Trademark rights (other than those conferred by well-known marks which enjoy a more far-reaching protection in a number of countries) are typically limited to goods or services which are idetical with or similar to the goods and services for which the marks are registered. Thus, while you may have exclusivity over your mark for certain goods or services in a given class or several classes of goods and services, another company may legitimately use the same mark for goods or services which are not similar. Under most modern trademark laws, you may apply for trademark protection in more than one class if appropriate. However, some countries still require separate applications for each class of goods or services. Most countries adhere to or apply the system of International Classification of Goods and Services which divides goods into 34 classes and services into a further 8 classes.
