Samsung Surpasses 2,000 Patent Approvals in China in Q1 2026, Driven by AI Memory and Advanced Chips

Samsung Group secured more than 2,000 patent approvals in China during the first quarter of 2026, signaling an aggressive push to strengthen its intellectual property portfolio in the world’s second-largest economy. According to a TrendForce report citing Korean media outlet The Guru, Samsung’s total approved patents in Q1 reached 2,083, up approximately 7.8% year-on-year from 1,933 in the same period of 2025.

The monthly breakdown reveals January at 731 approvals, February at 483, and March at 869, making March the strongest month of the quarter. By subsidiary, Samsung Electronics led with 418 approvals in March alone, followed by Samsung Display (231), Samsung SDI (183), and Samsung Electro-Mechanics (35). The distribution points to a concentrated IP strategy across semiconductors, displays, and energy storage.

China’s Patent Boom

Key AI and Memory Patents

Among the most notable approvals are patents addressing AI infrastructure challenges. As TrendForce reports, the patent titled “Method for reducing memory usage in large language models and electronic device performing the same” (CN121745186A) targets memory bottleneck reduction during LLM inference. With the operational cost of running large language models becoming a global industry challenge, securing patent rights over memory efficiency techniques directly supports Samsung’s competitive position in the data center market.

Another significant patent is “CXL memory controller, its operation method, and CXL memory device” (CN121597613A). CXL (Compute Express Link) is emerging as a foundational interconnect standard for next-generation data center architectures. Combined with Samsung’s HBM (High Bandwidth Memory) business, this patent positions the company at critical nodes across the entire AI semiconductor ecosystem.

3D Semiconductors and Display Technology

In manufacturing technology, “Three-dimensional semiconductor device and manufacturing method thereof” (CN121751630A) stands out. Vertical stacking technology is central to meeting rising demand for higher-capacity, high-speed processing in the AI era, directly aligning with Samsung’s semiconductor division strategy for advanced 3D packaging.

On the display front, Samsung Display’s patent portfolio has effectively established significant barriers to entry. According to industry sources cited by Global Economic News, patents covering OLED emission layer structures and LTPO (low-temperature polycrystalline oxide) driving technology have built formidable competitive moats. Specific approvals include “Composition, thin film, and electroluminescent device” (CN121628058A) and “Electroluminescent device, manufacturing method thereof, and display device” (CN121646122A), both targeting emission material performance and overall device architecture optimization.

Strategic Implications Under Geopolitical Tension

Samsung’s China patent strategy must be understood against the backdrop of the U.S.-China technology rivalry and semiconductor export controls. While the U.S. Bureau of Industry and Security continues to tighten restrictions on advanced chip technology exports to China, Samsung maintains its Xi’an facility for NAND flash memory production. Complete decoupling from the Chinese market remains impractical.

The expansion of Samsung’s Chinese patent portfolio serves at least three strategic functions. First, it provides IP defense for manufacturing and sales operations within China. Second, as Chinese domestic chipmakers grow rapidly, patents make Samsung’s technological advantages visible and enforceable, laying the groundwork for licensing negotiations or infringement actions. Third, Chinese patents may serve as bargaining chips in future SEP (standard-essential patent) and cross-licensing negotiations.

What to Watch Next

TrendForce also reports that NPEs (non-practicing entities) are increasing pressure on Samsung and SK hynix through HBM-related patent assertions. As the AI semiconductor patent landscape grows more complex, the importance of defensive filing strategies is rising sharply.

The Q1 2026 figures demonstrate that Samsung is not merely a manufacturing powerhouse but is positioning itself as a leading force in IP strategy for the AI era. Patent filing trends in Q2 and beyond, along with shifts in examination practices at CNIPA (China National Intellectual Property Administration), warrant close monitoring.
