Trade secrets--stealing them, protecting them, enforcing them--are increasingly big business. To understand why, consider any information you know about your job that you're supposed to keep confidential. That information may qualify as a trade secret. Trade secrets thus concern everyone from the engineer who invents a better mousetrap to the marketer who knows pre-release prices, from the CEO who drafts the company's five-year plan to the HR rep who manages the organizational chart, and so on.
