I have read the lawsuit and the patent. Just to let you know that a Patent is not the be all and end all that it might sound. If someone can make an improvement and its open then there not much the Patent holder can do, but file a lawsuit for infringement, and hope try to get 6 folks to say that the Patent was infringed. I understand that they want to "protect" their Patent and the way you protect your Patent is to file an lawsuit. Patent lawsuit are contests, generally the one who has the most money wins.
