Patents and Their Impact on Consumer Product Prices

This technical report investigates the relationship between patent protection and the pricing of consumer products. It utilizes an original dataset linking consumer products to their respective patents, analyzing how the loss of patent protection affects product prices. The authors, Gaétan de Rassenfosse and Ling Zhou, find that when patent protection is lost, product prices decrease by 8-10%. This decline is more significant for patents deemed more important and in competitive markets. The study also examines the timing of price changes, noting that prices tend to drop approximately one year before patent expiry, suggesting strategic pricing behavior by firms. The report contributes to the ongoing discussion regarding the effectiveness of the patent system in fostering innovation and provides empirical evidence that supports the notion that patent protection allows for higher price premiums. The findings are relevant for understanding the economic implications of intellectual property rights and their role in market dynamics.
