Cutting Through the Patent Thicket

xzvf writes wrote to mention a BusinessWeek article positing that the overgrowth of patents is harmful to innovation. From the article: "The first problem with patents is that the entire process takes too long: three years on average, often as long as five, and getting longer all the time. So when a venture capitalist invests in a company, its IP 'dowry' remains, at best, provisional. How much would you pay for a company when its assets are hidden from view?"
