DOWNLOAD EBOOKWhy Has America Stopped Inventing? takes a close look at why America’s 200 year experiment with patents appears to be failing, and why America has all but stopped inventing. It explains why our over-legislated patent system has snuffed out any incentive to invent desperately needed technologies, such as new forms of clean energy. Why Has America Stopped Inventing? shows how this happened by comparing the experiences of America’s most successful 19th century inventors with those of today.
