The ‘439 patent relates to systems and methods for the storage of files on a network with improved reliability, availability and serviceability. Generally, this is accomplished by establishing a virtual file system that mirrors and links directories and files on multiple file systems.

As in Complaint:

Twin Peaks alleged that IBM had directly infringed the ‘439 patent without permission or authority from it.
Plaintiff Twin Peaks also alleged that defendant IBM has infringed the patent by its manufacture, use, sale, importation, and/or offer for sale of the following products and services: IBM Scale Out Network Attached Storage (SONAS), IBM Storwize V7000, IBM GPFS, IBM pCache, IBM Active Cloud Engine, IBM Active File Management, and IBM Automated File Management. IBM was also alleged of infringing the technology called “Panache” that uses IBM’s infringing Active File Management (AFM).

Plaintiff added that IBM’s foregoing acts of infringement were willful and deliberate. Hence Twin Peaks is entitled to recovery of past damages, at a minimum, and a reasonable royalty along with interests and costs.
