Patent citations and patent importance
This article reviews the empirical evidence on the use of patent citations as a proxy for invention importance. It distinguishes between technical merit, private economic value, and social value, and surveys validation studies using expert ratings, market data, renewal records, and compensation reports. The findings confirm that while the count of citations is positively associated with various dimensions of value, it remains a noisy indicator -- correlated but far from definitive.
