Dr. M.C. Roco was partially supported by the Directorate for Engineering, NSF. The authors thank esp@cenet for making the worldwide database available for research. Funding Information: developing countries have intensified their nanotechnology R\&D efforts of late [2]. Patent analysis can reveal the Patterns scope and direction of nanotechnology R\&D trends and has been used to assess the development of different research communities and technology fields [3], [4]; to study nanotechnology patents published by the U.S. Patent and Trade-mark Office (USPTO), the European Patent Office (EPO), and the Japan Pat-ent Office (JPO) [5], [6]; and to exam-ine the impact of U.S. National Science Foundation grants on USPTO nano-technology patents [7].",
