FIRM STRATEGIES AND TRENDS IN PATENT LITIGATION IN THE UNITED STATES

Patent litigation has been rising rapidly in the United States since the mid-1980s, and particularly so in high-technology industries. The strategies pursued by firms with their patents have a significant influence on their decisions to file suit, and on the outcomes within litigation. The influence of strategic motivations on settlement outcomes is studied in two illustratively different industries – computers and research medicines. Evidence is found for two types of influences – the use of patents (as isolating mechanisms) to protect valuable strategic stakes, and their “defensive” role in obtaining access to external technologies (through mutual hold-up).
