AFTER EDIT TO REPLY TO A QUESTION:
I was asked for a written account of transnational comparisons of intellectual property law and its effect on innovation. Here is one.

I have to go to a conference today for work, but perhaps other participants will join in with other comments on the international legal comparison issue. I have lived in two countries (the United States and Taiwan), and I lived in Taiwan before and after it developed intellectual property law enforcement, and it is plain to me that intellectual property rights encourage innovation (as contrasted with mere copying).
