Supreme Court Strikes Down BRCA Gene Patent
Court rules unanimously that Myriad Genetics "did not create anything."
June 13, 2013 -- The Supreme Court ruled today that isolated human genes cannot be patented, a partial defeat for Myriad Genetics, a company that had been awarded patents on the so-called BRCA1 and BRCA2 genes in the 1990s.
But the court said DNA molecules engineered by man -- including so-called "cDNAs" -- are eligible for patents.
"Myriad did not create anything," Justice Clarence Thomas wrote for a unanimous court.
"To be sure, it found an important and useful gene, but separating that gene from its surrounding genetic material is not an act of invention."
Synthetic "cDNA" does not present the same obstacles to patentability as naturally occurring isolated DNA segments, Thomas wrote.
Myriad acknowledged the court's ruling that five of its claims covering isolated DNA were not patent eligible. But Myriad "has more than 500 valid and enforceable claims in 24 different patents conferring strong patent protection for its BRACAnalysis test," the Salt Lake City, Utah-based company said in a statement today.
The court today adopted a middle-ground position that the U.S. government had put forward.
"Today, the court struck down a major barrier to patient care and medical innovation," said Sandra Park, senior staff attorney with Women's Rights Project of the American Civil Liberties Union, which had challenged the patents.
"Myriad did not invent the BRCA genes and should not control them. Because of this ruling, patients will have greater access to genetic testing and scientists can engage in research on these genes without fear of being sued."
Women with mutations in the genes BRCA1 or BRCA2 are five times more likely to be diagnosed with breast cancer, according to the National Cancer Institute. That means that 60 percent of women with a BRCA mutation will develop breast cancer in their lifetime, compared to 12 percent of women in the general population.
But less than 1 percent of women actually have a BRCA mutation, making costly genetic testing unnecessary for most.

The American Medical Assocation said it welcomed the ruling.
"The U.S. Supreme Court's unanimous rejection of patenting human genes is a clear victory for patients that will expand medical discovery and preserve access to innovative diagnosis and treatment options," the AMA said in a statement today.
Biotechnology companies, racing to create personalized tests and treatments tailored to a person's genetic makeup, were closely watching this case.
Professor Lori Andrews of the Illinois Institute of Technology Chicago-Kent College of Law said, "Today's decision allows any doctor or scientist to use the breast cancer gene for diagnosis or treatment. This means all genetic tests will become affordable and more researchers will be able to look for cures."
Andrews filed a brief opposing Myriad's patent but says that biotechnology companies will be adequately protected if they genetically engineer a product.
The challenge to Myriad's patents was brought by scientists, researchers and patients who believed that the patents stood in the way of further research on the genes and limit the availability testing. The ACLU represented the groups in court and argued the court should invalidate the patents because they cover a product of nature and not an actual invention.
Because of the patents, Myriad is the only place in the United States to go for diagnostic testing at a $3,340 price tag.
Myriad's lawyers had fiercely defended its patents, arguing that they have been essential to the development of diagnostic tools to help patients and doctors assess the risks of cancer.
