Lab Technology LLC v. Here North America: Dismissed With Prejudice After 127 Days
Lab Technology LLC filed suit against Here North America, LLC in the Northern District of Illinois asserting two patents covering telephone display refresh and announcement system technologies. The case ended in a voluntary dismissal with prejudice — the most conclusive self-termination available to a plaintiff — just 127 days after filing, before the defendant had answered.
Early dismissal with prejudice ends two-patent assertion before answer
Lab Technology LLC filed this patent infringement action on 17 April 2025 in the Northern District of Illinois before Judge Jeffrey I. Cummings. The complaint asserted two patents — US8498388B1, directed to an apparatus and method for automatically refreshing a display of a telephone, and US9219982B2, covering a method and system for announcement — against Here North America, LLC, a provider of mapping and location intelligence services.
The case closed on 22 August 2025 via a voluntary notice of dismissal filed under Federal Rule of Civil Procedure 41(a)(1)(A)(i). Critically, the dismissal was expressly stated to be with prejudice. Because Here North America had not yet answered the complaint or moved for summary judgment at the time of filing, the plaintiff was procedurally entitled to dismiss unilaterally. The with-prejudice designation, however, was a deliberate election beyond that procedural baseline.
At 127 days, the resolution is notably swift and suggests the parties reached an accommodation — or that plaintiff concluded continued litigation was commercially unviable — before any substantive court engagement. The public record does not disclose whether any licensing agreement or payment was exchanged. The fee arrangement, each party bearing its own costs, is consistent with either a negotiated exit or a straightforward walk-away, though the with-prejudice designation prevents any inference that plaintiff preserved optionality.

Voluntarily dismissed with prejudice: what the filing means for both parties
Rule 41(a)(1)(A)(i): unilateral dismissal before answer
Federal Rule of Civil Procedure 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 a motion for summary judgment. Here North America had done neither, so Lab Technology could act unilaterally. The plaintiff went further, however, expressly designating the dismissal as with prejudice — a self-imposed bar that required no judicial approval.
With prejudice — plaintiff’s own electionWith prejudice: no second bite at the apple
A dismissal with prejudice operates as a final adjudication on the merits, permanently barring the plaintiff from reasserting the same claims against the same defendant. The public record does not specify whether a settlement was reached. What is clear is that Lab Technology has foreclosed any future infringement action against Here North America on US8498388B1 and US9219982B2. This is a stronger form of closure than a without-prejudice exit, which would preserve the option to refile.
Claims permanently extinguishedHere North America exits without admitting liability
Here North America never filed an answer, meaning it made no formal admissions or denials regarding infringement. The dismissal removes the immediate litigation threat and, given the with-prejudice designation, eliminates the risk of a re-filed action on these specific patents. Each party bearing its own costs signals Here North America incurred defence costs without any recovery mechanism, which is typical in early-stage voluntary exits regardless of underlying commercial arrangements.
No liability admitted or adjudicatedPatents remain in force but enforcement against this defendant is closed
US8498388B1 and US9219982B2 remain valid and enforceable patents. The dismissal with prejudice applies only to Lab Technology’s claims against Here North America — it does not affect the patents’ enforceability against third parties. Other companies operating in telephone display management or announcement system technologies should note that the patents are still in the portfolio and could be asserted in future actions against different defendants.

Official order — verbatim text
The dismissal notice invokes Rule 41(a)(1)(A)(i) and expressly designates the termination as with prejudice — an election that converts a procedurally simple unilateral notice into a permanent bar on these claims. The fee-splitting term (‘each party shall bear its own costs’) is neutral and consistent with both a negotiated settlement and an unconditional walk-away. No merits adjudication occurred, so the verdict record does not speak to infringement, validity, or claim scope of either asserted patent.
US8498388B1 & US9219982B2 — telephone display refresh and announcement systems
US8498388B1, filed under application number US13/401844, protects an apparatus and method for automatically refreshing a display of a telephone — a functional invention directed at how telephony interfaces update displayed information dynamically. US9219982B2, filed under application number US14/730866, covers a method and system for announcement, addressing how automated announcement content is generated and delivered. Both patents sit within the communications and telephony systems domain and carry granted status in the US.
From a strategic standpoint, telephone display management and announcement systems intersect with a broad range of modern communications, mapping, navigation, and voice assistant platforms. Here North America’s location intelligence services would plausibly incorporate interface refresh and notification delivery features, explaining the assertion logic. The patents’ continued validity means companies building or acquiring products with dynamic display or automated announcement functionality should assess landscape exposure, particularly given that no claim scope was adjudicated or disclaimed in this proceeding.
Should your product team run an FTO against US8498388B1 and US9219982B2?
Any product team developing telephony display management features, automated notification systems, or announcement delivery mechanisms operating on or interacting with telephone interfaces should treat these two patents as active FTO considerations. The dismissal of this specific case does not signal weakness — no invalidity argument was ever tested. Mapping, navigation, communications, and enterprise voice platform developers are within the plausible risk perimeter.

What this case signals for telephone display and announcement system IP
A swift with-prejudice exit before answer raises questions about assertion strategy and patent strength in this technology corridor.
Pre-answer dismissal with prejudice is a definitive, not provisional, outcome
Practitioners should note that unlike a without-prejudice voluntary dismissal, this filing permanently closes the door on these claims against Here North America. Companies in mapping, navigation, or telephony sectors that have received demand letters from Lab Technology on these patents should assess whether a similar resolution is achievable and on what terms.
Speed of resolution suggests no claim construction or discovery pressure
At 127 days with no answer filed, the case never reached claim construction scheduling or early discovery. The absence of any substantive litigation record means there is no public file history to inform claim scope debates. Competitors and potential targets should not read prior-art or claim-scope concessions into this outcome — none were made on the record.
Lab v Here — key questions answered
It means Lab Technology LLC unilaterally filed a notice of dismissal before Here North America had answered, and expressly designated it as with prejudice. This permanently bars Lab Technology from reasserting infringement claims on US8498388B1 and US9219982B2 against Here North America. No court order was required because the defendant had not yet answered.
Yes. A with-prejudice dismissal is defendant-specific. The patents remain granted and enforceable against any party other than Here North America. Lab Technology LLC or any subsequent assignee retains the right to assert these patents in separate actions against different defendants. The dismissal extinguished only the claims in case 1:25-cv-04239.
The public record does not confirm a settlement. The dismissal notice states each party bears its own costs, which is consistent with both a negotiated exit and an unconditional withdrawal. No settlement agreement has been filed on the public docket. The with-prejudice designation may reflect a licensing resolution, but this is not confirmed by the available record.
US8498388B1 covers an apparatus and method for automatically refreshing a display of a telephone — addressing dynamic interface updates on telephony devices. US9219982B2 covers a method and system for announcement — addressing automated announcement generation and delivery. Both sit in the telephony and communications systems technology domain.
The case closed before Here North America filed an answer, meaning no claim construction, discovery, or dispositive motion practice occurred. A 127-day pre-answer resolution typically suggests the parties reached a commercial accommodation, or the plaintiff assessed litigation risk and elected to exit. The public record does not disclose the specific reason, and no merits determination was made by the court.
