This new suit comes as a response to an earlier claim by Netflix that "Blockbuster Online infringed on patents it held."

Netflix maintains that when it came on the scene in 1999 the service they offered wasn't "obvious." Marshall Grossman who is representing Blockbuster in this case claims that "in the late '90s companies were devising ways 'to use the Internet for everything under the sun, including Santa Claus wish lists from children.'"
