Detailed Summary

In Petition IPR2025-00747, Decent Espresso International Ltd. challenges claims 1‑10 of U.S. Patent 11,957,271, which covers an electro‑mechanical coffee‑brewing device. The petitioner relies on a portfolio of prior‑art patents and publications—including Startz, Coccia, Buttiker, Majer, Porzio, and Giuliano—to argue that each claim is either anticipated or obvious under 35 U.S.C. §§ 102 and 103. Detailed claim‑by‑claim analysis is provided, along with expert testimony from former Keurig engineer Ian Tinkler. The petition also addresses discretionary factors, noting parallel district‑court litigation and a Sotra stipulation, and requests that the Board institute the review to cancel the patent claims.
