Samsung v. KPN: 8-Patent LTE & D2D Telecom Dispute Dismissed Without Prejudice
Samsung Electronics filed suit against Dutch telecoms operator KPN in the Delaware District Court, asserting eight US patents spanning LTE proximity discovery, machine-type communications, and device-to-device session establishment. The parties jointly moved to dismiss all claims without prejudice after 210 days, with each side bearing its own fees and costs.
Samsung’s Eight-Patent LTE Broadside Against KPN Ends in Joint Retreat
On 1 January 2025, Samsung Electronics Co., Ltd. filed Case No. 1:25-cv-00001 in the United States District Court for the District of Delaware before Judge Colm F. Connolly, asserting infringement of eight US patents against Koninklijke KPN N.V. The patents collectively cover core wireless communication technologies: device-to-device session establishment, machine-type communication activation, operator-assisted key establishment, enterprise service provisioning, LTE proximity discovery and authentication, and user-data transfer in signalling messages.
The case closed on 30 July 2025 when the parties filed a Joint Motion to Dismiss under Federal Rule of Civil Procedure 41. The court ordered all of Samsung’s claims against KPN dismissed without prejudice, with each side bearing its own attorneys’ fees and costs. A without-prejudice dismissal leaves Samsung legally free to refile the same claims in the future, while KPN obtains no binding merits determination that could be used offensively in subsequent proceedings.
The 210-day resolution — before typical Delaware claim-construction milestones — suggests the parties reached an off-record accommodation, potentially a licensing arrangement or cross-licensing agreement, though the public record is silent on any settlement terms. The mutual cost-bearing order is consistent with a negotiated exit rather than a unilateral capitulation. The absence of a merits ruling means the validity and enforceability of all eight asserted patents remain fully intact from a legal standpoint.

Dismissed without prejudice: what the joint exit means for both parties
Rule 41 without prejudice: the door stays open
A dismissal without prejudice under Federal Rule of Civil Procedure 41 terminates the current action but does not adjudicate the merits. Samsung retains the right to refile the same claims against KPN — subject to any applicable statute of limitations or agreed standstill. No claim or issue is extinguished. Courts treat this outcome as a procedural endpoint, not a substantive defeat for either party.
No merits rulingSamsung preserves all eight patent claims for future enforcement
Because the dismissal is without prejudice, Samsung’s eight asserted patents emerge legally unscathed. No invalidity finding, no non-infringement ruling, and no unenforceability determination was entered. Samsung can reassert these patents against KPN or deploy them against other parties in the wireless communications sector. The mutual cost order suggests this was a consensual resolution rather than a forced withdrawal.
Enforcement rights intactKPN avoids a merits loss but gains no defensive precedent
KPN escapes an adverse judgment and avoids fee exposure, but obtains nothing it can cite as binding precedent in future disputes involving these patents. If Samsung refiles — or asserts the same patents through a related entity — KPN would need to relitigate validity and infringement from scratch. Any off-record arrangement reached between the parties would govern the practical truce, though its terms are not publicly disclosed.
No defensive precedentLTE and D2D patent exposure remains live across the telecom sector
The without-prejudice exit preserves Samsung’s ability to run parallel or sequential enforcement campaigns using the same portfolio against other operators and device manufacturers in the LTE, M2M, and D2D space. Competitors and licensees in these technology areas should treat this case as a signal that Samsung is actively monetising its wireless standard-essential and implementation patent portfolio, rather than a withdrawal from enforcement activity.

