November 2007Competing on Standards? Entrepreneurship, Intellectual Property and the Platform Paradox
with Timothy S. Simcoe, Stuart J.H. Graham: w13632
This paper studies the intellectual property strategy of firms that participate in the formal standards process. Specifically, we examine litigation rates in a sample of patents disclosed to thirteen voluntary Standard Setting Organizations (SSOs). We find that SSO patents have a relatively high litigation rate, and that SSO patents assigned to small firms are litigated more often than those of large publicly-traded firms. We also estimate a series of difference-in-differences models and find that small-firm litigation rates increase following a patent's disclosure to an SSO while those of large firms remain unchanged or decline. We interpret this result as evidence of a "platform paradox" -- while small entrepreneurial firms rely on open standards to lower the fixed cost of innovation, th...
October 2004Jurisdictional Advantage
with Roger Martin: w10802
Our objective in this paper is to define jurisdictional advantage, the recognition that location is critical to firms' innovative success and that every location has unique assets that are not easily replicated. The purpose is to be normative and policy oriented. Drawing from the well-developed literature on corporate strategy, we consider analogies to cities in their search for competitive advantage. In contrast to the more passive term locational advantage, our use of the term jurisdiction denotes geographically-defined legal and political decision-making authority and coordination. Thus, jurisdictions may be constructed and managed to promote a coherent activity set. We review recent advances in our understanding of patterns of urban specialization and the composition of activitie...
May 1997The Impact and Organization of Publicly-Funded Research and Development in the European Community
with Frank R. Lichtenberg: w6040
This paper examines R&D activities in the European Community using the Community R&D Information Service (CORDIS) databases. We find that a country's private companies tend to be specialized in the same scientific fields as its universities and public organizations. In addition, we construct indicators of the degree of R&D tacitness and find that greater expected ability to communicate research outcomes encourages less centralized R&D programs. Programs that yield tangible results are less geographically and administratively centralized. The more that research leads to codifiable knowledge, the less centralized R&D activity needs to be.
