The founders of Internet telephone service Skype are suing its current owner eBay Inc and an investor group, according to a report on the Wall Street Journal's website.

The lawsuit from Niklas Zennstrom and Janus Friis is over theft of peer-to-peer technology, according to the Journal.

The report comes after a consortium including venture firm Index Ventures agreed to pay $1.9 billion to Internet auction house eBay for a 65 percent stake of Skype.

It also comes after Web TV firm Joost, also owned by Zennstrom and Friis, removed its high-profile chairman Mike Volpi, who joined Index Ventures. (Reporting by Sinead Carew and Ritsuko Ando; Editing by Tim Dobbyn)
