Lawsuit Against McAfee Alleging Patent Infringement and False Marking: DeepNines Wins Interference against McAfee and is Granted Patent

DALLAS (August 16, 2006) Deep Nines, Inc., a network security solutions provider, today filed a lawsuit against McAfee, Inc., (Nyse: MFE) for infringement and false marking of its recently issued U.S. patent on a key network security technology.

The alleged infringement and false marking concerns U.S. patent number 7,058,976, issued to DeepNines on June 6, 2006, which involves combining a firewall and a signature-based intrusion detection/prevention solution (IDS/IPS) on a single, inline device that takes action in real-time.

DeepNines filed and won an interference against McAfee regarding this patent in March 2005, but McAfee has continued to mark and sell products that claim this patent as their own. DeepNines is asking the court for damages and a permanent injunction to prevent McAfee from marketing and selling the infringing products. DeepNines is being represented by the law firm Fish & Richardson P.C.

"DeepNines focus has always been on developing products that solve fundamental customer pain points. Customers are demanding integrated solutions because they are the most secure, efficient and easy to manage, and we are thrilled to hold the patent for innovating a solution that meets these requirements", said Sue Dark, founder of DeepNines.

"We intend to protect our intellectual property, just as we respect the intellectual property rights of others", said Dan Jackson, president of DeepNines. "Although DeepNines continuously monitors the products of its competitors, at this point, our focus remains on McAfee for both infringing our patent and falsely marking its products with a patent that is invalid and purports to claim the same invention covered by our patent."

DeepNines uses this patented technology in its unified threat management (UTM) and intrusion prevention (IPS) devices, the Security Edge Platform (SEP). The SEP was built from the ground up to seamlessly integrate firewall, behavior and signature-based intrusion prevention, anti-virus and traffic management into a single device. It inspects every inbound and outbound packet to protect the entire network from attacks and to increase bandwidth utilization by filtering out unwanted traffic.
