It’s about time common sense prevailed. Even though Apple had the gall to deny it, “app store” is as obviously descriptive of a store selling apps as “book store” is of a store selling books, or “grocery store” of a store selling groceries. Insisting on trademark protection was ridiculous.
Actually, that reminds me of the time way back when that Barnes & Noble (I think it was B&N, anyway) tried to bring a false advertising claim against Amazon for saying that they were the world’s largest book store. The idea was that since Amazon didn’t have a physical storefront, they weren’t a book store, but a book seller. I seem to recall that didn’t stick either, but took a similarly ridiculous time to settle out.
