Samsung Display's Section 337 Investigation Concludes in Preliminary Ruling Against Patent Infringement Claims

Samsung Display Co., Ltd.'s Section 337 investigation before the United States International Trade Commission (ITC), concerning alleged OLED patent infringement, has concluded in a preliminary ruling. The ITC administrative law judge found no violation of Section 337 of the Tariff Act of 1930. This decision has significant implications for Samsung Display, the 17 mobile phone repair screen manufacturers involved in the investigation, and the entire OLED industry chain.

The Section 337 investigation stemmed from a complaint filed by Samsung Display on December 28, 2022. Samsung Display accused 17 mobile phone repair screen manufacturers of infringing its OLED patents and requested the ITC to issue a general exclusion order (GEO), a limited exclusion order (LEO), and a cease and desist order (CDO) to prevent these manufacturers from importing OLED repair screens into the United States. The ITC officially launched the investigation on January 27, 2023, drawing considerable industry attention.

Under Section 337 of the Tariff Act of 1930, ITC Section 337 investigations aim to determine whether imported products infringe US intellectual property rights or engage in unfair competition. A finding of violation can lead to exclusion orders prohibiting the import of the relevant products into the US, or even cease and desist orders with associated penalties. This presents a substantial commercial risk for companies reliant on the US market.

Samsung Display's initiation of the Section 337 investigation aimed to protect its OLED patents and maintain its competitive advantage in the US market. OLED technology, a high-end display technology, is widely used in smartphones, televisions, and other devices, making it a fiercely competitive market. As a leading OLED manufacturer, Samsung Display's patent protection strategy reflects its strategic market positioning.

However, the ITCs preliminary ruling challenges Samsung Display's claims. The administrative law judge's finding of no violation suggests that Samsung Display's evidence was insufficient to support its allegations. This means not only that the 17 investigated mobile phone repair screen manufacturers can continue importing their products into the US, but also that Samsung Display may have shortcomings in its patent protection strategy.

BOE Technology Group (BOE), a major Chinese display panel manufacturer, actively intervened in the investigation on February 22, 2023, with its application approved by the ITC administrative law judge on March 13, 2023. BOE's intervention demonstrates its proactive approach to international trade disputes and adds a new dimension to the investigation.

Industry insiders report that Chinese OLED panel manufacturers currently do not sell OLED screens specifically for repair purposes to brand clients. This reality highlights the complexity and potential points of contention in Samsung Display's lawsuit. If the ITC ultimately rules in favor of Samsung Display and issues a general exclusion order, it would not only affect the 17 investigated manufacturers but also ripple through the entire OLED industry chain, particularly the US OLED screen supply chain. Downstream clients would struggle to source OLED products from other manufacturers for official service, impacting supply chain stability.

Furthermore, industry sources reveal that BOE, along with other Chinese panel manufacturers, has filed Inter Partes Review (IPR) petitions against Samsung Display's patents involved in the Section 337 investigation. Five IPR petitions have been successfully filed, though the final results are pending. This proactive step demonstrates Chinese panel manufacturers' commitment to protecting their interests and handling international patent disputes.

The initiation of IPR proceedings adds uncertainty to the Section 337 investigation. If the IPR proceedings ultimately invalidate Samsung Display's patents, the Section 337 investigation will face greater challenges and may even result in a loss for Samsung Display. This would affect not only Samsung Display's market position but also the overall OLED patent landscape.

In conclusion, Samsung Display's Section 337 investigation is not just a patent dispute but a significant test for the OLED industry chain. While the ITC's preliminary ruling is unfavorable to Samsung Display, it does not conclude the case. Subsequent IPR proceedings and the final ITC decision will continue to shape the OLED industry's structure and development. The active participation of BOE and other Chinese panel manufacturers signals the increasing influence and resilience of Chinese companies in international competition. The final outcome of this patent battle will undoubtedly significantly influence the future development of the global OLED industry. Further developments warrant close attention, and we will continue to closely monitor and report on this case.
