When do trademarks expire?

Answer 1

Trademark registrations are valid for 10 years, and can be renewed every 10 years for as long as the mark is in use. Some of the oldest corporations still in business, such as German and Belgian breweries, have logos that have been in use for 700 years or more and continue to be protected.

Mickey Mouse, for example, is a trademark, so even as Disney's copyrights start to expire, Mickey Mouse will continue to be protected.

Answer 2

After six years, after ten years, and every ten years after that.

Answer 3

In the US, works of corporate authorship are protected for 95 years from publication or 120 years from creation, whichever expires first.
