The innovation process of Huawei and ZTE: Patent data analysis

This study compares the innovation process of Huawei and ZTE in China using their patent data. By using patent statistics and raw data, this study provides more detailed findings than what statistics alone can provide. Huawei and ZTE were selected for this study mainly because they were the only Chinese firms that ranked among the top 100 PCT applicants in 2011. This study investigates the difference in the innovation process in R&D between Huawei and ZTE by analyzing (1) domestic and international patent application patterns, (2) granted patents, (3) co-applicants and inventors, (4) knowledge accumulation inside Huawei and ZTE, and (5) knowledge spillover to domestic and foreign firms.
