Dan Rosenberg on "a patent crisis that doesn't exist"

From a letter in the New York Times by Dan Rosenberg concerning patent reform bills such as the Innovation Act:

The bills are influenced by headline-catching “studies” using privately held and generated data to paint the picture of a patent crisis that doesn’t exist. According to federal data and respected academics whose data are available to all, the number of patent litigation cases as a percentage of patents issued has been shown to be stable over decades.
