Cisco has prevailed in a patent suit filed against it by Storage Technology.

Storage Technology, also known as StorageTek, had filed suit seeking $3 billion in damages. The suit was filed in 1999. The patent involved faster processing of data entering firewalls.

Matt Powers, the lawyer defending Cisco told news media outlets on Wednesday that a jury in the US District Court for the Northern District of California had ruled in Cisco’s favor.

StorageTek said it was considering its options following the verdict.
