Ramey LLP announced that its client, PACSEC3, LLC, has filed a patent infringement lawsuit against LUMEN TECHNOLOGIES, INC. The lawsuit was officially lodged on June 30, 2025, in the Eastern District of Texas, Marshall Division.

The legal action centers on the infringement of U.S. Patent No. 7,523,497. This crucial patent protects a “PACKET FLOODING DEFENSE SYSTEM.” In today's digital age, where network availability is paramount, packet flooding attacks (a common form of Denial-of-Service or DDoS attack) pose a significant threat. These attacks aim to overwhelm network resources with a flood of useless data, thereby disrupting legitimate traffic and making services unavailable. The '497 patent describes a sophisticated system for mitigating such attacks, often involving distributed defense mechanisms to identify and reduce the rate of malicious data.

The primary goal of PACSEC3, LLC's legal action is to address the patent infringement and to vigorously protect their intellectual property rights from LUMEN TECHNOLOGIES, INC. By filing this lawsuit, PACSEC3, LLC aims to seek appropriate relief and ensure the full enforcement of its patent rights through the legal system.

Ramey LLP is diligently representing PACSEC3, LLC in this significant intellectual property matter. This lawsuit underscores the critical importance of protecting innovations that safeguard digital infrastructure from relentless cyber threats, ensuring the stability and availability of online services for users worldwide.
