Triller, a short-video making app, sued rival TikTok for allegedly infringing on some of its patents.
Why it matters: This is the latest in a series of problems for TikTok, which is battling government and corporate critics of its ties to China. It's also the latest in the intellectual property wars among apps, following the dispute between Eko and Quibi.
