Gold - Firms: litigation and transactions

“One of the best players on the market, ALTIUS is a leading IP litigation firm with an excellent track record in pharmaceutical cases.” A testament to this is its recent work on behalf of Eli Lilly in its dispute with Fresenius over a patent used in the treatment of certain cancers. The blockbuster product has been litigated all over Europe, and in Belgium market exclusivity was maintained until the patent expires. Christophe Ronse and Kirian Claeyé brought their A-game to the matter. “They are at the very top of their field and make an excellent team”, enthuses one peer. Ronse also comes in for additional praise: “A true gentleman and a star in the patent world, Christophe has been at the forefront of the practice for many years. He is an excellent lawyer who gets the best out of his opponents by forcing them to fight smart.” Working alongside them, Philippe de Jong is a compelling advocate and presents insightful and shrewd defence strategies that are backed by commercial and legal reasoning.
