjudication on the merits: CommWorks is permanently barred from reasserting these same claims against TRENDnet on these patents.
The sub-nine-month resolution — before any reported claim construction or summary judgment activity — is consistent with a confidential settlement or licence agreement reached during early litigation stages, though the public record discloses no financial terms. The equal-costs arrangement is a standard mutual concession in agreed dismissals and does not signal a clear winner or loser on the merits. What remains unknown is whether any licence, royalty, or cross-licensing arrangement underpins the resolution.

Dismissed with prejudice: what the joint resolution means for both parties
Dismissal with prejudice ends all claims permanently
A dismissal with prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(ii) or by court order operates as a final judgment on the merits. CommWorks Solutions cannot refile these same patent claims against TRENDnet in any federal court. The joint request and equal-costs order are the hallmarks of a negotiated resolution rather than a unilateral concession.
Permanent bar on refilingCommWorks permanently releases its claims against TRENDnet
By agreeing to dismiss with prejudice, CommWorks Solutions forfeits any right to pursue TRENDnet on these six patents. If a licensing fee was secured before the dismissal request, that would represent the commercial objective of the action — but the public record is silent on financial terms. CommWorks retains all six patents and may continue to assert them against other defendants.
Claims extinguished vs. TRENDnet onlyTRENDnet secures finality — no ongoing infringement exposure on these patents
TRENDnet obtains a permanent bar against CommWorks reasserting the six asserted patents for this product line. The equal-costs order means TRENDnet bears only its own legal spend, with no fee-shifting. Whether TRENDnet secured a licence, design-around rights, or simply negotiated a nuisance-value settlement is not disclosed in the public docket.
Finality for TEW-813DRU product lineSix wireless networking patents remain live enforcement tools against the broader market
Although CommWorks’ claims against TRENDnet are extinguished, all six patents — covering core wireless networking protocols — remain in force and enforceable against other Wi-Fi hardware manufacturers. Competitors shipping AC-standard dual-band routers should treat these patents as active enforcement risk. The swift resolution may embolden similar licensing actions against other consumer networking product vendors.

Official order — verbatim text
The court’s order mirrors the parties’ joint request verbatim, granting dismissal with prejudice and imposing no fee-shifting — a mutual-costs arrangement that is a hallmark of a privately settled dispute. The ‘with prejudice’ designation is critical: it forecloses any future CommWorks action against TRENDnet on these six patents, providing TRENDnet with durable legal finality. The absence of any claim construction record or summary judgment ruling means the validity and scope of the six asserted patents were never adjudicated on the merits in this proceeding.
US7027465B2 and five further wireless networking patents in suit
The six asserted patents — US7027465B2, USRE044904E, US7177285B2, US7911979B2, US6891807B2, and US7463596B2 — span application dates ranging from the early-to-mid 2000s, placing their priority periods at the foundation of modern 802.11 Wi-Fi standardisation. The inclusion of a reissue patent (USRE044904E) is particularly notable: reissue proceedings are used to broaden or clarify original claims, potentially expanding their reach over later-generation hardware. Together, the portfolio targets core wireless LAN communication, dual-band coordination, and network access control functions.
For any manufacturer or vendor shipping 802.11ac (Wi-Fi 5) or 802.11ax (Wi-Fi 6) dual-band routers, this portfolio presents a credible enforcement risk. CommWorks’ selection of TRENDnet’s AC1200 router as the accused product suggests the asserted claims map to standard dual-band wireless routing functionality — not product-specific features — which means the risk is not limited to TRENDnet’s SKUs. The reissue patent in particular warrants close claim-chart analysis against current chipset implementations from Broadcom, MediaTek, and Qualcomm.
Should your team run an FTO against US7027465B2 and the CommWorks portfolio?
Any R&D or product team developing, importing, or distributing 802.11ac or 802.11ax dual-band Wi-Fi routers, access points, or gateway devices in the US market should treat the CommWorks portfolio as an active FTO concern. The swift resolution of this case without merits adjudication leaves the patents’ validity and claim scope entirely intact. The reissue patent (USRE044904E) is particularly high-priority given its broadened claim potential.

What this case signals for the wireless networking IP landscape
A six-patent assertion resolved in under nine months points to a targeted licensing strategy — and a playbook likely to be repeated across the Wi-Fi hardware sector.
PAE enforcement of legacy Wi-Fi patents remains commercially viable
CommWorks’ six-patent assertion against a single consumer router SKU — resolved in 259 days without trial — is consistent with a licensing-first enforcement strategy. Patent assertion entities holding legacy wireless networking IP are finding the C.D. Cal. docket an efficient venue for extracting early resolutions from hardware vendors.
Equal-costs dismissals signal negotiated resolution, not defeat
The mutual fee-bearing arrangement in the court’s order is a standard indicator of a privately negotiated outcome. Neither party’s litigation position should be inferred as weak from this order alone. IP teams tracking CommWorks’ portfolio should note that this case resolves only the TRENDnet exposure — all six patents remain live against others.
CommWorks v Trendnet — key questions answered
The case was dismissed with prejudice on 11 June 2024, approximately 259 days after filing. The parties jointly announced a resolution and requested dismissal, with each side bearing its own attorneys’ fees and costs. The dismissal with prejudice permanently bars CommWorks from reasserting the same claims against TRENDnet.
CommWorks asserted six US patents: US7027465B2, USRE044904E, US7177285B2, US7911979B2, US6891807B2, and US7463596B2. All relate to wireless networking technologies. The inclusion of a reissue patent (USRE044904E) is notable as reissue claims may have broader scope than the original grant.
The accused product was the TRENDnet AC1200 Dual Band Wireless Router, model TEW-813DRU. This is a consumer-grade 802.11ac dual-band Wi-Fi router, suggesting the asserted patent claims target standard dual-band wireless routing functionality rather than product-specific features.
Not necessarily. A dismissal with prejudice extinguishes the specific claims but does not indicate a merits defeat for either party. In patent litigation, dismissals with prejudice following a joint announcement of resolution are typically consistent with a privately negotiated settlement or licence, the terms of which are not publicly disclosed. The equal-costs order supports this reading.
Yes. The dismissal with prejudice applies only to CommWorks’ claims against TRENDnet in this specific action. All six patents remain in force and enforceable against other parties. Manufacturers and distributors of dual-band Wi-Fi routers and access points should treat the CommWorks portfolio as an active enforcement risk and consider conducting FTO analysis against the asserted patents.
