Abstract

This research explores how option-implied information predicts quality of patents. Using several measures of option-implied information, we find that only the option to stock volume (O/S) ratio positively and significantly predicts quality of patents around patent grant announcements. The findings are not entirely driven by information from the stock market and the probability of informed trading. Further investigations show that the predictability of O/S on patent quality is stronger when market sentiment is high, firms have a higher short-sale cost, and the quality of patents is relatively high.
