Ask Slashdot: When Is Patent License Trading Not Trolling?

LeadSongDog writes "A piece in yesterday's Forbes offers arguments on why not all 'Non-Practicing Entities' are 'Patent Trolls.' Comments here on such businesses are often critical. Is there a right way to trade in patents for profit without abusing the process?" From the article: "The Founders’ decision to foster non-practicing entities and patent licensing proved crucial to America’s rapid technological progress and economic growth. Patent records from the nineteenth century reveal that more than two-thirds of all the great inventors of the Industrial Revolution, including Thomas Edison and Elias Howe, were non-practicing entities who focused on invention and licensed some or all of their patents to others to develop into new products."
