Audi, BMW, Others Beat Power Inverter Patent Suit at ITC

In a final initial determination made public on September 9, 2022, the International Trade Commission (ITC) determined that power inverters imported by a group of automotive companies, including Finnegan client BMW of North America, do not infringe the two patents asserted by Arigna Technology Ltd. Arigna had sought a ban on power inverters and converters and automobiles that contained them. The commission also found that previous publications rendered some of the patents’ claims unenforceable and that the disputed imports do not meet claimed limitations in the patents, such as the presence of an electric circuit known as a “current amplifier.”

Finnegan partner Lionel Lavenue said, “We are pleased with the ALJ’s ruling and appreciate the time and consideration that the ALJ, staff, and commission have given to BMW’s positions.”
