duration of trademark

["Cornett, Cheryl L." <CORNETTC@xxxxxxxxxxxxx>]

I know that federally registered trademark duration is indefinite as
long as the trademark remains in use and is renewed every 10 years.



What is the duration of an unregistered trademark since you wouldn't be
renewing it if it isn't registered?



Thanks, cher
