 The plaintiffs had argued that four of YouTube's software functions relating to user uploads disqualified the service from safe harbor protection, but the appeals court agreed with the lower court in that three of the functions—transcoding, playback, and related-video thumbnails— were within the scope of safe harbor.The fourth function, syndication, was remanded for further fact-finding.On April 18, 2013, Judge Stanton issued another order granting summary judgment in favor of YouTube.
