How Newegg crushed the “shopping cart” patent

Soverain will lose the $2.5 million it stood to gain from Newegg, as well as two much bigger verdicts it won against Victoria's Secret and Avon. Those two companies were ordered to pay a total of almost $18 million, plus a "running royalty" of about one percent, after a 2011 trial. The ruling in the Newegg case is a total wipeout for a patent troll that had squeezed many millions from online retailers, was backed by big-firm lawyers, and was determined to collect hundreds of millions more.
