It is hard to love a troll, and some feel the same way about patent trolls, the pejorative term for a nonpracticing entity (NPE) that sues a company for infringing its patent. Some feel that NPEs, which do not practice the invention covered by their patent, are like mythical trolls, who lived under bridges and collected tolls, even though they did not themselves build the bridge. Harry Potter taught us to love witches, Shrek taught us to love ogres, but notwithstanding Russ Berrie, trolls tend to get a bad rap. Companies like Apple, Microsoft and Canon have all been sued by NPEs, which often obtain jury verdicts in the hundreds of millions of dollars.
