Epidiolex received authorization for use for the treatment of two rare forms of epilepsy in young children in 2018 and 2020 for the United States and in 2019 for Europe.

Apotex Inc, Padagis US LLC, InvaGen Pharmaceuticals, Inc, Cipla Ltd, Cipla USA, Inc, API Pharma Tech LLC, Lupine Ltd, Alkem Laboratories Ltd, Taro Pharmaceutical Industries Ltd. Ascent Pharmaceuticals, Inc., MSN Laboratories Private Ltd, MSN Pharmaceuticals, Inc, Zenara Pharma Private Ltd and Biophore Pharma, Inc.

The lawsuit was filed in the United States District Court for the District of New Jersey.

Larry Sandell, patent attorney at Mei & Mark LLP and head of the firm’s cannabis practice, told Marijuana Moment that ANDA patent cases of this type are relatively common in the pharmaceutical world, although they are somewhat unique here as they relate to cannabis products.
