Facebook knocked out another video compression patent that helps deliver songs and videos from servers to mobile devices that a patent holding company accused the social media giant of infringing.

The Patent Trial and Appeal Board July 19 ruled that claims in a patent owned by Skky LLC were obvious and unpatentable because they were covered by previous inventions.

The dispute stems from a 2016 patent infringement suit Skky filed against Facebook and its Instagram subsidiary in the U.S. District Court for the District of Minnesota. Skky targeted Facebook and Instagram’s compressed video and audio content, including revenue-generating advertisements, that the companies relay to social media users.

Facebook has filed over a dozen patent review petitions since 2016 challenging the validity of nine patents that Skky asserted against it in a Minnesota federal court. It succeeded in canceling claims in three other Skky patents in July, but the board had declined to take up petitions on the remaining five patents.

The July 19 decision completes the board’s review of Facebook’s petitions, shifting the legal stage back to the courtroom. The Minnesota court had stayed the case until the board ruled on the petitions, according to court documents.

The case is Facebook Inc. v. Skky LLC, P.T.A.B., No. IPR2017-00687, 7/19/18
