What do you think of "business-method" patents? Did you know that Priceline.com has a patent on reverse auctions, the name-your-price method of buying?

I just read about another business-method patent. Let's say you visit a Kentucky Fried Chicken outlet, order your meal, and the total comes to $6.42. Then the cashier says, "I have a deal for you. For your leftover change, you can get either a small drink or a chicken strip." You then choose the small drink which usually sells for $1.10, bringing your total to $7. This method is called up-selling, and is patented by Walker Digital Corp., the same Jay Walker who founded Priceline.com. A cut of the upsell will go to his company.

It seems like patenting is getting out of hand. What do you think?
