A trade mark is a sign that you can use to distinguish your business goods or services from those of other traders. A trade mark can be represented graphically in the form of your companys logo or a signature. Through a registered trade mark, you can protect your brand (or mark) by restricting other people from using its name or logo. Once acquired, a trade mark can last indefinitely as long as you renew it every 10 years. Because a registered trade mark is a form of IP, you can license or assign it to others.
