Although patent reform is not a partisan issue, it has divided those who write and think about the patent system for a living. Earlier this year, 51 law and economics professors wrote a letter to Congress pointing to the “large and increasing body of evidence” supporting legislative patent reform. Weeks later, 40 professors shot back, expressing “deep concerns with the many flawed studies.” We aren’t saying who was right, because one of us signed the second letter and the other authored a number of the contested studies. One of us joined the Obama administration to support patent reform, the other opposes it.
But there is one issue upon which we — and most stakeholders — agree: The staggering concentration of patent cases in just a few federal district courts is bad for the patent system. We believe that changing where patent lawsuits can be filed will solve many of the problems in the debate.
Under a 1990 federal circuit court ruling, defendants can be sued in any district where they sell their products, which is basically anywhere. According to a forthcoming paper by Professors John Allison (University of Texas at Austin), Mark Lemley (Stanford) and David Schwartz (Northwestern), non-practicing entities — pejoratively referred to as “patent trolls” — bring a majority of the patent cases decided in the Eastern District of Texas. The issue is not limited to trolls, however: Kraft Foods is a plaintiff in Delaware in a current case on this issue.
