Program Materials

This CLE webinar will provide patent counsel with guidance on the use of invalidity opinions in defense of patent infringement claims. The panel will discuss the issue of waiver of the attorney-client privilege and other factors when considering invalidity opinions. The panel will provide best practices for obtaining and using invalidity opinions.

Description

Recent decisions, including Halo Electronics Inc. v. Pulse Electronics (U.S. 2016), have changed the landscape and renewed awareness of the role an invalidity opinion can play in patent litigation. Obtaining an invalidity opinion and examining infringement risks can protect an accused infringer from a willful infringement finding and significant damages.

However, obtaining and utilizing invalidity opinions is not without its risks. The alleged infringer should consider the timing as well as the potential steps that could be triggered by an invalidity opinion. Further, a price for using an invalidity opinion could be a waiver of attorney-client privilege.

Listen as our authoritative panel of patent attorneys examines the use of invalidity opinions and the considerations counsel must address when drafting an invalidity opinion. The panel will also offer best practices for using invalidity opinions.
