End of the Line: Winston Wins Unanimous Supreme Court Victory Against NJ Transit
In a unanimous decision authored by Justice Sotomayor, the U.S. Supreme Court held that NJ Transit is not an arm of the State of New Jersey and therefore is not entitled to sovereign immunity. The ruling means that plaintiffs injured by NJ Transit outside of New Jersey—such as in Pennsylvania and New York—may pursue claims in the courts of the states where their injuries occurred. The court adopted Winston’s position that state-created corporations that are formally liable for their own judgments are not arms of the state, reversing the Pennsylvania Supreme Court’s dismissal of Cedric Galette’s negligence suit while affirming the New York Court of Appeals’ decision allowing Jeffrey Colt’s case to proceed.

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.

Winston Secures Transformative Antitrust Verdict for States in Live Nation and Ticketmaster Trial
A Winston & Strawn team, led by Jeffrey Kessler, secured an antitrust verdict on behalf of more than 30 states and the District of Columbia, with a Manhattan federal jury finding Live Nation Entertainment and Ticketmaster liable for violating federal and state antitrust laws in a decision that has the potential to transform the concert, music, and ticketing industry. The jury concluded that Ticketmaster unlawfully maintained a monopoly in the primary ticketing market for major concert venues and that Live Nation unlawfully monopolized the large amphitheater market, compelling artists to use its promotion services to access its venues. Jurors further found that this conduct resulted in higher ticket fees, leading to an approximate $1.72 overcharge per ticket for consumers.

Federal contracts are the procurement mechanism the U.S. Government uses to obtain such goods, products, services, and property across all sectors and industries.

What Is the Federal Acquisition Regulation (FAR)?
The Federal Acquisition Regulation, commonly referred to as “FAR,” is a collection of regulations governing the process by which the federal government purchases products, supplies, and services. The FAR consists of 53 parts, each covering a different aspect of the government procurement process. FAR part 52, for example, provides solicitation provisions and clauses that can (and in some instances must) be inserted into contracts with the government. While the FAR applies to all executive agencies, many agencies, such as the Departments of Defense, State, and Veterans Affairs, have issued their own supplements to the FAR which provide regulatory guidance on contracting issues that are unique to them.

What Is the Patent Trial and Appeal Board?
The Patent Trial and Appeal Board (PTAB) is a tribunal within U.S. Patent and Trademark Office. The PTAB oversees trial proceedings, namely: inter partes review (IPR), post-grant review (PGR), covered business method (CBM) review, and derivation proceedings. The Board also hears appeals from adverse patentability decisions by patent examiners in original applications, reissues, and reexaminations. And, while phasing out since the passage of the America Invents Act (AIA) in 2011, the PTAB is also responsible for deciding interferences. The PTAB was previously referred to as the Board of Patent Appeals and Interferences and was renamed by the AIA.
