Wilcox, editors, Doing Business in China: (People’s Republic of China), volume 2, New York, N.Y.: Matthew Bender, →ISBN, page 278:On one hand, the new law may intend to enhance the application of new technologies and discourage patent trolls.

** 1992, Roger M. Milgrim, Milgrim on Trade Secrets, volume 2, Newark, N.J.: LexisNexis, →ISBN:So favorable was the Federal Circuit's treatment of patents, in fact, that reinventing, nonmanufacturing speculators who would acquire one or more patents with a view toward using their leverage to reap large damages awards, leading to the sobriquet, patent "trolls," began to emerge as plaintiffs who would often put entire industries in patent peril. Thus was born (or became more common) the "patentee" who neither invented nor practiced the subject matter of its invention, but rather, sought to profit by licensing its patent under the threat of litigation, injunctive relief and substantial damages in the propatent climate that the Federal Circuit's views had created.

[...] Being publicly branded a patent "troll" adds to the turmoil. Patent trolls are controversial not because of the destruction attributed to them, but because they strike at the heart of the complex relationship between innovation and commerce. The term has become synonymous with the unfair assertion of IP rights and extortion of damage payments.
