A Dynamic Stochastic Analysis of International Patent Application and Renewal Processes

Deng, Yi - Southern Methodist University, Department of Economics - 2005

This paper formulates a dynamic stochastic model to examine the joint patent application and renewal behavior under an international patent protection regime. This framework makes it possible to utilize both the cross-sectional (multi- country filing) and the time-series (patent renewal)...

Estimates of the value of patent rights in China

Huang, Can - United Nations University-Maastricht Economic Research … - 2012

We estimate the value of Chinese invention and utility model patents that were applied for during two periods, 1987-1989 and 1986-1998. We find that patents applied for by foreign entities invariably have higher value than do those applied for by domestic entities, and the gap is significant....
