A surprisingly small amount of empirical research has been focused on the process of obtaining a patent grant from the United States Patent and Trademark Office (PTO). One major reason for this lack of research has been the paucity of readily-available data on the examination of applications....

In recent years a great deal of attention has been paid to patent reform. This debate is exemplified by recent popular publications (Jaffe and Lerner, 2004; Bessen and Meurer, 2008), as well as publicized patent litigation such as the NTP v. Research-in-Motion patent litigation (the Blackberry...

While records of the assignments (transactions) affecting US patents and patent applications have been maintained by the US Patent & Trademark Office (USPTO) for over 40 years, few researchers have used them. To help remedy this deficiency, the USPTO Office of Chief Economist is releasing...

Patent scope is one of the important aspects in the debates over “patent quality.” The purported decrease in patent quality over the past decade or two has supposedly led to granting patents of increased breadth (or “overly broad” patents), decreased clarity, and questionable validity....

In this study, we use carefully constructed matched samples of litigated and non-litigated patents to investigate the characteristics that predict litigation. We define different control groups based on filing characteristics and value correlates (or both), and test the extent to which...

Patent classification systems are largely designed for administrative purposes, limiting their value for most research purposes. To address this deficiency, Hall, Jaffe, and Trajtenberg (2001) developed a higher-level classification for the National Bureau of Economic Research (NBER) Patent...
