UK – LEO Pharma v. Sandoz Limited / First instance
Posted: May 15th, 2009
LEO Pharma A/S and LEO Laboratories Limited v. Sandoz Limited, invalidity proceedings, High Court of Justice, Chancery Division, Patents Court, UK, 15 May 2009, Docket No. HC08C00391, with thanks to Marc Döring and Rowan Freeland, Simmons & Simmons
Sandoz unsuccessfully challenges Leo's patent on the basis that the claimed invasion is anticipated by and/or it is obvious in light of an earlier LEO patent application. None of the claims of the patent (for a new crystalline form of calcipotriol, calcipotriol monohydrate, used in the treatment of psoriasis) was found to be invalid. The infringement claim had been admitted by the defendant on the eve of trial and the counterclaim for revocation was dismissed.
