I have tried to assess what consequences the strategy has had for Philips’ competitors and the competition on electric shaver markets all over the world. I find it interesting that Philips despite repetitious expensive losses has continued to initiate litigations and take other legal actions, which is why I have also tried to determine what Philips has gaine...
