Cadwalader Intellectual Property Group chair Dr. Dorothy Auth last week participated in a program hosted by the International Intellectual Property Law Association (IIPLA), titled “Navigating the Intersection between Patent Prosecution and Patent Litigation,” that addressed patent eligibility from both the life sciences and high-tech perspectives as well as prosecution history estoppel as issues affecting litigation.
The hybrid event, which took place both virtually and live in Las Vegas, gathered IP industry practitioners and professionals from all over the world to discuss the latest topics and trends in the IP industry.
Auth was joined on her panel by Samantak Ghosh, senior counsel (IP) at Gilead Sciences; Curtis Smolar, general counsel at Legalist; Thomas Rössler, patent attorney at LUXPATENT Intellectual Property; and Michael Rueckheim, a partner at Winston & Strawn.

The panel addressed other topical issues, including:
Auth has 30 years of experience in coordinating global IP enforcement, licensing and procurement strategies for clients in diverse industries, including biotechnology, pharmaceutical, and medical devices, as well as consumer products, computers and financial services.
