You cannot patent a logo, because patents are meant for inventions and technical solutions, not brand designs. However, you can protect your logo with a trademark.
A trademark gives you exclusive rights to use your logo in connection with your goods or services and prevents others from using a confusingly similar design.

By registering your logo as a trademark, you turn it into a legally protected brand asset.
Once registered, they typically last for 10 years and can be renewed indefinitely in 10-year periods, as long as you continue to use the logo in commerce.
