Compared with the renewal and re-registration of registered trademarks, renewal is more cost-effective. Because during the renewal period, if others apply for registration of the trademark on the same or similar goods, the Trademark Office will generally not grant registration, but if the parties register again, they will be restricted by one year and may be squatted by others.
