Claiming "monetary damage and irreparable harm" THX sued Apple Inc. for stealing speaker technology used in Apple devices, including iPhones, iPads and iMacs.

Specifically, the suit claims that Apple violates a patent, held by THX since 2008, that boosts sound output through a speaker attached to a computer or flat-screen TVs. The audio reproduction company founded by George Lucas, is asking the court to stop the infringement and reasonable compensation for lost profit.
