Ward Participations v. Samsung: Knox Security Patent Suit Dismissed With Prejudice After 3.7 Years
Dutch IP holding company Ward Participations BV brought a patent infringement action against Samsung Electronics in the Western District of Texas, asserting two network-security patents against the full Samsung Knox device portfolio. After 1,364 days of litigation, the parties stipulated to a mutual dismissal with prejudice — each side bearing its own costs — suggesting a negotiated resolution outside the public record.
Knox Security Platform at the Centre of a 3.7-Year Texas Patent Battle
Ward Participations BV, a Dutch entity holding US intellectual property rights, filed suit on 4 August 2021 in the Western District of Texas against Samsung Electronics Co., Ltd. and its US subsidiary Samsung Electronics America, Inc. The complaint asserted infringement of two issued US patents — US10992480B2 and US11063766B2 — targeting the broad range of Samsung consumer and enterprise devices secured by the Knox security platform. Samsung deployed a large litigation team from Fish & Richardson PC and Gillam & Smith LLP against plaintiff’s counsel at Brown Rudnick LLP, Ramey LLP, and DNL Zito Castellano.
The case closed on 29 April 2025 via a joint stipulation of dismissal with prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(ii). Both parties agreed that all claims and counterclaims — including Samsung’s defensive counterclaims — are permanently extinguished. Notably, the stipulation explicitly carves out European rights and affiliated-company rights, suggesting the parties’ broader IP relationship extends beyond the US proceedings resolved here. Each side bears its own legal costs, which is consistent with a negotiated commercial resolution rather than a capitulation by either side.
At 1,364 days, the duration exceeded what is typical for settled W.D. Texas patent cases, suggesting substantive motion practice or licensing negotiations that extended through multiple stages. The public record does not disclose any financial terms, licence grant, or covenant not to sue, so the commercial outcome remains unknown. The explicit carve-out for European rights is a notable public signal that Ward Participations may pursue or has separately pursued parallel enforcement in European jurisdictions, meaning the competitive dispute between these parties may not be fully resolved.

Dismissed with prejudice by stipulation: what the ruling means for both parties
Rule 41(a)(1)(A)(ii) stipulated dismissal — permanent bar on re-filing
A dismissal with prejudice under Rule 41(a)(1)(A)(ii) is entered by agreement of all parties and operates as a final adjudication on the merits. Ward Participations cannot re-assert US10992480B2 or US11063766B2 against Samsung in US courts on the same claims. The scope is explicitly limited to US IP rights, preserving any parallel proceedings in other jurisdictions.
Permanent US claim barWard forfeits US re-litigation rights but preserves European enforcement
By agreeing to dismissal with prejudice, Ward Participations permanently surrenders the right to re-file these two US patent claims against Samsung entities. However, the stipulation expressly states it has no effect on European rights or rights of related companies. This carve-out is commercially significant and suggests Ward may hold corresponding European patent rights that remain live. Any financial settlement terms are not disclosed in the public record.
European rights preservedSamsung secures permanent US protection for Knox platform devices
Samsung achieves a permanent end to this US infringement action covering the entire Knox-secured device portfolio. The with-prejudice dismissal and own-costs terms mean Samsung faces no monetary judgment and no ongoing royalty obligation from this proceeding. Samsung’s counterclaims — likely validity challenges — are also dismissed, meaning the patents technically survive but cannot be re-asserted in US courts against Samsung. The European carve-out leaves residual competitive risk.
Knox portfolio cleared (US)European carve-out signals continued cross-border IP pressure on Knox ecosystem
The explicit reservation of European rights in the US stipulation is an unusually specific drafting choice and typically signals that parallel or prospective enforcement activity in Europe is either planned or already underway. For Samsung’s enterprise Knox partners and device OEMs, the US resolution provides certainty in American markets but the technology domain — network-layer device security — remains a live area of European patent risk. Competitors in the enterprise mobile security space should monitor corresponding EP filings by Ward Participations.

