David Herzberg was alarmed when he heard that Richard Sackler, former chairman of opioid giant Purdue Pharma, was listed as an inventor on a new patent for an opioid addiction treatment.

Patent No. 9861628 is for a fast-dissolving wafer containing buprenorphine, a generic drug that has been around since the 1970s. Herzberg, a historian who focuses on the opioid epidemic and the history of prescription drugs, said he fears the patent could keep prices high and make it more difficult for poor addicts to get treatment. “It’s hard not to have that reaction of, like … these vultures,” said Herzberg, an associate professor at the University of Buffalo.

James P. Doyle, vice president and general counsel of Rhodes Pharmaceuticals, the Purdue subsidiary that holds the patent, said in an email statement that the company does not have a developed or approved product and “therefore no money has been made from this technology.”
