Courts, commentators, and companies have devoted enormous time and energy to the problem of standard-essential patents (SEPs) – patents that cover (or at least are claimed to cover) industry standards. With billions of dollars at stake, there has been a great deal of litigation and even more...

In theory, we have a unified patent system that provides technology-neutral protection to all kinds of technologies. However, we have recently noticed an increasing divergence between the rules actually applied to different industries. Biotechnology provides one of the best examples. In...

We test empirically whether purchased patents that are litigated fare better or worse than litigated patents that aren’t purchased. We identified every case filed in 2009 and 2010 that had a definitive winner and had information on the presence or absence of an assignment or other transfer....
