Back in January we reported that NVE filed a patent infringement lawsuit against Everspin Technologies in the US. NVE claims that Everspin infringes three NVE MRAM patents. Today Everspin responded with a suit of their own, claiming that NVE infringed on two US patents related to GMR-based isolators, sensors, encoders and memory.
