Alvogen conceded infringement of all claims at issue in the litigation, and accordingly, Collegium expects that, by virtue of the Federal Circuit’s decision, Alvogen will be barred from entering the market with its product until 2032.

“We are very pleased with the Federal Circuit’s decision, which reinforces the strength of the patents supporting Belbuca, and we look forward to continuing to supply this innovative and differentiated product to appropriate patients,” said Shirley Kuhlmann, General Counsel and Chief Administrative Officer of Collegium.
