Deepwell IP v. MediaTek: SoC Patent Dispute Settled After 283 Days
Deepwell IP LLC asserted four patents — including a reissue patent — against MediaTek’s ARM-based SoCs, including the MT8186 and Dimensity 1050, deployed in Lenovo Chromebooks and Motorola Edge devices. The parties settled all claims and secured a dismissal with prejudice from Judge Gilstrap in under ten months.
PAE targets MediaTek’s ARM SoC portfolio in E.D. Texas settlement
Filed on 19 September 2023 before Judge Rodney Gilstrap in the Eastern District of Texas, Deepwell IP LLC brought an infringement action against MediaTek Inc. asserting four US patents — USRE044025E, US8415730B2, US7645664B1, and US7149851B1 — directed at semiconductor and SoC architecture. The accused products included MediaTek’s MT8186 and Dimensity 1050 system-on-chips, MediaTek SoCs incorporating ARM cores, and end-products such as the Lenovo Chromebook and Motorola Edge 2022.
The case closed on 28 June 2024 when Judge Gilstrap granted the parties’ Joint Motion to Dismiss with Prejudice, reflecting a negotiated resolution that ‘settled all claims for relief.’ The dismissal with prejudice is a final adjudication on the merits for res judicata purposes, meaning Deepwell IP cannot reassert the same claims against MediaTek in a future action. Each party was ordered to bear its own costs and fees, a common feature of privately negotiated patent settlements.
At 283 days, the resolution is relatively swift for a four-patent E.D. Texas infringement action targeting a major semiconductor company, suggesting the parties may have reached commercial terms early in discovery or at the outset of claim construction proceedings. The financial terms of any licence or lump-sum payment remain confidential, as is typical in patent assertion entity settlements. What drove Deepwell’s selection of these four patents — and whether broader licensing discussions extended to MediaTek’s wider ARM SoC portfolio — is not disclosed in the public record.

Settled and dismissed with prejudice: what the resolution means for both parties
Dismissal with prejudice signals a final, binding resolution
A dismissal with prejudice under Federal Rules of Civil Procedure operates as a final adjudication on the merits. Deepwell IP cannot refile the same patent claims against MediaTek in any US federal court. The Court’s order granting the Joint Motion confirms both parties consented, making this a negotiated exit rather than a court-imposed outcome. The ‘own costs’ order removes any fee-shifting risk for either side.
No re-filing risk for MediaTekDeepwell IP secures a confidential resolution but closes the door on further claims
While settlement terms are not public, the dismissal with prejudice suggests Deepwell IP accepted a negotiated payment or licence in exchange for permanently relinquishing its infringement claims against MediaTek on these four patents. The PAE retains ownership of the patent portfolio and may continue asserting the same patents against other defendants — only MediaTek is barred from future suits on these specific claims.
Portfolio still active vs. third partiesMediaTek obtains finality — but settlement terms remain undisclosed
MediaTek avoids the cost and uncertainty of claim construction, trial, and potential injunctive relief. The with-prejudice bar provides certainty for its MT8186, Dimensity 1050, and ARM-core SoC lines against Deepwell IP specifically. However, the confidential settlement terms — potentially a licence or one-time payment — are not on the public record, and the patents remain valid and assertable against other SoC manufacturers and device OEMs.
Protected on asserted claims onlyOther ARM SoC vendors and OEMs remain exposed to the same patent portfolio
Deepwell IP’s four patents, including reissue patent USRE044025E, remain in force and are not subject to any public disclaimer or dedication. Competitors deploying ARM-based SoC architectures — and the OEMs integrating those chips — should assess their exposure. E.D. Texas settlements of this speed without public claim construction rulings leave the patents’ scope legally untested, typically signalling continued assertion risk for the sector.

