Winston Wins Ninth Circuit Reversal and Class Certification in Swimmers’ Antitrust Case, Securing a Global-Impact Settlement with World Aquatics

Winston represents a class of professional swimmers alleging World Aquatics (WA) violated antitrust laws by blocking their participation in the competing  International Swimming League. After WA won summary judgment, Winston successfully appealed, arguing the court applied improper antitrust standards and wrongly denied certification of a damages class. In September 2024, the Ninth Circuit reversed both rulings, reviving all claims and issuing a landmark ruling on the possible application of the per se rule or quick look review to sports-associations rules. Am Law awarded Winston “Litigator of the Week” Runner-Up recognition for the win. In November 2024, the Ninth Circuit denied rehearing. In April 2025, the district court certified a damages class....Read more

Winston Secures Federal Circuit Victory for Snap Axing Image-Presentation Patents on the Pleadings

Ask Sydney sued Snap along with four large tech companies in the Western District of Texas, Waco Division, asserting infringement of two related patents on methods of generating and presenting images to a user to determine the user’s interest.  Working closely with Snap, Winston successfully moved to transfer the case to the Central District of California, then moved for judgment on the pleadings of patent-ineligibility under § 101 of the Patent Act.  Following a hearing with multiple rounds of argument, the district court granted the motion, adopting Winston’s arguments that distinguished findings by the patent examiner during prosecution and by the Western District of Texas, which had denied § 101 motions brought by two other defendants.  Ask Sydney appealed, but the Federal Circuit summarily affirmed three days after oral argument, handing Snap a decisive win invalidating all claims of both asserted patents. Eimeric Reig led the strategy and argued the appeal and motion hearing, working with Kathi Vidal and Kelly Hunsaker....Read more

Court Ruling Curtails Administration’s Ability to Terminate Grants Based on New Priorities

On March 24, 2026, the U.S. District Court for the Northern District of Illinois decided that federal grantees can challenge grant terminations by the Administration if at the time of termination the grantees were compliant with Administration policies that were in place at the time the grant was awarded, as opposed to new rules or policies subsequently imposed by the Trump Administration. This decision could aid federal contractors and grantees in their legal challenges to the numerous contract and grant terminations, which have occurred since January 2025, based on alleged failure of the contracts or grants to align with or effectuate new Administration programs, policies, goals, and/or priorities, including, but not limited to, those relating to diversity, equity and inclusion (DEI) programs and policies.
