Patent litigation: There’s a lot of it, but not all of it is created equal. So says the “Patent Litigation Damages Report,” the first edition of a study that Menlo Park, Calif.-based legal analytics company Lex Machina released Wednesday.

The study looked at all 36,629 patent cases filed and terminated in the U.S. from 2000 to 2013. The majority of cases involved patent disputes over technology, pharmaceuticals and genetically modified organisms (GMOs).
