Core Viewpoint - The USPTO has denied the IPR request from Tianma Microelectronics to challenge LG's patents, reflecting a trend of rejecting challenges from Chinese companies based on procedural and policy considerations rather than technical validity [1][3][4]. Group 1: Legal Proceedings - In June 2025, LG Display filed a lawsuit against Tianma, alleging infringement of multiple patents in mobile LCD, OLED, and automotive display sectors [3]. - Tianma responded by filing a counterclaim and an IPR request with the USPTO to challenge the validity of LG's patents [3]. - The USPTO previously rejected Tianma's IPR request in 2025 and reaffirmed this decision on March 18, 2026 [1][3]. Group 2: USPTO's Rationale - The rejection of Tianma's IPR request was based on the involvement of the Aviation Industry Corporation of China, which holds approximately 10% of Tianma's shares, leading to concerns about potential foreign government influence [5]. - This decision indicates that compliance and background factors are becoming increasingly significant in patent disputes in the U.S., beyond just technical considerations [5]. Group 3: Implications for Patent Disputes - With the IPR pathway blocked, LG's patents remain valid, and Tianma loses a critical avenue to directly challenge these patents [5]. - The focus of the ongoing court proceedings may shift back to the core issue of patent infringement, highlighting the importance of compliance in patent defense strategies [5].

Core Viewpoint - The article discusses a patent dispute between two leading companies in the domestic storage industry, Shenzhen Jiangbolong Electronics Co., Ltd. and Shenzhen Baiwei Storage Technology Co., Ltd., highlighting the implications for the industry and the ongoing trends in patent litigation and technology competition [1][2]. Group 1: Patent Dispute Details - Jiangbolong's subsidiary, Yuan Yuzhi Technology, filed a lawsuit against Baiwei Storage for patent infringement, seeking compensation of 1.21685 million yuan [1]. - The patents in question relate to core technologies for eMMC storage devices, originally owned by Nokia and later transferred to Jiangbolong's affiliates [1]. - Baiwei Storage asserts its compliance with FRAND principles during negotiations and claims insufficient legal basis for the lawsuit [1]. Group 2: Financial Impact and Industry Trends - The amount in dispute represents only 0.79% of Baiwei Storage's Q1 2025 revenue of 1.543 billion yuan, indicating a limited immediate financial impact [2]. - The eMMC technology at the center of the dispute is a mainstream solution in the embedded storage market, with Baiwei Storage's revenue in AI edge storage exceeding 1 billion yuan in 2024, reflecting a 294% year-on-year growth [2]. Group 3: Legal Considerations - The case may focus on three key legal issues: whether the implementation of standard-essential patents constitutes infringement, the reasonableness of licensing fees under FRAND principles, and the conditions for applying injunctions [3]. - Baiwei Storage plans to file for a declaration of patent invalidity and continue developing high-end products like LPDDR5X and PCIe5.0 [3].
