Apple has sued Samsung over the latter’s Galaxy series of phones and tablets, claiming that the products infringe on Apple’s intellectual property. The Wall Street Journal reports that the suit names products such as the Galaxy S 4G, Epic 4G, Nexus S, and Galaxy Tab as copying the look and feel of Apple’s iPhone and iPad. “Rather than innovate and develop its own technology and a unique Samsung style for its smart phone products and computer tablets, Samsung chose to copy Apple’s technology, user interface and innovative style in these infringing products,” the lawsuit said. Notably, Apple purchases flash memory and other components from Samsung, and the South Korean company is the manufacturer of the A4 chip found in the iPhone 4, as well as the new A5 chip that powers the iPad 2.
