United Therapeutics Corp. (UTHR: Quote) Thursday reported filing a lawsuit against Sandoz Inc. which seeks to block the approval of an Abbreviated New Drug Application, or ANDA, for the marketing of a generic version of United Therapeutics's product Remodulin.
Sandoz, a subsidiary of Novartis AG (NVS: Quote), claims in its ANDA that three US patents relating to Remodulin are "not valid, not enforceable" and cannot be infringed by production of a generic version.
Further, the US Food and Drug Administration, or FDA, is automatically precluded from approving the ANDA for up to 30 months as a result of the filing, which occurred within 45 days of Sandoz filing its application.
