Japan’s Nidec files HDD patent infringement lawsuit against Seagate

TOKYO (Reuters) – Japan’s Nidec Corp said Wednesday it filed a patent infringement lawsuit against Seagate Technology LLC and its affiliates, accusing it of using Nidec hard disk drive motor designs without authorization.

The lawsuit was filed on January 18 in the United States District Court in Delaware, Nidec said in a statement.

The Japanese component maker wants the court to award him adequate compensation based on Seagate sales, a Nidec spokesperson said.

At issue were the spindle motor designs used to spin the HDD disk and the base plate the disk is in, the spokesperson said.

Seagate did not immediately respond to a request for comment.

Nidec holds approximately 85% of the global market for HDD engines, used in computers and other devices, including data center equipment. Those engines account for about one-tenth of the company’s revenue.
