Data storage provider Western Digital ( WDC ) must pay $315.7 million in damages for violating a patent owner's rights in data security technology, a jury in California federal court said on Friday.

The jury determined that several Western Digital ( WDC ) self-encrypting hard drive products infringe a SPEX Technologies patent covering data encryption innovations, a SPEX attorney said in an email.

San Jose, California-based SPEX sued Western Digital ( WDC ) in 2016. SPEX said it bought the patent at issue from Spyrus, a cryptography company that developed the technology for encrypting sensitive communications.

The lawsuit said Western Digital ( WDC ) data storage devices including its Ultrastar, My Book and My Passport products infringed the patent. Western Digital ( WDC ) denied the allegations.

In July, a different jury in the same Santa Ana, California, court said Western Digital ( WDC ) owed more than $262 million to another company for infringing patents related to increasing hard drive storage capacity.
