Lab Technology LLC v. Verizon Communications — Dismissed With Prejudice After 215 Days
Lab Technology LLC asserted three patents covering emergency caller location, telephone display refresh, and voice message analytics against Verizon Communications and Cellco Partnership in the Eastern District of Texas. The parties filed a joint motion to dismiss with prejudice after roughly seven months, with each side bearing its own costs — a resolution pattern consistent with a confidential settlement.
Three Telecom Patents, One Joint Dismissal, and a Confidential Exit
Filed on 3 May 2024 in the Eastern District of Texas, Lab Technology LLC brought a patent infringement action against Verizon Communications, Inc. and its wireless subsidiary Cellco Partnership d/b/a Verizon Wireless. The complaint asserted three patents — US8503973B1 (telephone display refresh), US9219982B2 (emergency caller location), and US8515032B1 (voice message usage analytics) — against Verizon’s network and device infrastructure.
On 4 December 2024, the court granted a joint motion to dismiss all of Lab Technology’s claims against Cellco Partnership with prejudice. The dismissal is with prejudice, meaning Lab Technology is permanently barred from re-asserting these same patents against the same Verizon entities in future litigation. Notably, the court’s order specifies that each party bears its own costs, expenses, and attorneys’ fees, removing any fee-shifting consequence.
The 215-day resolution and the joint, with-prejudice structure are consistent with a confidential licensing agreement or negotiated settlement — though the public record is silent on financial terms. The absence of any claim construction hearing or dispositive motion activity before dismissal suggests the parties reached commercial resolution before substantive litigation costs escalated, a pattern common among NPE-versus-carrier cases in E.D. Texas.

Dismissed with prejudice: what the joint motion means for both parties
Dismissal with prejudice extinguishes all claims permanently
A dismissal with prejudice under Federal Rule of Civil Procedure 41 operates as a final adjudication on the merits. Lab Technology cannot refile these claims against Verizon or Cellco Partnership based on the same three patents and the same alleged infringement. The joint nature of the motion signals mutual agreement — neither party was forced to this outcome by a court ruling on the merits.
Claims permanently barredLab Technology loses future leverage against Verizon on these patents
With prejudice dismissal forecloses Lab Technology from pursuing Verizon again on US8503973B1, US9219982B2, or US8515032B1 for the accused conduct. However, if a licensing agreement underlies this resolution, Lab Technology may have achieved its commercial objective. The patents themselves remain valid and enforceable against third parties not party to this case.
Patents survive; Verizon licensed or releasedVerizon secures certainty — but terms stay confidential
Verizon and Cellco Partnership obtain a clean exit with no public damages award, no injunction, and no fee-shifting against them. The with-prejudice bar prevents re-litigation. If a license was granted, Verizon gains freedom-to-operate on the patented methods. Each side bearing its own costs suggests neither party achieved a dominant litigation position before settlement.
No damages; no injunction; own costsNPE telecom patent assertions in E.D. Texas remain high-risk for carriers
This case fits a recurring pattern: NPE asserts legacy telecom patents in E.D. Texas, carrier engages counsel, and a commercial resolution follows before Markman. For other wireless carriers facing similar assertions on caller location or voice messaging patents, the speed and joint structure here suggests early negotiation reduces total dispute cost. The surviving patents may be asserted against other operators.

