Computer Solitaire Patented?

Sadburger writes "Saw this over on GameDev: 'Thomas Warfield of Pretty Good Solitaire is reporting in his most recent blog that: 'My company has received the following letter from a law firm claiming to have a client that has patented computer solitaire. And by extension, all computer card games. I am not kidding.' Patent law strikes again...' Anyone know a good patent lawyer?" Someone alert the educational sector, since at least half my programming classes involved solitaire, poker, or blackjack.