Official order — verbatim text
The Court’s order closely mirrors the language of the Joint Motion, confirming this was a fully consensual resolution rather than a contested ruling. The phrase ‘settled all claims for relief’ is legally significant — it encompasses all infringement claims, not merely certain patents or accused products, providing MediaTek with broad closure on the asserted portfolio. The ‘own costs’ directive is consistent with a negotiated commercial resolution where neither party conceded liability, and it removes any basis for post-settlement fee motions under 35 U.S.C. § 285.
USRE044025E — SoC and semiconductor architecture patents in dispute
The four asserted patents — USRE044025E (reissue of an earlier SoC patent), US8415730B2, US7645664B1, and US7149851B1 — span semiconductor and system-on-chip architecture, covering integrated circuit design methods and multi-core processing structures. The reissue patent USRE044025E is particularly notable: reissue proceedings before the USPTO allow claims to be broadened beyond the original grant, potentially capturing more modern chip architectures that were not commercially available at the original filing date.
These patents target a commercially critical segment: ARM-based SoCs powering the Android mobile and Chrome OS compute ecosystem. MediaTek’s MT8186 and Dimensity 1050 are high-volume chips deployed across tens of millions of devices annually. The multi-patent assertion strategy — combining a reissue patent with three utility patents — is consistent with PAE campaigns designed to maximise claim coverage across different technical implementations of ARM core integration, memory architecture, and semiconductor processing methods.
Should your team run an FTO check against USRE044025E and co-asserted patents?
Any company designing, manufacturing, or integrating ARM-based SoCs — or shipping devices powered by MediaTek, Qualcomm, Apple, or similar ARM licensees — should assess freedom-to-operate against Deepwell IP’s four-patent portfolio. The settlement resolved claims only as between Deepwell IP and MediaTek; the patents remain enforceable against all other parties. OEMs shipping Chromebook or Android devices on any ARM SoC architecture are particularly relevant targets given the product categories already accused in this case.
PatSnap Eureka’s FTO Search Agent enables R&D and IP teams to map their SoC product architectures against the claim scope of USRE044025E, US8415730B2, US7645664B1, and US7149851B1 simultaneously. Eureka’s semantic claim analysis can identify which ARM core integration methods, memory subsystems, or processing architectures fall within the literal or equivalent scope of these claims — helping product teams and legal counsel prioritise design-around investments or seek prior art for inter partes review before a demand letter arrives.

What this case signals for the ARM SoC patent licensing landscape
A swift PAE settlement in E.D. Texas on four SoC patents leaves the portfolio legally intact and commercially active against the broader semiconductor industry.
E.D. Texas remains a preferred venue for PAE SoC assertions
Judge Gilstrap’s docket continues to attract patent assertion entity filings targeting semiconductor companies. The court’s familiarity with complex chip architecture disputes and its historically plaintiff-friendly scheduling makes it a recurring battleground for PAE campaigns against fabless IC designers and their OEM customers.
Reissue patents carry heightened claim-scope risk for defendants
USRE044025E is a reissue patent — meaning the original claims were broadened or corrected post-grant, potentially expanding the patent’s reach beyond the original filing. Semiconductor companies facing reissue patents should conduct broadened claim-scope analysis, as the intervening rights doctrine may limit — but not eliminate — infringement exposure for products manufactured before the reissue date.
Deepwell v Mediatek — key questions answered
Deepwell IP asserted four patents: USRE044025E (a reissue patent), US8415730B2, US7645664B1, and US7149851B1. All relate to semiconductor and SoC architecture. The accused products included the MediaTek MT8186, Dimensity 1050, and ARM-core SoCs embedded in the Lenovo Chromebook and Motorola Edge 2022.
The case was resolved by settlement and dismissed with prejudice by Judge Gilstrap on 28 June 2024. Dismissal with prejudice is a final adjudication — Deepwell IP cannot reassert the same claims against MediaTek in any future US proceeding. The settlement terms are confidential. Each party was ordered to bear its own costs and fees.
No. The dismissal with prejudice binds only Deepwell IP and MediaTek. The four asserted patents remain valid and enforceable against other semiconductor companies, OEMs, and device manufacturers. No public claim construction ruling or invalidity finding was made, leaving the patents’ scope legally untested and commercially active.
USRE044025E is a reissue patent, meaning its claims were reviewed and potentially broadened by the USPTO after the original grant. Reissue patents can capture modern product architectures not explicitly contemplated in the original filing. This makes claim-scope analysis more complex for defendants and may expand infringement exposure compared to an unmodified utility patent.
The case was filed in the Eastern District of Texas (Case No. 2:23-cv-00429) and presided over by Judge Rodney Gilstrap, one of the most experienced patent trial judges in the US federal system. The Eastern District of Texas is a frequently selected venue for patent assertion entity filings due to its established patent litigation infrastructure.
