Federal Circuit reverses Insulet trade secret ruling against EOFlow

EOFlow said the U.S. Court of Appeals for the Federal Circuit has issued its mandate after reversing a district court judgment on Insulet’s trade secret claim. The ruling ends a major litigation chapter for the South Korean insulin delivery company as it looks to refocus on growth and global expansion.

Why it matters: - The Federal Circuit ruling removes a major legal overhang for EOFlow after more than three years of litigation. - The court’s decision also awarded appeal costs to EOFlow. - The outcome may help EOFlow shift attention back to product development and international expansion.

What happened: - EOFlow announced that the United States Court of Appeals for the Federal Circuit issued its mandate on October 29, 2026. - The mandate followed the court’s October 19 denial of Insulet Corporation’s requests for panel rehearing and rehearing en banc. - The court also denied Insulet’s October 22 request to stay issuance of the mandate and ordered the mandate to issue immediately. - The Federal Circuit had already reversed the district court’s judgment on May 28, 2026 in Insulet Corp. v. EOFlow, Co. Ltd., et al. - The case arose from the United States District Court for the District of Massachusetts, Case No. 1:23-cv-11780-FDS, before Judge F. Dennis Saylor IV. - EOFlow said the appeal involved Insulet’s trade secret claim against EOFlow, its U.S. subsidiary, and EOFlow founder and CEO Jesse J. Kim.

The details: - The Federal Circuit concluded that the statute of limitations had expired before Insulet filed its lawsuit in August 2023. - EOFlow said the company is a developer of disposable wearable insulin delivery technology. - EOFlow develops wearable drug delivery solutions, including EOPatch, a wearable insulin patch pump designed to support people living with diabetes. - EOFlow said the company is committed to advancing technologies that make drug delivery more convenient and accessible. - EOFlow is represented by Cooley LLP in the case. - Media contact information listed Jesse Kim as CEO, along with EOFlow’s phone number and email address. - Legal counsel contact information listed Sale Kwon, partner at Cooley LLP, with email and phone details. - EOFlow provided a Facebook link: More information.

Between the lines: - Jesse J. Kim described the case as one of the most challenging chapters in EOFlow’s history. - Kim said employees, shareholders and partners supported EOFlow through prolonged litigation and financial difficulties. - Kim also said the market is undergoing a substantial transformation driven by technological advances, and EOFlow is well positioned to benefit from that shift. - The language suggests EOFlow wants investors and partners to see the ruling as a turning point, not just a legal win.

What’s next: - EOFlow is positioning itself to focus on regrowth and global expansion after the appellate mandate. - The company is likely to use the ruling to reduce uncertainty around its business outlook. - The litigation itself appears to be functionally resolved unless new legal steps emerge.
