Firm overview
Kirkland & Ellis LLP: Patent Litigation Summary
Firm Overview:
Kirkland & Ellis is a global "BigLaw" firm founded in Chicago in 1909. It has since expanded to approximately 22 offices worldwide and employs over 4,000 attorneys. Consistently ranked among the world's most elite and highest-grossing law firms, Kirkland & Ellis secured the top spot in The American Lawyer's 2024 Am Law 200 ranking with $7.2 billion in gross revenue. The firm holds Band 1 rankings from Chambers and Partners for its Intellectual Property practice, both nationally in the U.S. and in key jurisdictions.
IP Litigation Specialty:
The firm's patent litigation practice is known for handling complex, high-stakes "bet-the-company" cases across a wide spectrum of technologies. They have a particularly strong record in the life sciences and pharmaceuticals, litigating cases involving biologics, small molecules, and medical devices for major pharmaceutical companies. Additionally, the practice is a dominant force in technology and telecommunications, frequently representing clients in disputes over standard-essential patents (SEPs), semiconductors, and software. Their broad expertise is supported by a deep bench of trial lawyers with scientific and technical degrees.
Side Preference and Notable Cases:
Kirkland & Ellis represents a diverse client base on both the plaintiff and defendant sides in patent disputes. While the provided case list shows a plaintiff-side appearance for Atlas Global Technologies LLC, the firm is widely recognized for its defense work for major operating companies like Intel, Samsung, IBM, and Lenovo. For example, the firm secured a significant defense win for Samsung in a patent case related to its Bixby AI technology and represented Lenovo and Motorola Mobility in a major SEP licensing dispute.
PTAB / IPR Practice:
The firm possesses a leading Patent Trial and Appeal Board (PTAB) practice, handling a significant volume of inter partes review (IPR) and other post-grant proceedings. This practice is integrated with their district court and ITC litigation strategies. Managing Intellectual Property has repeatedly recognized Kirkland & Ellis for its national PTAB litigation practice.
Key Partners:
The firm's extensive intellectual property group includes numerous highly ranked attorneys. Among them are Gregory S. Arovas, noted for representing both plaintiffs and defendants in high-profile cases, and Dale Cendali, who chairs the copyright, trademark, and internet practice and is renowned for her work on landmark IP cases. Garret A. Leach, listed in the Atlas Global case, is a nationally recognized first-chair trial lawyer focusing on patent and IP litigation across various technologies.
