The U.S. Patent Trial and Appeal Board (PTAB) has invalidated two patents held by Pictiva Displays International Ltd., including one that accounted for $92.6 million of a $191.4 million infringement verdict against Samsung Electronics Co., Ltd. This decision significantly impacts the financial and legal landscape of the ongoing dispute between the two companies.
In November 2025, a jury in the Eastern District of Texas found that Samsung had willfully infringed Pictiva’s U.S. Patent Nos. 8,314,547 and 7,446,425, both related to organic light-emitting diode (OLED) display technologies. The jury awarded Pictiva $191.4 million in damages, with the ‘547 patent alone accounting for $92.6 million of the total award.

Following the verdict, Samsung petitioned the PTAB for inter partes review (IPR) of the two patents. The PTAB’s recent decision invalidated both patents, effectively nullifying the basis for the substantial portion of the damages awarded to Pictiva. This outcome underscores the strategic importance of PTAB proceedings in patent litigation, particularly in high-stakes cases involving significant financial awards.
The PTAB’s ruling is expected to influence the trajectory of the ongoing litigation between Pictiva and Samsung. While the jury’s verdict had initially favored Pictiva, the invalidation of the patents in question may lead to a reassessment of the damages awarded and could potentially alter the course of any appeals or settlement discussions.
This case highlights the complex interplay between district court litigation and PTAB proceedings in the U.S. patent system. Companies involved in patent disputes must navigate both arenas effectively, as outcomes in one can substantially impact the other. The PTAB’s decision to invalidate patents that formed the cornerstone of a significant jury award demonstrates the critical role of post-grant reviews in shaping the resolution of patent disputes.
