2013 Patent Litigation Year in Review

The world of U.S. patent litigation has  changed dramatically in the last five years:  total patent cases filed in district courts have more than doubled since 2008, the American Invents Act was passed in 2011 and took effect in 2012, and cases such as Apple-Samsung have captured headlines with eye-popping damages awards for patent infringement in widely used products. This report draws on Lex Machina’s unique and rich Legal Analytics data on U.S. District Courts and judges, law firms, parties, patents, case merits decisions, damages awards, and International Trade Commission (ITC) investigations and Administrative Law Judges (ALJs).

In 2011 Congress directed the Government Accountability Office (GAO) to study the effects of non-practicing entities (NPEs) on patent litigation.

Prior User Rights/Inventorship Study (2011)

Congress  has  essentially  asked  the  U.S.  Patent  and  Trademark  Office  an  impossible question: What would happen if prior user rights were implemented in the United States? More concretely, it has asked as to the impact of this defense on innovation, and as to non-U.S. implementations of prior user rights.  But problems exist with both approaches.  Future innovation rates are hard to predict.   Foreign data may be hard to gather comprehensively. Moreover,  the  application  of  prior  user  rights  in  exogenous  procedural  environments  (i.e., foreign  courts)  may  be  misleading.  A  better  approach  […]
