Freedom Patents v. Broadcom: Wi-Fi 6E Chipset Infringement Dismissed With Prejudice
Freedom Patents, LLC filed a three-patent infringement action against Broadcom, Inc. in the Eastern District of Texas, targeting the BCM4389 Wi-Fi 6E and Bluetooth 5 combo chipset. The case was dismissed with prejudice after just 138 days — closing the door permanently on these specific claims against Broadcom.
Three Wi-Fi Patents, One Chipset, and a Permanent Bar in East Texas
Freedom Patents, LLC filed this infringement action on 24 April 2025 in the Eastern District of Texas before Judge Amos L. Mazzant, asserting three U.S. patents — US8514815B2, US8374096B2, and US8284686B2 — against Broadcom, Inc. The patents-in-suit relate to wireless networking technologies, and the accused products include the Broadcom BCM4389 Wi-Fi 6E and Bluetooth 5 combo chipset and its associated MIMO Wi-Fi capabilities — a component widely deployed in consumer electronics and enterprise networking hardware.
The case closed on 9 September 2025, with the court ordering that all of Freedom Patents’ claims for relief against Broadcom be dismissed with prejudice. A dismissal with prejudice is a final adjudication on the merits for procedural purposes, permanently barring the plaintiff from refiling the same claims against the same defendant. This outcome is categorically adverse to the patent holder: unlike a voluntary dismissal without prejudice, Freedom Patents has no avenue to reassert these three patents against Broadcom on the same grounds in any future action.
The resolution timeline of 138 days is notably short for E.D. Texas patent litigation, which typically runs considerably longer before trial or settlement. This compressed duration suggests the parties may have reached a negotiated resolution — potentially including licensing terms not reflected in the public record — or that a procedural or substantive deficiency in Freedom Patents’ claims was identified early. The precise driver of the dismissal-with-prejudice order is not disclosed in the publicly available record, leaving the commercial terms, if any, unknown.

Dismissed with prejudice: what the court’s order means for both parties
Dismissal with prejudice forecloses all future claims on these patents against Broadcom
A dismissal with prejudice operates as a final judgment on the merits. Under federal res judicata doctrine, Freedom Patents is permanently barred from asserting US8514815B2, US8374096B2, and US8284686B2 against Broadcom in any subsequent action on the same grounds. This is distinct from a voluntary dismissal without prejudice, which would preserve the right to refile. The court’s order language — ‘dismissed with prejudice’ — is unambiguous and legally conclusive.
Permanent bar on refilingFreedom Patents loses all litigation leverage against Broadcom on these three patents
For Freedom Patents, the with-prejudice dismissal extinguishes enforcement rights against Broadcom under these three patents. Whether a private settlement or licensing deal accompanied the dismissal is not disclosed in the public record — a common feature of PAE-driven resolutions. If no consideration was exchanged, this represents a complete loss of the infringement action. Freedom Patents retains the patents and may assert them against other defendants, but Broadcom is now shielded permanently from these specific claims.
No refiling against BroadcomBroadcom secures permanent protection on BCM4389 from these patent claims
Broadcom, represented by Kilpatrick Townsend & Stockton, achieved a with-prejudice dismissal — the strongest defensive outcome short of a declared invalidity judgment. The BCM4389 Wi-Fi 6E and Bluetooth 5 chipset is no longer exposed to infringement liability under these three patents. Given Broadcom’s scale and the chipset’s broad deployment, this outcome eliminates a recurring litigation risk that could otherwise have been used as leverage across product generations or licensing negotiations.
BCM4389 shielded permanentlyWi-Fi 6E chipset vendors should note that these patents remain active against others
The dismissal protects only Broadcom. Freedom Patents retains ownership of all three patents and may assert them against other Wi-Fi 6E and MIMO chipset manufacturers, module integrators, or OEM device makers. Companies building products around similar wireless networking architectures — particularly those incorporating MIMO or multi-band Wi-Fi 6E functionality — should treat this case as a signal that these patents are being actively enforced and conduct FTO analysis accordingly.

