Samsung Display Co., Ltd. et al. v.Pictiva Displays International Ltd. et al.
Samsung Display successfully secured the institution of its IPR against Pictiva Displays regarding key claims of a passive electronic component patent.

Samsung Display Co., Ltd. et al. v.Pictiva Displays International Ltd. et al.
The PTAB found several claims of the patent unpatentable over prior art references Ingle and Hasei. The Board adopted a narrow claim construction for 'a first trench,' requiring adjacency to conductive layer edges. This decision significantly reduces the scope of the asserted claims in OLED manufacturing technology.

Samsung Display Co., Ltd. et al. v.Pictiva Displays International Ltd.
Samsung Display Co., Ltd.'s IPR petition against Pictiva Displays International Ltd. was denied by the PTAB. The Board found that the petition lacked compelling merits and determined the dispute was better suited for District Court resolution due to complex claim construction issues.
