Schaumburg, Illinois, April 15, 2025 – Lemko Corporation, a pioneer in Network Functions Virtualization
(NFV), is pleased to announce that the DISTRICT COURT FOR THE NORTHEN DISTRICT OF TEXAS has denied
Microsoft’s motion to dismiss Lemko’s direct and indirect patent infringement claims. Lemko filed the
lawsuit against Microsoft and Affirmed Networks on February 14th , 2022 (Case No. 3:33-cv-00363-L-BT).
The lawsuit alleges that Microsoft is unlawfully utilizing Lemko’s patented mobile network innovations,
which are designed to significantly reduce both deployment and operational costs of mobile broadband
networks.

Lemko’s groundbreaking approach involves virtualizing network functions through software deployed on
off-the-shelf servers located at the network’s edge, near the radio access network. This methodology not
only simplifies the deployment of mobile cores but also reduces operational expenses by minimizing
backhaul resource requirements. Notably, Lemko introduced its “Distributed Mobile Architecture”
software seven years prior to the mobile industry’s acknowledgment of the benefits of NFV in the ETSI
white paper published in October 2012. Since then, the industry has widely adopted NFV, transitioning
network functions to software-based solutions operating on standard servers.
Microsoft acquired Affirmed Networks in March of 2022. The goal of the acquisition was integrate
Affirmed Networks virtualized packet into Microsoft’s Azure Operator Nexus platform.
Lemko is represented by Paul Andre, Lisa Kobialka, James Hannah, and Aaron Frankel of Kramer Levin
Naftalis and Frankel. The firm’s Intellectual Property team is experienced in asserting and defending IP-
related claims across various U.S. courts and before the U.S. Patent and Trademark Office.
