Bayer Pharma Aktiengesellschaft and Bayer Australia Ltd had filed a patent infringement lawsuit against Generic Health Pty Ltd and Lupin Australia Pty Ltd, subsidiaries of the company, in the Federal Court of Australia, Lupin said in a filing to BSE.
The Bayer arms had alleged that sale of tablets by Lupin, containing Drospirenone 3 mg and Ethinyl Estradiol 30 microgram under the brand name 'Isabelle' infringed their Australian patent.
"We are in the process of reviewing the Judge's reasons for judgement and deciding next steps," Lupin said.
