Freedom Patents v. MediaTek: Wi-Fi 6 & MIMO Patent Suit Dismissed With Prejudice
Freedom Patents LLC asserted three wireless communication patents — covering IEEE 802.11ax (Wi-Fi 6) and MIMO capabilities — against MediaTek’s Filogic 360 chipset in the Eastern District of Texas. The parties jointly moved to dismiss with prejudice after 210 days, each bearing its own legal fees.
A rapid Wi-Fi 6 chipset patent dispute ends by joint agreement
Filed on 24 April 2025 in the Eastern District of Texas before Judge Amos L. Mazzant, this infringement action saw Freedom Patents LLC assert three US patents — US8514815B2, US8374096B2, and US8284686B2 — against MediaTek Inc.’s Filogic 360 (MT7925) Wi-Fi chipset. The asserted patents relate to IEEE 802.11ax (Wi-Fi 6) standards and MIMO wireless communication capabilities, technology at the heart of modern consumer and enterprise connectivity silicon.
The case closed on 20 November 2025 via a joint motion to dismiss under Federal Rule of Civil Procedure 41. The court ordered all claims dismissed with prejudice, meaning Freedom Patents is permanently barred from reasserting these same claims against MediaTek on the same patents. Notably, both parties agreed to bear their own costs, expenses, and attorneys’ fees — a mutual cost-neutrality clause that suggests a negotiated resolution rather than a contested court defeat.
At 210 days, the matter resolved swiftly relative to typical E.D. Texas patent litigation timelines, which commonly extend well beyond 12 months to trial. The with-prejudice dismissal and mutual cost absorption are consistent with a confidential settlement or cross-license, though the public record is silent on financial terms. What drove the resolution — whether claim construction risk, inter partes review exposure, or a commercial agreement — remains undisclosed.

Dismissed with prejudice: what the joint Rule 41 order means for both parties
Rule 41 with prejudice: a permanent bar on refiling
A dismissal with prejudice under Fed. R. Civ. P. 41 extinguishes the plaintiff’s right to refile the same claims against the same defendant. Unlike a without-prejudice dismissal — which preserves future optionality — this order permanently closes the door on Freedom Patents pursuing US8514815B2, US8374096B2, or US8284686B2 infringement claims against MediaTek in any US federal court.
Permanent claim barFreedom Patents loses enforcement rights against MediaTek
The with-prejudice dismissal forecloses any future litigation against MediaTek on these three patents. Freedom Patents retains the patents themselves and may still assert them against other parties. The mutual cost order avoids a fee-shifting finding under 35 U.S.C. § 285 — suggesting Freedom Patents avoided an ‘exceptional case’ determination, which would have been commercially damaging to its licensing model.
Enforcement rights extinguished vs. MediaTekMediaTek secures permanent freedom to operate on these claims
MediaTek’s Filogic 360 (MT7925) and any products practicing the asserted claims are now shielded from Freedom Patents’ litigation on these three patents. The joint motion structure — rather than a court-decided win — means MediaTek avoids creating adverse claim construction precedent that could complicate the patents’ use against others. Each party bearing its own costs signals a pragmatic, commercially negotiated exit.
Permanent FTO against these patentsWi-Fi 6 chipset makers face continued PAE assertion risk
The swift resolution without merits adjudication means no public claim construction order exists for these 802.11ax/MIMO patents — leaving their scope undefined for the broader market. Other Wi-Fi 6 and Wi-Fi 6E chipset vendors (Qualcomm, Intel, Broadcom) remain potentially exposed to assertion of these same patents by Freedom Patents. The lack of a § 285 fee award also keeps the patents’ litigation economics intact for future campaigns.

