California

Life sciences focuses on the commercialisation of life sciences products (pharmaceuticals, medical devices and biotechnology programs etc). IP issues dominate as large pharmaceuticals seek to obtain innovative, impending blockbuster drugs from biotechs and other pharmaceutical companies. Also includes the licensing and acquisition of new products from other sources (often smaller biotechs to larger suppliers). This chapter includes advice on FDA issues and the increased focus on drug and device safety, which also appears in Healthcare.
