July 3, 2025 — Partners Michael N. Nemelka and Derek T. Ho of Kellogg, Hansen, Todd, Figel & Frederick, PLLC have been recognized among Bloomberg Law’s Unrivaled Litigators for 2025 in honor of the firm’s role as lead counsel in the groundbreaking antitrust class action Loop LLC v. CDK Global, LLC, No. 24-571 (W.D. Wis.). Representing a class of automotive software vendors, Michael Nemelka was lead counsel of a Kellogg Hansen team that included Derek Ho, Daniel Dorris, and Aaron Panner.  The case alleged a years-long antitrust conspiracy between CDK Global, LLC and The Reynolds & Reynolds Company – the two leading providers of dealer management system software – to restrict access to car dealership data.  As a result of the conspiracy, software vendors paid highly inflated prices for access to that data. On January 27, 2025, CDK agreed to pay $630 million to settle the claims, which is $140 million more than the class’s actual damages of $490 million.  That extraordinary result is a success story for private civil enforcement of our nation’s antitrust laws.  Without the aid of any government agency or prior action, the Kellogg Hansen team investigated the facts, discovered the alleged conspiracy, and pursued claims for the class for over seven years – from complaint through motion to dismiss, fact and expert discovery, Daubert and summary judgment, class certification, pretrial proceedings, and to the brink of trial. “This case required us to build the facts and legal theories from the ground up, and then the determination and energy to litigate the claims for over seven years from inception to the eve of trial,” said partner Michael Nemelka. “But with the team’s dedication and unrelenting efforts, we did it.  The strength of our evidence and our belief in the class’s claims carried us through.” In recognition of the remarkable result, Bloomberg Law named Michael Nemelka and Derek Ho to its inaugural list of Unrivaled Litigators featuring “trial lawyers who lead the legal profession in high-stakes and impactful trials and settlements.” To read more about the case and Bloomberg Law’s recognition of the firm, visit Bloomberg’s website.

June 13, 2025 — In his article \"Attorney-Client Privilege Versus the Right to Put On a Defense,\"  Bradley E. Oppenheimer, a partner at Kellogg Hansen, explores a critical legal tension: when a criminal defendant’s constitutional right to present a defense conflicts with a third party’s attorney-client privilege. The issue often arises in white-collar cases where corporate employees seek to raise an \"advice of counsel\" defense. However, since the corporation—not the individual—holds the privilege, it can block access to key legal communications. Brad examines current legal approaches and proposes a novel solution: using Federal Rule of Evidence 502(d) to allow limited disclosure of privileged communications without full waiver, preserving fairness for defendants while respecting corporate privilege. Read the full article on Westlaw, Lexis, or in the Document Library. Bradley E. Oppenheimer represents clients in high-stakes litigation and investigations, focusing on securities, FinTech and cryptocurrency litigation, False Claims Act proceedings, consumer protection, and complex commercial disputes.  He holds a track record of successful outcomes for both plaintiffs and defendants.

May 29, 2025 — In a resounding antitrust victory, a California federal jury awarded $147.4 million to Innovative Health LLC in its lawsuit against Biosense Webster Inc., a Johnson & Johnson subsidiary. Kellogg Hansen Todd Figel & Frederick PLLC led the case from opening statements to verdict. Kellogg Hansen entered the case as lead trial counsel in August 2024 after the Ninth Circuit Court of Appeals reversed a prior summary judgment in favor of Biosense Webster. That appellate decision revived Innovative’s claims and cleared the way for trial. At the center of the lawsuit were allegations that Biosense illegally tied its clinical support services to the purchase of its sensor-enabled cardiac mapping catheters, blocking hospitals from using FDA-cleared reprocessed alternatives. The case also focused on Biosense’s use of hardware-based blocking technology to exclude competitors like Innovative from the market. Kellogg Hansen’s trial team was led by partners Derek Ho and Andrew Goldsmith, who delivered the closing and opening statements, respectively, and examined key witnesses throughout the two-week trial. But the success was powered by a deep bench: all five Kellogg Hansen associates on the team, Rachel Anderson, Annamaria Morales-Kimball, Sean Quirk, Matthew Reade, and Kelley Schiffman also examined witnesses and argued evidentiary disputes to the court. Co-counsel Jeffrey L. Berhold of Jeffrey L. Berhold PC; Joshua P. Davis, Matthew Summers, and Kyla Gibboney of Berger Montague; and Panteha Abdollahi of Theodora Oringher also played important roles. The jury unanimously found that Biosense had violated federal and state antitrust laws, including the Sherman Act, by leveraging its dominance in clinical support to suppress lower-cost reprocessed catheters and maintain inflated prices. This case underscores Kellogg Hansen’s excellence in trial strategy and antitrust litigation. The outcome not only secures justice for Innovative Health, but it also sends a resounding message to dominant medical device firms: exclusionary tactics that block competition will not stand. This case has been highlighted in David Lat’s Original Jurisdiction and Law360 Legal Lions. Innovative Health LLC was represented by Derek T. Ho, Andrew E. Goldsmith, Rachel T. Anderson, Annamarie M. Morales-Kimball, Sean P. Quirk, Matthew D. Reade, and Kelley C. Schiffman of Kellogg Hansen Todd Figel & Frederick PLLC; Jeffrey L. Berhold of Jeffrey L. Berhold PC; Joshua P. Davis, Matthew Summers, and Kyla Gibboney of Berger Montague; and Panteha Abdollahi of Theodora Oringher. Innovative Health LLC v. Biosense Webster Inc., No. 8:19-cv-02148 (C.D. Cal.)..
