Wyoming Cancellation of Trademark or Service Mark is a process where a trademark or service mark registered in the state of Wyoming can be cancelled. This cancellation can take place due to various reasons, including abandonment, fraud, non-use, non-renewal, or change of ownership. There are two types of Wyoming Cancellation of Trademark or Service Mark: voluntary cancellation and involuntary cancellation. Voluntary cancellation occurs when the trademark owner submits a request to cancel their mark, either through the Wyoming Secretary of State’s Office or the United States Patent and Trademark Office. The request must be accompanied by a statement of the reasons for the cancellation. Involuntary cancellation occurs when a third party makes a request to cancel the mark due to either abandonment, fraud, non-use, non-renewal, or change of ownership. This request must also be accompanied by supporting evidence. Once the request is received, the Wyoming Secretary of State’s Office or the United States Patent and Trademark Office will review the evidence and make a determination. If the request is accepted, the mark will be cancelled.
