Demonstrating a marked focus on IP-related appeals, satisfied clients of Kirkland & Ellis LLP praise the team as the ‘best in the business’. The firm has a strong presence before the Federal Circuit, which hears federal cases involving patents and trademark registrations, among other specialist issues. Key contact John O’Quinn, who is based in Washington DC, is particularly recommended for IP and regulatory appeals and has argued more than fifty patent appeals in the Federal Circuit. O’Quinn recently teamed up with the IP practice to secure three wins for Intel in the Federal Circuit with the reversal of three unfavorable Patent Trial and Appeal Board rulings. The department also draws on George Hicks, who splits his time between Washington DC and Dallas; New York’s Jay Lefkowitz, who is noted for his record in the life sciences sphere; and Washington DC-based William Burgess.
