Video Poker Patents

[bigboy]

I was just curious to know if anyone has knowledge of why Jay Walker(founder of Priceline), has been making a run on V.P. patents for the past year or so. I know that his original company- Walker Digital(to whom the patents are being issued) is generally regarded to be a patent mill of sorts. Does anyone know what the ramifications of walker's actions will mean for player's and game manufacturer's? If anyone is interested, the latest patent issued is #7,201,655 and can be viewed at http://www.uspto.gov .
