Samsung Electronics is suing Apple, claiming its rival violated its patent rights, days after Apple accused Samsung of "slavishly" copying designs of its iPad and iPhone. The patent lawsuits, filed in South Korea, Japan and Germany, involve infringement of up to five patents, Samsung said in a statement. Apple filed a lawsuit against Samsung last Friday for violating its patents. It is the latest patent dispute in an increasingly competitive industry. Apple being made to taste its own medicine I guess, and as they noted in the article that both companies have significant stake/need in/of each other it will be interesting to see how things go from here.
