Patent Litigation

Failed Operating Company CEO v. Leading Technology Company
We successfully defended a network technology leader in this patent infringement case filed in 2018 by the named inventor and former CEO of a failed operating company. After we persuaded the Eastern District of Virginia to dismiss the plaintiff’s pre-suit claims for willful infringement, the plaintiff dismissed one of its two patents. At the claim construction stage, we persuaded the court that all claims of the remaining patent were invalid for indefiniteness. On appeal in 2020, the Federal Circuit affirmed. Ms. Brannen served as lead trial and appellate counsel.

In 2020, we persuaded the District of Delaware to grant our motion for judgment on the pleadings, holding all claims of a multi-factor authentication patent ineligible for patenting.
