Quite an interesting chart. Reuters is underated as media organisations go. This chart doesn't show companies that have outright banned other products from being sold in other countries. That's the ultimate dirty fighting, and they haven't mentioned counter-lawsuits. That said, the corporate world is one pretty little court case after another.
Also, the chart doesn't show companies that have created counter-lawsuits in retaliation e.g. Apple sued HTC so HTC decided to counter-sue Apple, Apple bringing Samsung to court then Samsung countering the case with another one. Many seem to be located and pointing at Apple which doesn't leave much to the imagination.
