The company is recorded as a defendant in one tracked case and has no plaintiff cases, indicating its posture as an operating company defending against infringement allegations.

While the specific case data lists Western Digital as a defendant against Viasat, external context reveals a more intricate litigation landscape.

The company has also been involved in other patent disputes as a defendant, such as a case with SPEX Technologies regarding data encryption patents, where an initial $553 million damages award was significantly reduced to $1 in post-trial motions in the Central District of California. Another case against MR Technologies GmbH in the Central District of California, involving HDD technology, was dismissed with prejudice, suggesting a private settlement.
