The United States International Trade Commission (ITC) is an increasingly popular venue for patent infringement litigation. More and more companies are seeking to halt importations of infringing products into the United States by turning to the ITC for expedited relief. Section 337 investigations conducted by the ITC provide complainants with a “fast track” to remedy IP matters that typically go to trial within 10 months. Since many Section 337 cases go to trial, selecting an ITC litigation team with a command of the technology, patent law, and specialized procedural practice is extremely important. We have handled more than 100 cases before the ITC.

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.

Law Glossary
Colloquially referred to as the “patent dance,” the BPCIA provides a framework that includes certain steps and a schedule during which the applicant and reference product sponsor exchange confidential information disclosed in the aBLA. During the patent dance, the applicant and sponsor identify the patents that could be litigated in the future during two potential phases of litigation. In the first phase, the sponsor can allege infringement of a subset of the patents identified during the patent dance. The second phase begins after the sponsor receives the Notice of Commercial Marketing from the applicant. During this second phase, the sponsor can assert any remaining patents that were not asserted in the first phase.

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.
