Court Ruling

AstraZeneca PLC 17 November 2000 SWEDISH COURT RULES IN ASTRAZENECA'S FAVOUR IN OMEPRAZOLE SPC CASE AstraZeneca today announced that the Stockholm District Court has ruled that Scand Pharm's generic omeprazole product infringes AstraZeneca's Supplementary Patent Certificate (SPC) for omeprazole, which provides protection until 15 November 2002. Omeprazole is the active ingredient in 'Losec', a treatment for stomach acid disorders. The judgement follows an earlier preliminary injunction granted to AstraZeneca. Dr. Martin Nicklasson, Executive Vice-President of AstraZeneca's GI Franchise, said: 'We are delighted by this judgement, which confirms our opinion that the SPC for omeprazole is in force and prevents generic omeprazole products from entering the market.' In 1999, 'Losec MUPS' had sales of USD 90m in Sweden, representing 1.5 per cent of total sales of the product. The substance patent for omeprazole in Sweden expired in April, 1999. A decision is pending on AstraZeneca's appeal against a ruling by the Swedish Patent and Registration Office (PRV) that an SPC, granted under Swedish law, had lapsed due to the surrender of marketing authorisation for 'Losec' capsules. AstraZeneca has also filed a main action for infringement of the formulation patent for omeprazole against Scand Pharm. 17 November 2000 Further Enquiries to: Michael Olsson: Tel. +44 (0)20 7304 5087 Ed Seage: Tel. +44 (0)20 7304 5101 Jorgen Winroth: Tel. +1 609 896 4148
