Select Representations

Dr. Polizzi is patent counsel to numerous publicly traded and privately held companies, with many new client relationships resulting from her strong reputation in the life sciences industry. A selection of her representative matters include the following:

• Genentech, the world’s first and most successful biotechnology company, relies on Dr. Polizzi’s strategic patent counseling and prosecution services for its most difficult and challenging patent matters.

Her high-value work for Genentech also includes strategic assessment of key and novel technologies, as well as inter partes review and patent litigation support and advisement.


• Juno Therapeutics has continuously relied on Dr. Polizzi for patent strategy and prosecution. Juno is one of the best-funded start-ups in biotechnology history.

She led the IP team on the acquisition.


• Celgene calls on Dr. Polizzi for its patent strategy, drafting, and IP due diligence matters. She worked with Abraxis BioScience for many years in a similar capacity to help develop the IP position for the highly successful cancer drug, Abraxane. Dr. Polizzi then counseled the company through its $2.9 billion acquisition by Celgene Corporation, including providing significant IP strategy and due diligence counseling.
