Because it has already be we discovered and patented I guess that's why

Biopatents are legal protections granted to inventors or researchers who have made significant discoveries or inventions in the field of biotechnology. These patents provide exclusive rights to the patent holder to use, sell, or license their invention or discovery for a specified period of time.

Biopatents are applicable for various aspects of biotechnology, including the formation of new products, unearthing DNA sequences, and using existing technology to produce new products. However, the discovery of cell lines is not applicable for a biopatent.

Explanation:
- Formation of new products: Biopatents can be granted for the development of new products or processes in the field of biotechnology. This includes the creation of new drugs, genetic engineering techniques, diagnostic tools, and other biotechnological innovations. By obtaining a biopatent, inventors or researchers can protect their intellectual property rights and have the exclusive right to use and commercialize their invention.

- Unearthing DNA sequences: Biopatents can also be obtained for the discovery of new DNA sequences. This includes identifying novel genes, genetic mutations, or other genetic elements that have not been previously characterized. By patenting these DNA sequences, researchers can prevent others from using or commercializing their discoveries without permission.

- Using existing technology to produce new products: Biopatents can also cover the use of existing technology or techniques to produce new products or achieve new results. This includes applying established biotechnological methods in innovative ways to develop new therapies, treatments, or products. By obtaining a biopatent for such inventions, researchers can protect their rights and receive recognition for their contributions to the field.

- Discovery of cell lines: However, the discovery of cell lines is not applicable for a biopatent. Cell lines are populations of cells that have been derived from a single cell or a group of cells and can be continuously cultured in the laboratory. While cell lines are valuable tools in biotechnology and biomedical research, the discovery of a cell line itself is not considered an invention or a new product. Therefore, it does not meet the criteria for obtaining a biopatent.

In summary, while biopatents can be obtained for the formation of new products, unearthing DNA sequences, and using existing technology to produce new products, the discovery of cell lines does not qualify for a biopatent.
