US patent litigation falls to levels not seen since 2011

The number of patent litigation cases in the US dropped dramatically in the first three months of this year, reaching levels not seen since 2011 – the year when the America Invents Act was signed into law. A total of 947 new patent lawsuits were filed between January and March, according to data from Unified Patents, down from 1,554 in the fourth quarter of 2015. That is the lowest number since the third quarter of 2011 when 924 new cases were filed.
