PHILADELPHIA — Internet auction site eBay (Nasdaq: EBAY) is being sued for $3.8 billion for allegedly infringing on patents held by XPRT Ventures LLC for its payment systems.

XPRT Ventures, which represents holders of the patents, on Tuesday sued eBay and its subsidiaries – PayPal Inc., Bill Me Later Inc., Inc. and StubHub Inc. The lawsuit was filed in the U.S. District Court in Delaware.

XPRT, based in Greenwich, Conn., accuses eBay of violating six patents that let shoppers make purchases online using alternative forms of payment instead of their credit cards, among other processes.

eBay did not immediately return a call for comment.

XPRT’s attorneys say the patent holders aren’t seeking an injunction but want to be "fairly compensated" for their ideas.
