Sueball sees social network squaring off against app upstart in UK branch of worldwide fight Gareth Corfield Fri 16 Apr 2021 // 08:30 UTC Share Copy A legal battle between a company which says Facebook Live infringes one of its patents and the anti-social networking biz is currently playing out in the High Court of England and Wales as part of a long-running multinational legal battle. Voxer, which The Registerbriefly covered in 2011 when it launched its “walkie-talkie for the modern age”, is locked in a courtroom skirmish with Facebook over a patent for its live streaming video technology. The case is notable because Facebook claims Voxer infringed its intellectual property and wants Voxer’s patent declared invalid. For its part, Voxer wants to alter its disputed IP, EU patent 2,393,259, and then have the High Court declare that it doesn’t infringe any of Facebook’s patents for its Live technology.
