Tellabs sues Fujitsu claiming patent infringement

And the patent wars continue …

Naperville. Ill.-based telecom equipment maker Tellabs Inc. is seeking monetary damages and an injunction against Fujitsu Ltd. and its Fujitsu Network Communications Inc., saying the Japanese company infringed on its patents involving reconfigurable optical all/drop multiplexing systems (ROADM) and components that Fujitsu markets as part of its FLASHWAVE product line.

“This is the technology in the Tellabs 7100, and sales for this has grown four times this year, compared to last year already,” said Tellabs spokesman George Stenitzer. “This is really a hot product.”

A Fujitsu spokesman was unavailable for comment.

Tellabs filed the lawsuit in the U.S. District Court for the Northern District of Illinois.
