According to a news after the court case over Dr. Kai-Fu Lee, from today Dr. Lee will be working for Google on the lab at China, but he is not allowed to work on the areas that he was working under Microsoft such as Search and Speech Recognition.
Both of the companies say that they have won the case. Anyway hearing that Dr. Lee is back on work is nice.
Anyway in this case there are two sides as I feel. Microsoft has a right to say that Dr. Lee should not be using what he gained at Microsoft in a competing company like Google. In the other way if he is not using those, then it is ethical for him to work in a competing company.
