Unlike most of the other jurisdictions discussed in this book, the United States (US) does not currently have, nor did it ever have, a utility model or other system of second-tier patent protection. This being said, discussion and debate over the institution of such a system in the US has been ongoing for more than a century. In this chapter, we discuss the history and current status of this debate, as well as alternative approaches that US agencies and legislators have taken to address the needs and concerns of small and medium-sized inventors.
