Parasites who will suck the money from anything they can, including a failing retailer:
Janet Dhillon from J.C. Penney (which has the terrible misfortune of being located in the patent-troll-friendly Eastern District of Texas) explained that in the last four years her company has been hit with over two dozen patent lawsuits—all from patent trolls.
It has been sued by trolls for such basic things as displaying catalog images and having drop down menus on its website. Before the rise of the patent troll, they had no patent litigation at all. That makes sense. After all, it is a clothing retailer, not a technology company.
