Fujitsu Network Communications announced the resolution of its long-running litigation against Tellabs, Inc. and its subsidiaries.?
The case, which has spanned more than half a decade, started in 2008 when Fujitsu sued Tellabs for infringing four of Fujitsu's patents, including a patent related to optical amplifiers used in optic fibre transmission networks.
The litigation, however, was whittled down to a jury trial, which limited to whether Fujitsu breached an International Telecommunications Union (ITU) optical network standard setting obligation in asserting a patent against Tellabs without offering a reasonable and nondiscriminatory terms (RAND) licence. In the end, the jury found Fujitsu breached its RAND obligations, but the presiding judge delayed ruling on a show cause order for Fujitsu so the two companies could pursue settlement.
