Online DVD rental company Netflix Inc. sued rival Blockbuster Inc. for patent infringement Tuesday, asking a federal judge in Northern California to shut down Blockbuster's 18-month-old online rental service and award Netflix damages, according to a copy of the filing.

The first patent, granted in 2003, covers the method by which Netflix customers select and receive a certain number of movies at a time, and return them for more titles.

The second patent, issued Tuesday, "covers a method for subscription-based online rental that allows subscribers to keep the DVDs they rent for as long as they wish without incurring any late fees, to obtain new DVDs without incurring additional charges and to prioritize and reprioritize their own personal dynamic queue -- of DVDs to be rented," the lawsuit said.

Maybe the geniuses responsible for the current law can explain how this "promote[s] the progress of science and useful arts?"