Official order — verbatim text
The court’s order tracks the joint motion verbatim, granting dismissal with prejudice under Rule 41 and imposing mutual cost-bearing. The absence of any findings on infringement, validity, or claim scope means the order carries no precedential value on the merits. For MediaTek, the with-prejudice designation provides durable protection; for Freedom Patents, the lack of any § 285 fee award preserves its licensing credibility for future assertion campaigns against other 802.11ax implementers.
US8514815B2, US8374096B2 & US8284686B2 — IEEE 802.11ax MIMO Wi-Fi Technology
The three asserted patents — US8514815B2, US8374096B2, and US8284686B2 — originate from PCT applications filed in 2008–2009, placing their priority dates in the foundational years of MIMO and high-throughput 802.11 development. They cover aspects of IEEE 802.11ax (Wi-Fi 6) wireless communication architecture and multi-antenna (MIMO) transmission techniques. These technologies are now ubiquitous in Wi-Fi chipsets, access points, smartphones, and IoT devices operating on the 6 GHz and sub-6 GHz bands.
The commercial significance of these patents lies in their position within the 802.11ax standard, which underpins the current generation of Wi-Fi infrastructure globally. If any claims read on standard-essential functionality, assertion risk extends to every chipset vendor and OEM implementing Wi-Fi 6 or Wi-Fi 6E. MediaTek’s Filogic 360 (MT7925) is a flagship Wi-Fi 6E + Bluetooth combo chip widely designed into laptops and routers — making it a high-profile and commercially meaningful assertion target.
Should your team run an FTO against US8514815B2, US8374096B2 & US8284686B2?
Any company designing, manufacturing, or selling products incorporating IEEE 802.11ax (Wi-Fi 6 or Wi-Fi 6E) chipsets or MIMO wireless modules should assess exposure to these three patents. The absence of a Markman ruling means claim scope remains undefined — creating genuine uncertainty for product teams. This is particularly relevant for chipset vendors, router OEMs, laptop makers, and access point manufacturers whose products implement 802.11ax PHY or MAC layer features.
PatSnap Eureka’s FTO Search Agent can map the claim language of US8514815B2, US8374096B2, and US8284686B2 against your product’s technical specification, flag prior art that could support IPR petitions, and surface related Freedom Patents LLC filings to assess campaign breadth. Running a structured FTO now — before a demand letter arrives — is materially cheaper than reactive litigation in E.D. Texas.

What this case signals for the Wi-Fi chipset IP landscape
A rapid with-prejudice exit in E.D. Texas over 802.11ax patents carries specific implications for chipset makers and standard-essential patent strategy.
No claim construction = unresolved scope risk for rival chipmakers
Because the case settled before any Markman hearing, the three asserted patents carry no judicial claim construction on record. Competitors shipping IEEE 802.11ax or MIMO silicon should treat these patents as live threats until either IPR invalidation or a court ruling narrows their scope.
Mutual cost absorption signals a structured commercial resolution
When both parties bear their own fees in a with-prejudice dismissal, it typically signals a negotiated outcome — cross-license, lump-sum payment, or covenant not to sue. Freedom Patents avoided a § 285 exceptional-case finding, preserving the viability of its licensing campaign against other targets.
Freedom v Mediatek — key questions answered
Freedom Patents LLC filed a patent infringement action against MediaTek Inc. in the Eastern District of Texas on 24 April 2025, asserting three patents covering IEEE 802.11ax and MIMO Wi-Fi technology against the MediaTek Filogic 360 (MT7925) chipset. The case was dismissed with prejudice by joint motion on 20 November 2025 after 210 days, with both parties bearing their own costs.
Freedom Patents asserted US8514815B2, US8374096B2, and US8284686B2 — three patents originating from PCT applications filed in 2008–2009 covering IEEE 802.11ax (Wi-Fi 6) wireless communication protocols and MIMO multi-antenna transmission technology. The accused product was MediaTek’s Filogic 360 (MT7925) Wi-Fi 6E chipset.
A dismissal with prejudice under Fed. R. Civ. P. 41 permanently bars Freedom Patents from refiling the same claims against MediaTek on these three patents in any US federal court. However, Freedom Patents retains ownership of the patents and may assert them against other defendants not covered by this order.
The mutual cost-bearing order means no fee-shifting was imposed under 35 U.S.C. § 285 (exceptional case) or otherwise. This outcome is consistent with a negotiated commercial resolution — such as a license, lump-sum payment, or covenant not to sue — rather than a unilateral capitulation. The public record does not disclose the financial terms, if any, of the parties’ agreement.
No. Because the case was dismissed before any Markman hearing or merits ruling, no public claim construction order was issued for US8514815B2, US8374096B2, or US8284686B2. The patents’ scope remains legally undefined, and Freedom Patents retains the right to assert them against other 802.11ax implementers including Qualcomm, Intel, Broadcom, and device OEMs. Other vendors should consider proactive FTO analysis or IPR petitions.
