I recently finished Counterfeiting Exposed, Protecting Your Brand and Customers. Unlike Knockoff, The Deadly Trade in Counterfeit Goods, which is a readable introduction to the subject, Counterfeiting Exposed is more of a handbook for businesses trying to understand how counterfeiting works, the damage it does to a brand, and how to stop counterfeiters.
Counterfeiting Exposed includes a lot of useful information, including the names of service providers and tables showing the return on investment that a company can realistically achieve with an anti-counterfeiting program.
I had a couple of quibbles with the editing, though. References to the Virgin Group's "crossover from airlines to music" (page 33) might come as a surprise to anyone who followed the UK punk scene in its heyday. The authors also quote conflicting figures for Proctor & Gamble's counterfeiting losses, at one point saying P&G was losing $300 million a year in China, in another saying the company was losing $150 million a year, overall. And many of the claimed counterfeiting losses are stated as a matter of fact, without any supporting data, which detracts from their credibility.
These criticisms aside, Counterfeiting Exposed covers a lot of ground and is worth a look if you're planning a program to protect your brand.
