Patent Package Sales Up for 1st Quarter of 2015

The Richardson Oliver Law Group (ROL Group) has released statistics (April 30, 2015) on patent packaging purchases for the first quarter of 2015.  ROL Group notes that patent package purchases are up, but also notes that prices are down.  There were around 49 patent packages sold in the first quarter of 2015 compared to between 11 to 38 packages per quarter from the first quarter of 2013 to the fourth quarter of 2014.  The leading purchaser is RPX with 13.5.  Intellectual Ventures, 9051447 Canada, Apple, Rakuten, Domo and Kloninklijke Phillips purchased multiple packages.  What explains the upswing in patent package sales?  Here is a little speculation.  I wonder whether patent packages are at bargain prices because of the relatively recent U.S. Supreme Court cases concerning patent eligible subject matter, attorney fees and claim definiteness, as well as the new procedures at the USPTO.  I suppose, as one leading patent commentator has said, you really only need one good patent (like a bullet).
