Netflix v. Broadcom: 5-Patent VMware & Ethernet Infringement Suit Ends in Defendant Win
Netflix, Inc. asserted five patents covering VMware NSX/NSX-T load balancing, subnet provisioning, and Ethernet switching products against semiconductor and infrastructure giant Broadcom, Inc. in the Northern District of California. After Netflix’s First Amended Complaint was dismissed and its remaining claims stipulated away with prejudice, the court entered final judgment for Broadcom — closing the case in 218 days.
Netflix’s Multi-Patent VMware Campaign Collapses Before Trial
Netflix, Inc. filed suit on April 29, 2025 in the Northern District of California, asserting five U.S. patents — US7656751B2, US7313102B2, US10331472B2, US7447931B1, and US7649912B2 — against Broadcom, Inc. The complaint targeted Broadcom’s VMware Cloud Foundation suite, VMware NSX/NSX-T Data Center, VMware Avi Load Balancer, and a broad range of Ethernet switching silicon including the BCM56070, BCM88690, StrataDNX devices, and associated firmware products deployed across major cloud platforms.
The case ended decisively in Broadcom’s favour. On October 29, 2025, the court dismissed Netflix’s First Amended Complaint. Netflix filed a Second Amended Complaint, but rather than proceed, the parties entered a joint stipulation of dismissal with prejudice as to all remaining claims. On November 18, 2025, Judge Trina L. Thompson entered final judgment under Federal Rule of Civil Procedure 58 in favour of Broadcom and against Netflix, with the clerk directed to close the file.
Resolving in just 218 days — well inside the Northern District of California’s typical patent lifecycle — the swift closure suggests the dismissal of the FAC may have exposed fundamental pleading or infringement-theory weaknesses that made continued litigation untenable for Netflix. The public record does not disclose whether financial settlement terms accompanied the with-prejudice stipulation, but the absence of any damages award or injunction is notable given the breadth of the original product allegations.

Judgment for Broadcom: what the defendant win means for both parties
FAC dismissal plus with-prejudice stipulation sealed Netflix’s loss
The outcome combined two distinct procedural events: the court’s own dismissal of Netflix’s First Amended Complaint on October 29, 2025, followed by a joint stipulation dismissing the Second Amended Complaint with prejudice. A with-prejudice dismissal is a final judgment on the merits — Netflix cannot refile the same claims against Broadcom in any federal court. Judgment was formally entered under FRCP 58, making it immediately appealable.
Final judgment on meritsNetflix walks away with no infringement finding and no damages
Netflix asserted five patents spanning load balancing, subnet provisioning, timing synchronisation, and Ethernet switching. Judgment against Netflix means none of those asserted claims was adjudicated as infringed. The with-prejudice bar forecloses re-litigation of these specific claims against Broadcom, materially limiting Netflix’s near-term enforcement leverage over the VMware product stack and Broadcom’s Ethernet portfolio.
No damages awardedBroadcom secures clean judgment protecting its VMware and silicon portfolio
Broadcom obtains a federal judgment in its favour without ever reaching claim construction or trial, shielding VMware Cloud Foundation, NSX/NSX-T, Avi Load Balancer, StrataDNX, and associated Ethernet products from the asserted patent claims. The with-prejudice result also signals that any appeal by Netflix would face the significant hurdle of justifying reinstatement after a voluntary stipulation.
Portfolio-wide protectionBroadcom’s cloud infrastructure stack faces no immediate patent cloud
Enterprises deploying VMware NSX on AWS, Azure, Google Cloud, or Oracle Cloud — and OEMs integrating Broadcom Ethernet silicon — can proceed without the uncertainty of an active injunction threat tied to these five patents. However, the patents themselves remain in force; Netflix or a future assignee could assert them against other implementers of similar networking and switching technologies not covered by this judgment.

