Opening Up Intellectual Property Strategy: Implications for Open Source Software Entry by Start-up Firms
研究了IBM在2000年代中期宣布不对开源社区主张专利并创建专利共享池等知识产权战略，如何刺激了软件初创企业推出新的开源产品，且这种影响在市场创新累积性和专利集中度较高时更强。
We examine whether a firm’s intellectual property (IP) strategy in support of the open source software (OSS) community stimulates new OSS product entry by start-up software firms. In particular, we analyze the impact of strategic decisions taken by IBM around the mid-2000s, such as its announcement that it will not assert its patents against the OSS community and its creation of a patent commons. These decisions formed a coherent IP strategy in support of OSS. We find that IBM’s actions stimulated new OSS product introductions by entrepreneurial firms and that their impact is increasing in the cumulativeness of innovation in the market and the extent to which patent ownership in the market is concentrated.
