TikTok's attempt to overturn a ban of its service in the US has been rejected.
The federal appeals court upheld the law, which will see TikTok blocked in the US unless the Chinese owner ByteDance sells its regional operations.
TikTok unsuccessfully argued that the law was unconstitutional because it represented a "staggering" impact on the free speech of its 170 million US users.
However the court said that the law "was the culmination of extensive, bipartisan action by the Congress and by successive presidents," and a matter of national security.
TikTok said that it will continue to fight the ban, and will lodge an appeal with the US Supreme Court. "The Supreme Court has an established historical record of protecting Americans' right to free speech, and we expect they will do just that on this important constitutional issue," the company said in a statement.
"Unfortunately, the TikTok ban was conceived and pushed through based upon inaccurate, flawed, and hypothetical information, resulting in outright censorship of the American people."
The ban is currently set to be enforced on January 19, one day before Donald Trump is set to be sworn in as president.
Trump previously unsuccessfully tried to have TikTok banned, but has since said that he would "save" the app and that any ban could help Facebook.
During Trump's attempted ban, Oracle and Walmart were on track to acquire TikTok's US operations. While the deal fell through, TikTok has since begun moving all of its US data to Oracle Cloud.
In Oracle's annual report filing earlier this year, the company has stated that the ban would have a negative effect on its revenue and profits.
"In April 2024, the US president signed into law a bill that will make it unlawful to provide Internet hosting services to TikTok that are used to enable the distribution, maintenance, or updating of TikTok for users within the US if certain steps are not taken by TikTok’s owners within a set time frame.
"If we are unable to provide those services to TikTok, and if we cannot redeploy that capacity in a timely manner, our revenues and profits would be adversely impacted."
