WASHINGTON – Several Supreme Court justices sought a compromise on the decades-old practice of granting patents on human genes, debating a case that could redefine rights throughout the biotechnology and agricultural industries.
Hearing arguments Monday in Washington, the justices discussed chocolate-chip cookie recipes, baseball bats and Amazonian plants as they grappled with a challenge to Myriad.
Genetics Inc.s patents on genes linked to breast and ovarian cancer. A group of doctors, patients and scientists say the patents are stifling clinical testing and research.
Several justices asked whether barring gene patents would deter innovation by stripping companies of legal protection for their research.
Without a patent, what does Myriad get out of this deal? Justice Elena Kagan asked. Why shouldnt we worry that Myriad or companies like it will just say, well, you know, were not going to do this work any more?
The case has implications for the growing field of personalized medicine as well as efforts to map the human brain and discover new uses for embryonic stem cells. It could also ripple well beyond medicine. Agricultural companies, including Monsanto Co., inject genes into seeds, and industrial microbiology businesses use micro-organism DNA to improve biofuel manufacturing.
Justices Sonia Sotomayor, Stephen Breyer and Anthony Kennedy all asked about a middle ground that had been suggested by the Obama administration. The government says the court should void parts of Myriads patents while leaving open the possibility that other aspects will be upheld.
The administration says Myriad isnt entitled to a patent on isolated DNA, which the government says is merely a snippet of the genetic sequence as it appears in the body. The administration says Myriad might be entitled to a patent on so-called complementary DNA, which involves a greater level of human manipulation.
Kennedy asked Myriads lawyer whether that approach would give the industry sufficient protection for innovation and research.
Complementary DNA, also known as cDNA, is a stripped-down version of the genetic sequence within the body, separating out the portion of the gene that can encode proteins.
Complementary DNA is not a product of nature, Sotomayor said. Its a product of human innovation.
At the same time, Sotomayor signaled skepticism about patents on isolated DNA. She likened genetic sequences to the ingredients for chocolate-chip cookies.
I cant imagine getting a patent simply on the basic items of salt, flour and eggs, simply because Ive created a new use or a new product from those ingredients, Sotomayor said.
Myriads lawyer, Gregory Castanias, said isolated DNA was more akin to a baseball bat carved from a tree. He said isolated DNA and the bat both are patentable because they require humans to make important decisions about exactly where to cut.
A baseball bat doesnt exist until its isolated from a tree, he said. But thats still the product of human invention to decide where to begin the bat and where to end the bat.
The administrations stance marks a rejection of the longstanding policy of the U.S. Patent and Trademark Office, which has awarded human gene patents since 1982.
Patient advocates accuse Myriad of standing in the way of breast cancer diagnosis and treatment. The company at one point demanded that the University of Pennsylvania stop clinical testing of cancer patients.
Critics say Myriads patents effectively give the company ownership rights over a part of the human body. Myriad says its patents havent prevented researchers from publishing thousands of papers on the genes.
