Recently, a US court in Virginia upheld a ruling that stated that the US doesn't have as strict rules as Europe when it comes to naming foods. The case centered around the use of the name "gruyere" for cheese. The court's decision was that cheese can be called "gruyere" no matter where it was made.
This ruling was seen as a victory for US dairy groups, who have been calling cheese "gruyere" for decades, regardless of its country of origin. The court agreed with the US Patent and Trademark Office, which had rejected a claim by two groups representing cheese producers from France and Switzerland for a mark that would restrict the use of "gruyere" to cheese from Gruyère itself.
The court's decision was based on the fact that people in the US already understand "gruyere" to mean a type of cheese, so it's a generic term. The French and Swiss groups argued that the name should only be used for cheese produced in the region of Gruyère in Switzerland. They said that the name "gruyere" is protected in Europe, where strict rules govern the designation of origin for foods.
