Christian O. Nagler

Christian O. Nagler has one recorded appearance in patent litigation, serving as counsel for the defendant in Greenthread, LLC v. OSRAM GmbH. This case involved allegations of patent infringement related to semiconductor devices with graded dopant regions.

However, public professional profiles for a Christian O. Nagler, a partner at Kirkland & Ellis, overwhelmingly describe a practice focused on Capital Markets, Mergers & Acquisitions, and general transactional law. These profiles consistently highlight his work with securities transactions, special purpose acquisition companies (SPACs), and FinTech, explicitly noting his inclination for transactional law over litigation. Given this extensive public information, it appears that patent litigation is not a primary focus of his practice, or the authoritative case entry may refer to a different attorney with the same name.

Assuming the authoritative case entry refers to the same individual, his single tracked patent litigation appearance was on the defendant side, representing an operating company against patent infringement claims. There is no publicly available information to suggest a regular practice in IPR or PTAB proceedings for this attorney, nor any notable trial results or publications specifically pertaining to patent litigation.

Christian O. Nagler is a partner at Kirkland & Ellis LLP. He earned his J.D. from Cornell University Law School in 1997 and a B.A. from Skidmore College in 1992. He was admitted to practice in New York in 1998 and Connecticut in 1997.
