Lundin lawsuit dropped
MARQUETTE – A California man who sued the Lundin Mining Corp. in U.S. District Court for alleged patent infringement related to the Eagle Mine’s use of technology in the mine’s water treatment plant has dropped his lawsuit.
Debasish Mukhopadhyay, of Palo Alto, Calif., claimed his U.S. “Hero” patented method for high efficiency reverse osmosis operation was infringed upon by Veolia Water Solutions and Technologies North America in its Opus technology.
In October 2011, then mine owner Kennecott Eagle Minerals Co. -wholly owned by Rio Tinto- awarded Veolia a contract for an Opus wastewater treatment plant at the Eagle Mine.
The lawsuit was filed in the U.S. District Court in California’s Northern District in San Francisco. On Wednesday, a notice was filed with the federal court indicating Mukhopadhyay had voluntarily withdrawn the lawsuit. Court documents did not indicate why the suit was dismissed.
Lundin officials said they had received confirmation of the new status of the case.
“We’re pleased with this change of events and we’re focusing our energy on completing Eagle on time and on budget,” said Lundin spokesman Dan Blondeau.
Mukhopadhyay is a “well-recognized inventor of unique industrial water purification technologies for the electricity generation, chemical, petrochemical, pharmaceutical, microelectronics and other industries,” the complaint stated.
During the past 15 years, as the owner of the Hero patents, Mukhopadhyay has licensed his water purification technologies to industry leaders, including General Electric, Intel and Aquatech.
