To achieve target of maximal profit and sustainable development, enterprises not only from the patent to understand the current competitive position in the industry, but also implement diversify strategies to maintain the existing business’s growth. The purpose of this study is to analyze and explore the determinants of patent diversification in U.S. Biological, Pharmaceutical, and Medical Instrument Industries. The observation time is from 2003 to 2008 and the data set include 216 Biological observations, 296 Pharmaceutical observations and 182 Medical Instrument observations in the United States Patent and Trademark Office (USPTO) database. We used the multinomial logistic regression to extract the determining factors of patent citations. This study includes 7 factors of affecting patent diversification: R&D intensity, capital expenditures, firm sizes, firm risk, firm age, diversification, and patent positions. We find that firm age and patent positions are significant in the Biological industry. Firm sizes and diversification are significant in the Pharmaceutical industry. Capital expenditures, firm sizes, diversification, and patent positions are significant in the Medical Instrument industry. Firms can use capital expenditures, firm sizes, firm age, diversification and patent positions to improve patent diversification.
