Network-1 Technologies v. Foxconn: PoE Patent Dismissed With Prejudice
Network-1 Technologies asserted US6218930B1 — a foundational Power over Ethernet patent — against Foxconn Technology Group in Delaware’s District Court. The case closed after 629 days via a stipulated dismissal with prejudice, with each side bearing its own costs and attorney’s fees.
A 629-Day PoE Patent Dispute Ends in a Clean-Break Stipulated Dismissal
Network-1 Technologies, Inc., a patent licensing entity holding US6218930B1, filed suit against Foxconn Technology Group in the District of Delaware on October 6, 2022, before Judge Maryellen Noreika. The asserted patent claims an apparatus and method for remotely powering access equipment over a 10/100 switched Ethernet network — the foundational technology underpinning the Power over Ethernet (PoE) standard widely deployed in enterprise networking, IP cameras, and industrial IoT.
The case closed on June 26, 2024, when the parties filed a joint stipulation of dismissal with prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(ii). Critically, each side agreed to bear its own costs, expenses, and attorney’s fees. The with-prejudice designation is permanent: Network-1 is barred from refiling this same claim against Foxconn, and no damages award or injunction was entered on the public record.
At 629 days, the case ran considerably longer than a purely procedural dismissal would suggest, indicating that substantive litigation activity — discovery, claim construction preparation, or licensing negotiations — likely occurred before resolution. The mutual cost-bearing structure and absence of any public settlement terms are consistent with a negotiated exit, though the precise commercial terms, if any, remain undisclosed. What drove Foxconn’s exposure and what concessions, if any, were exchanged are not determinable from the public record alone.

Dismissed with prejudice: what the stipulated exit means for both parties
Rule 41(a)(1)(A)(ii) dismissal with prejudice explained
A stipulated dismissal under FRCP 41(a)(1)(A)(ii) requires both parties to sign and file the notice — neither can act unilaterally. The ‘with prejudice’ designation means the claims are extinguished permanently; Network-1 cannot re-file the same patent infringement claims against Foxconn in any court. This is a final adjudication on the merits for res judicata purposes, even though no judge issued a substantive ruling.
Final — no re-filing permittedWith prejudice bars any future assertion against Foxconn
Unlike a without-prejudice dismissal — which preserves the plaintiff’s right to refile — a with-prejudice dismissal permanently extinguishes Network-1’s ability to assert US6218930B1 against Foxconn. For Foxconn, this functions as a full release of liability on this patent. The mutual cost-bearing clause further signals a clean-break resolution: neither party extracted a fee award, suggesting rough litigation parity or a negotiated trade-off outside the public record.
Permanent bar on reassertionFoxconn exits with no damages, no injunction, and no public admission
Foxconn achieves a commercially clean exit: no damages judgment, no injunction affecting its PoE-related products, and no court finding of infringement on the public record. The with-prejudice structure additionally shields Foxconn from any future Network-1 action on this specific patent. Bearing its own legal costs (likely substantial at K&L Gates rates over 629 days) was the visible price of that certainty. Whether a private licensing payment was part of any side agreement is not disclosed.
No liability on public recordPoE patent risk remains live for Foxconn’s industry peers
The dismissal resolves only the Network-1 v. Foxconn dispute — US6218930B1 remains active and enforceable against the broader market. Network-1 has historically asserted this patent across multiple defendants, and the with-prejudice scope is limited to Foxconn. Other PoE device manufacturers, switch vendors, and enterprise networking OEMs should treat this resolution as a signal that Network-1 continues to actively monetise this portfolio rather than a sign that enforcement has ended.

