TOT Power Control v. Intel: Wireless Power Control Patents Voluntarily Dismissed
Spanish IP firm TOT Power Control, S.L. asserted two patents covering outer loop power control methods for wireless communications against Intel Corp. in California’s Northern District. The case ended in a voluntary dismissal just 63 days after filing, leaving the terms — and whether settlement drove the exit — undisclosed in the public record.
A 63-day infringement sprint ends in voluntary exit — terms undisclosed
On 1 April 2024, TOT Power Control, S.L., a Spanish power-control IP licensing entity, filed an infringement action against Intel Corp. in the Northern District of California (Case No. 4:24-mc-80079) before Judge Kandis A. Westmore. The suit asserted two patents — US7496376B2 and US7532865B2 — both directed at outer loop power control methods and devices for wireless communications systems, technologies directly relevant to Intel’s wireless chipset portfolio.
Sixty-three days after filing, on 3 June 2024, TOT Power Control invoked Rule 41(a)(1)(A)(i) of the Federal Rules of Civil Procedure to voluntarily dismiss the action. This procedural mechanism, available before a defendant serves an answer or a motion for summary judgment, allows a plaintiff to exit unilaterally. The public record does not specify whether the dismissal was with or without prejudice, meaning it is unclear whether TOT retains the right to refile the same claims against Intel.
The compressed 63-day lifespan is consistent with one of several scenarios: early-stage settlement negotiations that concluded quickly, a strategic decision to refile in a more favourable venue or forum, or a reassessment of claim scope following initial case evaluation. Without a court order specifying prejudice terms, independent confirmation of any private resolution is unavailable. The absence of any fee-shifting or sanctions order suggests the exit was uncontested and procedurally clean.

Voluntarily dismissed: what Rule 41 exit means for both parties
Rule 41(a)(1)(A)(i): plaintiff’s unilateral exit right
Rule 41(a)(1)(A)(i) permits a plaintiff to dismiss an action without a court order by filing a notice before the defendant serves an answer or motion for summary judgment. TOT Power Control exercised this right on 3 June 2024. The dismissal is procedurally straightforward and requires no judicial approval, but its prejudice status — which determines whether the same claims can be refiled — is not stated in the public record.
Procedural dismissalWith or without prejudice? The public record is silent
A dismissal ‘with prejudice’ permanently bars TOT from bringing the same patent claims against Intel. A dismissal ‘without prejudice’ preserves that right. Under Rule 41(a)(1)(B), a plaintiff’s first voluntary dismissal is presumed without prejudice unless the notice specifies otherwise. However, the filed notice in this case does not publicly confirm either status, and no court order clarifying the terms is visible in the docket. Practitioners and competitors should not assume either outcome.
Prejudice status unconfirmedTOT exits cleanly — future enforcement options likely preserved
Because Rule 41(a)(1)(A)(i) dismissals are typically presumed without prejudice on a first filing, TOT Power Control likely retains the ability to reassert US7496376B2 and US7532865B2 against Intel in another forum — including via ITC proceedings, a refiled district court action, or potentially in a different jurisdiction. The speed of dismissal suggests either a strategic pivot or a resolution that made continued litigation unnecessary.
Enforcement options may remain openIntel faces no judgment — but patent exposure persists
Intel escapes this action without a validity ruling, damages award, or injunction. However, the underlying patents — covering outer loop power control for wireless systems — remain in force. If the dismissal was without prejudice, Intel’s wireless product teams and IP counsel should treat these patents as an ongoing exposure. No fee award was entered, suggesting Intel did not pursue an exceptional-case motion in the compressed timeframe.

