Patents are powerful weapons in a company's legal arsenal, with both defensive and offensive capabilities. Patents protect a company's innovation from potential infringers, while at the same time support the company's efforts to exploit their innovation commercially in the global marketplace. This book explores the role of patents in today's knowledge economy. We discuss how patents have become a valuable commodity and have a lucrative market of their own. However, to profit from patent monetization, this Patent market must be closely linked to the R&D market and the Product Market.
