Yep.
As of Friday, April 15, 2011, Apple has officially filed a lawsuit against Samsung, claiming that Samsung copied hardware elements and user interface. Their infringement claim is phrased as follows:
“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.”
Seeing as this is breaking news, we’ll be updating you all as to how things are progressing.
