The U.S. International Trade Commission has determined that NJOY, a company involved in the importation and sale of vaporizer devices, has violated Section 337 of the Tariff Act by infringing on several JUUL Labs patents. As a result, the Commission issued a limited exclusion order prohibiting the import of NJOY's infringing products and cease and desist orders against NJOY. No bond will be required for the importation of excluded articles during the period of Presidential review. This decision was made after a thorough investigation, and the Commission's findings were communicated to the President and the U.S. Trade Representative.
Simple Explanation
Imagine a rule that says you can't copy someone's toys. NJOY was found to be selling toys that copied someone else's design, so they're not allowed to bring those toys into the country anymore.
