Then, drawing on the signaling role of patents highlighted by the … patentability standards at PTOs (Patent and Trademark Offices awarding so-called bad patents), not only "false innovators" have the … chance of being granted patents but also, and more interestingly, "true innovators" are forced to patent more intensively …

Biographical information on a sample of renowned U.S. inventors is combined with information on the patents they … enforce tradable assets in new technological knowledge. By facilitating access to such markets in technology, patents enhanced … their technological creativity, and their response to such incentives increased overall technological progress. For this …

We study the prevalence and traits of global collaborative patents for U.S. public companies, where the inventor team … is located both within and outside of the United States. Collaborative patents are frequently observed when a corporation … is weak. We also connect collaborative patents to the ethnic composition of the firm's U.S. inventors and cross …

This paper analyzes the optimal protection strategy for an innovator of a complex innovation who faces the risk of … imitation by a competitor. We suppose that the innovation can be continuously fragmented into sub-innovations. We characterize … fraction of the innovation once.
