Experience Highlights: • Partnered with biotech start-ups to build IP portfolios, attract funding and negotiate strategic collaborations through strong IP positioning. • Guided life science and pharmaceutical companies through IP due diligence and multimillion-dollar licensing and acquisition deals. • Developed comprehensive antibody patent strategies that align with both scientific milestones and business objectives. • Managed the patent portfolio for a marketed ADC product.
