In December 2022, Winston convinced Judge Albright of the W.D. Tex. to reverse his tentative construction and invalidate four patents based on means-plus-function indefiniteness at claim construction in the district court. Winston also persuaded Judge Albright to deny Fintiv’s motion for reconsideration the next month. Fintiv appealed to the Federal Circuit, which affirmed the district court in a precedential opinion in April 2025. Winston overcame a significant amount of sleight of hand from Fintiv, which continually shifted the purported structure of the “payment handler” term through claim construction, its motion for reconsideration, and appellate briefs, muddying the record. Ultimately the opinion clearly distinguished the factual record from that in Dyfan v. Target, curbing patentees abilities to argue that all code or applications are a “class of structures” and not indefinite under 112(f). The Federal Circuit affirmed four of the five patents Winston invalidated for PayPal, effectively foreclosing Fintiv’s ability to revive these patents for assertion. Winston also invalidated the fifth patent at the PTAB; Fintiv’s appeal of that Final Written Decision is pending.

After an eleven-day bench trial in January 2023, the N.D. Ill. delivered a full defense verdict in March 2025 in an ERISA class action brought by participants in Segerdahl Corporation’s ESOP. The court rejected the class claims against Segerdahl, its ESOP trustee GreatBanc Trust Company, and various individual defendants including board members Bob Cronin, Rod Goldstein, and Peter Mason, alleging that Segerdahl could have sold for a significantly higher price, which would have increased post-sale distributions to the ESOP participants. Winston earned an Am Law Litigator of the Week Shout Out for this win.

What Is Advertising Litigation?
Advertising litigation is defined as the legal area that covers false or deceptive advertising cases. Lawsuits may be brought by government agencies or corporate competitors based on the Lanham Act—a law that specifically deals with false advertising. The Act outlines how an advertisement can be deemed false. The Federal Trade Commission (FTC) has the ability to file lawsuits to halt deceptive advertising claims. The U.S. Food and Drug Administration may also pursue advertising litigation against violators of government regulations. Companies may be called on to substantiate their advertising claims, whether these are made in print or online.