Official order — verbatim text
The dismissal notice invokes Rule 41(a)(1)(A)(i), the most minimal procedural exit available to a plaintiff — requiring no court approval and generating no merits ruling. The phrasing ‘voluntarily dismisses the above-captioned action’ is standard boilerplate and does not resolve the critical question of prejudice. Because no answer or summary judgment motion had been served, the unilateral right applied cleanly. Neither party obtained a substantive adjudication of infringement, validity, or claim scope, leaving both patents legally intact and the dispute commercially unresolved on the public record.
US7496376B2 & US7532865B2 — Outer Loop Power Control for Wireless Systems
US7496376B2 (application no. US11/292715) and US7532865B2 (application no. US11/293287) both protect outer loop power control technology for wireless communications systems — a mechanism that dynamically adjusts transmission power targets to maintain link quality across varying channel conditions. This class of invention is foundational to WCDMA, LTE, and 5G NR uplink power management, where maintaining signal integrity without excess power consumption is critical to network performance and device battery life.
From a competitive standpoint, these patents sit at a layer of the wireless stack that is deeply embedded in baseband processor design — exactly the domain Intel has historically addressed through its XMM modem chipset line and its acquired Infineon wireless assets. Assertion of stack-level power control patents against a chipmaker of Intel’s scale suggests TOT Power Control views these patents as having broad claim coverage potentially readable on widely-deployed commercial implementations. Any company licensing, manufacturing, or integrating LTE or NR baseband solutions should assess whether their implementations fall within the asserted claim scope.
Should your wireless product team run an FTO against US7496376B2 and US7532865B2?
If your organisation designs, manufactures, or integrates wireless chipsets, modems, or base station equipment incorporating uplink power control — particularly outer loop power control in LTE, WCDMA, or 5G NR — these two patents warrant direct attention. The fact that TOT Power Control was prepared to file against Intel, one of the best-resourced defendants in patent litigation, suggests the asserted claims are considered commercially meaningful. The absence of a validity ruling means no prior art challenge has yet succeeded against them.

What this case signals for the wireless communications IP landscape
A 63-day voluntary dismissal in a wireless power control patent suit against a tier-one chipmaker carries several forward-looking signals.
Short-duration voluntary dismissals often precede refiling or settlement
Cases dismissed under Rule 41(a)(1)(A)(i) within 90 days of filing frequently reflect either a negotiated exit or a strategic venue change rather than a substantive abandonment. Competitors and licensees in the wireless communications space should monitor TOT Power Control’s docket activity for subsequent filings against Intel or similarly situated chipmakers.
Outer loop power control patents remain a live enforcement vector
US7496376B2 and US7532865B2 are directed at fundamental wireless power management methods embedded in modern cellular chipsets. The dismissal without a validity ruling means these patents retain their presumption of validity. Any wireless chipset manufacturer — not just Intel — operating in LTE or 5G NR should assess exposure to these claims.
S.L. v Intel — key questions answered
TOT Power Control asserted two patents: US7496376B2 (application US11/292715) and US7532865B2 (application US11/293287). Both cover outer loop power control methods and devices for wireless communications systems — technology relevant to LTE and 5G NR uplink management embedded in baseband chipsets.
The public record does not disclose the reason. Voluntary dismissals under Rule 41(a)(1)(A)(i) within 63 days of filing are consistent with several scenarios: a negotiated settlement, a strategic decision to refile in a different forum, or a reassessment of case strategy. No court order, press release, or docket entry confirms the underlying reason.
The dismissal notice does not specify. Under Rule 41(a)(1)(B), a plaintiff’s first voluntary dismissal of an action is presumed without prejudice unless the notice states otherwise. If this is TOT’s first dismissal of this specific action, TOT likely retains the right to refile, though the public record does not confirm this expressly.
Outer loop power control dynamically adjusts the target signal-to-interference ratio used by inner loop power control in wireless systems, maintaining link quality across changing channel conditions. It is a standard component of WCDMA, LTE, and 5G NR uplink power management — directly relevant to Intel’s baseband modem chipsets and the wireless stack inherited from its Infineon wireless acquisition.
Likely yes, if the dismissal is treated as without prejudice under Rule 41(a)(1)(B). TOT could refile in district court, bring an ITC Section 337 action, or seek inter partes review of Intel’s designs at the PTAB. Intel and similarly situated chipmakers should not treat the dismissal as a permanent resolution of the underlying patent exposure.