Official order — verbatim text
The order adopts the parties’ joint motion verbatim, dismissing all of Samsung’s claims without prejudice under Rule 41 and imposing no fee-shifting. The without-prejudice designation is the operative term: it forecloses any res judicata or issue-preclusion argument by either side. The mutual cost order — rather than awarding fees to KPN as the nominally prevailing party — suggests neither side sought to characterise the exit as a victory, consistent with a consensual off-record resolution whose commercial terms remain undisclosed.
US9372098B2 and 7 further patents — LTE, D2D, M2M, and mobile security portfolio
The eight asserted patents span core 3GPP-aligned wireless communication technologies filed across application windows from 2010 to 2016. They cover device-to-device (D2D) session establishment, machine-type communication (MTC/M2M) terminal activation, operator-assisted key establishment for mobile security, enterprise service provisioning, LTE proximity-based services (ProSe) including authentication and link setup, and user-data transfer via network signalling messages. Several align with 3GPP Release 12 and Release 13 specification domains, suggesting potential standard-essential or standard-adjacent status.
For the wireless telecommunications sector, this portfolio represents a multi-layered enforcement asset: it spans both the network infrastructure layer (operator-controlled activation, signalling) and the device layer (D2D authentication, key establishment). Any operator running LTE ProSe or NB-IoT services, any OEM implementing 3GPP D2D or MTC specifications, or any enterprise platform integrating LTE-based IoT connectivity faces potential exposure. The without-prejudice dismissal means Samsung retains full latitude to assert these patents in licensing negotiations or future litigation against other parties.
Should you run an FTO against US9372098B2 and the Samsung LTE/D2D/M2M portfolio?
Any product team building on LTE ProSe, NB-IoT, device-to-device communication protocols, or machine-type communication platforms should treat this portfolio as a live FTO priority. The eight patents cover technologies embedded in widely adopted 3GPP specifications, meaning implementation risk is diffuse — affecting network operators, chipset vendors, IoT platform providers, and enterprise mobility solution vendors alike. The without-prejudice outcome of this case provides no safe harbour for third parties.
PatSnap Eureka’s FTO Search Agent enables R&D and legal teams to map each of the eight Samsung patents against their specific product claims, generate forward citation trees to identify family members and continuations, and flag standard-essential patent registers for 3GPP Release 12–14 overlap. Running a structured FTO before product launch or licensing negotiation entry is materially faster with Eureka’s automated claim-charting and prior-art synthesis capabilities.

What this case signals for the wireless telecom IP landscape
Eight patents, 210 days, zero merits ruling — Samsung’s Delaware filing against KPN sets a clear precedent for portfolio pressure tactics in LTE and M2M licensing.
Without-prejudice exits in Delaware often precede licensing deals — monitor KPN filings
Joint Rule 41(a) dismissals with mutual cost-bearing in Delaware patent cases are strongly associated with negotiated licensing resolutions reached outside the public record. Parties monitoring KPN’s licensing posture in LTE and M2M technologies should track any subsequent cross-licensing disclosures, SEC filings, or patent assignment activity by either party.
All eight Samsung patents retain full enforceability — third-party risk is unchanged
No validity, infringement, or enforceability finding was made against any of the eight asserted patents. Network operators, device OEMs, and M2M platform vendors that practice LTE proximity discovery, D2D session establishment, or machine-type communication activation protocols should assess their exposure to this portfolio independently of this case’s outcome.
Samsung v Koninklijke — key questions answered
A without-prejudice dismissal under Rule 41 means no merits determination was made. All eight Samsung patents — covering LTE D2D, M2M, and mobile security — remain fully valid and enforceable. Samsung retains the right to refile the same claims against KPN or assert the patents against other parties. No issue preclusion or res judicata attaches to this outcome.
Samsung asserted eight US patents: US9372098B2, US9913072B2, US9699820B2, US10103887B2, US9820134B2, US9438572B2, US10419910B2, and US8601141B2. The patents cover device-to-device communication, machine-type communication activation, operator-assisted key establishment, enterprise service provisioning, LTE proximity discovery and authentication, and user-data signalling.
The public record reflects only the joint motion and court order; no settlement terms or licensing agreement have been disclosed. The mutual cost-bearing order and without-prejudice designation are consistent with an off-record commercial resolution — potentially a licensing or cross-licensing arrangement — though this cannot be confirmed from available filings. Resolution before claim construction in Delaware is commonly associated with negotiated outcomes.
No. Because the case was dismissed without prejudice and without any merits adjudication, no finding on validity, infringement, or enforceability was made with respect to any of the eight asserted patents. Third parties cannot cite this case as precedent establishing or negating the validity of Samsung’s LTE, D2D, or M2M patents.
