Audio titan THX has filed a lawsuit against Apple, claiming that Cook and Co. infringed a patent it has for technology regarding narrow profile speakers with enhanced sound output that can be built into electronics. According to the court filing, versions of the iPhone, iPad and iMac are culprits that rely on the tech in question. Apple Insider notes that the new, slender iMacs seem to use a design similar to one described by THX, which includes channeling audio down a slim duct. Though THX is out to stop the infringement or collect damages from Cupertino, both companies could settle their differences before the affair escalates into a full-on courtroom brawl.
