Newegg brings on the smackdown with the "Shopping Cart" lawsuit

If you have ever shopped online, then you have almost certainly come across the shopping cart widget. Items can be added to the virtual cart to save for purchase at a later time, perhaps to give you more time to shop. Once you have your entire purchase ready, a quick click to the "check out" button will complete the order.

While the shopping cart is pretty much ubiquitous on the Internet, one "company" claims that it owns the rights to the virtual cart's use. Soverain Software is a sham business existing to suck money out of other, more successful businesses through patent lawsuits. Soverain had produced the two patents 5,715,314 and 5,909,492 (and, on occasion, a third: 7,272,639) to prove their case against such defendants as Amazon and The Gap, and more recently: Newegg.
