Litigation Status

As of April 30, 2026, a comprehensive search of United States federal court dockets, including the Public Access to Court Electronic Records (PACER) system, the U.S. Court of Appeals for the Federal Circuit (CAFC) case listings, and specialized patent litigation databases such as Unified Patents, reveals no known litigation involving US patent 12347711.

While there is no litigation in the U.S. concerning this specific patent, it is worth noting that the assignee, Gudeng Precision Industrial Co., Ltd., has been involved in other patent disputes, particularly with Entegris, Inc. These lawsuits, which have taken place in Taiwan, have concerned different patents related to semiconductor wafer and reticle carriers, including Front-Opening Unified Pods (FOUPs). These past cases do not have a direct legal bearing on US patent 12347711 but indicate that the patent holder is active in enforcing its intellectual property rights in the semiconductor carrier market.
