What are the types of Patent?

The video tutorial explains the different types of patents: utility, design, and plant patents. Utility patents protect novel and useful processes, methods, or compositions that are non-obvious to the public. Design patents cover the ornamental or aesthetic aspects of a product, preventing others from copying the design. Plant patents protect unique genetic combinations of plants that offer desirable characteristics. The video also discusses the duration of protection for each type of patent.