Official order — verbatim text
The November 18, 2025 judgment is unusually explicit in tracing its procedural lineage: it references the October 29 FAC dismissal order (Dkt. 73) and the parties’ joint stipulation on the SAC (Dkt. 76) as twin bases for the Rule 58 entry. This structure suggests the court found Netflix’s amended pleadings substantively insufficient, and that Netflix — rather than face a third dismissal or adverse claim construction — elected to exit via stipulation. The with-prejudice designation converts the stipulation into a merits judgment, foreclosing any re-filing of these specific claims against Broadcom.
US7656751B2 — network load balancing and VMware NSX data plane technology
The five asserted patents span a wide technical footprint: load balancing and session distribution (US7656751B2, application filed 2008), subnet provisioning in SDNs (US7313102B2, filed 2003), virtual machine scheduling and cloud resource allocation (US10331472B2, filed 2017), fault-tolerant network redundancy (US7447931B1, filed 2006), and IEEE 1588 PTP timing synchronisation in Ethernet networks (US7649912B2, filed 2005). Together they represent foundational networking and virtualisation concepts that predate the VMware NSX architecture by years.
The breadth of the assertion — spanning VMware’s software-defined networking stack and Broadcom’s Ethernet silicon — signals Netflix’s attempt to establish foundational patent leverage over cloud infrastructure that runs on the majority of enterprise hybrid cloud deployments. Broadcom’s VMware portfolio now underpins workloads on AWS, Azure, Google Cloud, Oracle Cloud, IBM Cloud, and Alibaba Cloud, making the commercial stakes substantial. The rapid collapse of the case, however, suggests the patents may face significant scope or validity challenges in claim construction.
Should your team run an FTO against these five Netflix networking patents?
Any vendor or cloud operator deploying software-defined networking, load balancing, subnet provisioning, or IEEE 1588 PTP timing in their infrastructure stack should assess exposure to US7656751B2, US7313102B2, US10331472B2, US7447931B1, and US7649912B2. The judgment protects Broadcom’s specific product lines — it does not extinguish the patents or bind third parties. Competing SDN platforms, hyperscaler-adjacent vendors, and network silicon OEMs remain potentially exposed.

Pleading failures in complex multi-patent cases can collapse campaigns early
The court dismissed the FAC before Netflix could even stabilise its complaint. In N.D. California, detailed infringement contentions and claim charts must survive early judicial scrutiny. Companies asserting broad portfolios across diverse product lines — load balancers, silicon, firmware — must ensure each claim maps tightly to accused functionality from the outset.
With-prejudice stipulations carry permanent strategic cost for patent holders
Netflix’s decision to stipulate away its Second Amended Complaint with prejudice forecloses re-assertion of these five patents against Broadcom. Patent owners considering stipulated dismissals after a failed FAC should model the long-term portfolio cost — particularly where the defendant’s products span major cloud infrastructure that may grow in value over time.
Netflex v Broadcom — key questions answered
Judgment was entered in favour of Broadcom, Inc. on November 18, 2025. The court had previously dismissed Netflix’s First Amended Complaint, and the parties then filed a joint stipulation dismissing all remaining claims in the Second Amended Complaint with prejudice. The case was closed after 218 days.
Netflix asserted five patents: US7656751B2 (network load balancing), US7313102B2 (subnet provisioning in SDNs), US10331472B2 (virtual machine scheduling/cloud resource allocation), US7447931B1 (fault-tolerant network redundancy), and US7649912B2 (IEEE 1588 PTP timing in Ethernet). All claims were dismissed with prejudice.
Netflix accused Broadcom’s VMware Cloud Foundation, VMware NSX/NSX-T Data Center, VMware Avi Load Balancer, and Ethernet switching products including BCM56070, BCM88690, BCM88860, StrataDNX devices, BroadPTP 1588 Software Suite, BroadSync firmware, and various PHY and Roboswitch products. The products are deployed across AWS, Azure, Google Cloud, Oracle Cloud, IBM Cloud, and Alibaba Cloud.
No. The Rule 58 judgment binds only the named parties — Broadcom, Inc. and Netflix, Inc. The five asserted patents remain enforceable against third parties. Cloud operators and hardware vendors deploying comparable SDN, load balancing, or PTP timing technologies should independently assess their freedom-to-operate position.
The public record suggests the court found Netflix’s First Amended Complaint insufficient on October 29, 2025 — likely due to pleading or claim-mapping deficiencies common in complex multi-patent infrastructure cases. After the FAC dismissal, Netflix filed a Second Amended Complaint but then stipulated to its dismissal with prejudice, consistent with a decision that further amendment was unlikely to survive judicial scrutiny or that settlement resolved underlying issues.
