Press release by Fenwick and West who appear to be IP lawyers in the USA
"The patents unanimously struck down by the Court were for an electronic escrow service for online securities sales. The Supreme Court ruled that an abstract idea like escrow, which has been around for hundreds of years, does not become patent eligible simply by being executed online. Since then, the USPTO has drawn a much tougher line regarding similar patent claims."
They continue talking about how recent changes have made US patent rules more like those of Europe.
