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.

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.

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 the Copyright Royalty Board?
The U.S. Copyright Royalty Board (CRB) is a three-judge panel that functions as an independent unit within the Library of Congress. It performs the duties specified in the Copyright Royalty and Distribution Reform Act. The Act established statutory licenses that let approved parties utilize certain types of copyrighted works by paying a set royalty, without having to request an individual copyright license from each rights-holder. The CRB sets, and periodically adjusts, the rates and terms of the statutory licenses, and can also make determinations on the distribution of statutory license royalties collected by the U.S. Copyright Office. For example, the judges can determine, for a five-year period, the rates musical performers receive when their works are played via digital services. When licensors and licensees cannot reach rate agreements on their own, the CRB hears testimony from the various parties and then sets the rates. CRB Judges serve six-year terms. The first CRB judges were appointed by the Librarian of Congress in 2006.
