NVE Corp., an Eden Prairie company that makes magnetic nanotechnology products for computer memory, filed a lawsuit Tuesday in federal court charging a competitor with infringing on three of its patents.
NVE alleged that Everspin Technologies Inc. of Chandler, Ariz., used three of NVE’s patents to make what are called Magnetoresistive Random Access Memory products, according to the suit filed in U.S. District Court in Minnesota.
Executives for Everspin were traveling and could not be reached for comment Tuesday, a company spokeswoman said.
In conventional computer Random Access Memory, computer memory is stored using electrical charges in a semiconductor, such as silicon.
But Magnetoresistive Random Access Memory uses spintronics, a nanotechnology that depends upon magnetic forces to harness spinning electrons. The spinning electrons hold data, saving battery power and eliminating long software boot-ups because the memory is always on.
“We have invested significant resources in research and development over the years, and we are defending our rights to protect these investments,” NVE Chief Executive Daniel Baker said in a statement Tuesday.
NVE filed the patents in 2001 and 2002, according to the lawsuit.
In its lawsuit, NVE asked the court to enjoin Everspin from making and selling products that infringe upon the patents.
NVE also asked the court to make Everspin pay treble damages for willful infringement. NVE did not specify a damage amount,
