Patent Portfolio Race and Secrecy

Abstract

When firms can protect their innovations by secrecy or lead-time, the additional effect of patent protection is not obvious. This paper shows that when firms compete for a single innovation, patent protection still increases R&D investment but decreases social welfare due to over-investment. However, when firms compete for multiple complementary patents (called a patent portfolio), patent protection decreases R&D investment and decreases social welfare due to under-investment. If firms cannot rely on secrecy, patent protection increases investment regardless of whether firms compete for a single patent or for a patent portfolio.