Official order — verbatim text
The court’s order tracks the joint motion verbatim, granting dismissal with prejudice of all Plaintiff’s claims for relief against Cellco Partnership. The phrase ‘the above-captioned case has been resolved’ in the motion — incorporated by reference into the order — strongly suggests a private agreement underpins the dismissal, though no financial terms appear on the docket. The with-prejudice designation is the operative legal consequence: it carries res judicata effect, barring any future action by Lab Technology against these Verizon entities on the same patents and accused conduct.
US8503973B1, US9219982B2 & US8515032B1 — Telecom Methods and Systems
The three patents in suit span core wireless network and device functionalities. US8503973B1 (application US13/337038) covers apparatus and methods for automatically refreshing a telephone display — relevant to notification and UI update pipelines in modern handsets. US9219982B2 (application US14/730866) claims methods and systems for obtaining emergency caller location, directly intersecting FCC-mandated E911 location infrastructure. US8515032B1 (application US13/095884) addresses systems for recording and analysing voice message usage data, touching voicemail analytics and carrier reporting functions.
Collectively, these patents represent a cross-layer attack on Verizon’s network services: device UI, emergency infrastructure, and call analytics. The breadth of subject matter across three independent patent families increases assertion credibility — invalidating one patent does not neutralise the others. For competing wireless carriers, VOIP providers, and device OEMs, the continued validity of these patents post-dismissal means the same portfolio could be directed at them. The emergency caller location patent (US9219982B2) is particularly high-risk given its intersection with mandatory regulatory compliance functions.
Should your team run an FTO against US9219982B2 and related telecom patents?
Any wireless carrier, MVNO, VOIP platform, or device manufacturer that processes emergency caller location data, manages telephone display refresh cycles, or operates voicemail analytics infrastructure should treat this patent family as an active FTO concern. Lab Technology’s willingness to sue a Tier-1 carrier like Verizon — and obtain a with-prejudice resolution — confirms enforcement intent. The patents are not abandoned or exhausted for third-party defendants.
PatSnap Eureka’s FTO Search Agent can map your product’s technical feature set against the independent claims of US8503973B1, US9219982B2, and US8515032B1, identify prior art that may support an IPR petition, and surface any continuation or related applications in Lab Technology’s portfolio. Running a structured FTO now — before receiving a demand letter — is materially cheaper than reactive litigation in E.D. Texas.

What this case signals for the telecom patent IP landscape
This dismissal illustrates the economics of NPE assertions against Tier-1 carriers in E.D. Texas: fast resolution, confidential terms, and preserved patent validity for future enforcement.
Legacy telecom patents retain licensing leverage even without litigation wins
Lab Technology’s three patents — covering caller location, display refresh, and voice analytics — date from application filings spanning 2011–2015. Despite their age, the with-prejudice joint dismissal suggests Verizon saw enough infringement risk to negotiate rather than litigate to judgment. Carriers should audit exposure to similarly structured legacy patent portfolios.
E.D. Texas remains the venue of choice for NPE telecom assertions
Filing in the Eastern District of Texas is a deliberate strategic signal. The district’s familiarity with patent cases, plaintiff-friendly procedural history, and docket speed create settlement pressure on defendants early. Wireless operators without a proactive E.D. Texas monitoring strategy face repeated exposure to NPE filings targeting network and device features.
Lab v Verizon — key questions answered
Lab Technology LLC asserted three patents: US8503973B1 (automatic telephone display refresh), US9219982B2 (emergency caller location method and system), and US8515032B1 (voice message usage recording and analysis). All three were filed in the Eastern District of Texas on 3 May 2024.
The parties filed a joint motion representing that the case had been ‘resolved,’ and the court granted dismissal of all Plaintiff’s claims with prejudice on 4 December 2024. The public record does not disclose financial terms, but the joint structure and with-prejudice designation are consistent with a confidential licensing or settlement agreement.
No. The with-prejudice dismissal bars Lab Technology from re-asserting these three patents against Verizon Communications and Cellco Partnership for the same accused conduct. The patents remain valid and enforceable against third parties — other wireless carriers, MVNOs, VOIP providers, or device OEMs — who were not party to this case.
The court’s order directs each party to bear its own costs, expenses, and attorneys’ fees, meaning no fee-shifting award was made under 35 U.S.C. § 285. This symmetric outcome suggests neither party held a dominant litigation position at the time of settlement and that no finding of exceptional case was warranted or sought.
US9219982B2 claims methods and systems for obtaining emergency caller location data — technology embedded in virtually all US wireless networks under FCC E911 obligations. This regulatory overlap increases assertion breadth, as any carrier or VOIP provider subject to E911 requirements potentially practices the claimed methods. The patent’s continued validity post-dismissal makes it a notable FTO concern for the industry.
