to as "Dr. Reddy's") announced today that the United States Court of Appeals for the Federal Circuit issued a
decision in favor of Dr. Reddy's Laboratories Inc., concluding that Indivior had not shown that it is likely to succeed on
the merits of its infringement case on U.S. Patent No. 9,931,305. This decision vacates the District Court's preliminary

the unmet and under-met needs of patients around the world and in particular look forward to taking the lead in helping to fight
Opioid Use Disorder."
