Analysis of patent prosecution in China

This paper by Gaetan de Rassenfosse looks for traces of discrimination against foreigners in the patent prosecution process, building on earlier work. It focuses on the case of China, looking in particular at patent applications declared as essential to a technological standard, so called standard-essential patents (SEPs). It finds there is discrimination in the treatment of such patent applications, which are less likely to be granted and/or to take longer to grant.
