I have prepared a database of Top 50 companies of the world by
number of patents filed. The database contains the R&D expenditures
for year 2017 and 2018, and their number of patents filed in the year
2017 and 2018. If you are interested to get a copy of the same, please
drop in your email ID and I will give you access.