Official order — verbatim text
The court’s order — that Freedom Patents’ claims for relief against Broadcom are dismissed with prejudice — is unambiguous in its finality. The with-prejudice designation means the dismissal carries res judicata effect, permanently precluding Freedom Patents from reasserting these three wireless networking patents against Broadcom on the same or substantially similar grounds. For Broadcom, the order provides durable legal certainty for the BCM4389 product line. The order does not speak to validity, claim scope, or any monetary terms, leaving open the question of whether confidential commercial consideration accompanied the resolution.
US8514815B2, US8374096B2 & US8284686B2 — Wireless Networking and MIMO Technologies
The three patents-in-suit — US8514815B2, US8374096B2, and US8284686B2 — were filed as U.S. national phase applications (application numbers 12/088285, 12/094441, and 12/293458 respectively), suggesting PCT origins and international filing strategies consistent with foundational wireless networking IP. The patents cover wireless networking data transmission, multi-band communication protocols, and MIMO spatial multiplexing — core technical capabilities underpinning Wi-Fi 6E (802.11ax) and Bluetooth 5 combo chipsets such as the accused Broadcom BCM4389.
MIMO and Wi-Fi 6E technologies are foundational to a broad range of consumer electronics, enterprise networking equipment, automotive connectivity modules, and IoT devices. Patents covering these technical layers carry significant enforcement leverage because chipset-level implementations cascade through entire OEM supply chains. Freedom Patents’ decision to assert all three patents against a single high-profile Broadcom chipset suggests a coordinated portfolio enforcement strategy targeting the Wi-Fi 6E market — a sector growing rapidly as 6 GHz band deployments expand globally.
Should your team run an FTO against US8514815B2, US8374096B2, and US8284686B2?
Any company designing, manufacturing, or integrating Wi-Fi 6E chipsets, MIMO-capable wireless modules, or Bluetooth/Wi-Fi combo solutions should treat these three patents as active enforcement risks. The Broadcom dismissal protects only Broadcom — Freedom Patents retains full enforcement rights against all other parties. Module vendors, OEM device makers, and system integrators sourcing Wi-Fi 6E components from any chipmaker other than Broadcom (and potentially even those using Broadcom chips in different product contexts) should assess their exposure.
PatSnap Eureka’s FTO Search Agent can map the claim scope of all three patents against your product architecture, identify prior art that may support validity challenges, and surface related patent families that may be co-asserted in future actions. Given that these patents appear to have PCT origins, international FTO coverage — particularly for products sold in EU, APAC, and US markets — is also advisable. Eureka’s cross-jurisdictional patent database enables a single integrated FTO workflow across all relevant geographies.

Cases involving wireless networking and MIMO patent assertions filed in the Eastern District of Texas against semiconductor and chipset companies, relevant to Freedom Patents v. Broadcom.
What this case signals for the Wi-Fi 6E and wireless chipset IP landscape
A rapid dismissal with prejudice in E.D. Texas suggests either a quiet settlement or a decisive early-stage defeat for a patent assertion entity.
PAE enforcement of wireless MIMO patents is active in E.D. Texas
Freedom Patents’ choice of E.D. Texas and the rapid case lifecycle is consistent with PAE enforcement strategy — file quickly, assert broadly, and resolve before costly discovery. Wi-Fi 6E chipset and MIMO patent holders are active in this court. Semiconductor companies and OEMs deploying BCM4389-class chipsets should monitor dockets for follow-on assertions against other defendants using these same three patents.
With-prejudice dismissal after 138 days typically signals a confidential deal or early fatal flaw
When a PAE case closes this quickly with prejudice, two scenarios are most common: a confidential licensing or lump-sum settlement — with the with-prejudice dismissal as the closing mechanism — or an early identification of a claim defect such as subject-matter eligibility or standing. Neither scenario is confirmed by the public record. The absence of a fee award, however, suggests the court did not find the case exceptional under 35 U.S.C. § 285.
Freedom v Broadcom — key questions answered
A dismissal with prejudice in this case means all of Freedom Patents’ infringement claims under US8514815B2, US8374096B2, and US8284686B2 against Broadcom are permanently terminated. Freedom Patents cannot refile these same claims against Broadcom. The order operates as a final judgment for res judicata purposes, though it does not adjudicate patent validity.
The accused products include the Broadcom BCM4389 Wi-Fi 6E and Bluetooth 5 combo chipset and its associated MIMO Wi-Fi capabilities. The BCM4389 is a widely deployed wireless connectivity chip used in consumer electronics and enterprise devices supporting the 802.11ax (Wi-Fi 6E) standard.
Yes. The with-prejudice dismissal shields only Broadcom, Inc. from these specific claims. US8514815B2, US8374096B2, and US8284686B2 remain valid and enforceable patents that Freedom Patents may assert against any other party. Other Wi-Fi 6E chipset vendors, module makers, and OEM device manufacturers remain potentially exposed.
The 138-day resolution is notably short for E.D. Texas patent litigation. This timeline is consistent with two scenarios: a confidential licensing or settlement agreement that used the with-prejudice dismissal as the closing mechanism, or early identification of a dispositive legal or factual defect in Freedom Patents’ case. The public record does not disclose which scenario applies, and no fee award was recorded.
