Samsung Gets New Review of Video Data Coding Patent
Written July 30, 2019
The US Court of Appeals for the Federal Circuit on July 12, 2019, canceled a Patent Trial and Appeal Board decision upholding Infobridge Pte. Ltd.'s video coding patent (Patent No. 8,917,772) and sent it back to the board for review. Samsung Elecs. Co. v. Infobridge Pte. Ltd., Fed. Cir., No. 18-2007, 7/12/19.
Samsung in 2017 challenged the validity of the ‘772 patent, which describes technology that helps encode and decode video data. Samsung argued that the patent was disclosed in a working draft of the HEVC standard.
The board said the working draft wasn’t publicly accessible a year before Infobridge filed the ‘772 patent application.
The Board wrongly analyzed whether an email sent via a listserv made the draft publicly accessible, the Court said, because the listserv included members of the HEVC standard’s working group and other “interested individuals” to which anyone with a valid email address could subscribe.
