A worker fixes an entrance sign at the Samsung booth before the IFA consumer electronics fair in Berlin in this August 28, 2012 file photo. Samsung Electronics is the world's biggest technology firm by revenue, making the group a must-visit case study for a stream of Chinese firms seeking to tap the secrets of Korean success. But, in the wake of the damaging U.S. patent ruling in August, 2012, the Korean group was fined more than $1 billion after a jury found it had copied key features of Apple Inc's iPhone - the group's top-down command structure and decision-making process are blamed for stifling creativity.
