International doctoral graduates as inventors in the German innovation system
研究了在德国大学受训的国际STEM博士的专利活动，发现他们与本国申请人合作申请专利的比例偏高，但未显示更多引用本国或其他国际专利。
We study patenting activities of international STEM PhDs trained at German universities to explore their integration into the German innovation system and their role in the international diffusion of technology. International PhD inventors with German inventor addresses file a disproportionate share of patents with applicants from their home countries. Our results do not indicate that they are more likely to cite, or be cited by, patents from their home country or other international patents.
