A biological patent is like a fancy way of saying that someone has been given permission to own and control a specific living thing. For example, let's say that someone discovers a new kind of plant or animal that has some special feature or ability, like producing a certain chemical or resisting a particular disease. This person can apply for a biological patent, which means that they become the "owner" of that plant or animal and they can stop anyone else from using it without their permission.
When someone has a biological patent, it's kind of like owning a toy or a game. They get to decide how it gets used and who gets to play with it. But just like with toys, sometimes people argue over who gets to play with something or how it should be used. This is often the case with biological patents, especially when they involve things like genetically modified crops or animals that can be used for medical research.
Overall, biological patents are a way to recognize the hard work of scientists and researchers who make important discoveries about living things. However, they can also be controversial because some people feel that they give too much power to a few individuals or organizations and limit the ability of others to benefit from important scientific discoveries.
