On January 28, Avalanche Technology filed a lawsuit in the United States District Court for the District of Delaware, against Everspin Technologies saying that Everspin's STT-MRAM technology infringes upon Avalanche's patents.

Avalanche says that there are 4 patents that Everspin infringes upon : U.S. Patents 9,318,179, 9,419,210, 11,678,586, and 10,490,737. The Lawsuit requests customary remedies for patent infringement and the ITC Complaint requests that the U.S. ITC Investigation commence an investigation.
Everspin said in a statement that it has meritorious arguments against Avalanche’s claims and intends to vigorously defend itself against such claims. In addition, Everspin says that these claims do not implicate the Company’s Toggle MRAM, or sensor devices.
