Pretty obvious patent trolling if they're only going for this rather smalltime developer and none of the high profile F2P game developers and big time game developers releasing AAA games with a premium currency.
Not really. The patent was filed in 2000. Approved in 2007. It hasn't changed hands. The company makes software.
Believe it or not, this is the US system working as intended.
An obvious troll is a patent holding company, with no products, who purchases old patents, then goes on a suing spree for any company that uses printers.
