This paper assesses the impact of adopting a post-grant review institution in the US patent system by comparing the 'opposition careers' of European Patent Office (EPO) equivalents of litigated US patents to those of a control group of EPO patents. We demonstrate several novel methods of...

The recent surge in U.S. patenting and expansion of patentable subject matter has increased patent office backlogs and raised concerns that in some cases patents of insufficient quality or with inadequate search of prior art are being issued. At the same time patent litigation and its costs are...

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). The purpose of this document is to describe the Patent Examination Dataset (PatEX), make a large amount of information from the...

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...

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....

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...

This paper introduces a new innovation data source to re-examine how spatial distance affects the diffusion of ideas and innovations in an economy. We exploit the descriptions of products and services contained in U.S. trademark registrations during 1980-2012 to identify terms (tokens) not...

This chapter provides evidence on how young technology startups are employing intellectual property (IP) protection when innovating and competing in the United States. Although researchers and teachers of university technology transfer often think only in terms of patents and the Bayh-Dole Act,...

The determination of patent damages lies at the heart of patent law and policy, yet it remains one of the most contentious topics in this field, particularly as regards the calculation of a reasonable royalty. In March 2016, the Berkeley Center for Law & Technology convened a workshop of leading...
