The Boston Globe has an article on the makers of Titleist Golf Balls fight against counterfeits in China. 

From the Boston Globe:

 Jason Yao lives a dangerous life for a guy in the golf business.

He gets death threats. He raids factories and markets. He shakes down informants and hangs out with private investigators. He has 10 aliases.

China is the focus of the worldwide war against counterfeit golf products, and Yao is on the front lines. His employer, Acushnet, located 7,000 miles away in Fairhaven, Mass., makes the world’s most popular - and most copied - golf ball, the Titleist Pro V1, along with clubs, accessories, and shoes that counterfeiters mimic for sales around the globe.
