Deciding on a trademark is an important part of successful branding. Many companies then register the mark for protection at the federal level. Part of this process requires considering how the trademark should be classified.
Keep in mind that on your application you must select from one or more of the available categories, which are based on the goods or services you offer. The USTPO provides 45 classes to choose from and, once selected, your trademark protection is limited to that specific area. Further, if you select the incorrect class, your application may be denied.
