In a victory for biotechnology companies, a federal appeals court ruled Friday that human genes can be patented. Odds are pretty good the case will make its way to the Supreme Court, and it’s possible the justices will rule the other way, so this is not a done deal — but until then, it seems companies can own the exclusive right to use human genes.
The case involved patents on two human genes that are used to predict breast cancer, BRCA1 and BRCA2. To study these genes, patients and scientists will again have to pay a fee — up to $3,000 — to the company that owns the patent, Myriad Genetics.In a 2-1 ruling, the Court of Appeals for the Federal Circuit, which specializes in patent law, overturned an earlier decision that invalidated the patents. The decision is still somewhat unclear, however, with three separate opinions and a half-dozen points of law under debate. The lack of clarity, and the complex and controversial nature of the case, makes a hearing by the high court seem likely.
The court did rule against Myriad in one aspect, involving the process they use to analyze a patient’s genes. This requires “abstract mental steps,” the court said. So the court said the genes themselves could be patented, but a specific method of studying them could not.
"We strongly support the Court's decision that isolated DNA and cDNA are patent-eligible material as both are new chemical matter with important utilities which can only exist as the product of human ingenuity," said Peter Meldrum, president and CEO of Myriad Genetics. Scientists were not as pleased: "Genes or a sequence of the genome is a product of nature and should not be patentable," said Dr. Timothy J. O'Leary, president of the Association for Molecular Pathology, which brought the lawsuit.
The U.S. Trademark and Patent Office has already issued patents on more than 4,000 human genes, so a ruling that would invalidate gene patents would have major implications for the biotech industry. Companies like Myriad argue patents are necessary to protect product development and encourage innovation; opponents argue the ruling will stifle competitive research and jeopardize patient health, and that it’s unethical to patent something that comes from nature. The Obama administration had filed a brief arguing that isolated genes should not be patented.
Patents on plant and even animal genes have not risen to this level of controversy. Genetically altered plants and animals are big business for biotech firms, which license their gene patents to other companies that produce seeds, additives and other products. About 20 percent of the human genome is also patented, including genes associated with diseases like Alzheimer's. Other companies and researchers must pay fees to license the patent.
The court ruled that patents are allowed because once pieces of DNA are isolated from the body, their chemical structures differ from the DNA that exists inside the body — so they’re not actually products of nature. Two of the judges on the three-judge appellate panel are scientists, and brought their own analysis to the debate. Judge Alan D. Lourie, who as the Atlantic points out holds a PhD in chemistry, concluded thusly:
Judge Kimberly A. Moore, who has a degree in electrical engineering, also discussed the chemical makeup of the isolated DNA, but also said the new sequences have a utility that whole gene sequences do not — in this case, predicting breast cancer risk.
Judge William C. Bryson, who does not list any scientific background on his bio, was the sole dissenter, arguing that most people would argue patents are intended to protect inventions, and “a human gene is not an invention.”
Much legal wrangling remains to be done before this question is finally settled.
