How do firms use technological breakthroughs to move beyond their own inventive experience and toward areas of strength for other firms?

Summary

We examine inventive search through which firms move beyond their own prior inventive activity and toward knowledge domains more closely associated with other firms. We call this movement search incursion. Generative inventions make previously infeasible combinations of knowledge possible and can weaken the conditions protecting other firms' advantages. Technological proximity shapes both a firm's ability to use an invention and its exposure to the changes that adoption requires. Using patent data, we examine how the likelihood of search incursion varies with technological proximity and the structure of the firm's knowledge base.
