4. Apple Sues Samsung For Patent Infringement
Apple sued Samsung in the U.S. in April for patent infringement, claiming that Samsung's Galaxy smartphones and tablets bear a suspicious resemblance to the Apple iPhone and iPad.
So far it's been advantage Samsung: Earlier this month a U.S. District Court judge in California ruled that Samsung could continue selling the Galaxy products in the U.S. pending a trial in the case, now set for July 2012.
Samsung has long manufactured the ARM-based A6 system-on-a-chip used in the Apple iPad, and a subtext for the Apple-Samsung dispute are reports that Apple is thinking of moving its chip production away from Samsung to another fabrication partner, Taiwan Semiconductor Manufacturing Co.
