A gene patent gives its owner the exclusive right, for up to 20 years, to control its use for medical research, diagnosis or treatment.

"A gene patent holder has the right to prevent anyone from studying, testing or even looking at a gene,'' the ACLU lawsuit protests. "As a result, scientific research and genetic testing has been delayed, limited or even shut down due to concerns about gene patents.''

Patent holders reply that they have a constitutionally guaranteed right to protect their inventions in order to pay the heavy costs...
