Thomas Warfield updated his blog the other day with one of the most absurd patent disputes I’ve heard of lately. Warfield’s company makes some of the best computer solitaire games available (I know because they’re the only games that my wife will interrupt Civ2 to play). Now he’s receiving letters from a company claiming that computer solitaire games infringe on patents the company owns — specifically, 5,823,879, 6,183,366 and 6,264,560.
