Todd J. Ohlms

Todd J. Ohlms is a Partner in the Litigation Department at Proskauer Rose LLP, where he has practiced since December 2020. Prior to joining Proskauer, he spent 25 years at Freeborn & Peters LLP, serving as a Partner and Co-Chair of their Private Equity/Portfolio Company and Litigation Practice Groups. Based in Chicago, his broader practice encompasses business-critical litigation matters, with substantial experience in intellectual property, antitrust, trade regulation, securities, and shareholder litigation.

In the realm of patent litigation, Mr. Ohlms has experience representing both plaintiffs and defendants. His tracked appearances include representing Haemonetics Corporation as a plaintiff in two instances, and also as a defendant once, in the case Haemonetics Corporation v. Fresenius Kabi USA, LLC et al.. This particular case, filed in the U.S. District Court for the Northern District of Illinois in 2025, involves patent infringement within the mechanical engineering and manufacturing sector, specifically concerning medical technology. The case remains open as of early 2026, with no publicly available outcomes such as verdicts or appeals yet reported.

While his general litigation profile is extensive, involving a significant focus on disputes related to private investment funds, direct evidence of his regular involvement in Patent Trial and Appeal Board (PTAB) or Inter Partes Review (IPR) proceedings was not found in publicly available information.

Mr. Ohlms is admitted to practice in Illinois. He earned his J.D. from Washington University School of Law and holds a B.S. in Aerospace Engineering from the University of Missouri – Rolla (now Missouri University of Science and Technology). He also attended the United States Air Force Academy.
