there are thousands of examples, but I just found this to be amusing.Why couldn’t the brick-and-mortar chains simply adopt the Netflix model? Well, they’re doing just that. But there are two huge problems with this copy-cat tactic. First, Netflix won patent protection for its business model of taking orders online and mailing DVDs to customers. To date, imitators such as Blockbuster and Wal-Mart Stores (WMT, news, msgs) haven’t stolen enough business to make it worthwhile for Netflix to spend the money in legal fees to enforce the patent and shut the copycats down, says Hastings. So we don’t really know if the patent will hold up in court. But even if the big video chains successfully challenged the patent and ran a big online-based mail-order business, they’d still have a tough time competing because of their brick-and-mortar overhead.
