In today's ultra-competitive global economy, intangibles are increasingly taking centre stage in firms' business strategies and investors' valuations. Physical and financial assets are becoming commodities, yielding at best a competitive return on investment. In their place, intangible assets such as patents, brands, unique business processes, breakthrough scientific discoveries and strategic alliances are what firms are using to create dominant market positions, control risk, generate abnormal profits, and achieve growth and wealth.

This reader provides that understanding by bringing together the best research and advocacy on intangibles.
