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

ESOP Class Claims Flop

After an eleven-day bench trial in January 2023, the N.D. Ill. delivered a full defense verdict in March 2025 in an ERISA class action brought by participants in Segerdahl Corporation’s ESOP. The court rejected the class claims against Segerdahl, its ESOP trustee GreatBanc Trust Company, and various individual defendants including board members Bob Cronin, Rod Goldstein, and Peter Mason, alleging that Segerdahl could have sold for a significantly higher price, which would have increased post-sale distributions to the ESOP participants. Winston earned an Am Law Litigator of the Week Shout Out for this win....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.

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....Read more
