NormalVisual writes "'It's a really tough time to be a patent owner', said Soverain Software, LLC president Katharine Wolanyk, after the Supreme Court refused to hear their appeal after the U.S. Court of Appeals for the Federal Circuit invalidated three of Soverain's shopping cart patents. Soverain had sued Newegg for allegedly infringing the patents in question, and had won in the U.S. District Court for the Eastern District of Texas. Newegg later had the decision overturned on appeal, with the court ruling that the patents in question were obvious, and thus invalid."
