Despite increased focus on understanding how firms appropriate the returns from innovation, our knowledge regarding firms' behaviour in less developed economies (LDEs) is still scant. This paper provides a nuanced view as to how firms that are not at the technological frontier attempt to capture value when they encounter fragile patenting conditions. I analyse a unique dataset on innovative activities in Brazil. My findings reveal the effects (if any) of a number of factors on the use of a wide range of appropriability mechanisms. These factors include measures of knowledge intensity, novelty of products and processes, firm size, degree of competition, innovation cooperation, government support for innovation, and type of ownership. In addition, my empirical exercise provides evidence of the extent to which firms in an LDE adopt different appropriability mechanisms in pairs. Overall, this paper indicates that even in the absence of an effective patent system, firms do use patents. However, there are other patterns of appropriability in which firms use design (being registered or not registered accordingly), lead-time or trademarks in association with other means of appropriation.
