The Verdict & Legal Analysis
Outcome
On October 27, 2025, the Southern District of Florida ordered this action dismissed with prejudice pursuant to the plaintiff’s Notice of Voluntary Dismissal filed under FED. R. CIV. P. 41(a)(1)(A)(i). The court’s order specified that each party shall bear its own attorneys’ fees and costs.
Legal Significance
The dismissal with prejudice means Lab Technology LLC is permanently barred from re-filing the same infringement claims against ETA Phi Systems on US9,219,982 B2. This contributes to the observable pattern of early voluntary dismissals in telecommunications interface patent cases. For practitioners tracking US9,219,982 B2, this dismissal with prejudice does not adjudicate the patent’s validity or enforceability — meaning the patent remains potentially assertable against other defendants.
