Tandem Diabetes Care and Roche remain entangled in a patent dispute without a settlement in sight as of May 25, 2025. The legal battle centers around Roche's infringement claims that Tandem's t:slim X2 insulin pump violates their EP Patent No. 1 970 677 B1. Initially, Roche took the issue to the Unified Patent Court in Düsseldorf, Germany, in December 2023, demanding damages and halting Tandem's alleged infringement activities.
Supporting developments saw an April 2025 hearing at the UPC Düsseldorf, where Tandem countered with claims of non-infringement and argued for patent claim revocation. According to streetinsider.com, the court looked at both sides' arguments earlier this year, with a decision anticipated on May 22, 2025.
Despite these proceedings, there is no confirmation of an agreement or settlement between the companies. As the industry watches closely, statements from either company remain sparse, focusing more on addressing procedural aspects rather than any potential reconciliation or strategy-related announcements.
