The ITC has the authority to block "articles" and the case before the U.S. Court of Appeals for the Federal Circuit hinges on defining that word. Align, backed by the movie, music and publishing industries, argues it encompasses all goods. To say otherwise would "create a gaping loophole in the statute," said Align lawyer Stephen Kinnaird of the firm Paul Hastings in Washington.
ClearCorrect Operating, which uses the treatment plans from its Pakistani partner to made models of braces in Texas, said it's only tangible goods.
"An article is something that can be stopped at the customs house, stamped with a trademark, put on a rail line." said ClearCorrect lawyer Michael Myers of McClanahan Myers Espey in Houston.
Congress never intended to give the trade agency authority for electronic signals, leaving that task to a communications regulator, Myers said. Congress has been holding hearings on how to deal with streaming data, he said.
Internet companies including Google and Facebook argue that an order from the ITC would amount to onerous demands that would force service providers to figure out from which country a file was sent. The internet knows no boundaries and sends files using the most efficient route.
A decision "has sweeping implications for the internet and the ability of companies to operate efficient, dependable global networks," the Internet Association, whose members include Facebook, Google, Amazon.com, Twitter and Uber, said in a court filing.
Those concerns are a "red herring," ITC lawyer Sidney Rosenzweig told the panel. The agency has no interest in policing services, phone calls or emails, and internet service providers would be protected from any liability under the Digital Millennium Copyright Act if they take steps to prevent illegal postings, he said.
The issue is digital goods "that are bought and sold in commerce, exactly the way physical goods are," Rosenzweig said.
The three judges on the panel said they know their decision, either way, could have broad ramifications beyond the dispute over braces.
"The world is changing more rapidly" than the laws governing it, said Chief Judge Sharon Prost.
It isn't just movies and music. The Align case involves electronic dental treatment plans from Pakistan that are used to make 3D models of the invisible braces in Texas. As 3D printers become both more affordable and more precise, counterfeiters may bypass the physical customs house and instead transmit information from overseas across national borders undetected only to have someone in the U.S. print the product.
"We have the same problems that folks had in the 1920s when they wrote this" law creating the ITC, said Dan Robbins, the Motion Picture Association of America's lawyer for technology legal work. "It's going to become a bigger and bigger issue. If they duck it today, they'll see it again."
