Exploring the nonlinear effects of patent H index, patent citations, and essential technological strength on corporate performance by using artificial neural network

This study utilizes the artificial neural network to explore the nonlinear relationships between patent performance and the corporate performance of the pharmaceutical companies. Patent performance measured from patent H index, patent citations, and essential technological strength (ETS). The result shows that patent H index, patent citations, and ETS has the nonlinear effect on the corporate performance of the pharmaceutical companies.

► We examine the nonlinear effects of patent indicators on corporate performance.
► Patent indicators measured from patent H index, patent citations, and ETS.
► Sales as the proxy variable of corporate performance.
► Patent indicators have the nonlinear effect on the corporate performance.
