In June the U.S. Supreme Court ruled that patents on genes were invalid. Yet corporate intellectual-property claims can still harm patients.

The court struck down patents held by Myriad Genetics on two human genes linked to breast and ovarian cancers, BRCA1 and BRCA2. The decision ended the company’s U.S. monopoly on testing those two genes for cancer-related mutations. But Myriad is now using a different tactic that restricts patient choice around genetic testing. The company has constructed a database of the genetic variants found in people who took its BRCA test. That unparalleled record of the natural variation in these important genes—collected from patients—is claimed to be Myriad’s own intellectual property.

Doctors can’t assess the significance of gene variants they find in their patients without free exchange of the kind of information held in Myriad’s database. It is as if patients’ radiological images were all examined by a single company that didn’t give the medical community a chance to learn from them.

Myriad’s database prevents patients from easily getting second opinions when they receive diagnoses based on BRCA tests. Patients...
