Robins Kaplan Secures Trial Victory in Patent Infringement Case For Client ionLake

May 5, 2023

Robins Kaplan LLP is pleased to announce that on May 4, 2023, a Minnesota federal jury issued a complete defense verdict in favor of our client ionLake, LLC, affirming that the company did not infringe plaintiff CellTrust’s patents and that both CellTrust patents at issue in the lawsuit were invalid.

The case dates back to 2019 when CellTrust sued ionLake for patent infringement related to ionLakes’s MyRepChat product. That product, a SMS communication platform, was created to address security and compliance issues in client communications. In its lawsuit, CellTrust argued its patents covered products that send SMS/MMS/Voice communications to archivers to meet FINRA/SEC compliance requirements. After an eight-day trial and only two hours of deliberations, the jury found that ionLake did not infringe any of CellTrust’s patents and that all the asserted claims in CellTrust’s patents were invalid.

“ionLake is grateful for the jury’s thoughtful attention to this case,” said lead trial counsel Patrick Arenz. “The verdict fully vindicates what ionLake has maintained throughout the litigation: CellTrust’s patents are invalid and ionLake doesn’t infringe them either. Robins Kaplan was retained less than two months before trial. It was an honor to represent ionLake and its founders, and to deliver this well-deserved result for them.” 

Partner Emily Niles adds, “ionLake is a proven innovator with its MyRepChat product. It was a privilege to secure a result at trial that recognizes that conclusion.”

The trial team included partners Patrick Arenz and Emily Niles, and associate Austin Miller.