Official order — verbatim text
The stipulation’s language is broader than a standard settlement: it resolves ‘all claims which could have been made’ with respect to US IP rights, functioning as a covenant of comprehensive US peace. The explicit carve-out for European rights and affiliated-company rights is legally significant — it signals that the dismissal was carefully scoped to the US proceeding only. The own-costs provision, with no fee-shifting, is consistent with a negotiated commercial resolution where neither party conceded liability. No admission of fact or liability was made by either side.
US10992480B2 & US11063766B2 — Network Security and Device Authentication
US10992480B2 (application no. US16/597773) and US11063766B2 (application no. US10/560579) cover network security communications and device authentication technologies. Both patents were asserted against Samsung’s Knox platform — a hardware and software security architecture embedded across Samsung’s consumer and enterprise device portfolio. The application lineage of US11063766 through the US10/560579 series suggests an earlier priority date, which may have been strategically significant in any claim construction or validity dispute.
The Knox platform is a critical commercial differentiator for Samsung in enterprise mobility, supporting government, healthcare, and financial-sector deployments. Patents covering authentication and secure device communication at the platform level carry significant licensing value because they potentially read on hundreds of millions of devices globally. The assertion of both patents together against the full Knox-supported device list — rather than a specific product — indicates a broad claim strategy aimed at platform-level royalties rather than product-specific damages.
Should your product team run an FTO against US10992480B2 and US11063766B2?
Any enterprise mobility vendor, MDM platform developer, or Android OEM implementing hardware-backed key attestation, secure boot, or network-layer device authentication should treat these patents as active FTO considerations. The Knox-level assertion demonstrates that holders of these patents are willing to pursue large-scale litigation in US courts. The fact that Samsung — with substantial litigation resources — chose commercial resolution over full trial suggests the claim scope may be non-trivial.

What this case signals for the enterprise mobile security IP landscape
A 3.7-year Texas patent battle over Knox security patents ends quietly — but the European carve-out keeps the competitive question open.
With-prejudice dismissal ≠ full resolution when European rights are carved out
The stipulation’s explicit preservation of European rights is a red flag for Samsung’s Knox ecosystem partners operating in EU markets. IP teams should identify whether US10992480 and US11063766 have corresponding EP counterparts held by Ward Participations or affiliates, and assess whether European infringement exposure is live.
W.D. Texas remains a credible venue for network-security patent assertions against device OEMs
The 1,364-day lifecycle suggests the case survived early-stage dismissal efforts and generated substantive motion practice. For device manufacturers deploying platform-level security features, this case is a reminder that Dutch and European IP holding companies are active asserters in US courts and are willing to litigate through near-trial timelines.
BV v Samsung — key questions answered
Ward Participations BV asserted two US patents: US10992480B2 and US11063766B2, both covering network security and device authentication technologies. The patents were asserted against the full range of Samsung devices secured by the Knox platform. The case was filed in the Western District of Texas on 4 August 2021.
The case was resolved by a joint stipulation of dismissal with prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(ii), filed 29 April 2025. Each party agreed to bear its own costs and attorneys’ fees. The stipulation explicitly preserved European rights and affiliated-company rights, and no admission of liability was made by either party. Financial terms, if any, were not disclosed.
Yes. A dismissal with prejudice operates as a final adjudication on the merits under US federal law. Ward Participations cannot re-assert US10992480B2 or US11063766B2 against Samsung Electronics Co., Ltd. or Samsung Electronics America, Inc. in US courts based on the same claims. The stipulation also resolves all claims ‘which could have been made’ regarding Ward’s US IP rights against Samsung.
Samsung Knox is a built-in security platform present across Samsung’s consumer and enterprise device lineup, providing hardware-backed security, device authentication, and secure containerisation. It is used in government, healthcare, and enterprise mobile management contexts. Its broad deployment across hundreds of millions of devices makes it a high-value target for platform-level patent assertions, as a single licence could cover an entire product portfolio.
The stipulation of dismissal expressly states it ‘has no effect on any other rights, including any European Rights of either party.’ This language suggests Ward Participations holds or may hold corresponding patent rights in European jurisdictions. The public record does not identify specific EP patent numbers, but the carve-out is a clear signal that European enforcement was deliberately preserved in the US settlement.
