“Netlist claimed that Samsung's infringement was intentional and requested that a provision be claimed up to three times the amount of damages under U.S. patent law should also be applied. This is a more aggressive approach than existing DDR4 or DDR5-based lawsuits”
Seoul=Yonhap Infomax) Reporter Kim Kyung-rim = Netlist, a patent management corporation (NPE) in the United States, raised its knife to target Samsung Electronics' high-bandwidth memory (HBM) product line. The industry believes that Netlist filed this lawsuit after long-term preparation, and is analyzing it as a strategy to maximize royalty returns through intellectual property rights (IP) for semiconductor core technologies.

According to the relevant industry on the 21st, Netlist filed a patent infringement lawsuit against Samsung Electronics and its subsidiaries in the United States in the Texas Eastern District Court on the 19th (local time). (?Refer to the article "'This time HBM3'... U.S. Netlist filed a patent lawsuit against Samsung Electronics again' sent by Yonhap Infomax at 14:16 on May 20)

The technology in question is U.S. Patent No. 12,308,087 (hereinafter referred to as '087 Patent), and the registration process was completed as of the 20th, the day after the collection was received.

The fact that a lawsuit was filed just before the patent registration can be interpreted as meaning that Netlist has been preparing legal disputes with Samsung Electronics for a long time, such as securing pre-registration numbers in advance.

This patent is about 'layered memory' technology, and the key is how to send and receive signals in a structure that stacks multiple DRAM chips and controls them. In particular, the main content is how to effectively distribute signals to each memory chip and to process command signals and data signals separately.

Netlist claims that HBM3E, Samsung Electronics' latest memory product, is using this patented technology as it is. Samsung Electronics is using a method of applying multiple layers of DRAM dies to HBM3E and sending and receiving data through a vertical channel (TSV) that connects the chips. The Netlist's position is that this is essentially the same as the composition described in the claim of the '087 patent.

The industry is paying attention to the time of the lawsuit. Previously, Samsung Electronics passed the HBM3E test from Nvidia in February, and Netlist applied for a patent for the technology in 2022 and completed registration this month. The fact that the lawsuit was filed immediately before the registration process of the applied patent was completed is evidence that Netlist was watching the time when it passed the HBM3E quality test of related technologies and Samsung Electronics.

In particular, based on the experience of winning the jury verdict in the cloud computing-related memory lawsuit last year, this time it is interpreted as a strategy to secure additional profits from HBM3, Samsung Electronics' flagship product, as well as compensation for damages.

Netlist claimed that Samsung's infringement was intentional and requested that a provision be claimed up to three times the amount of damages under U.S. patent law should also be applied. This is a more aggressive approach than existing DDR4 or DDR5-based lawsuits.

An industry official said, "Netlist's new patent seems to have subdivided technical design elements," and "there is definitely a structural similarity with commercialized HBM products."
