| Abstract | In 1976 Japan expanded the scope of its patent law by extendinJ ~ coverage to newly-developed chemical and pharmaceutical l1roducts. Previously the patent la", had only provided protection to new production l1rocesses for manufacturing chemicals and pharmaceuticals. We use rate of return data from the Tokyo Stock Exchange for Japanese pharmac:eutical companies to determine whether these fums gained from the introduction of pharmaceutical product patents. Using two different methodologies we find that the stock price for a portfolio of pharmaceutical firms and for individual fIrms significantly increased in response to the passage of the 1975 patent law. |
