Tuesday, San Francisco, California-based Riverbed Technology Inc. (RVBD), a provider of solutions for wide-area distributed computing, issued its response to a patent infringement lawsuit filed by Quantum Corp. (QTM) against the company. Riverbed said that it has no factual or other basis to believe that it infringes the patents of any third party, including Quantum. Earlier today, Quantum, a storage company, said it has filed a patent infringement lawsuit in the U.S. District Court in the Northern District of California against Riverbed. In its lawsuit, Quantum alleged that Riverbed has infringed, and continues to infringe, a Quantum patent by selling products that employ a method of data de-duplication covered by this patent. Quantum said the patent at issue was granted in November 1999 and is a pioneering patent in data de-duplication.Data de-duplication technology eliminates redundant data for storage on disk and transmission via networks. It increases effective disk capacity over that of conventional disk, thus enabling users to retain data on fast recovery disk for months instead of days. It also reduces the bandwidth needed to transmit such data between sites.San Jose, California-based Quantum said over the past year it has concluded confidential license agreements with other companies that encompass this pioneering patent. Shawn Hall, vice president and general counsel of Quantum, said efforts to resolve the issue were unsuccessful and the company had no choice, but move ahead with legal action.RVBD closed Tuesday's regular trading session at $47.18, up 53 cents or 1.14%. However, in the after-hours, the shares lost $1.18 or 2.50%. QTM ended Tuesday's regular trading session at $3.80, up 8 cents or 2.15%. However, in the after-hours, the shares lost 3 cents or 1.03%.
