Companies often restyle their logo to appear more modern. For example, the Apple logo has been modified several times. Such a restyling has legal consequences for trademark protection.
If the new logo differs significantly from the old one, a new trademark registration is required. However, it must first be checked whether the new logo does not resemble trademarks of other companies too closely.
The trademark registration of the original logo is often renewed due to its older protection, even if the logo is no longer in use.
Instead of modernizing, a company may also choose to bring back the classic feel of an old logo in a new design — as Pepsi did in 2023.
