In this third episode we explore how attitudes in Shenzhen about patents and intellectual property differ to those in the West. In particular, we look at how the evolution of “ shanzhai” - or copycat manufacturing - has created an ecosystem that could transform traditional models of business, distribution and innovation. Although, technically, any knock-off goods can be called shanzhai, the word's meaning has recently shifted to refer to electronic goods, and episode three delves behind the scenes of this business culture.
