Netflix on Tuesday sued rival Blockbuster, claiming patent infringement and maintaining that, in the words of a company spokesman, "From top to bottom, Blockbuster has deliberately and willfully copied Netflix's business model." In its filing, Netflix asked a federal court in San Francisco to shut down Blockbuster's online rental service. It also seeks unspecified damages.
I'm not a lawyer and I don't know the details of the case, but on first blush it seems to me that if Netflix has a valid complaint, then Blockbuster should have sued Hollywood Video years ago. And Colgate should have sued Crest. And Coke should totally try to get the courts to stop all sales of Pepsi.
