PT. SEG Solar Manufaktur Indonesia appears as a plaintiff in one tracked case at the Patent Trial and Appeal Board (PTAB): SEG Manufacturing Inc. et al. v. Zhejiang Jinko Solar Co Ltd et al., filed on February 18, 2026. This indicates an active posture in asserting its intellectual property, specifically within the realm of patent challenges at the PTAB. The presence of its parent company, SEG Manufacturing Inc., as a co-plaintiff suggests a coordinated effort in patent enforcement.
