Yes, they are called “patent trolls” in the electronic industry.
Check out my post #9. In this case, it may in fact not be trolling.
Smartflash was a USB-connected secure device that logged you into a unique site for purchasing entertainment content; it preceded (even) the iPod by a couple of years.
Smartflash partnered with Britney Spears, and one of her lawyers is alleged in the suit to have conveyed material knowledge of the device to Samsung, one of the defendants.
Britney, at the time she was involved with Smartflash was also a celebrity spokesperson for Samsung, thus the connection.
