Innovation, Patenting and Appropriability: Survey Evidence from a Nationally Representative Sample of U.S. Firms

Abstract We document a series of stylized facts about how firms seek to protect the rents from innovation, using a large nationally representative survey of U.S. businesses over the period 2008-2015. Just 1.4 percent of firms obtain patents, but these patenting firms account for 87 percent of R&D investment. Firms consider utility patents less important than other forms of IP protection, like trade secrets, trademarks, and copyrights. Firm industry and size are strongly correlated with firms’ use of all types of intellectual property, but firm-age is not. Implications for innovation research and policy are discussed.
