LONDON , England ( CNN ) -- A legal battle has put the future of Skype in jeopardy , according to eBay , which owns the online communications system . Skype 's online phone and video communication service has been incredibly popular . If Skype loses the right to use a key part of its software and ca n't create an adequate replacement , `` Skype 's business as currently conducted would likely not be possible , '' eBay said in its quarterly filing with the U.S. Securities and Exchange Commission . There is no sign of Skype disappearing soon -- a relief to the more than 480 million registered users who have video or telephone conversations online through the technology . But the battle with Joltid , the company that created the piece of technology at issue , shows no sign of being resolved anytime soon , either . Joltid complains that Skype broke its licensing agreement to use the technology . Skype filed suit against Joltid in Britain , saying it could not terminate the license agreement ; Joltid struck back with a counterclaim saying Skype had broken the agreement . A trial is scheduled for June 2010 , eBay said in the SEC filing . `` Although Skype is confident of its legal position , as with any litigation , there is the possibility of an adverse result if the matter is not resolved through negotiation , '' eBay writes . `` Skype has begun to develop alternative software to that licensed through Joltid . However , such software development may not be successful , may result in loss of functionality or customers even if successful , and will in any event be expensive . '' In an e-mail to CNN , Joltid said Skype `` accessed Joltid 's source code and modified it -- Joltid then claimed a breach of license . '' Skype denies any breach . `` Joltid is enforcing its rights in the courts , '' Joltid said in the e-mail . `` Like any member of the creative industries , Joltid will defend its innovations with determination . '' CNN 's Diana Magnay and Josh Levs contributed to this report .
