As you know CIS is a valuable source of information for innovation studies. However, it doesn't provide data about US companies. Therefore, I would like to know whether similar data are also available for US enterprises.
The BRDIS collects data on the current state of research and development in the U.S. business sector. BRDIS provides the U.S. official measure of R&D in the private sector. More info on http://www.nsf.gov/statistics/srvyindustry/about/brdis/faq.cfm
