The 10 Ugliest Legal Disputes Of 2011


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.
