Search Technology and the Georgia Tech Science, Technology & Innovation Policy (STIP) Program are examining the evolution of corporate involvement in nanotechnology R&D. With NSF support (starting April, 2020), we are analyzing corporate research publishing and patenting since 1991, globally and in the US. Patent analysis challenges include: applying a multi-part PatStat database search, including noise exclusion, and consolidating patent applications into INPADOC fields, while distinguishing first patent filings. We are also separating corporate from other assignees and geo-coding to map US company activities. Stay tuned for enhanced tech mining tools to combine patents and research publications.
