There are a few key differences between trademarks and copyrights. First, trademarks protect brands and logos, while copyrights protect creative works like books, music, and art. Second, trademarks can be registered with the government (in the US, this is done through the US Patent and Trademark Office), while copyrights are automatically created when a work is created and do not need to be registered. Finally, trademarks can last indefinitely if they are properly maintained, while copyrights generally last for the life of the author plus 70 years.
