NVE filed a patent infringement lawsuit against Everspin Technologies in the US. NVE claims that Everspin infringes three NVE MRAM patents. NVE seeks an injunction for Everspin to cease using NVE?s patented technology and provide compensation for damages caused by the infringement.
Everspin was spun-off Freescale, which was spun-off from Motorola, which was an NVE licensee. Back in 2006, when Freescale announced the first MRAM products, NVE tried to negotiate an agreement with them, it seems that after 5 and a half years the company decided to resort to litigation after all. Here's what Daniel Baker (NVE's CEO) said back then: "Based on a preliminary analysis, we believe Freescale's MRAM comes within the scope of claims in a number of NVE patents. We hope to negotiate a mutually beneficial agreement with Freescale to give them access to NVE intellectual property without having to resort to litigation"
