AT&T Files Patent Suit Against PayPal, eBay

AT&T filed a patent infringement suit against PayPal and eBay alleging that their online payment systems infringe an AT&T patent covering transactions in which a trusted intermediary securely processes payments over a communications system such as the Internet. AT&T's patent was originally filed in 1991 and was granted in 1994. AT&T said it has unsuccessfully tried to license the patent to the two companies for the past year.
