In-person arguments resumed at the U.S. Court of Appeals for the Federal Circuit on Tuesday, with the court sounding poised to throw out a $1.2 billion judgment for a patent on a life-saving cancer treatment.

Chief Judge Kimberly Moore welcomed Orrick, Herrington & Sutcliffe partner Joshua Rosenkranz and Irell & Manella partner Morgan Chu back to Courtroom 201 at 10 a.m. “Good morning. This is very exciting for us,” Moore said. “We’re very excited to be back in person with you today.”
