What are some examples of unregistered marks that Carls Jr. may use?

According to the 2025 Carls Jr. Franchise Disclosure Document, Carls Jr. uses both registered and unregistered trademarks to identify and distinguish its brand. Registered trademarks are those that have been officially registered with the United States Patent and Trademark Office (USPTO) and thus benefit from federal registration protections.

Carls Jr.'s unregistered marks, on the other hand, are not formally registered with the USPTO but are still protected under common law due to the company's use of these marks. Examples of unregistered marks that Carls Jr. may use include short-term product marks related to limited-time offers (LTOs) or similar promotions. Additionally, the trade dress of Carls Jr. restaurants, which refers to the overall visual appearance and design of the restaurants, may also be considered an unregistered mark. Other marks that, while not registered, are protected by common law based upon Carls Jr.'s use of the marks.

As a franchisee, it's important to understand that you are granted the right to use both registered and unregistered Proprietary Marks designated by Carls Jr. in the operation of your franchised restaurant. However, you must adhere to Carls Jr.'s rules and guidelines when using these marks and cannot use them in any unauthorized manner or seek to register them yourself.
