Quantum, a San Jose, Calif.-based medical archive company, has filed a patent infringement lawsuit in the U.S. District Court in the Northern District of California against Riverbed Technology.

According to the suit, Riverbed has infringed and continues to infringe upon Quantum patent, U.S. Patent 5,990,810, by selling products that employ a method of data de-duplication covered by the patent. The Quantum patent at issue was granted in November 1999.

Quantum’s data de-duplication technology eliminates redundant data for storage on disk and transmission via networks.

“Over the last eight months, we have worked to engage Riverbed in an effort to resolve this issue directly,” said Shawn Hall, vice president and general counsel of Quantum. “Unfortunately, this effort has been unsuccessful, and we felt we had no choice but to initiate legal action to protect our intellectual property in data de-duplication.”
