Lawyer Rankings

United States > Intellectual property > Patents: litigation (full coverage)

Kirkland & Ellis LLP impresses with its successful track record before all major patent litigation venues in the US, including the PTAB and the ITC. The practice stands out through its commitment to preparing every case for trial, drawing on its excellent bench of senior and junior litigators with experience in a wide spread of technologies thanks to a team consisting to three quarters of practitioners with a science or engineering background. Major domestic and, increasingly, international clients entrust their complex high-stakes disputes to the team, including several pharma giants, global telecommunications and consumer product companies, blue chip technology and electronics players as well as food and beverage multinationals. Gregory ArovasJeanne Heffernan, Todd FriedmanJoseph LoyJames McConnell and Robert Appleby in New York, Adam Alper in San Francisco, Michael De Vries in Los Angeles, John O’Quinn and Jason Wilcox in Washington DC and Chicago trio Amanda Hollis, James Hurst and Gianni Cutri are key names in the practice. In Ellisen Shelton Turner, who arrived from Irell & Manella LLP in September 2019, the firm gained one of the country’s finest patent and trade secret litigators. In summer 2019, Sarah Piepmeier joined Perkins Coie LLP and Kenneth Adamo left to open an independent practice.

United States > Dispute resolution > Appellate: courts of appeals / Appellate: supreme courts (states and federal)

Kirkland & Ellis LLP has a premier appellate law practice that is known for its involvement in disputes with significance in the wider market. Indeed, the team is rated clients for its ‘deep knowledge of the direction of the courts on the most significant legal issues of the day’. Constitutional law cases are a forte of the group, and an area for which it is recommended by peers and clients alike. Building upon Erin Murphy’s success in Gill v Whitford in 2018, Paul Clement successfully argued in favor of North Carolina’s legislature, as appellant, in Rucho v Common Cause, a closely watched partisan gerrymandering case at the US Supreme Court. The group also acted for the petitioners in New York State Rifle & Pistol Association Inc. v City of New York, New York, the highly anticipated Second Amendment case challenging New York City’s restriction on the transport of guns, which the US Supreme Court recently remanded to the Second Circuit. Clearly, the firm is extremely active in the US Supreme Court – in the 2019 term, the team was scheduled to present arguments in seven cases. Clement in particular, a former US Solicitor General, has more than 100 US Supreme Court arguments under his belt. One more SCOTUS highlight from the past year was George Hicks‘ victory for a Crow tribe member in Herrera v Wyoming, a case in which the Court declared that Wyoming’s statehood did not abrogate the tribe’s right to hunt, confirmed under an 1868 federal treaty. The group is also standout on the courts of appeals front as well. John O’Quinn has extensive experience in IP cases tried at the Federal Circuit, and New York-based Jay Lefkowitz is a go-to contact for shareholder, antitrust, and product liability disputes. In addition, thanks to its full integration in the firm’s wider litigation group, the appellate practice routinely works with the firm’s trial lawyers, particularly in the area of mass torts.