Official order — verbatim text
The stipulated dismissal language is precise and bilateral: both parties agreed under FRCP 41(a)(1)(A)(ii), making the with-prejudice designation binding and court-enforceable. The phrase ‘each side shall bear its own costs, expenses, and attorney’s fees’ explicitly waives any fee-shifting claim under 35 U.S.C. § 285, which would otherwise be available in exceptional patent cases. No infringement finding, validity ruling, or damages award appears anywhere in the disposition — the substantive merits of the PoE patent claims remain judicially unadjudicated.
US6218930B1 — Remote Powering Over 10/100 Switched Ethernet Networks
US6218930B1, filed under application number US09/520350, protects an apparatus and method for remotely powering access equipment over a 10/100 switched Ethernet network — the core technical concept behind what is commercially known as Power over Ethernet (PoE). The patent describes delivering DC power alongside data signalling across standard Ethernet cabling, eliminating the need for separate power infrastructure at network endpoints such as IP phones, wireless access points, and surveillance cameras.
US6218930B1 sits at the foundational layer of the PoE technology stack, predating the IEEE 802.3af standardisation. Network-1 has used this patent as a monetisation vehicle across the broader networking industry, asserting it against multiple defendants. For any company shipping PoE-capable hardware — switches, injectors, IP cameras, access points, or industrial IoT gateways — this patent represents a credible licensing risk that has survived multiple enforcement campaigns. Its commercial relevance spans enterprise networking, smart building infrastructure, and industrial automation sectors.
Should your team run an FTO analysis against US6218930B1?
If your organisation designs, manufactures, or imports PoE-enabled hardware — including managed switches, midspan injectors, wireless access points, IP surveillance cameras, or industrial Ethernet endpoints — US6218930B1 belongs in your freedom-to-operate analysis. Network-1’s active enforcement history across multiple defendants, including this 629-day Delaware proceeding against a major global manufacturer, confirms that this patent is not dormant. The absence of a judicial claim construction in the Foxconn case means the claim boundaries remain undefined from a defendant’s perspective.
PatSnap Eureka’s FTO Search Agent can map US6218930B1’s independent claims against your product architecture, identify prior art that could support an IPR petition, and surface any pending continuations or related family members that may extend the risk horizon. With no Markman order on record from the Foxconn proceeding, a proactive claim scope analysis and prior art landscape report are the most commercially valuable steps a PoE product team can take before Network-1 selects its next enforcement target.

What this case signals for the Power over Ethernet IP landscape
A 629-day dismissal with prejudice in Delaware suggests litigation depth — and a patent that continues to carry licensing leverage across the PoE sector.
US6218930B1 is still enforceable — the risk hasn’t gone away
The with-prejudice dismissal covers only Foxconn. Network-1’s PoE patent remains in force and available for enforcement against other manufacturers. Any company producing PoE-enabled switches, access points, IP cameras, or industrial IoT endpoints should treat this case as a continued enforcement signal, not a resolution of the underlying patent risk.
629 days signals substantive litigation — not a quick walkaway
Cases that settle immediately after filing typically close within 90–180 days. A 629-day duration in Delaware before a stipulated dismissal suggests meaningful litigation activity: claim construction briefing, discovery, or extended licensing negotiations. This timeline implies Foxconn invested significantly in its defence, and Network-1 encountered real resistance before agreeing to exit.
Network-1 v Foxconn — key questions answered
The with-prejudice dismissal permanently bars Network-1 Technologies from reasserting US6218930B1 against Foxconn Technology Group in any court. Filed under FRCP 41(a)(1)(A)(ii), it is a bilateral stipulation carrying res judicata effect — effectively a final judgment on the merits without any court ruling on infringement or validity. Each party bears its own costs and attorney’s fees.
Yes. The with-prejudice dismissal in Case No. 1:22-cv-01320 resolves only the dispute between Network-1 Technologies and Foxconn Technology Group. US6218930B1 remains an active, enforceable patent against all other parties in the market. Network-1 retains full rights to assert the patent against other PoE hardware manufacturers, switch vendors, and networking OEMs.
A 629-day duration before a stipulated dismissal in Delaware is longer than typical quick-exit settlements, suggesting substantive litigation activity occurred — potentially including discovery, claim construction preparation, or extended licensing negotiations. The public record does not disclose whether a private settlement payment was made, but the timeline is consistent with a negotiated resolution reached after meaningful bilateral engagement.
US6218930B1, filed as application US09/520350, covers an apparatus and method for remotely powering access equipment over a 10/100 switched Ethernet network — the foundational concept behind Power over Ethernet (PoE). The patent predates the IEEE 802.3af standard and has been asserted by Network-1 Technologies across multiple enforcement actions targeting PoE-enabled hardware manufacturers and network equipment vendors.
No Markman order or claim construction ruling appears on the public record for Case No. 1:22-cv-01320. The case was dismissed via stipulation before any judicial claim construction was issued. This means the scope of US6218930B1’s claims was not constrained or defined by Judge Noreika, leaving claim boundaries open for future defendants to contest — or risk — in subsequent proceedings.
