about against

A man named Salvador Dolly gives blood for a routine genetic test to determine his fitness to father a child. The testing company, Advanced Genetic Testing Company (AGTC), then sells the remains of the sample to NuGenEra, a biotechnology company. NuGenEra discovers that Dolly's genes make him resistant to HIV.

The company responds to this discovery by taking out a patent on both Dolly's genome and a series of gene sequences that confer resistance. When NuGen-Era informs Dolly that his genes guard against the deadly virus, he decides to set up a business to market his blood to research institutions. To protect its patent, NuGenEra sues Dolly for patent infringement, saying that it owns his genome.

Does the patent mean that Dolly must forgo any rights to his own genome? Does it violate his privacy or property rights? Should these rights be balanced against society's need for the tests and therapies for HIV that might be derived from NuGenEra's research on Dolly's genome?


Could you tell me which one is right? Thanks.
