The relationships between intellectual property rights (IPRs) and structural change are examined in this paper. Intellectual property rights are a complex, multifaceted area and one in which corporate strategies are poorly understood. Nevertheless, it is argued here that IPRs can affect firm entry, can make vertical integration in downstream industries more or less necessary, and can create financial incentives for downstream mergers and acquisitions. Hence, IPRs can have significant structural impacts.

Key words: Intellectual property rights; agrobiotechnology; industry structure; research and development (R&D;).
