To clarify, Uggs originated in Australia and are a generic term here.
Deckers owns a trademark outside Australia and is enforcing it against people in Australia.
It would be like if a US company registered Champagne as a trademark then enforced it against French companies selling it.
I see. Similar to Balsamico di Modena / generic balsamic vinegar?
Does non-PDO Parmesan exist in Italy? In the US, "Parmesan" is usually some kind of domestic hard cheese that lacks maturity. The genuine Parmigiano Reggiano costs around 3x.
Champagne is absolutely not a "generic" product in the US.
While some California wines were and still are sold as "California Champagne", there was a court decision back in 2006 which affirmed the same protected trademark for Champagne as in the rest of the world, with the caveat that wineries already using the "Champagne" name would be grandfathered in and permitted to continue doing so.
A bottle of Champagne made in the US will be labeled with its origin, and no one can start a winery and start selling Champagne in the US. That's not the same thing as "generic".
I guess it's "generic" in the sense that everyone calls a sparkling wine "champagne", same as everyone calls a copier a "Xerox machine", but if some other company would try to sell their copier using the Xerox name, they would still be sued by Xerox (the company)?
