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.

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.

What Is an Inter Partes Review (IPR)?
An inter partes review of a patent is a type of administrative trial proceeding. Inter partes review became available in 2012 and replaced inter partes reexamination as a way to challenge patentability at the Patent Office. Any person who is not the owner of a patent can file a petition for a review of a patent. The Patent Trial and Appeal Board (PTAB) will act on the petition either instituting a trial or denying institution of a trial. This will occur a little over six months after the petition is filed. If trial is instituted, the proceeding will, with some limited exceptions, be resolved within one year.

What Is a Temporary Restraining Order (TRO)?
A temporary restraining order (TRO) is a legal document issued by a judge before trial that forces or prevents an action for a specified time frame. During court cases that involve trademark infringement or the use of a trade secret, a TRO can halt patent, copyright, or trademark infringement in the short term. It can offer relief in various situations, such as to prevent the sharing of a business secret or an unfair competition practice, until a court hearing on a preliminary injunction can be held. A TRO petition is an emergency request for a state or federal court to take immediate action based on submitted evidence.
